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.
Safety systems
There are two safety systems built into the unit - one in the hydraulic control valve and one in the
electronic control box. Should either of the systems detect a fault then one of the green lamps will go out
on the control panel and the system will cease operating or ’’lock-out’’. To reset the system, deactivate it
by pushing the "Power Off" switch and then switch back on with "Power On".
The valve safety system will often lock out if the unit is switched on when the engine is not running. This
is normal and will reset itself when the engine is started. The control box safety system will lock out if it
receives wildly varying signals from each axle - this can happen, for example, if the front steering is
operated after engine start-up and before activating the FWS system. If this happens, re-align the front
wheels with the rear wheels and then reset the system as above. It will also lock out if sensor wires or
sensors are damaged.
Should the system fail completely it can be operated manually to ‘‘get you home’’ as follows: Leave the
electronic system switched off after starting the engine and attach the manual lever supplied to the
hydraulic control valve. The valve is situated under the rearmost edge of the engine cowling. Operate the
lever to centralise the rear wheels. The Agribuggy can then be driven and operated as normal.
You will find, however, that the rear steering will tend to creep out of position after a while and will need
further periodic manual realignment until the fault can be rectified.
