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 is the key to the long life of any farm 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

Refer to Figure 4-1:

TIne Replacement

Figure 4-1

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.

6.Remove 2 cap screws and fasteners from tine to be replaced. Remove tine.

7.Install new tine on side of attaching flange as shown.

8.Replace 2 cap screws and fasteners and tighten nuts to proper torque. See The Torque Values Chart in the “Appendix” section on page 27.

IMPORTANT: Replace tines with genuine Land Pride tines only.

!WARNING

Worn tines may be very sharp!

Driveline Protection

Tiller drive components are protected from shock loads by either a two plate friction clutch or a shear bolt. Avoid shear bolt failure by engaging the PTO slowly at low engine rpm. See your Land Pride Dealer when replacing shear bolts. Torque shear bolt nuts to 7-9 ft. lbs.

Shear Bolt and Lock Nut Part Numbers

Part No.	Part Description
RTA10
802-267C	M6 x 35 GR 8.8
803-154C	M6 Lock Nut (Torque nut to 7-9 ft. lbs.)
RTA15
802-115C	5/16”-18	GR 5 bolt.
803-011C	5/16”-18	Lock Nut (Torque nut to 7-9 ft. lbs.)

Friction clutches should be “run-in” prior to initial operation and after long periods of inactivity. You may have one of two types of friction clutches. Refer to Figure 4-2 and Figure 4-3 page 18 to determine which friction clutch your Rotary Tiller has. Follow “Clutch Run-In” instructions for your particular tiller.

To prevent driveline and gearbox damage, repeat “Run-In” instructions at the beginning of each season and when moisture and/or condensation seizes the inner friction plates.

Clutch Run-In

Clutches With 8-Hex Head Socket Bolts

Refer to Figure 4-2 on page 18

1.Loosen counterclockwise all 8 hex head socket bolts uniformly 6 full turns.

2.Cycle clutch on and off 5 or 6 times (15 seconds on and 15 seconds off) with the engine operating at half throttle. Disengage driveline, shut off tractor and remove key. Wait for all components to stop before dismounting from tractor.

3.Tighten hex head socket bolts fully back. Clutch is ready for use

4.The clutch should be checked during the first hour of cutting and periodically each week.

Clutches With 4-Tightening Nuts

Refer to Figure 4-3 on page 18 (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 the spring load is low enough that the clutch slips freely with the PTO engaged.

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