3. Control & Operation of the PTO, 3-Point Hitch, and Rear Hydraulic System
Introduction
The PTO (Power Take-Off) is a rotating connection at the rear of the tractor tied into to the tractor engine. The
PTO is used to power attachments to the tractor. Generally attachments which use the PTO are also attached to
the back of the tractor through the 3-Point Hitch. The 3-Point Hitch provides a physical link of the attachment
to the tractor, but also allows the hitch (and thereby the attachment) to be raised or lowered using power from
the hydraulic system. First will be a description of the PTO, second will be the description of the 3-Point Hitch
and hydraulic system controls, and finally will be a generic description of how to connect and operate a mower.
PTO (Power Take-Off)
The PTO can be engaged and disengaged by using the PTO Control Lever on the right side of the transmission
box next to the Auxiliary Gear Shift Lever (see pictures earlier in the Manual) and the PTO Speed Control Lever
located at the rear of the tractor.
In order to connect the attachment to the PTO, put the tractor and the attachment into alignment. Put the PTO
Control Lever in the “DIS” position and put the tractor in Neutral gear. Either turn off the tractor (or put the
tractor into neutral) and set the Parking Brake. Make sure the PTO Control Lever is in the DIS position and that
the PTO is not turning. With the PTO not
spinning, couple the desired attachment to the PTO shaft using the
locking collar to make sure the connection is firm.
If the attachment also needs to be connected to the 3-Point Hitch (see below), make this connection at the same
time (see instructions which come with the attachment). The 3-Point Hitch may need to be raised or lowered to
make this connection easier (see below).
Set the PTO Speed Control Lever to either 540 RPM or
1000 RPM based on the attachment being used
(remember 540 RPM is the most commonly used
speed). (When disconnecting the PTO from an
attachment remember to disengage the Speed Control
by putting the PTO Speed Control Lever in the middle
neutral position.)
When the attachment is completely connected, you
should give it a visual test with the tractor running to
assure proper connections. Start the tractor, put it in
Neutral gear, and Engage the PTO. When engaging or
disengaging the PTO push the Clutch pedal all the way
down. To engage the PTO, move the control lever from
DIS (Disengaged) to EN (Engaged). Assuming the
PTO seems to be working correctly Disengage it, get
off the tractor, and recheck the connections one more time.
