(3) Tintinara Engineering Services AN INTRODUCTION TO SOIL CONSERVATION BY BLADE PLOUGHING STUBBLE RETENTION? Ploughs are the product of many years experience in the stubble retention cultivation practice. Your purchase of a Blade Plough could indicate your acceptance of a growing union that traditional farming practices are destroying our heritage, and costing an enormous amount of money in resources. Add to this the direct loss of moisture through increased run off, and the evaporative effect of wind movement near the soil surface, and you can see the need for stubble retention. The retention of crop residue on the surface after harvest is the best basis upon which to start a soil Conservation programme. This residue cover reduces the drop impact, which causes sealing of the soil surface and allows the water to run off. If the surface remains open there is increased water in take, similar in effect to a sponge. Erosion by wind is also greatly reduced, because the trash cover reduces the wind velocity over the ground surface, reducing the amount of movement of soil particles. Also, the trash will trap and hold any soil that is moved. This concept was used to hold soil from drifting in the U.S.A. and Canada during the "dirty thirties". Soil movement from wind became so bad in that period that straw had to be imported to the prairie regions and spread over the badly eroded areas. This was to allow plants to germinate in order to give soil cover. The reduced movement of air over the soil has the added advantage that moisture is not carried off as vapour. Soil temperatures are also greatly reduced by the body of residue, which means that summer weed germination is greatly reduced in most conditions. It can be seen therefore, that there are many sound ecological and economic reasons why stubble retention should be understood and practised. WHY NOT USE A CHISEL PLOUGH? The advocates of Chisel Ploughs claim that the implement will do everything that a Blade Plough can do; and do it better. However, they make no mention of several basic facts embodied in the stubble retention technique. 1. The direct loss of moisture allowed by opening up soil in a rubbly or lumpy state and exposing it to sun and wind. Large amounts of valuable moisture are lost in this way by every tine that passes through the soil. A Blade Plough works under the surface with a tine every 1.5 to 1.8 metres (5-6 feet) not every 0.3 metres -(1 foot), with little disturbance to the soil surface of structure. There is practically no mixing of the dry surface with the moist lower worked soil. 2. Chisel Ploughs cannot work in large bodies of straw, particularly if vines or heavy weed growth are present. With the aid of the coulter to cut through vines and trash, Blade Ploughs are capable of being used in a far wider variety of conditions than those suitable for Chisel Ploughs. Trash should be retained on the surface and not incorporated into the worked ground. This can be managed quite effectively with a Blade plough, but not with a Chisel Plough. Blade Ploughs incorporate approximately 10 % of the residue at each working, whereas Chisel Ploughs incorporate 25% or two and a half times as much. This in effect, means that the higher the percentage of trash incorporated in the soil, the greater the percentage of available nitrogen is required as amino acid to break down the incorporated residue.
(4) Root disease is more likely to occur where residues have been incorporated. Where these disorders have been a problem, mixing crop residue into the soil should be discontinued. For the best ecological and physical results, RESIDUES SHOULD BE KEP T ON THE SURFACE. 4. The argument that Blade Ploughs can only be used in clean, stump or stone free country is no longer valid. The TESHBC Series Flex Frame Blade Plough can be used in LIGHT TO MODERATE stump or stoney areas, providing that care is taken when encountering hazardous conditions, and speed is adjusted accordingly.
