Crawler gears
General notes
If you engage the working gears, you can drive
at a slower speed with the same engine revs.
You can engage the crawler gears in order to
drive at an even slower speed with the same
engine revs.
! Never use the crawler gears to increase
the tractive power of the vehicle. The
crawler gears are intended to permit the
slowest speeds when using corresponding
add-on equipment.
! Only engage/disengage the gears when
the vehicle is stationary. Otherwise, the
gearshift may be noisy and the gearbox
could be damaged.
