9.3 Operating the Attached Mower Heads
DANGER!
There are obvious and hidden potential hazards in the operation of this
Mower. REMEMBER! This machine is often operated in heavy brush
and in heavy weeds. The Blades of this Mower can throw objects if
shields are not properly installed and maintained. Serious injury or
even death may occur unless care is taken to insure the safety of the
operator, bystanders, or passersby in the area. Do not operate this
machine with anyone in the immediate area. Stop mowing if anyone
is within 100 yards of mower. (SGM-2)
9.2 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 speed to maintain blade speed for a clean cut. The
engine should be operated at 1800-1950 RPM for front mounted pumps. 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.
DANGER!
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. (SBM-1)
WARNING!
Mow at the speed that you can safely operate and control the tractor and
mower. Safe mowing speed depends on terrain condition and grass type,
density, and height of cut. Normal ground speed range is from 1/4 to 2
mph. Use slow mowing speeds when operating near steep slopes,
ditches, drop-offs, overhead obstructions, power lines, or when debris and
foreign objects are to be avoided. (SGM-7)
Refer to the Assembly Section of this manual to ensure the head is properly attached to the boom hitch and
hydraulic lines are properly connected.
