SECTION 2 - OPERATION
2-70
POWER TAKE-OFF (PTO) - INDEPENDENT
INTRODUCTION
The independent power take-off (PTO) transfers
engine power directly to mounted or trailed
equipment. “Independent” means that the PTO may
be engaged, operated and disengaged with the
tractor stopped or while moving.
The PTO is electrically activated and has automatic
PTO clutch feathering for smooth engagement and
braking.
NOTE: The PTO will automatically disengage when
the engine is stopped.
Model 2145 tractors have two speed PTO capability.
For 540 RPM operation, a 6-spline 34.9 mm (1.375″)
shaft is supplied. A 21-spline 34.9 mm (1.375″) shaft
is supplied for 1000 RPM operation.
The 6-spline shaft is used to operate equipment
having a power requirement up to 65 HP. Equipment
having a higher power requirement should be
coupled to the 21-spline shaft.
Model 2160, 2180, and 2210 tractors have a 1000
RPM PTO. A 21-spline shaft is supplied with the
model 2160 tractor and a 20-spline shaft is supplied
with the 2180 and 2210 tractors. The 21-spline shaft
has a diameter of 34.9 mm (1.375″) while the
20-spline shaft is 44.5 mm (1.75″) in diameter.
Alternative 20 or 21-spline shafts may be purchased
from your dealer. See Option Equipment Section
found at the rear of this manual.
PTO MASTER SHIELD
The PTO master shield, 1, is adjustable to three
positions by placing the prop rod, 2, in positions A, B
or C.
Position A - Shield is level. Use this position during
normal PTO operation.
Position B - Shield is tilted upward. Only use this
position while attaching implement PTO shaft to the
tractor. Lower the shield to position A after the shaft
is attached.
Position C - Shield is tilted downward. Use this
position to provide clearance for the top link when
non-PTO implements are attached.
WARNING
Never stand on the PTO master shield during
PTO operation or anytime. A PTO shaft cover, 3,
is provided and should be installed whenever the
tractor PTO is not is use. The PTO shaft cover is
screw on, screw off.
