• High range (rabbit) – high speed drive (4.5 mph) with
booms in the stowed position.
• Low range (turtle) – creep speed (0.8 mph) with high
torque drive operation with booms in any position.
The drive range operates in low when the booms are out
of the stowed position, regardless of the position of the
drive range switch.
Boom Speed Knob
