2.3 Tractor Horsepower
The horsepower required to operate the mower depends on many factors including the vegetation to be cut,
terrain condition, operator experience, and condition of the mower and tractor. For most mowing condition, the
RC12 requires a tractor with at least 90 HP. Operating the mower with a tractor that does have adequate power
may damage the tractor engine.
2.4 3-Point Hitch
Lift Type RC Flails should be coupled with a quick hitch only. Direct coupling to tractor 3 point will result in
driveline failure. Sufficient weights should be added to front of tractor to maintain steerage weight on front tires
when flail is raised (20% of tractor weight should be on front tires). Never stand between flail and tractor when
coupling with quick hitch. Remove or adjust drawbar to provide clearance for driveline on lift type units. Adjust
top link so machine does not tilt back when raised, increasing angles of u-joints which may cause premature
failure.
2.6 Front End Weight
Maintain a minimum of 20% total tractor weight on the tractor front end at all times. Front end weight is critical
to maintain steering ability and to prevent the front end from rearing up. Consult your authorized tractor dealer
for front weights and carriers.
2.7 Power Take Off (PTO)
Only operate the mower on a tractor equipped to operate at 540 rpm PTO speed. Tractors operating at 540
rpm will have a 1-3/8” diameter 6-spline PTO shaft stub. Refer to the tractor operator’s manual for operating
the PTO at the proper speed.
2.5 Drawbar-Pull Type Mower
For equipment operating at 540 RPM, the tractor
drawbar must be positioned at a 14” distance from the
hitch point to the PTO shaft end for proper operation
and minimal wear to the driveline. OPS-R- 0061_D
