Power Take Off
There are two basic types of PTOs avail-
able: engine mounted and transmission
mounted. The transmission mounted PTO is
clutch dependent, which means that opera-
tion can be regulated by depressing or
releasing the clutch pedal. This type of
PTO should not be in use while driving.
The engine mounted PTO is direct-mounted
to the engine and is engaged with a bypass
valve operated by the switch. This type of
PTO can be in use while driving.
NOTE! If your vehicle is equipped with
Autoshift and a Detroit Diesel engine, the
PTO telltale may blink when Autoshift is
on and the transmission shifts gears.
Transmission Mounted PTO
The vehicle should be stopped before en-
gaging power take off. Engage the PTO by
depressing the clutch pedal and pressing in
the bottom part of the switch. Release the
clutch pedal to start the PTO.
One or two PTOs can be run at the same
W3001994
time. Applications change depending on
customer needs and components.
