OPERATION
Flail Mowers are capable under adverse conditions of throwing
objects for great distances (300 feet or more) and causing serious
injury or death. Follow safety messages carefully.
STOP MOWING IF PASSERSBY ARE WITHIN 300 FEET UNLESS:
-Front and Rear Deflectors, Chain Guards, or Bands are installed and in good, workable
condition;
-Mower sections or Wings are running close to and parallel to the ground without
exposed Blades;
-All areas have been thoroughly inspected and all foreign material such as rocks, cans,
glass, and general debris has been removed.
NOTE: Where there are grass and weeds high enough to hide debris that could be
struck by the blades, the area should be: inspected and large debris removed, mowed at
an intermediate height, inspected closely with any remaining debris being removed, and
mowed again at desired final height. (This will also reduce power required to mow,
reduce wear and tear on the Mower drivetrain, spread cut material better, eliminate
streaking, and make the final cut more uniform.)

12.3 PTO RPM and Ground Speed
Ground speed for mowing will depend upon the height, type, and density of vegetation to be cut.
Recommended speed for efficient mower performance is between 2 and 5 mph(3-8 kph). Operate the mower
at its full rated PTO speed to maintain blade speed for a clean cut. Refer to the tractor operator’s manual or
the tractor instrument panel for the engine speed and gear to provide the required PTO and desired ground
speed. Make sure that the mower is operating at its full rated speed before entering the vegetation to be cut.
If it becomes necessary to temporarily regulate engine speed, increase or decrease the throttle gradually.
Ground speed is achieved by transmission gear selection and not by the engine operating speed. The
operator may be required to experiment with several gear range combinations to determine the best gear and
range which provides the most ideal performance from the mower and most efficient tractor operation. As the
severity of cutting conditions increase, the ground speed should be decreased by selecting a lower gear to
maintain the proper operating PTO speed. OPS-R-0025
Do not exceed the rated PTO speed for the Implement. Excessive PTO speeds can cause
Implement driveline or blade failures resulting in serious injury or death.
(SG-26)
Mow at the speed that you can safely operate and control the tractor and mower. The
correct mowing speed depends on terrain condition and grass type, density, and height of
cut. Normal ground speed range is from 2 to 5 mph(3-8 kph). Use slow mowing speeds
when operating on or near steep slopes, ditches, drop-offs, overhead obstructions, power
lines, or when debris and foreign objects are to be avoided.
