POWER TAKE-OFF (PTO) OPERATION
WARNING
To reduce the possibility of personal injury,
comply with the following guidelines before
attaching or detaching PTO equipment, and
before working on or clearing PTO
equipment.
1. Attaching the PTO
• Stop the engine.
• Set the parking brake.
• Disengage the PTO using the PTO speed
selector lever is “NEUTRAL” position.
• Remove the PTO cap.
• Wait until the PTO shaft stops turning.
• Attach the mounted or drawn equipment.
1. Ensure that the equipment-driven shaft is
properly aligned and locked to the tractor
PTO drive shaft, and that the PTO shield is
lowered into the guarded position.
2. With the PTO disengaged, start the engine.
For mounted equipment, raise and lower the
equipment to ensure there are proper
clearances for operation.
3. With the transmission range lever still in
neutral (N), move the PTO speed selector to
the desired position.
IMPORTANT: The PTO may be damaged if the
PTO speed selector lever is not fully moved to
the selected positions.
4. Engage the PTO by using the PTO control
switch.
NOTE: The PTO indicator light, located in the
instrument panel, will illuminate when the PTO is
engaged and the key switch is in the “ON”
position.
5. Check the PTO-driven equipment for proper
operation by gradually increasing the engine
RPM with the manual throttle control.
5. If the equipment is operating properly, shift to
the desired operating gear.
6. Control the PTO speed using the throttle.
Never operate in an over speed condition.
PTO speeds relative to engine speeds are
shown in the following tables:
Speed selector
position
PTO Speed
(rpm)
Engine
speed (rpm)
1 540 2475
2 540 1755
2 750 2438
WARNING
Rear PTO speeds in excess of 630 PTO rpm
may damage equipment that is designed for
540rpm operation and could result in
personal injury to the operator or bystanders.
7. When making sharp turns with towed
equipment, or with mounted equipment in the
fully raised position, disengage the PTO
using the PTO control switch.
10. When traveling on highways or for any great
distance, disconnect the PTO-driven shaft at
the tractor PTO shaft.
11. Reinstall the PTO shaft cap whenever
PTO-driven equipment is disconnected from
the tractor, or when the PTO is not being
used.
WARNING
To avoid inadvertent movement of PTO
implement, disengage the PTO after each
use.
PTO OPERATION
(WITHOUT OPERATOR IN SEAT)
To operate the rear PTO without the operator
being in the seat, the following operations must
be performed:
• Transmission shuttle lever and main shift
lever are in “NEUTRAL” position
• Parking brake in "applied" position
IMPORTANT: If the operator leaves the seat
without the shuttle lever in the “NEUTRAL”
position and with the PTO engaged, the engine
will shut off in approximately two seconds.