This is the case even with 16" sweeps. Machines with greater distance between ranks or with more Than three ranks of tines are more subject to this fault. Blade Ploughs are in some instances more difficult to operate than conventional type implements, but a few operating hints will help to overcome any disadvantage in such circumstances. At all times it should be remembered that there are very good reasons for perseverance. WHEN SHOULD BLADE PLOUGH BE USED Blade Ploughs are both primary and secondary tillage implements, and as such can be used immediately after harvest, to kill weed growth and loosen the soil to accept water penetration. The blade many be used for all subsequent working with excellent results for moisture and trash cover retention. The after harvester working at a depth of 75mm to 10Omm (3"- 4") to penetrate under the crown of the stubble, and open the soil without destroying the protective trash cover, should be regarded as the most important. Proper blade penetration at this time is essential to allow the stubble to stand erect for as long as possible, with as much soil attached to the old roots as is practicable. This attached soil will hold much better against the forces of water and wind erosion. HOW CAN THE WEED KILL BE IMPROVED? The blade is designed to give a minimum surface disturbance. This means that in certain conditions sufficient soil may not be shaken from the plant roots to stop growth. To reduce this problem the addition of drag rods, or a dead rod weeder may be added. These will shake the soil from the roots, BUT FOR MAXIMUM STUBBLE AND MOISTURE RETENTION THEY SHOULD ONLY BE USED WHEN NECESSARY. It is true that in comparing the weed kill of a Scarifier or a Chisel Plough with a Blade Plough Not using dead rods or drag rods, the former will give a better kill on weeds that are cut out and not skipped over. However this will be at the expense of moisture retention, much of which is lost by air penetration through the soil when worked in this manner. Boom spraying of selective weedicides which effectively kill the weeds without contamination of the soil, are rapidly gaining increased support. This type of kill after blading leaves the trash cover intact and thus conserves the ecological balance, complementing the Blade Plough stubble retention cultivating practice. 'HOW DEEP SHOULD THE COULTER BE SET? The coulter is provided to cut through vines and trash so that wrapping around the blade standard does not occur. Vine or trash wrapped around the standard will open a trench behind the machine, allowing the soil to dry out. The coulter should be set no deeper than is necessary to cut through the trash. NEVER set the coulter deeper than 25mm (1") below blade depth, as it is possible to carry the weight of the plough on the coulter, thus preventing blade penetration. In many cases the coulter should NOT be used, such as in stumpy or stoney conditions where the weight of the plough is constantly being thrust onto the coulter, as damage can occur. (5) WILL A NOSE DOWN ATTITUDE HELP PENETRATION? Blades should ALWAYS be worked LEVEL to obtain an even seed bed and even wear. Wear on the blades should be checked periodically to ascertain if the correct attitude is achieved. As blades wear, the front of the machine should be lowered to maintain the level, however there are exceptions to every rule. In certain loose type soils and in soils that tend to push, a slight tail down attitude will assist in stopping roots from wrapping around the wings of the blade. If wrapping does occur a heel down attitude causes more weight to be applied to the wings, giving a greater cutting or shedding ability, WHAT CAUSES THE BLADE TO BLOCK OCCASIONALLY IN STUBBLE? There are a number of reasons why a blade will block, but generally these can be over come with a little understanding. Blockages usually only occur in initial workings where certain simple rules should be observed.
3 . Angling across harvester tracks will in most cases eliminate blade plugging, and also eliminate those compacted areas. This will give better weed control and a more level finish.
WHAT CAN BE DONE TO GET PENETRATION IF THE GROUND IS HARD? NEVER allow the blades to become worn down to such a degree that wear is showing on the blade support. This not only destroys part of the plough, but also when working in wet conditions, and with worn blades mud will pack up under the blade support and make penetration impossible. In very hard ground the blade may skate across the surface, and straw can wrap around the blade causing a block. If this occurs, inspect the blade for wear. Should the makers edge be worn away, or if the front lip of the blade is worn more than the back edge, allowing a ski effect, it is very difficult to obtain penetration first time over. In this case, new blades should be fitted for the initial working and them worn blades saved for subsequent workings. When new blades do overcome the problem, AND COULTERS ARE NOT SET TOO DEEPLY, Then more weight may be added. The addition