WideTrac Operation & Parts Manual
Machine Setup & Calibration
The controller must be calibrated every time it is used with a different tractor. Calibration
finds the belt speeds possible with a tractors available hydraulic flow.
If calibration is not run, the spreader will not have the appropriate available speed range
and can cause the machine to spread inaccurately.
With power and hydraulics connected press and hold the button.
-----MENU----- will be displayed, keep holding
button until “1) Wheel Size” is shown.
Press button to move to second option
menu, “2 BELT CAL”.
Press to enter menu. Instructions for calibration will be displayed on screen.
During the calibration process, keep away from exposed belt at front of machine as it
may begin rotating without notice.
Set tractor engine to operating RPM or set flow to at least 60L/min. Engage hydraulics
and then press on controller.
The controller will find and set values for minimum and maximum belt speeds depending
on tractor hydraulic flow available at set RPM.
Wheel size is the diameter (in millimetres) of tyres fitted to spreader
– This option is set
from factory.
If wheels & tyres are changed, wheel diameter measurement must be checked. Ensure
tyres are at correct pressure, park the spreader on flat, level ground and measure the
height of the right rear tyre (closest to the floor gearbox). Adjust wheel size setting in
menu to match.
