Replace the shear
bolt [150 B]
Only fit original shear bolts
Only fit original shear bolts. Failure to use original shear bolts can
damage the plough.
The 150 B is equipped with shear bolts for protection against objects
stuck in the soil.
When a shear bolt shears off:
> Replace it with an original shear bolt
> Tighten all the bolts again (see diagram)
Check the spring
is the correct
length [150 S]
The length of the springs from pin to pin must be 70 cm. This results
in maximum spring tension. Over time, the spring adjustment can
change gradually and needs to be corrected.
> Check the spring length every year.
> Adjust the length if it is shorter or longer than 70 cm.
