MAINTENANCE
REVERSING MOWER ROTATION REAR
MECHANICAL DRIVEN FLAIL MOWERS
Remove the rear shaft guard and disconnect the chain coupling to the shaft.
Disconnect the P.T.O. drive shaft from the right angle gear box. Remove the gear box
from the flail frame and lay down flat so that gear oil does not leak out.
Switch the top breather vent plug with the drain plug on the bottom. Remove the
input shaft guard. The input shaft must be pressed through or turned around so the
rear extension is equal to what the original front dimension was. Turn the gear box
180° and install on the flail frame so the chain coupling sprockets are side be side and
the breather vent plug is on the top of the case.
The sprockets must be aligned and spaced approximately 3/8” apart. When
changing from standard cut to smooth cut rotation, a spacer plate may have to be
installed between the gear box and the frame. When changing from smooth cut to
standard cut rotation the spacer plate is to be omitted. Install the chain for the chain
coupling. If there is any binding, or no free movement in the chain, the bearing next to
the coupler may be shimmed as required to eliminate the chain binding.
Change all the knives on the cutter shaft as required. The cutter shaft rotates in
the same direction as the tractor tires when going forward for standard knives. The
cutter shaft rotates opposite the tractor tires for smooth cut knives.
