Ground Speed PTO
When operating in ground speed PTO, the
PTO shaft operates in proportion to ground
speed.
This produces one revolution of the
PTO shaft for approximately each twenty
inches of
forward
travel of the Tractor, re-
gardless
of engaged transmission gear or
speed.
This feature is
very
desirable when
operating
implements
which require operat-
ing speeds proportional to the Tractor for-
ward
speed (i.e. : PTO driven side delivery
rake, etc.)
IMPORTANT: When backing the
Tractor, the PTO shift lever must
be shifted from ' ' Gr o u n d Speed
PTO" to the "Neutral" position.
Failure to do so may result in dam-
age to the implement, as the imple-
ment drive mechanism will be re-
versed.

"Independent" Power Take-Off
(See Fig. 38}
On Tractors equipped with" Independent"
PTO, operation of the PTO shaft is com
-
pletely
independent
of
the
transmission drive
clutch.
Fully
depressing the clutch pedal
does not
stop
the
PTO
shaft, only the ground
travel
of
the Tractor.
"Independent" PTO clutch control is en-
gaged
and
disengaged by a hand lever. There
are two positions provided for the lever,
"ON" and "OFF". A PTO brake is engaged
in the "OFF" position to prevent the PTO
shaft from "creeping" due to oil drag in the
clutch. The PTO clutch may be feathered by
slowly moving the ''Independent'' PTO shaft
lever to the full "ON'' position.
The gradual
build-up of oil pressure
to the clutch pack,
by slow movement of the
PTO shift lever,
provides smoother engagement.
When the
engine is operated at
1700 rpm, the PTO
shaft operates at 540
rpm.
This conforms
to the ASAE standard
PTO speed recom-
mendation.
IMPORTANT: Operate
the "Inde-
pendent'' PTO with the
shift lever in
fully" ON" detent position.
To en-
sure positive engagement
of the
Power Take-Off Clutch,
the engine
must be operated at speeds
above
7 50 rpm.
Do not modulate
or at-
tempt to start a dead load.
Transmission Driven Power Take-Off
On Tractors equipped
with Transmission
Driven Power Take-Off, the
operator may se-
lect only proportional engine
speed PTO.
When the engine is operated
at 1500 rpm the
PTO shaft operates at 540 rpm.
The Tractor is equipped
with a single
stage clutch.
When the clutch
pedal is de-
pressed, the forward motion of
the Tractor,
hydraulic pump and rotation of
the PTO shaft
is stopped.

CAUTION: NEVER
operate
PTO driven implements
without
proper safety shields
installed
on Tractor
and implement.
PRACTICE SAFETY.
Never Operate PTO without
Shields.
