■ The
new shape and arrangement of the teeth on the cutter bars reduce the power requirement,
and improve piste quality and working speed. The centre-linked rear tiller adapts to surface un-
evenness and is equipped with finishers that help compact the snow layer. The centre mounted
links can be fixed to cope with all operating conditions. Contact pressure, rear tiller cutting depth
and tiller shaft speed can be adjusted and monitored according to snow properties.
■ Environmental safety is achieved by the use of up-to-date technology in developing the engine
with its high-pressure fuel injection system.
■ Completely electronic management is used in the fuel-injection system. This procedure contrib-
utes to increasing overall efficiency, reduces fuel consumption and ensures the ability to start
even in extremely cold conditions. Pollutant emissions meet the current standards and are well
within the permitted limits.
Driver's cab
■ The BISON is equipped with an EN15059 Roll-Over Protective Structure (ROPS) as standard.
The driver's cab is an ergonomically designed composite fibre structure with an optimised field of
view and noise-inhibiting interior lining. The four vibration dampers which were specially designed
for the driver's cab suspension system ensure the utmost ride comfort.
■ The problem of access to the crank assembly and work hydraulics has been optimally resolved
by hydraulic tilting of the driver's cab and cargo area. The BISON also has a heating system with
automatic, pre-programmed temperature control, defrosting of the front, rear and side windows,
electrically adjustable, heated outside mirror and heated front windshield wiper blades. The long-
range illumination of the work area increases the active operating safety.
Lighting System
■ In addition to the normal lighting system, the BISON is fitted with newly-designed headlamps,
which produce a light beam two and half times stronger than the prescribed intensity.
Display
■ The display in the center is for display and electronic control of the most important vehicle func-
tions.
Joystick
■ The ergonomic joystick carries all the functions of the front and rear attachments, e.g. blade or
rear tiller:
□ Start/stop the cutter shafts
□ Raise/lower the attachments
□ Adjust the cutter angle
□ Lateral swivelling and vertical and horizontal floating positions including control of contact
pressure.
□ And more, according to vehicle model
High environmental compatibility
■ The engine is fitted with an electronically controlled injection system. The use of hi-tech solutions
in developing the engine helps make the vehicle more economic, reduces fuel consumption and
pollutant emissions, and ensures excellent cold-start capability.
Steering system
■ The electronically controlled steering system allows unlimited manoeuvrability through the use of
a new digital electronic system, which optimally adjusts engine output to the operating conditions.
Hydraulic equipment
■ The hydraulic units have been optimally designed to deliver full engine output to the tracks and
attachments and thus ensure maximum working speed and reliability. This means an enormous
amount of pushing power is delivered to the front blade.
