PTO - VARIABLE MODE
PTO Variable Speed Control Mode can be used for both stationary and mobile applications.
This mode allows PTO to be controlled in a fashion similar to which cruise control controls
vehicle speed. The operator is able to hold an engine RPM (between 800 and 2200) with the
SET switch on the cruise control stalk or the PTO switch. The operator can "tap up" to increase engine speed in 100 rpm increments with the RESUME switch on the cruise contro,
stalk or "tap down" to decrease engine speed with either SET switch (on the cruise control
stalk or the PTO switch). Vehicles not equipped with cruise control will not have the "tap up"
or "tap down" capability.
