14. Possible incidents and solutions
INCIDENTS
CAUSES and SOLUTIONS
1- Check tractor and spreader electric circuit
2- Check hydraulic connection of spreader and tractor
single-acting distributor.
1 – Abnormal functioning of all
hydraulic motors when starting
equipment
3- Too important return pressure.
1- Too much pressure loss with dual-acting
distributor. Connect to single-acting distributor and
free return
2- Check calibration of distributor unit on spreader
and tractor (180 bar)
3- Pollution in tractor’s hydraulic circuit (see tractor
filter)
2 – Lack of hydraulic power
4- Tractor pump failure (flow and pressure)
1- Back pressure on hydraulic return (see hydraulic
connection)
2- Reduce flow to 45 l/min
3 – Damaged hydraulic motor seal
1- Too important flow ; reduce flow to 45 l/min
4 - Brutal movements and/or hydraulic
circuit overheat
1- In case of frost, check the rear door is functioning
before loading equipment.
5 – Rear door stuck because of frost
1- Conveyor speed is too fast: reduce speed
2- Important wear of blades on rotors
6- The safety of the declutchable cam
limiter sets off
3- Foreign matters in manure
1- Too heavy load, reduce it
2- Foreign matter ; check and remove it
3- Check electric circuit
7- Moving floor does not start
4- Check hydraulic pressures on tractor
