Section 5 Maintenance and Lubrication
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 cutter for several hours, check all bolts to be sure they are tight.
Replace any worn, damaged or illegible safety decals by obtaining new decals from your Land Pride Dealer.

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 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, ex- amine bolts for excessive wear and replace if neces- sary. To replace blades:
a.Order blade bolt Land Pride part #
b.Blade shim (#30), must be installed to insure a tight and proper fit between the blade bolt and blade. Too tight a fit may cause blade to not swing back into proper cutting position after striking ob- stacles. Too loose a fit will cause play between blade bolt and blade resulting in excessive wear on blade carrier, blade bolts and blades. Three sizes of shims are available: 16 ga., part no. 312- 075D; 18 ga., part no.
c.Torque blade bolt lock nut to 450 ft. pounds. Use a 3’ long pipe to achieve proper torque.
4.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.
