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.

Reinstall the belts and idler tensioning rod. Tighten and lock the tensioning rod as
shown previously in the maintenance section. Reinstall the belt shield.
With the motor rotation changed, now all of he knives on the cutter shaft must
be changed as required. The cutter shaft rotates in the same direction as the
tractor tires when going forward for standard cut knives. The shaft rotates
opposite to standard rotation for smooth cut knives. Smooth cut knives should be
installed so the cutting edge is forward.
When operating in standard rotation, the front shield must be removed and the
baffle installed. When operating in reverse rotation, remove the baffle and install
the front shield. Finally, reposition the wear pads on the hoses and replace the zip
ties as needed to prevent the hydraulic hoses from rubbing or chafing.
