TIP* When setting up machine in either mode always start shallow then adjust down to required depth setting. positive rotation. Where heavy trash conditions and loose soils are encountered, machine may have to slew sideways slightly to achieved desired result. • Wing hydraulics (YELLOW) MUST be placed in float position for normal conditions, However if some down pressure is required, Lift wing torsion. system just 15mm off stopper plate. • Operate wheel hydraulics (RED) for front depth setting. • Operate tilt hydraulics (BLUE) to set front to rear depth ratio (TILT) and for best on line tracking. S ee tracking adjustments pgs 30-32 • Once front to rear depth ratio (TILT) setting is achieved, rotate handle on control bar to compress valve button and maintain this setting. • EXTEND WHEEL LIFT RAMS (RED) TO LIFT MACHINE WHEN PERFORMING HEADLANDS & CORNERS. *NB - Assure that all discs engage with the soil for Your Speedtiller Powerflex is a high performer combining a choice of operating modes. You will need to become familiar with the settings and adjustments to get the full benefit of your new machine. RIGID HITCH MODE In this setting the front wheel hydraulics control the depth of cut for the front and rear gang. The tilt hydraulics control the front to rear depth relationship. This mode has more accurate depth control for hard soils and heavy trash conditions, and is suitable for undulations such as farm over contours etc. The roller hydraulics must be placed in float mode. SETTINGS • Rotate control bar hydraulic valve stop out anti clockwise a few turns to allow tilt setting to be done on the go. S ee figure 35 • Remove and store all ram stops from rear rollers. • Roller hydraulics (GREEN) MUST be placed in float position.
