Sharpening Blades

NOTICE

■When sharpening blades, grind the same amount on each blade to maintain balance. Replace blades in pairs. Unbalanced blades will cause excessive vibration, which can damage gearbox bearings. Vibration may also cause struc- tural cracks to cutter.

1.Sharpen both blades at the same time to maintain balance. Follow original sharpening pattern.

2.Do not sharpen blade to a razor edge—leave at least a 1/16" blunt edge.

3.Do not sharpen back side of blade.

CAUTION

Your dealer can supply genuine replacement blades. Substitute blades may not meet original equipment specifications and may be dangerous.

■Crossbar rotation is counterclockwise when looking down on cutter. Be sure to install blade cutting edge to lead in counterclockwise rotation.

NOTE: Always replace or sharpen both blades at the same time.

1.Inspect blade pin (28) for nicks or gouges, and if you find any replace the pin.

2.Insert blade pin through the blade. Blade should swivel on bolt; if it doesn’t, determine the cause and correct.

3.Align crossbar (43) with blade access hole in cutter frame. Apply a liberal coating of Never-Seez®or equivalent to blade pin and crossbar hole. Make sure blade offset is away from cutter.

4.Insert blade pin (28) through blade. Align key on blade pin with keyway in crossbar and push blade pin through crossbar.

5.Insert lock washer (45) and nut (46) through blade access hole in the cutter frame. Install on blade pin (28) and tighten to 450 lbs-ft.

ADJUSTING SLIP CLUTCH

Comer

1.Turn off tractor engine and remove key.

2.Loosen nuts on springs until the springs can rotate freely, yet remain secure on the bolts.

3.Mark outer plates of slip-disc clutch as shown in Figure 10.

4.Securely attach implement to the tractor and start the tractor.

5.Engage PTO for several seconds then quickly disengage it.

6.Turn tractor off and remove key.

7.The friction lining plates should have "slipped". Check the marks placed on the outer plates of the slip-disc clutch in step 3 to make sure this is the case.

8.If clutch does not slip, check assembly for oil, grease and debris. Clean if necessary.

9.Reassemble clutch and tighten bolts no more than 1/8 of a turn at a time until desired setting of 1.26". See Figure 10.

10.If excessive slippage continues, check lining plates for excessive wear. They are 1/8" thick when new and should be replaced after 1/32" of wear to ensure proper operation.

Walterscheid

The slip clutch is designed to slip so that the gearbox and driveline are protected if the cutter strikes an obstruction.

A new slip clutch or one that has been in storage over the winter may seize. Before operating the cutter, make sure it will slip by performing the following operation:

1.Turn off tractor engine and remove key.

2.Remove driveline from tractor PTO.

3.Loosen six 10 mm cap screws (6) to remove all tension from spring plate (5).