of an extra 110 Kg (250 lbs) of weight per section should allow penetration in most circumstances. However, when not needed this extra weight should be removed, since extra weight will cause much more stress to be applied to the componentry if the plough should strike an object. When the plough is set correctly, and with the addition of extra weight, it should penetrate as well as any other equivalent machine. In stumps or impeding stoney conditions, use of extra weight should be avoided if at all possible, and speed should be reduced. WHAT CAN BE-DONE IN EXTREME CONDITIONS? If conditions are such that the above recommendations do not allow the machine to penetrate in extremely hard conditions, blades and supports should be removed, and 406mm (16") or 608mm (24") Buster Blades and supports fitted. These will penetrate hard soils beyond that which can be penetrated by Chisel Ploughs. WHAT BLADES SHOULD BE USED? Hardfaced blades are recommended where the chance of stump or rock encounter is very low. The recessed hardfaced inlay is made of material which is ultra hard, and thus is prone to chip or crack easily when contacting hard objects. Much less blade wear has resulted from the use of hardfaced blades over plain blades in some areas. Hardfaced blades will in most cases maintain a keener edge in tight soils, and during initial break up, thus aiding penetration. Plain blades are recommended in areas where stumps and stones are known to exist as they will stand up to much more impact without damage. (6) WHAT SPEEDS CAN BE USED? Under normal conditions a speed of from 7 kmh to 10 kmh (4 to 6mph) usually gives the best weed kill by loosening the soil from the weed roots. Remember however, that high speeds on any tillage tool shortens it wearing life, and compounds the stress on the implement. Where stumps and stones are prevalent, speed must be reduced to NOT MORE THAN 7kmh (4mph). Too high a speed under these conditions will cause breakages. WHAT WILL HAVE TO BE DONE TO GET CULTIVATIOIJ READY FOR SEEDING? There is presently available local and imported seeding equipment than can sow into a considerable amount of trash. The major problem has been in keeping sufficient trash through the fallow, not how to break it down. This becomes more noticeable after a few seasons, as the microorganisms in the soil increases. However, should you encounter the problem of too much trash in initial years for conventional seeding equipment, a high speed harrowing usually suffices. CONCLUSION MOISTURE NEEDS FOR EFFECTIVE PRODUCTION It is generally accepted world wide statistic that 100 kilolitres (22,000 gallons) of water are needed to produce 27 kilograms (1 bushel) of grain and almost 2,275 kilolitres (500,000 gallons)' of water per acre to produce a 20 bushel crop. The maximum conservation of moisture in dryland Australia should therefore be of prime concern. However, the higher the amount of retained moisture in the soil profile, the lower the infiltration rate per unit of time. Thus the higher the stored moisture level, the greater the need for surface trash to allow precipitation to infiltrate without run off Carryinq soil away. This is most important towards seeding time. LONG TERM UTILIZATION OF OUR SOIL RESOURCES This will be dependent upon the maintenance of our arable lands, particularly in the higher rainfall areas which are more suitable for crop productions - 304mm to 76Omm yearly average (12" to 30"). The North American claim that a 12.5 tonne per hectare (5 ton per acre) annual soil loss from cultivated farmland is acceptable. This is equivalent to 0.8inm (l/32") thickness of soil. It is estimated that on areas of five percent slopes, it is not uncommon to have 32 tonne per hectare (13 ton per acre) of soil removed in a single rainstorm. Water and wind erosion have reached calamitous proportions in the majority of grain producing areas of Australia, and losses will continue until positive action replaces wishful thinking. ASSEMBLY A minimum of assembling is required to the HBC Series Blade Plough as they are completely assembled prior to forwarding to their destination. However, some components are usually removed for transport purposes and these will need to be re-assembled, and the wings lowered. The raised wings may be lowered by any suitable means available, such as a front-end loader, mobile crane, forklift, block and tackle, or similar mechanical devise. EXTREME CARE MUST BE TAKEN WHEN CUTTING WIRES AND LOWERING WINGS! NEVER STAND BENEATH RAISED WINGS OR ALLOW ANYONE TOO NEAR WHEN LOWERING. Release hinged standard before or during lowering of wing so that it will he in position when lowering is completed, and replace the shear bolt. Examine any shear bolts that were not removed before transportation, and replace any that may have been damaged in transit. When assembling blades, ensure that the surface of the blade support is clean and free from lumps of any kind that would prevent the blade from fitting flatly against the support throughout its entire length.
