Arm Float
This is only to be used in verge mowing set up, it will reduce weight on the rear
roller allowing head to move more easily, following small changes in ground
contours in a forward motion, with the aid of a pre-charged gas accumulator.
Operating the Arm Float
To select arm float, first lower the flail head to the ground before operating the
switch on the joystick. The main lift control lever should be operated to take a
proportion of the flail head weight off the rear roller. This is important, as too little
weight on the rear roller will leave uncut areas of grass, too much weight on the
roller will cause scalping in places and increase flail wear and damage. We
strongly recommend the use of auto reset - break back.
When the head is pushed further out more weight will be applied to the
accumulator causing the head to drop, reset with control lever.
As the ground contours alter it is necessary to reset the pressure within the main
lift circuit as above, constantly raising or lowering control lever.
Note:
If Arm Float and Autopilot are both fitted, both will be activated by the joystick
button, however both options should not be used at the same time. To avoid this
the Head Diverter switch is used to isolate the two and will only allow the Arm
Float to operate if switched ON.
Warning
Do not fold the machine up for transport before turning off the arm float and
discharging the pressure from the lift circuit.
