Driving and Operating 9-47
or by pressing and releasing the
remote arming switch. Then within
five seconds, assert the remote
PTO enable switch to on. This
provides an initial start-up engine
speed to match the engagement of
the PTO load. The PTO standby
engine speed can be reprogrammed
to a higher speed by your dealer.
Choose one of two factory presets
by pressing the PTO in-cab
− /SET
or +/RES switch positions or the
remote PTO SET switch.
Speed 1 and Speed 2 are
programmable by a service
technician from base engine idle
rpm to max PTO operation speed
(3100 rpm).
. Speed 1: Pressing the − /SET
position of the PTO switch
results in a preset speed of
1250 rpm.
. Speed 2: Pressing the +/RES
position of the PTO switch
results in a preset speed of
1700 rpm.
Pressing the
9
switch position on
the PTO in-cab switch or moving the
remote PTO enable switch to OFF
results in the return of the engine
speed back to normal idle. The PTO
load relay is also disengaged.
Maximum PTO Operating Speed:
During PTO operation, the
accelerator pedal can be pressed to
adjust the engine speed. To protect
the PTO from over-speed, the PTO
system will disengage when the
engine speed exceeds 2100 rpm.
The Stationary PTO Mode provides
both in-cab and remote controls.
The in-cab controls are enabled as
the factory preset. The remote
controls are disabled. This factory
preset configuration can also be
reprogrammed to enable the remote
controls, and disable the in-cab
PTO controls (i.e., PTO switch,
accelerator pedal). See your dealer
for more information.
Variable PTO Mode
In this mode, the vehicle can be
programmed for stationary or mobile
operation.
The variable PTO mode controls
engine speed and PTO load
engagement is selected by either
the PTO in-cab or remote switches.
Engine speed selection is variable
between base engine idle speed
and a maximum of 3100 rpm
(factory setting 2100 rpm).
In the mobile PTO mode, the
vehicle will operate at a vehicle
speed resulting from the current
PTO engine speed request and
current transmission gear range
selected.
Vehicle speed stability is greatly
improved by shifting into the
transmission manual mode because
upshifts are limited. This reduces
the maximum vehicle speed while
allowing high engine speed
operation. Therefore, low vehicle
