Replace the upper and lower clean-out covers.
Turn the head by hand to be sure it turns freely. If head fails to rotate

When you have finished working be sure there is nothing in the head or
feed roll.
After shutting down the unit rotate the head by hand backwards to
remove any small chips or debris.
9. BLADE REPLACEMENT
The best way to tell if the blades need replacing is to watch the chips
coming out of the discharge. If they are long and stringy, the blades need
to be serviced or replaced. Sometimes blades may feel sharp to the
fingers, but may be worn or rounded. The blades are all reversible.
Dull blades cause many problems, including:
Loss of cutting power
Jamming or Plugging of the discharge chute
Rough cutting with more vibration than usual
Broken feed roll shaft
Wear or Loosening of the main bearing causing the flywheel or
blades to come in contact with the case or bed blade.
Feed roll kicking out of gear
Lack of material feeding
To remove the blades, take the PTO shaft out of gear. Shut off the tractor
and keep the keys in your pocket. The blades are accessed by removing
the inspection plate on the side opposite the chute.
Unhook the feed roller springs, block the feed roll up, and with an Allen
Wrench on the chute side and a socket on the other, and remove the
attachment bolts. If necessary a small screwdriver can be used to clean
