6.3.10 - Tine Obstacle Reset System
IMPORTANT: Working pressure is between 50 – 70 bars.
WARNING: Escaping hydraulic oil can cause serious and potentially deadly injuries.
Hydraulic hoses should only be connected or disconnected when depressurised.
Connections should be correctly positioned to reduce risk
The tine is protected against infield obstacles or excessive forces by an automatic hydraulic reset
system. This is a closed, self-contained circuit.
The working pressure can be adjusted depending on the following factors:
•
Ground conditions
•
Tine depth
•
Forward speed
When the system activates against an obstacle, the oil in the hydraulic cylinder (2) retracts by
overcoming the pressure set in the circuit. As the tine (3) pivots backwards the displaced oil is
contained by the accumulator (1). The system pressure is now higher than the pre-set value.
Once the obstacle has cleared, the tine (3) moves back to the working position by means of the
stored pressure oil in the accumulator (1). The working pressures returns to the original setting.
6.3.11 - Adjusting Tine Obstacle Reset System
Increase Pressure:
1.
Lower the SPX to the ground.
2.
Open manual valve (1)
3.
Operate the tractor spool to increase system pressure as measured on the gauge (2)
4.
Close the manual valve once the desired pressure has been established.
