Section 4: Maintenance and Lubrication

Maintenance

!CAUTION

For safety reasons, each maintenance operation must be performed with the tractor’s PTO disengaged, the Tiller lowered completely to the ground or on safely supported blocking, tractor engine shut off and ignition key removed.

Proper servicing and adjustment can increase the life of any implement. With careful and systematic inspection, you can avoid costly maintenance, time and repair.

After using your tiller for several hours, check all bolts to be sure they are tight.

Replace any worn, damaged or illegible safety labels by obtaining new labels form your Land Pride Dealer.

Tine Replacement

Tine Replacement

Refer to Figure 4-1:

!WARNING

Worn tines may be very sharp!

IMPORTANT: Always install tine with cutting edge facing direction of rotor shaft rotation. When ordering replacement tines, be sure to order both right and left hand tines.

1.Remove 2 bolts and nuts from tine to be replaced. Remove tine.

2.Install new tine on side of attaching flange.

3.Replace 2 bolts and nuts and tighten nuts to proper torque. See the Torque Values Chart in the “Appendix” section on page 23.

IMPORTANT: Replace tines with genuine Land Pride tines only.

Driveline Protection

Driveline components are protected from shock loads by a friction slip clutch. The clutch must be capable of slippage during operation to protect the gearbox, driveline and other drive train parts.

Friction clutches should be “run-in” prior to initial operation and after long periods of inactivity to remove any oxidation that may have accumulated on the friction surfaces. Repeat “run-in” instructions at the beginning of each season and when moisture and/or condensation seizes the inner friction plates.

Refer to Figure 4-2below and Figure 4-3 on page 16 to determine which friction clutch your Rotary Tiller has. Follow run-In, disassembly and assembly instructions for your specific clutch.

Clutches With 4 Adjusting Nuts

Clutch Run-In

Refer to Figure 4-2(View - A):

1.Using a pencil or other marker, scribe a line across the exposed edges of the clutch plates and friction disks.

2.Tighten all 4 nuts uniformly until spring load is low enough that the clutch slips freely with PTO engaged.

3.Start tractor and engage PTO for 2-3 seconds to permit slippage of clutch surfaces. Disengage PTO, then re-engage a second time for 2-3 seconds. Disengage PTO, shut off tractor and remove key. Wait for all components to stop before dismounting from tractor.

4.Inspect clutch and ensure that the scribed markings made on the clutch plates have changed position. Slippage has not occurred if any two marks on the friction disk and plate are still aligned. A clutch that has not slipped must be disassembled to separate the friction disk plates. See Clutch Disassembly & Assembly on page 15.

Refer to Figure 4-2(View - B):

5.Turn all 4 nuts fully back if no two marks on the friction disk and plate are still aligned. Clutch is ready for use.

6.The clutch should be checked during first hour of cutting and periodically each week. An additional set of scribe marks can be added to check for slippage.
