OTHER MAINTENANCE AND CLEANING
The spreader’s hydraulic system for operating the belts is tted with an oil lter. The
lter’s replacement interval largely depends on the operating conditions, and the
meticulousness with which the tractor’s hydraulic system is kept clean, but it is advisable
to replace the lter every two to four years.
The oil lter is placed in under the spreader and it is easiest to access it from the
front end of the spreader >.
> Oil filter
The electrical actuators controlling the downshutes are protected by a stainless steel
shield. The shield only protects them against mechanical impacts but does not prevent
fertilizer and dust from getting in. Therefore, remove the shield regularly and clean
around the actuators. This should always be done before washing or prolonged idle
periods. NEVER use water for cleaning if the shield has been removed.
> Actuators
Check that the spreading system is clean and in working order every day. Insucient
cleaning or worn-out spreading booms can result in poor spreading patterns.
Certain types of fertilizer and humid weather can create coatings on downshutes and
spreading vanes, so these should be inspected and cleaned regularly during operation.
Replace the spreading vanes if holes are worn into them. It is very important that
the spreading vanes are correctly mounted on the spreading discs, as
shown in the drawing.
> Spreading system
Always be careful when washing with a high-pressure washer and never spray directly
on bearings, sensors, etc.
Before winter storage, clean the spreader carefully and apply a layer of rust-protective
oil to the implement. Be careful not to apply oil on the rubber belt as this will
dissolve the rubber. It is advisable to rst spread a layer of cat litter or sawdust on
the belt to absorb excess oil. Remember to remove the material aer four or ve days
once all the oil has been absorbed.
