PTO BRAKE
To adjust the PTO brake:
1. Remove the attachment and lower the rear of the
tractor to the ground.
2. Carefully clean the front of the transmission.
Remove the quick hitch studs from the
transmission.
3. Remove the quick hitch casting and PTO brake
assembly (Figure 10).
NOTE: The attachment gasket must be replaced if
damaged.
4. Tighten all PTO brake bolts until the springs are
solid. Back all bolts up 1/2 turn (Figure 11).
NOTE: Do not tighten the bolts in a circular sequence,
that is, by tightening the bolt next to one which was just
tightened. The bolts should be tightened in a cross
sequence, that is, by tightening one bolt, then
tightening the bolt which is across from it on the plate.
Continue tightening the bolts in this sequence until all
the bolts are tightened.
Make sure the trunnion block is on the shipper shaft
and held in place by the dog. The dog should rest on
the spiral teeth of the clutch dog plate. Install the
gasket.
Align the splines on the quick hitch shaft with those in
the dog. Slide the quick hitch casting and PTO brake
assembly back into the place on the front of the
transmission. Install the quick hitch studs and tighten.
