4.4 Power take-off (PTO).
Power take-
off shaft is placed in the rear axle housing and it’s end rotates to the right (from rear of
the tractor), diameter 35 mm with 6 splines as per PN-77/R-36101 standard with ring groove for
safety attachment of the driven implement telescopic-articulated shaft.
PTO shaft is covered with the PTO guard (4 - Fig.4.6.2) and secured with a PTO cup (when PTO is
not operated) (5 -Fig.4.6.2)
NOTE:
1. After attaching mounted implement carefully raise and lower it using Position Control
lever. Check clearance and the drive shaft slide range/articulation.
2. When attaching trailed implements ensure the drawbar is correctly set.
3. Check all four wheels when carrying out stationary PTO work.
WARNING:
!
Before operating the tractor with PTO driven implements, familiarize yourself with
the safety precautions given below and strictly observe them:
1. Before connecting, disconnecting, cleaning or adjusting the PTO driven
implements, disengage the PTO drive, stop the engine, remove the key, apply
the hand brake and make sure that the PTO drive line has stopped.
2. Do not operate the PTO driven implements without the master shield fitted.
3. Make certain the implement drive shaft is securely locked on the tractor PTO
shaft before starting the engine.
4. After locking the drive shaft on the tractor PTO shaft, attach the drive shaft guard
safety chains to the master shields.
5. Fit the removable cap when the PTO drive line is not in use.
Operating the PTO
Tractors are fitted with double-disc clutch in which PTO output shaft is actuated with a lever. To
engage PTO output shaft, pull the clutch lever (11 - Fig. 3.2) lock upward and shift the lever forward.
To disengage pull lever backwards.
To select PTO drive move the PTO selector lever (15
– Fig. 3.2). There are three positions:
forward position
– engine speed PTO engaged,
centre position
– neutral,
backward position
– ground speed PTO engaged.
Before shifting the lever to engage position set the PTO clutch lever 11 (Fig 3.2) to disengaged
position.
When shifting the lever to the ground PTO engaged, there is obtained PTO speed depending on
tractor speed.
Independent PTO drive means that the PTO shaft rotates proportionally to engine rotation.
To obtain 540 rpm at the PTO set the engine speed to 1810 rpm
NOTE:
Bring the PTO clutch lever to disengaged position (pulled up) while shifting the PTO
selector lever to engaged or neutral position.
When connecting the drive shaft to the tractor and to the implement, this should be carried out strictly
in accordance with the drive shaft or implement manufacturer operating instructions.
