Pto Rpm And Ground Speed; Operating The Mower - RHINO FC-0110 Operator's Manual

10.4 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 str
Do not exceed the rated PTO speed for the Implement. Excessive PTO speeds can cause
Implement driveline or component failures resulting in serious injury or death.
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.

10.5 Operating the Mower

The mower is designed to cut vegetative material up to 2-1/2" in diameter. Travel at a speed that allows the
mower sufficient time to cut through the vegetation and maintain the operating speed at 540 rpm to prevent
overloading the mower and tractor and to produce a clean cut. Choose a driving pattern that provides the
maximum pass length and minimizes turning. Remember, sharp blades produce cleaner cuts and require less
power.
Under certain conditions, tractor tires may roll some grasses down preventing them from being cut at the same
height as the surrounding area. When this occurs, reduce the tractor ground speed while maintaining the
operating speed of the mower. A slower ground speed will permit grasses to at least partially rebound and be
cut. Taking a partial cut and/or reversing the direction of travel may also help produce a cleaner cut
Avoid mowing in the reverse direction when possible. In situations where the mower must be backed to
access areas to be cut, make sure there are no persons or other foreign debris behind the mower before
mowing in reverse. When mowing in reverse, operate the tractor and mower at a much reduced ground speed
to ensure control is maintained of the tractor and cutter.
Do not mow with two machines in the same area except with Cab tractors with the windows
closed.
Mow only in conditions where you have clear visibility in daylight or with adequate artificial
lighting. Never mow in darkness or foggy conditions where you cannot clearly see at least
300 feet (90 m) in front and to the sides of the tractor and mower. Make sure that you can
clearly see and identify passersby, steep slopes, ditches, drop-offs, overhead obstructions,
power lines, debris and foreign objects. If you are unable to clearly see these type of items
discontinue mowing.