(7)
It is important that the nose of the blade support is fitting snugly into the vee of the blade nose when the front bolts are tightened. ALWAYS tighten the two front bolts FIRST, and then progressively tighten from the point of the blade to the rear wing tips. When tightening the bolts make sure that the bolt heads are well seated, by striking the head with the ball of an engineers hammer, and then tightening to maximum torque. The TESHBC5 Blade Plough will have had the outer wings removed for transportation. To reassemble, manoeuvre one wing at a time into position and bolt the inner and outer wings together at the two pivot points. Then connect up the two outer turnbuckles to their respective torsion tubes, and finally connect the two wing lift rams to their anchors. If coulters are to be used, attach the mounting brackets to the beams directly in front of each blade point, using two M16 U bolts with nuts and spring washers for each mount. Attach the coulter assembly to the fork and tighten the shoulder nuts, slide the fork and locking collar onto the mounting bracket arm and lightly tighten locking collar. Test fork for free swinging movement on mounting bracket, and relieve between the two bearing sleeves of the fork if tightness occurs. It is important that the coulter forks are free to swing on the mounting brackets; otherwise difficulty could be experienced in keeping the locking collars tightened securely in position. Set coulter blade for:
moving the bracket on the front beam. NOTE! Re-alignment of the coulter may have to be made after commencement of ploughing to ensure that the cut corresponds with the CENTRE of the leading edge of the standard. Poor alignment can cause soil build up on one side of the standard in some conditions, and may contribute to unnecessary trenching behind the standard. (b) Correct depth; no deeper than is necessary to cut through vines and other trash that would otherwise build up around the standard. Ensure that all coulters are set equally; depth is set by loosening the grub screws in the locking collar, and sliding the forks up or down. Finally tighten all U bolts and locking collars securely. A hydraulic wing lifting kit is available for the TESHBC3 Blade Plough. Figures 1 and 2 show the lifting components relative to a wing in the raised position. First assemble a lift bracket (A) and clamp plate (B) to the centre frame rear left hand beam. Use an M16 U bolt and 0.16 spring washers over the clevis plates, two M16 x 150 bolts with 0.16 spring and plain washers in the slotted holes, and an M20 x 150 bolt with 0.20 spring and plain washer at the stay end. Assemble a hydraulic hose rear clamp bracket (C) above the stay before bolting. Next assemble a pivot arm (D) in the lift bracket, using two pivot pins (E) secured by four 0.24 plain washers and four 0.5 x 40 split pins. Check that the pivot arm moves freely in the lift bracket. Now bolt a wing support bracket (F) to the left hand side of the centre frame front clevis member, using four M16 x 150 bolts, two clamp plates (G) and four 0.16 spring washers. Place a locking pin (H) through the holes provided in the vertical section of the support bracket, and secure with a grip clip. NOTE! The locking pin is positioned in the support bracket clevis after the wing is raised, to Provide a safety lock in the event of hydraulic failure. Repeat the above assemblies on the right hand side of the Plough. In the illustrated parts sections of the manual, plate A7 shows the hydraulic layout for both lifting the plough, and raising and lowering the wings. Connect the hydraulic rams (ref. 14-15) to the lift bracket pivot arms, and the fixed anchors on the wings, with the piston rod clevis connecting to the wing. Assemble hoses, (ref 3,4 & 13) hydraulic fittings, (ref. 2 & 5) and clamps, (ref 1 & 18) and appropriate bolts, nuts, and washers. Couple hydraulic hoses to the tractor, and raise and lower wings. Adjust wing support brackets so that wings do not exceed 90deg when raised, this will ensure correct locking at wing support, and provide clearance between lifting bracket and wing frame as shown in Fig.l. (Page 12) (8) On the HBC5 Blade Plough, the setting of the support brackets (F) should be checked by raising the wings and verifying that the angles between the inner and outer wing frames are 90deg as shown in Fig. 2. (Page 12) This will ensure clearance between lifting brackets and inner wing frames as shown in Fig. 3. (Page 11). LEVELLING Correct levelling of the TESHBC Series Blade Plough is of extreme importance and can not be over emphasised if the operator is to obtain satisfactory performance and provide an even seed bed
(9)
The levelling process should be carried out systematically to be fully effective. The recommended procedure has been divided into three basic stages which are given below: "A" Levelling frame, fore and aft. "B" Levelling axles in relation to the frame. "C" Levelling blades in relation to frame. Each stage should be carried out in the sequence given, and work finished on one stage Before proceeding to the next. There may however, be need of a further fore and aft levelling at the time when the blade depth is being established. A step-by-step method of instruction for each stage is provided to simplify the procedure and assist the Operator. "A" LEVELLING THE FRAME FORE AND AFT. (2,3 & 5 Blade Ploughs) 1. First hitch the plough to the tractor. Note that there are three height positions available; choose the position appropriate to the tractor drawbar. 2. Check the tyre pressure, inflate or deflate each tyre until all tyres are at the correct pressure 350kPa(50 p.s.i.). 3. Now position the plough onto reasonably level ground, and ensure that there are no obstacles present which would prevent any blade from making full contact with the ground. 4. Finally, adjust the turnbuckle on the front hitch until the frame is parallel to the ground, with the blades just clear of the ground. "B" LEVELLING THE AXLES IN RELATION TO THE FRAME (5 Blade Plough) 1. Ensure that all three hydraulic ram adjustable mounts are EQUALLY ADJUSTED in a mid thread position, measured from the face of the fixed anchor (behind the locknut) to the front of the ram clevis pin. Set the distance at 170mm as shown in Fig. 4.
