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 2 to 5 mph. 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-7)
10.4 PTO RPM and Ground Speed
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.
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. 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.
WARNING!
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)
Before engaging the PTO, make certain that the area is clear of bystanders and passersby. The mower wings
must be completely lowered and the deck positioned at a safe mowing height. NEVER engage the PTO with the
mower wings in the raised position.
Do not let the Blades turn when the Mower deck is raised for any
reason, including clearance or for turning. Raising the Mower deck
exposes the cutting blades which creates a potentially serious hazard
and could cause serious injury or even death from objects thrown
from the blades. (SRM-7)
DANGER!
10.3 Engaging the Power Take Off (PTO)
Do not put hands or feet under Mower decks. Blade contact can result
in serious injury or even death. (SGM-9)
DANGER!
Set the tractor engine speed at approximately 1,000 RPM before engaging the PTO. Shift the PTO control to the
on position, and slowly increase the engine speed until the PTO is operating at the rated speed. If you hear
unusual noises or see or feel abnormal vibrations, disengage the PTO immediately. Inspect the mower and Flex-
Arm to determine the cause of the noise or vibration and repair the abnormality.
