ADJUSTMENT
The tailwheel is adjustable in one inch increments

assembly from mounting bracket. Stack spacers on
spindle as necessary to achieve desired height.
Large spacers are two inches, small spacers are one
inch.
Slide spindle back into bracket placing remaining
collars on top of spindle. Install retaining pin. Note
that any change in tailwheel height should be fol-
lowed by a 3-point hitch top link adjustment to keep
cutter level.
TAILWHEEL IS NOT TO BE USED TO SUP-
PORT CUTTER AT TRANSPORT SPEEDS.
MAXIMUM SPEED FOR TAILWHEEL IS 6
MPH. EXCEEDING THIS SPEED COULD
CAUSE EQUIPMENT FAILURE WITH

Note that when cutter is equipped with both side-
wheel and tailwheel, the adjustment of one can
affect adjustment of the other. If the cutting height is
higher than 4 inches, cutter must be totally support-
ed by tractor 3-point lift. When cutting a ditch or
bank, sidewheel and tailwheel can be adjusted inde-
pendently as needed.
