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 not.
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 frame so
the chain coupling sprockets are side be side and
the breather vent plug is on the top of the case.
The sprocket 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 not 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.
Remove the belt shield. Then remove the adjusting
nuts, washer and spring from the idler tensioning
rod. Remove the clevis rod and small bushing from the idler arm. Remove the idler arm with the pulley
attached. Remove the idler pulley from the idler arm and install the pulley on the other end of the idler arm.
Reinstall the idler arm in the pivot bracket. For standard cut rotation the pulley is toward the front, for reverse
rotation with smooth knives, the idler pulley is toward the rear. Install the small bushing in the idler arm and
connect the idler tensioning rod.
Tightening the adjusting nuts for the idler arm tensioner as shown previously in the maintenance section. Install
the belt shield, the shaft guard and P.T.O. shaft guards.
When operating the mower in reverse rotation with smooth cut knives, remove the baffle and install the front
shield. When operating the mower in standard rotation with standard cut knives, remove the front shield and
install the baffle.
