Section 4: Maintenance and Lubrication

Maintenance

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 cutter for several hours, check all bolts to be sure they are tight.

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

Service Cutting Blades

2.Both blades should be sharpened at the same angle as the original cutting edge and must be replaced or re-ground at the same time to maintain proper balance in the cutting unit.

NOTE: Care should be taken in order not to remove any more material than necessary when sharpening blades.

3.Both blades should weigh the same after sharpening.

4.When replacing or sharpening the cutter blades, examine bolts for excessive wear and replace if necessary. To replace blades:

h.Order blade bolt Land Pride part # 802-277C.

i.Torque blade bolt lock nut to 450 ft. pounds. An extended cheater bar may be required to achieve proper torque.

IMPORTANT: Replace blades with genuine Land Pride blades only. Blades must be ordered and replaced in pairs.

If replacing dishpan, nut on gearbox output shaft should be torqued to 450 foot/pounds and cotter pin installed in nut with legs securely bent around nut.

Driveline Protection

!CAUTION

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

Cutter 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.

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 4-1:

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.

Clutch Run-In

Figure 4-1

4.Inspect the 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 to disassemble clutch.

5.Tighten each of the 8 spring retainer nuts on the clutch housing exactly 2 revolutions to restore the clutch to the original setting pressure.

6.The clutch should be checked during the first hour of tilling and periodically each week. An additional set of scribe marks can be added to check for slippage. See Clutch Assembly to adjust for proper spring length.
