Maintenance
Proper servicing and adjustment is the key to the long life of any farm implement. With careful and systematic in- spection, you can avoid costly maintenance, time and re- pair.
After using your Rotary 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
1.Both blades should be sharpened at the same angle as the original cutting edge and must be replaced or reground at the same time to maintain proper balance in the cutting unit.
NOTE: Care should be taken in order not to re- move 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, ex- amine bolts for excessive wear and replace if neces- sary. To replace blades:

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.
Driveline Clutch
Cutter drive components are protected from shock loads by a four 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
!CAUTION!
Engage parking brake, disengage PTO, shut off tractor, and re- move key before making any of the following adjustments.
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
4.Inspect the clutch and ensure that the scribed mark- ings made on the clutch plates have changed position. If any two marks on a friction disk and plate are still aligned, such indicates that slippage has not occurred and the clutch must be disassembled to separate the friction disks, see "Clutch Assembly and Disassem- bly", on page 21.
5.Tighten each of the 8 spring retainer nuts on the clutch housing EXACTLY 2 revolutions to restore the original clutch setting pressure.
6.The clutch should be checked during the first hour of cutting and periodically each week. An additional set of scribe marks can be added to check for slippage. See "Clutch Assembly and Disassembly", on page 21, to adjust for proper spring length.
