SEASONAL CLUTCH MAINTENANCE
It is important that the clutches 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/frozen together. Before using the cutter use the following procedure to make sure the clutch will slip and give the overload protection required.
1.Loosen nuts (Figure 24) on springs until the springs can freely rotate, yet remain secure on bolts.
2.Attach cutter to tractor and start the tractor. Set the engine speed at 1200 RPM.
3.Mark outer plates as shown in Figure 24.
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

HYDRAULIC HOSES
FIGURE 24
Replace pinched and broken Hydraulic Hoses at once. Tighten any Hydraulic Fitting with fluid leaking from it. If fluid still leaks, loosen the fitting, apply a pipe thread compound to the threads and tighten. Care must be exercised when tightening Hydraulic Fittings. Too much tightening can cause the fittings to crack and require replacement fittings.
Although a small amount of oil will be present from bleeding at all Hydraulic Fittings, significant amounts of oil leaking around the Breather Plug on the Cylinder indicates that the seal in the Cylinder is worn out. Replace the seals in the Cylinder immediately before the Cylinder is damaged or too much hydraulic fluid is lost.
SKID SHOES
Skid shoes are made of carbon steel to reduce wear and increase service life. Premature wear can be caused by the mower Center or Wing sections being set too low which allows the Wing Skid Shoes to drag on the ground. Dragging the Skid Shoes on the ground or running the Skid Shoes into solid objects can contribute to early frame failure on the mower. Replace worn Skid Shoes as required.
