7.2.6 Hydraulic Coulter adjustment
The hydraulic coulters run using a constant oil supply from the tractor. The pressure in the system is
regulated using a pressure relief valve located at the front of the drill near the storage locker. The pressure
gauge fitted to the valve displays the working pressure. About 10 L/min (or approx. 20%) of oil will be
required to allow the coulters to respond to changing ground conditions. If coulters don’t respond fast
enough increase the oil flow, but care must be taken not to over-supply to a point where the fans oil
supply is compromised.
The default working pressure is 30bar. This pressure will need to be adjusted according to local
conditions. For example it will need to be increased slightly (+/-5bar) as the leg is set to work deeper.
Soil types, stone concentrations and desired firming will all influence the pressure setting. The pressure
should not be set so high that the transport wheels are lifted off the ground.
