POWER TAKE-OFF {See Fig. 36)
A power take-off shaft provides engine
power directly to PTO operated implements,

or can be equipped with a belt-pulley assem-
bly (Accessory) to belt-driven equipment.
The splined PTO shaft diameter is
1-3/8" (ASAE std.). The annular groove in
the shaft allows fast connection of push-but-
ton PTO couplers.
NOTE: A screw-on type cover pro-
tects the shaft when it is not in use.

"Live" Power Take-Off (See Fig. 37)
On Tractors equipped with "Live" PTO,
the operator may select two PTO speeds:
( 1) Proportional engine speed PTO or, (2)
Proportional ground speed PTO. Selection of
these two speeds is done with the PTO shift
lever.
Engine Speed PTO
Your MF 135 Tractor is fitted with a
dual clutch, which allows the PTO shaft to
operate independent of Tractor forward mo-
tion. When operating in engine PTO, the
primary clutch may be disengaged, stopping
Tractor forward motion; the PTO shaft will
continue to rotate. Fully depressing the
clutch pedal through the second stage will
stop PTO shaft operation as well as the hy-
draulic pump. When the engine is operated
at 1700 rpm, the PTO shaft operates at 540
rpm. This conforms to the ASAE standard
PTO speed recommendation.
