OPERATION
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.
(SGM-07)
Rotary 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 100 YARDS UNLESS:
Front and Rear Deflectors are installed and in good, working condition;
Mower Head is running close to and parallel to the ground without exposed Blades;
Passersby are outside the existing thrown-object zone;
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.

10.4 Operating Speed and Ground Speed
Ground speed for mowing will depend upon the height, type, and density of vegetation to be cut. Do Not
exceed 2 MPH while operating. 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 operating and desired ground speed. Make sure that the mower is operating at its full
rated speed before entering the vegetation to be cut. Always start and stop cutting blades with engine near
idle.
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 implement 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-B- 0009
