Steering and
braking
The steering clutch is
tighten by pressured springs and separated hydraulically with
oil-type, multi-powder-metal discs.
The brakes are oil, two-direction
floating band with mechanism foot pedals, hydraulic boosted. The
steering and braking can be actuated in one control.
Transmission, steering and
braking operation
The operation of
transmission , steering and braking is controlled by single lever
. Transmission, left and right steering and braking can be
realized for three speeds forward and three speeds reverse by one
handle .
Final
drive
The final drives are double
reduction with spur gear and segment sprocket, which are sealed
by duo-cone seal
