F I E L D O P E R AT I O N Your Speedtiller Powerflex is a high performing speed disc. You will need to become familiar with the settings and adjustments to get the full benefit of your new machine. Front wheel hydraulics and heavy trash conditions. For undulations float mode. Front wheel hydraulics control the depth of cut for the Powerflex giving more accurate depth control for hard soils and heavy trash conditions for undulations such as farm over contours etc. the roller hydraulics must be placed in float mode. MACHINE SETTINGS • Rotate control bar cranks so valve-stop push-plate is furthest from hydraulic valve stop button, to allow depth and tilt setting to be adjusted on the go. S ee figure 36 & 37 • Remove and store all ram stops from rear rollers (if fitted). • Operate wheel hydraulics (RED) for setting depth. • Operate tilt hydraulics (BLUE) to set front to rear depth ratio (TILT) and for best on line tracking. S ee tracking adjustments pg 31 • If machine pulls to the right; lower tilt. If machine pulls to the left; raise tilt. • Note that wheel hydraulics may need minor adjustment whilst fine tuning tilt adjustment (as front disc height also changes with tilt adjustment). • Once desired depth and tilt setting (front to rear depth ratio) achieved, rotate each control handle to depress the two valve buttons, which will therefore maintain this setting. *NB - Assure that all discs engage with the soil for positive rotation. Where heavy trash conditions and loose soils are encountered, machine may have to slew sideways slightly to achieved desired result.
WARNING NEVER REVERSE MACHINE WITH ROLLERS ON GROUND. TIP* When setting up machine in either mode always start shallow then adjust down to required depth setting.
WARNING
WARRANTY WILL BE VOIDED IF TILT OR REAR ROLLER HYDRAULICS ARE FORCED DOWNWARDS CAUSING ROLLERS TO CARRY EXCESSIVE MACHINE WEIGHT WHEN TURNING AND ON HEADLANDS.
