Coupling
This chapter explains how to couple the plough to the tractor.
Safety
Risk of injury when coupling
There is an increased risk of injury when the plough is coupled to the
tractor. Therefore:
•
Secure the tractor to prevent it from rolling. Apply the handbrake.
•
Do not stand between the tractor and plough when coupling
•
Lift and lower the plough slowly
Check the length of the hose
Check the length of the hose between the plough and tractor for suffi
-
cient slack. If the hoses are taut or stretched, the hoses may be dam
-
aged or pulled out.
Coupling
To couple the plough to the tractor
> Connect the draw arms of the tractor to the cross shaft on the
plough
> Connect the top linkage pin on the tractor to the plough's turning
head/tower
> Connect the hydraulic hoses to the tractor.
> Carefully lift the plough.
> Fold up the parking stand
> Check the linkage geometry (see below)
> Turn the plough to check the clearance from the ground and from
the tractor (see below)

Top linkage coupling
•
Use the slotted holes on 4-share ploughs or larger. This allows the
plough to follow field contours
•
Use the fixed holes on 2 and 3-share ploughs. This prevents the
plough from tilting up in heavy or stony soils.
•
Make sure the top linkage inclines slightly towards the tractor from
the plough.