2. Adjust the hydraulic ram depth stops until they are completely closed and remove any split spacers that may be fitted to the piston rods. 3. Operate the rams by extending and retracting them a number of times to purge air from the system. 4. Now retract the rams once more until there is sufficient space under each wheel to place 10Omm (4") high blocks in position, with the wheels still free to revolve. NOTE! All Blocks MUST be of the same height. IF BLOCKS ARE UNAVAILABLE REFER TO ALTERNATIVEMETHOD PAGE 14
(10) 5. With the wheels still free to revolve, place a straight edge across the centre frame so that it is directly over the axle. Measure and note the distance from the straight edge to the top of the left and right hand axle spindles. (See Fig. 5)
Fig.5 6. If the distances differ, adjust the independently adjustable left hand axle spindle until both measurements correspond. 7. Now extend the rams to their maximum, and adjust the depth stops until they are fully extended also. Check the length of ALL depth stops from ram clevis pin to the end of the stop. See Fig 6. IT IS VERY IMPORTANT THAT ALL MEASUREMENTS ARE IDENTICAL, TO ENABLE THE RAMS TO BE SYNCHRONISED.
Fig.6 8. When all depth stops are equal, retract the rams until seated against the depth stops. The blades should now be just clear of the ground and all the weight of the plough transferred to the wheels. If this is not the case, larger blocks are required under the wheels, or if unavailable, a split spacer per ram may be added to each piston rod.
(11)
9. With the weight on the wheels, remove the two inner axle turnbuckles from the centre axle, and recheck the distance of the centre axle spindles to the top of the frames; and re-adjust if necessary. (.See steps 5 & 6) NOTE. It may be necessary to adjust the length of the turnbuckles prior to their removal to facilitate ease of withdrawal. 10. Now move to the INNER-LEFT HAND wing frame and check the measurement from the straightedge to the top of the axle spindle. NOTE! Wing frame beams over the axle are smaller than the beams on the centre frame. Allow 50mm (2") to compensate for this difference when comparing measurement of centre frame. 11. If the measurement does not correspond to those of the centre frame adjust the ram mount adjustable anchor on the wing frame until the correct dimension is achieved. DO NOT TOUCH THE DEPTH STOP SETTING! 12. Now check (and adjust if necessary) the INNER RIGHT HAND wing frame to axle measurement in a similar manner 13 Next check the measurements of the OUTER wing frames to axle spindles. These must be the same as all other frame to axle measurement. Corrections are made, by adjusting the left and right hand OUTER TURNBUCKLES until the required measurements are achieved. 14. When all frame to axle measurements are equal, it is then advisable to reduce the distance on the OUTER WINGS ONLY to 10mm (3/8") less than the other sections, to compensate for reduced weight on the outer wheels. 15. Finally, replace the inner turnbuckles, adjusting them if necessary until they fit easily into position without force being applied. Replace and tighten the turnbuckle locking brackets and screws, and also the retaining pins. Check also that ram-adjusting mounts have been re-tightened. ALTERNATIVE LEVELLING METHOD IN LIEU OF BLOCKS. If 100mm (4") Blocks are not readily available for placing under the plough wheels, an acceptable alternative is to use spacers on each hydraulic ram piston rod. A sufficient number of spacers must be added to each piston rod to enable the wheels to carry the weight of the plough, with the blades just clear of the ground, without the use of blocks. When using this method in lieu of blocks, it is ESSENTIAL that:- (a) The weight of the plough is COMPLETELY transferred, to the wheels. (b) The rams 'are at rest on the EQUALLY ADJUSTED depth stops. (See step 7). (c) Each ram has an EQUAL NUMBER of spacers, and each spacer is EQUAL IN WIDTH. "B" LEVELLING THE AXLES IN RELATION TO THE FRAME.(.3 Blade Plough) 1. Adjust the hydraulic ram depth stop until it is completely closed, and remove any split spacers that may be fitted to the piston rod. 2. Operate the ram by extending and retracting a number of times to purge air from the system. 3. Now retract the ram once more until there is sufficient space under each wheel to place 100mm (4") high blocks in position, with the wheels still free to revolve. NOTE! All blocks MUST be of the same height. IF BLOCKS ARE UNAVAILABLE REFER TO ALTERNATIVE METHOD, PAGE 16 4. With the wheels still free to revolve, place a straight edge across the centre frame so that it is directly over the axle. Measure and note the distance from the straight edge to the top of the left and right hand axle spindles. (See Fig. 7) (12)
5. If the distances differ, adjust -the independently adjustable left hand spindle until both measurements correspond. 6. Now extend the ram to its maximum, and adjust the depth stop until it is fully extended also.
