Modern Predator - PTO RPM and Ground Speed

50 20’ Predator
PTO RPM and Ground Speed
Ground speed for mowing will depend upon the height, type, and density of vegetation to be cut.

throttle gradually.
Ground speed is achieved by transmission gear selection and not by the engine operating speed. The

operation. As the severity of cutting conditions increase, the ground speed should be decreased by se-
lecting a lower gear to maintain the proper operating PTO speed.
Do not exceed the rated PTO speed for the Implement. Excessive PTO speeds can cause mplement driv-
eline or blade failures resulting in serious injury or death.
Mow at the speed that you can safely operate and control the tractor and cutter. 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)
Operating the Cutter
Only operate the cutter from the tractor operator’s seat with the seatbelt securely fastened. The tractor

and maintain the PTO operating speed to prevent overloading the cutter and tractor. Choose a driving
pattern that provides the maximum pass length and minimizes turning.
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 main-
taining the operating speed of the cutter. A slower ground speed will permit grasses to at least partially
