General Maintenance

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

!DANGER

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

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

At the beginning of each season

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

2.Check blade wear and condition of their fasteners, see “Servicing Blades”, page 18.

3.Check wear on guards and curtain.

4.Retention belts, see “Belt Tension Adjustment”, page 17.

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

Servicing Blades

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

!WARNING

To avoid personal injury when the blades and/or carrier are being serviced, always block the 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.

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

When changing blades, always replace the 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:

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. The length (A) of the blade should be greater than 2 1/2”.

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

2.Replace bolts when wear on the bolt head reaches the contact area of the blade.

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

Refer to Figure 4-2:

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

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

6.Replace Belleville washers on breakaway if they are flattened.
