Land Pride RCR16 Series manual Maintenance, Driveline Clutch Optional, Service Cutting Blades

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.

Driveline Clutch (Optional)

Cutter drive components are protected from shock loads by a two plate slip-clutch. The clutch must be capable of slippage during operation to protect the gearbox, driveline and other drivetrain parts.

Prior to initial operation and after long periods of inactivity, the clutch should be "run-in" to remove any oxidation that may have accumulated on the friction surfaces.

Service Cutting Blades

1.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.

2.Both blades should weigh the same after sharpening.

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

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

b.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.

Shearbolt Driveline

Shear Bolt Replacement

The Standard Shear Bolt Driveline is secured to the cutter with a shearbolt for protection of the driveline and gearbox. The shearbolt is designed to shear off when the blade impacts objects that the cutter is not designed to cut through. Should the shearbolt need replaced, replace with Land Pride part #802-264C. Refer to page 9 Figure 1-2.

IMPORTANT: A snap ring (Land Pride part #800-079C) is installed so that driveline does not come loose from the gearbox should the shearbolt shear.

!CAUTION

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

Clutch Run-In

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 discs.

2.Carefully loosen each of the 8 spring retainer nuts on the clutch housing a total of 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 PTO drive for 2-3 seconds to permit slippage of the clutch surfaces. Disengage the PTO, then re-engage a second time for 2-3 seconds. Disengage the PTO, shut off tractor and remove key. Wait for all components to stop before dismounting from tractor.

4.Inspect the clutch and ensure that the scribed markings made on the clutch plates have changed position. If any two marks on a friction disc and plate are still aligned, this indicates that slippage has not
