Section 5: Maintenance & Lubrication
Maintenance
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 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.
Cutter Blade Maintenance
!DANGER
Always disconnect hydraulic hoses from the Skid Steer before servicing underside of deck. The motor can be engaged if Skid Steer is started resulting in possible damage to the cutter, bodily injury and/or death.
!WARNING
Always secure the cutter deck in the up position with solid supports before servicing the underside. Never work under equipment supported by hydraulics. Hydraulics can drop equipment if controls are actuated or if hydraulic lines burst. Either situation can drop the cutter instantly even when power to the hydraulics is shut off.
IMPORTANT: Replacement blades should be ordered in pairs. Order only genuine Land Pride blades. Other blades may not meet specifications.
Always inspect cutting blades before each use. Make certain they are properly installed and are in good working condition. Replace any blade that is damaged, worn, bent, or excessively nicked. Small nicks can be ground out when sharpening.
Remove cutting blades and sharpen or replace as follows:
1.Align blade bolt with access hole in deck.
2.Place skid steer in park and/or set brakes, shut engine off and remove ignition key.
3.Always disconnect hydraulics from Skid Steer and secure cutter deck in the up position with solid supports before servicing underside of cutter.
4.See Figure
5.Both blades should be sharpened at the same angle as the original cutting edge and must be replaced or
a.Do not remove more material than necessary.
b.Do not heat and pound out a cutting edge.
c.Do not grind blades to a razor edge. Leave a blunt cutting edge approximately 1/16” thick.
d.Always grind the cutting edge so that the end of the blade remains square to the cutting edge and not rounded.
e.Do not sharpen the back side of the blade.
f.Both blades should weigh the same after sharpening with not more than 1 1/2 oz. difference. Unbalanced blades will cause excessive vibration which can damage gearbox bearings and create structural cracks.
6.Carefully check cutting edges of blades in relation to blade carrier rotation to ensure correct blade placement. Cutter blades must be installed with cutting edge leading in rotation and airfoil (lift) must be oriented towards the top of the deck.
Refer to Figure
IMPORTANT: Shim (#2) below may or may not be required. If blade deflection is less than 3/4" without a shim, then the shim is not used. However, a shim is required if blade deflection is greater than 3/4".
IMPORTANT: Locknuts can loose their ability to lock properly once removed. Therefore, always use a used blade nut or plain nut in steps 7 & 8 below and then replace used nut with new locknut in step 9.
7.Start by assembling blades without shim (#2). Insert blade bolt (#1) through blade (#3), dish pan (#4) and flat washer (#5). Temporarily secure blade with a used 1

8.Check blade deflection. If deflection is greater than 3/4", remove blade bolt and reassemble as before except include shim (#2) when reassembling. Select shim thickness based on deflection. The greater the deflection, the thicker the shim.
9.Once blade deflection is correct,replace used nut with new locknut (#6) and torque to 450 ft. lbs.
10.If replacing dishpan (#4), nut on gearbox output shaft should be torqued to 450
