2.2 Shearbolt Protection.
Only one shearbolt is fitted to the spreader. This is located on the spreader end of the
PTO shaft. The bolt is M10 x 60 grade 6.8 mild steel.
ON NO ACCOUNT MUST A BOLT OF HIGHER GRADE THAN 6.8 TENSILE STRENGTH BE
FITTED.
2.3
Pressure relief valve to floor drive.
This valve is cross line type and fitted to the hydraulic motor on the floor drive gearbox.
The pressure can be varied to suit the material being spread. To adjust, engage the oil
flow via the spool valve on the tractor, slacken the locknut and insert an allen key and
turn clockwise to increase pressure until the floor starts to move. Tighten the locknut.
To decrease the pressure, reverse procedure. When making this adjustment, the
spreader pressure will be set lower than the tractor PRV. A diagram in the floor drive
section of this manual shows which screw relieves forward motion and which screw for
reverse motion of the floor.
It is recommended to apply waste oil to the floor chains periodically when spreading dry
material and particularly at the end of the spreading season. This assists in the smooth
running of the machine and prolongs the working life of the components.