7. Retract the ram until seated against depth stop. The blades should now be just clear of the (ground and all the weight of the plough transferred to the wheels. If this is not the case, larger blocks are required under the wheels, or if these are unavailable, a split spacer may be added to the piston rod. 8. With the weight on the wheels, next check the measurements of the wing flames to axle spindles. These must be the same as the centre frame to axle measurements. Corrections are made by adjusting the left and right hand turnbuckles until the required measurements are achieved. 9. When all frame to axle measurements are equal, it is then advisable to reduce the left and right hand wing frame measurements to 10mm (3/8") less than the centre frame, to compensate for reduced weight on the outer wheels. 10. Finally, replace and tighten the turnbuckle locking brackets and screws. ALTERNATIVE LEVELLING METHOD IN LIEU OF BLOCKS. If 100m (4") blocks are not readily available for placing under the plough wheels, an acceptable alternative is the use of spacers on the hydraulic ram piston rod. A sufficient number of spacers must be added to the piston rod to enable the wheels to carry the weight of the plough with the blades just clear of the ground, without the use of blocks. When using this method in lieu of blocks, it is ESSENTIAL that the weight of the plough is COMPLETELY transferred to the wheels. "B" LEVELLING THE AXLES IN RELATION TO THE FRAMES (2 Blade, Plough) The levelling procedure for the 2 Blade Plough is identical to that of the 3 Blade Plough, except that there is only one wing to adjust. "C" LEVELLING BLADES IN RELATION TO THE FPJMF, With the axles levelled to the frame, the standards and blades can now be levelled to the frame. This is achieved through the use of two eccentric cam nuts on the hinge plate at the back of each standard, and by use of spacers on the shear bolt block at the front of standard. The levelling procedure is as follows (13) 1. Check that a spacer is fitted between each standard and the frame on the hanging shear block located at the front of the standard (See Figs. 8 and 9) 2. Slacken the three retaining bolts of each hinge plate sufficiently to :)e firm but not tight. 3. Level the two wing tips in relation to each other, by rotating the eccentric nuts. The maximum permissible variance is 5mm (approx. 3/16") Pig. 8
4. Check the dimension at the front of the blade (See Fig 9) and compare with those at the wing tips.(Fig.8)The measurements must be equal, or no greater than 5mm (3/16") at the wing tips. (Fig 9) To achieve this, adjust the rear setting by rotating both eccentric nuts an equal amount. If the adjustment gained by this method is still insufficient, then spacer shims will have to be inserted at the hanging shear block between the existing spacer and the frame. NEVER REMOVE THE EXSISTING SPACER. NOTEI The blade must be parallel to the frame, or nose up, (5mm maximum Fig 9) NEVER NOSE DOWN.
