Adjust equal- izing screw until front and rear lining has equal clearance on brake drum. With this adjustment any drag will be eliminated. Do not adjust brakes at pedal rod. Refer to hitching height, implement instruction book. The line of draft effects steering and traction. It can also cause the drawn implement to put excessive load on the tractor. The pins may be removed from the sides of the tractor drawbar and the drawbar allowed to swing.

This will allow easier steering on sharp turns with heavy loads. The tractor drawbar may be raised or lowered, by removing the pins in the bail support and reinstalling in the desired position. The drawbar is adjustable in length and should be set to extend 14 beyond the end of the P. Use short position for all drawbar work when P.

Drawbar must be perfectly free to,slide when using drawbar control. When drawbar control is not used keep drawbar clamp tightened to eliminate wear on drawbar and keep universal joints in alignment.

Select the position most convenient for operator. You can make simple adjustments adjustment made does not improve the condition, on your tractor that will improve its operation return to the original setting before proceeding and save you the time and expense of engaging a to the next adjustment.

Leave radiator and fuel caps slightly loose oil. Turn screw I3 into pump body, separat- ing plates. Turn volume screw D out against stop. Set hand lever at top of quadrant. Loosen set screw at top of long rod. Push down on rod to take out slack and tighten set screw.

Added rod length can be gained by reducing bend in rod. Start tractor and extend rams. Shut off tractor. Push down on ram arms while lowering the hand lever slowly. A magnetic drain plug is gauge. The filler plug for the hydraulic located at the bottom of the housing. This system and belt pulley compartment is located plug should be cleaned periodically. When on the left side of tractor and is the upper completely draining,the pump drive housing, forward of the three filler plugs.

Refer to the pump control housing must also be drained, : lubrication guide, as oil trapped in pump control housing cannot be drained by removal of the magnetic plug. Loosen set screw in short rod. Turn plates and lock together with screw B I, being careful not to move hand lever, Rotate plates to detent position. If link rod is too long it will decrease maximum load. If it is too short, it may break control linkage. Lock set screw in short rod securely. Check drawbar control linkage by first loosening both capscrew at front of drawbar spring and noting distance between cap and adjusting washers with sprin at free length.

If unit will not lift, lifts slowly or maximum load cannot be obtained, recheck linkage adjustment. Be sure drawbar is free to move forward and back without binding. Turn Screw B into body sepa- rating plates. Turn Screw D out as far as possible. Turn Screw B out of body lock- ing the plates together. Turn Screw D out as far as pos- sible. Turn Screw A into body. Turn Screw B out of body lock- ing plates together. Turn Screw C in to secure de- layed lifting of rear cultivator bar.

Turn Screw D in to get further delay. To delayed lift. Select the setting most suited to do so may drop implement and cause injury to job. This chart is also on the side of the battery person making adjustments or nearby persons.

However, to adjust,! To Operate Lift and Lower: Set pump for lift position. Raise hand lever to top of quadrant to lift. Pull hand lever to bottom of quadrant to lower. This screw locks out drawbar regulation. Turn screw 8 until the two plates are locked together and screw is free of housing. These plates operate against a detent ball and spring which can be felt on the hand control lever. Turn screw C out against stop.

Turn screw D out as far as possible. With the pump in this position the front and rear gangs will lift together or the rear gang may lift first.

If when screw! Z has been turned in as far as possible there is still uncultivated ground between the place where the front gangs lifted the place where the rear gangs lifted screw D may be adjusted. This screw cuts down the output of pump and will increase the delay between the front and rear gangs.

It is pos- sible to turn this screw too far or far enough to prevent pump from delivering oil. To Operate Delayed Lift Raise hand control lever to top of quadrant to raise both front and rear gangs.

To lower- move hand control lever down until detent ball is felt on hand control lever. This drops the front gang only. When the tractor moves forward until the rear gang is above the spot where front gang was lowered the hand control lever may be pushed to bottom of quadrant, lowering rear gang. Turn Screw 3 out of body lock- ing plates together. If the rate of lift is too fast, screw D may be turned inward to slow lift. To Operate Under Hold Position Set pump for hold position, To lower imple- ment, move hand control lever down past the hold or detent position a catch on quadrant will be noted at hold position , With the lever in the detent position the pump is actually in the lowering position and the load on the ram is held by the check valve in the hold position valve assembly.

To lower, move the lever down until desired depth is reached and then return lever to detent position to hold ram at required setting. To raise, move lever up until desired lift has been secured and then return lever to detent position to hold ram in desired position.

The hold position valve enables the operator to control the remote ram and hold it in any position or partial extension. To Obtain Drawbar Control Set the pump for drawbar control to regulate depth and gain weight transfer. For an example on the pickup plow move the hand control lever to the bottom of quadrant and set the plow through the beaming and winging screw to plow the desired depth and to do the job of plowing you want it to do Refer to Plow Instruction Book.

Then slowly, while plowing, move the hand control lever up on quadrant until the slack is just taken out of the lift links. If the pull becomes greater, the plow, through the hydraulic system, has a tendency to raise; the weight of ground plus the weight of plow through the linkage is transferred to rear wheels providing more traction to get through this tough spot which created the additional drawbar load.

Turn Screw 3 out of body lock- ing the plotes together. Turn Screw 9 o as for OS pos- sible. Turn Screw D out os for os possible. RAMS - The two lift rams are connected to the rear lift shaft assembly. The left hand ram may be installed with the ram mounted for- ward so that both front and rear tools can be lifted.

When a ram is used in connection with hold position the ram hose must be attached to one of the forward holes closest to screw C I. Ram packing nuts require only a light pressure for sealing. Do not over-tighten. To disconnect pull ring on coupler towards center of coupler and detach hose.

To install, depress ring and move hose into place. Releasing ring will fasten hose. The hose is equipped with check valves to close end of hoses when uncoupled preventing loss of oil. Hose removal should only be made when the ram is collapsed and line is without pressure. A ramanchor bolt of special material is used.

Keep these bolts tight. When the hose is removed, keep the protector caps in place. When reinstalling hose be sure the parts are perfectly clean and that dirt does not enter system.
