MAINTENANCE

It is important that the clutch lining plates slip when an obstacle or load heavier than the clutch setting is

encountered. Therefor e, if the mach ine sits out side lon ger than 30 days and is e xposed to rain and/o r humid air

it is important to make sure that the clutch lining plates are not rusted/corroded together. Before using the

mower use the following procedure to make sure the clutch will slip and give the overload protection required.

1. Loosen nuts (Figure Mnt-FL-0003) on springs until the springs can freely rotate, yet remain secure on

bolts.

2. Attach mower to tractor and start the tractor. Set the engine speed at 1200 RPM.

3. Mark outer plates as shown in Figure Mnt-FL- 0003.

4. Engage the PTO (approximately one second) and then quickly disengage it. The friction lining plates

should break loose (check the mark).

5. Turn tractor off and tighten the nuts on the springs to their original position of 1-3/16” compressed spring

length.

General

Mowing is accomplished b y a series of knives which rotate at high speed on a sha ft. The ro tor shaf t is driven by

an extension shaft, from the gearbox, through a drive belt. Belt tension is maintained by a spring-loaded idler

pulley.

The cutter unit is raised and lowered by using the tracto r’s three-point lift.

The cutter unit rides on a large roller assembly. The position of this roller is adjustable and will determine the

cutting height of the knives.
