Four Wheel Steering Operating modes   Two wheel steer. In Two Wheel Steer mode the rear axle position is monitored continually and fine adjustments will be made by the system to ensure the wheels keep straight. All three green lamps must be lit up for this to work correctly. You may switch to this position at any time in the field and the rear wheels will straighten up automatically.   Four wheel steer. In Four Wheel Steer mode the rear wheels will always follow the front ones and will give you the tightest turning circle. However, you may find the machine easier to steer down the field if you switch back to Two Wheel Steer after turning. You may switch to and from this position at any time in the field and the rear wheels will re-align automatically.   Crab steer. Crab steer may sometimes be useful when manoeuvring in buildings and in tight corners in fields. The rear wheels turn in the same direction as the front ones allowing the machine to move sideways.   Manual steer (rear wheels). In Manual Steer mode the rear wheels can be steered manually and independently of the front ones. When you have switched to Manual Steer lift the manual steer knob to unlock it and then rotate in the required direction to steer the rear wheels. This is also useful for manoeuvring in tight corners and may also be useful to offset the rear wheels slightly when working on steep side banks to stop the rear of the machine from slipping downhill. When you have set the rear wheel position the knob should be pushed back down to lock it in position. Before switching back to any other steering mode the rear wheels should be centralised with the manual control and the knob locked in position.   Road work. In the Roadwork position the electronics are deactivated for safety and the rear axle will lock. Before switching to this position, allow the rear wheels to straighten up in Two Wheel Steer. After a few miles on the road the wheels may tend to "creep". If this happens slow down, switch back to Two wheel Steer (which will quickly straighten the rear wheels) and then switch back to Roadwork again. An audible alarm and red warning lamp are fitted in the control box which will both activate at speeds above 12 m.p.h. when in any of the other steering modes. Auto mode (if fitted). If the control box has the optional auto mode fitted the system can be made to switch from 2WS to 4WS automatically as the sprayer is switched on and off for ease of steering down the field and for optimum turning on the headlands. To activate auto mode, turn the additional switch (in the bottom left hand corner of the control panel) to the on position and turn the main mode control knob to 2WS. The mode will then change automatically as the main sprayer control is switched on and off. If you wish to use 4WS whilst driving down the field, then simply turn the main mode control knob to the 4WS position to over-ride the auto function. The auto mode function is activated by a single additional input into the 4WS control box. If you are fitting your own sprayer or spreader and wish to use this feature then the wire must be attached to your control circuit so that it is live (12V) when the implement is switched OFF. If you do not have a live connection when in the off position then a relay system must be used. For further information please contact T.J. Frazier. < 42 >
