PTO Preset Mode Function Chart
PTO - Variable Mode
The PTO speed control mode is used for both stationary and mobile applications. This mode allows PTO to be controlled in a fashion similar to cruise
control. The operator is able to hold an engine RPM between 800 and 2200 with the SET switch on the cruise stock or the PTO switch. The operator
can "tap up" to increase engine speed in 100 RPM increments with the RESUME switch. The operator may also "tap down" to decrease engine speed
with either SET switch on the cruise control multifunction switch or the PTO switch. Vehicles not equipped with cruise control will not have the "tap
up" capability.
