The PTO preset mode is used for stationary applications. PTO will remain engaged while mobile in the preset mode however PTO set and resume speed
controls will be inoperative. Engine RPM will also return to normal. This mode provides a default standby speed of 800 or 850 RPM depending on the
engine and transmission combination. This mode also provides 2 default PTO control speeds: PTO set speed of 1250 RPM and PTO resume speed of
1700 RPM. Please note that the standby speed is not to be used as a PTO control speed. Vehicles not equipped with cruise control will not have the
resume speed capability.

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 stock or the PTO switch. Vehicles not equipped with cruise control will not have the "tap up"
capability.
