			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 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

Figure 4-1

Tine Replacement

Refer to Figure 4-1:

IMPORTANT: Replace tines with genuine Land Pride tines only.

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

Engage parking brake, disengage PTO, shut off tractor, and remove key before making any of the following adjustments.

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 8 ft. lbs.

Shear Bolt and Lock Nut Part Numbers

Part No. Part Description

RTR05

165.000.509 BOLT & NUT M6X40 CL 8.8 (Torque nut to 8 ft. lbs.)

Note: If M6 bolt shears excessively, a 1/4”-20 GR5 bolt & nut may be used. A 1/4” -20 GR8 bolt is not recommended as it may cause damage to profiles, tiller frame and/or components.

Clutch Run-In

Friction clutches should be “run-in” prior to initial operation and after long periods of inactivity. 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.

Refer to Figure 4-2on page 19

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

2.Carefully loosen each of the 8 spring retainer nuts by exactly 2 revolutions. It will be necessary to hold the hex end of the retainer bolt in order to count the exact number of revolutions.

3.Start the tractor and engage the 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.

!WARNING

Worn tines may be very sharp!

7.Remove two 1/2”-20 x 1 1/4” GR5 hex head cap screws (#1), hex nuts (#2) and lockwashers (#3). Remove tine (#4).

8.Attach each new tine to the flange making certain it is mounted so that the cutting edge crosses over the flange and leads in rotation as shown in Figure 4-1.

9.Replace cap screws and fasteners (#1, #2 & #3). Tighten nuts to proper torque. See The Torque Values Chart in the “Appendix” section on page 26.
