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 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.

Clutches With 8-Hex Head Socket Bolts
Refer to Figure 4-2 on page 20
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 20 (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.
