CUTTING HEIGHT ADJUSTMENT WITH- OUT CASTERS
Mower cutting height is raised, lowered and maintained using tractor hydraulics and lift chains. Proper lift chain adjustment is essential. The chains must be adjusted so that tractor lift arms are in their highest position before the lift or any part of mower is within 1/4" of con- tacting tractor or mower lift stops. Improper lift chain adjustment could result in damage to lift mechanism or tractor.
Adjustment is accomplished by lowering lift arms and inserting lift chains into keyhole lift lugs. Raise the mower, checking to ensure it does not contact any part of tractor. Take up links, one or two at a time, until the desired height is obtained.
There is a long and short slot in the rear lift lugs. Level mower by using these slots as needed.
