Section 4: Maintenance and Lubrication

General Maintenance

Proper servicing and adjustment is the key to long life of any implement. With careful and systematic inspection, you can avoid costly maintenance, time and repair.

!DANGER

Before servicing this implement, turn off tractor engine, remove ignition key and disconnect PTO driveline.

Each new mower should be checked after the first 10 hours of work. All screws and bolt torques should be routinely checked.

At beginning of season:

6.Check and/or change oil; lubricate or grease all points. See Lubrication in this section.

7.Check blade wear and condition of their fasteners, see “Servicing Blades”, page 21.

8.Check wear on guards and curtain.

9.Inspect belts, see “Belt Tension Adjustment”, page 20.

10.Check all screws and bolts to be sure they are tight.

Servicing Blades

Cutting quality as well as safe operation depend on regular inspection and care given to the knives.

!WARNING

To avoid personal injury when blades and/or carrier are being serviced, always block mower up to prevent it from falling.

Check blades for cracks and wear and blade bolts for tightness daily. Blades should be replaced when they are worn excessively, bent, nicked, deformed, or out of balance.

Blades are sharpened on both edges so that they may be turned over to extend their cutting life. Always turn over both blades on a cutterplate at the same time.

NOTE: Blade bolts should be tightened to 55 ft-lb torque.

NOTE: Always replace damaged blades. Never straighten a bent blade. Never replace one knife only per disc. Always replace both of them to avoid creating an out-of-balance force.

!CAUTION

Replace with Land Pride blades only. Substitute blades may not meet specifications and may fail in a hazardous manner that could cause injury.

!CAUTION

When changing blades, always replace blade bolt & blade nut together at the same time. Worn or damaged blade bolts or nuts could fail in a hazardous manner that could cause injury.

Blade Replacement

Refer to Figure 4-1:

NOTE: Always replace blades on cutterplates in pairs.

1.New blades are 1.85” wide. Blades should be replaced when they are worn to about 1 5/16” (B) wide at a distance of 3/8” from the disc. Length (A) of the blade should be greater than 2 1/2”.

2.Replace blades if hole for securing bolt has become oval by 3/32” more than diameter of original hole.

Blade Fastener Replacement

NOTE: Always replace blade bolts and nuts when they have been removed 5 times.

3.Replace bolts when flat sides at bolt flanges are excessively worn or missing altogether.

Refer to Figure 4-2:

4.Replace bolts when diameter (D) of bolt shoulder is less than 5/8”.

5.Replace nuts when height (H) of nut is less than half of original height of 3/8”.
