Reversing the sprayer

When reversing the sprayer, the controller will prompt "Reversing" in
the display. When the track is in "auto" mode, the track will lock in the
position it had when the tractor was stopped. This means that the
same steering angle, if any, will be kept when the sprayer is reversed.

Menu 3.6.1 Track width

Here the track width can be entered. The track is measured from
right side tire center to left side tire center of the sprayer wheels. It is
important that the right track width is entered. The controller will
calculate the speed to the center of the machine and not the speed
of the wheel.
If the track width is incorrect, it will influence the track precision and
the safety factor.
Factory setting: 71 in

Menu 3.6.2 Tractor drawbar

Here the length of the tractor drawbar is entered. The measurement
is from the center of the tractor rear axle to the center of the draw-
bar pin. This has to be adjusted every time a new tractor is hooked
up to the sprayer. When hooked up, check the rigidity of the tractor
drawbar mounts. There must be no sideways movement.
Factory setting: 31 in
Measurement too short: The Track reacts faster, but will make the
sprayer steer too large a curve.
Measurement too long: The Track reacts slower, but will make the
sprayer steer too short a curve.

Menu 3.6.3 Dead zone

This is the non regulation zone when the sprayer is straight behind
the tractor. If the sprayer is oscillating in the hydraulics when driving
straight, this value must be increased.
Factory setting: 2 in
Decreasing value:
Increasing value:
7.12
Over 6" not recommended.
Reacting on small deviations.
Tendency to oscillate that will damage
the boom. High precision, but more
unstable driving with small corrections
all the time.
No oscillation, but tendency to sway.
Low precision, but very steady driving
with less corrections.
Reversing!
