MAINTENANCE

MAINTENANCE	It is important that the clutch lining plates slip when an obstacle or load heavier than the clutch setting is
	encountered. Therefore, if the machine sits outside longer than 30 days and is exposed to rain and/or 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 (Image 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 Image 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 by a series of knives which rotate at high speed on a shaft. The rotor shaft 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 tractor’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.