5. When all measurements have been checked and corrected, tighten the three retaining bolts to their maximum. NOTE! Tightness of the retaining bolts is ESSENTIAL, they should be checked regularly as any looseness will allow adjustments to shift and thus upset the operation of the plough. (14) FIELD LEVELLING ADJUSTMENTI (5 Blade Plough) Care must be taken when making depth adjustments, that all hydraulic ram depth stops are adjusted evenly. Otherwise opposing torque forces can be created along the axles and linkages. If it is necessary to adjust any single section of the 5 Blade Plough which is fitted with a ram, then the inner 1 axle linkage (turnbuckles) should be removed from that section and the adjustment made with the ram adjustable mount, not the depth stop Replace linkage and then check the outer wings for depth, as they may have been affected by the adjustment. If it is necessary to work deeper when using buster points and there is no more depth stop adjustment remaining (or greater road and trash clearance is needed) and the rams are fully extended; adjust all the ram mounts equally back or forward to achieve the desired effect. LEVELLING 3-POINT LINKAGE BLADE PLOUGH Attach the frame to the tractor and adjust linkage arms until the frame is parallel to the ground. Adjust the depth wheels to the desired depth and lower the blade until it Ls completely resting on the ground, then commence ploughing until full penetration is achieved. Stop the tractor with the blade still in the ground and check the blade for level. Make additional adjustments to the linkage and top arms if necessary to ensure that the blade is level fore and aft, and laterally. OPERATING HINTS Always place blades on the ground and raise the wheels to cultivating depth before moving forward. This aids penetration as the weight of the machine forces the blades below the surface when the plough is moved forward. In addition, on heavily stubbled areas the blades will shear through the stubble as they penetrate to working depth, whereas if the blades were lowered while moving forward they may drag the stubble rather than cut through it. This can prevent clean cutting at working depth and cause a trench to be left behind the standard. Operate the plough at speeds between 7 and 10 km hr (4-6 mph) unless stones and stumps are prevalent. Where these hazards are known to exist, speeds should be reduced to below 7km hr. It is not necessary to raise the blades when turning, as the Blade Plough has been designed and constructed to make both left hand and right hand turns with the blades in the soil at full working depth. Keeping the blades in the ground when turning will prevent straw wrapping, which could occur if the blades were re-entering the ground while on the move. When reversing the plough, the blades must be raised clear of the soil at all times. Never set ram depth stops deeper than soil conditions will allow the implement to plough. To maintain an even working depth across the width of the 5 Blade Plough, the depth stops must carry the working draught of the plough. When using coulters, never set them deeper than is necessary to cut through the vines and other trash that would normally build up around the standard. If set too deeply in hard ground, the Coulters may reduce penetration of the blade, and be subject to heavy damage. Coulters should only be used when trash build up occurs on the standard. If there is no build up, raise the coulters to the top of the mounting brackets, or remove them completely. Remember to adjust coulters upwards as blades wear. NEVER use coulters in stoney or stump infested areas. If blades have worn down to a thick edge, and penetration is a problem, they should be replaced with new blades. When Conditions improve, or for subsequent working, the partly worn blades can be replaced and the new blades conserved. When changing blades ensure that the surface of the blade support is clean and free from lumps of any kind that would prevent the blade from fitting flatly against the support throughout its entire length. It is important that the nose of the blade support is fitting snugly into the vee of' the blade nose when the two front bolts are tightened. ALWAYS tighten the two front bolts FIRST and then progressively tighten from the point of the blade to the rear wing tips. When Tightening the bolts make sure that the bolt heads are well seated, by striking the head with the ball of an engineers hammer, and then tightening to maximum torque.

Inspect bolts for stretched threads when changing blade, and replace any doubtful bolts. Keep bolts tight at all times, and inspect regularly. The fold up screw jack that facilitates coupling to the tractor can also be utilised to remove blade supports from the standards. It will first be necessary to make up a chain puller that can be clamped to the screw jack and be hooked to the blade support. Clamp the puller above the screw jack attaching boss, and place a chain either side of the standard so that they can be hooked around the support. Then with the base of the jack against the lower part of the standard, the jack can be screwed out to force the support away from its standard. Several sharp blows to the support with a heavy hammer during the process will aid in loosening the support, care must be taken not to damage the support. If additional weight is required, extra concrete blocks can be stacked on top of existing blocks. This will require longer bolts to hold weight lid in position. Alternatively the weight lid can be inverted and whatever material is available can be added to provide the extra weight.
MAINTENANCE Check and tighten all nuts after operating for one hour, and then daily until they have settled in. Maintain a regular weekly check thereafter. Check and maintain tyre pressure at 350 kpa (50psi) Check wheel and coulter bearings weekly, and adjust as necessary. Replace blades before wear occurs on supports or bolts. (See Operating Hints for changing blades) Grease wheel bearings sparingly every fifty (50) hours of operation. Use Shell Retinax "A" grease or an equivalent. Grease upper and lower axle bearings daily. It is IMPORTANT to grease BOTH points per bearing to ensure a full spread of grease around -the bearing area. Failure to do this could cause a seizure of movement and result in damage to the torsion tube when the hydraulic lift is used. Grease weekly the wing pivot bearings, torsion bar turnbuckles, and the front hitch turnbuckle. An Application of grease to any exposed threads is also advisable. (16)
