The hydraulic systems (forward/reverse) marked on the front of the drawbar CAUTION are depending on how the connections are made to the tractor. • Hydraulic system (I): The hydraulic system (I) moves the Hibiscus from the working position to the headland position and vice versa. The 3/8" hydraulic hose of the system is connected to a single acting valve of the tractor.
Connect the Hibiscus to the tractor Procedure Connect the two lower arms of the 3-point hitch to the linkage pins on the headstock. Use the tractor hydraulics system to lift the headstock until it is level. Unlock the parking jack, swing up the parking jack to the highest position and lock it in this position.
Figure 8. Connect Hibiscus to Tractor Disconnect the Hibiscus from the tractor Procedure Unlock the parking jack, swing down the parking jack to the bottom position and lock it in this position Put the wheel wedges in front of the transport wheels and behind the transport wheels.
Move the Hibiscus to the transport position Make sure there are no persons in the area when you move the WARNING Hibiscus to the transport position. Make sure the front axle weight of the tractor is sufficient (use front WARNING weights if necessary) and that you do not exceed the rear axle weight when the Hibiscus is in the transport position.
