Adjusting drawbar to tractor’s towing coupler
To allow pick-up to work perfectly, the height (M) of coupled trailer must be correctly set (pick-
up pivoting area).
height
(M) = 4 cm
Note:
Where the floor is uneven, reduce the measurement by 1 cm (M = 42 cm).
- Park unloaded trailer on even ground and
on jockey wheel.
- Attach trailer coupler (A) to tractor so that
on towed vehicle adequate distance exists
between drive shaft and drawbar.
- Set height (M) from ground to centre of feeler
coupling point by adjusting jockey wheel.
Drawbar adjustment when equipped with adjusting spindle:
- Loosen lock-nuts (K).
- Twist turnbuckle barrel (V) correspondingly.
- Check height (M) of trailer coupled to tractor.
Observe following when equipped with hydraulic cylinder:
- Couple trailer to tractor.
- The hydraulic cylinder piston must be completely inserted.
- Twist nut (51) until clamp frame (52) is at
rightangles (about 90°) to slip rod (G). The clamp
can then be raised.
A slot is located in the fork of the regulating
spindle.
- The fastening bolt (56) must make contact with
the inside of the slot.
- Loosen lock-nut (K) on the threaded spindle.
- By twisting the cylinder piston (50), screw the threaded
spindle in or out until the height (M) is achieved.
Slip rod (G) must be able to move in the casing during
the adjustment process (adjust with nut 51).
- Retighten lock-nut (K).
- Twist nut (51) until clamp frame (52) is at rightangles
(90°) to slip rod (G).
Pivoting drawbar safety device check
Function of the automatic clamping device:
It prevents the trailer from tipping up during the return trip.
- Adjust by twisting the nut (51) until the clamp frame (52) prevents the trailer from tipping up
through a slight inclination of the slip rod (G).
Maintenance:
Grease pivoting drawbar safety device frequently!
