Note: There should be 1 to 2 cm (1/2 to 3/4 inch) slack in the chain, measured midway between the sprockets.
-
Park the machine on a level surface and disengage the auxiliary hydraulics.
-
Shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operating position.
-
Remove the drive chain cover (Figure 6).
-
Loosen the 2 hydraulic motor, mount-plate bolts (Figure 6).
-
Using the adjuster bolt, move the hydraulic motor upward to tighten the drive chain (Figure 6).
-
After you have set the chain to the proper tension, tighten the adjuster bolt and hydraulic motor mount-plate bolts (Figure 6).
Note: When you can no longer set the chain to the proper tension using the adjuster bolt or if chain failures repeatedly occur, replace the chain.
-
Install the drive chain cover.
Replacing the Tiller Tines
Maintenance Service Interval | Maintenance Procedure |
---|---|
Before each use or daily |

Note: Worn or dull tines degrade the performance of the tiller.
-
Park the machine on a level surface and disengage the auxiliary hydraulics.
-
Shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operating position.
-
Install tines so that there are 2 left tines and 2 right tines on each hub (Figure 7).
Note: The cutting edges of the tines should face toward the rear of the tiller.
-
Torque the tine-mounting bolts to 85 to 104 N-m (63 to 77 ft-lb).
Checking the Hydraulic Lines

Warning
Hydraulic fluid escaping under pressure can penetrate skin and cause injury. Fluid injected into the skin must be surgically removed within a few hours by a doctor familiar with this form of injury; otherwise, gangrene may result.
-
Keep your body and hands away from pinhole leaks or nozzles that eject high-pressure hydraulic fluid.
-
Use cardboard or paper to find hydraulic leaks; never use your hands.
