Terratrac TT75
Steering
& Tires
The
intuitive steering system.
Just the simple press of a button, or
the flick of a switch, allows the optimum, safest, most economical and
ground-protecting type of steering to be selected for the job at hand:
Four-wheel, front-wheel or rear-wheel steering. The steering system is
hydrostatic and is based on a "load sensing" principle.
Inductive sensors detect and synchronize the current position of the
wheels. Only after the wheel positions are correct for the selected type
of steering is an automatic switchover made. An indicator lamp shows
which type of steering is currently activated.
Thus
the driver can relax and concentrate on the job at hand and change type of steering without risk even in situations where this was not
possible until now. The advantages of front-wheel steering with which
everyone is familiar have been combined without compromise with the
mobility of four-wheel steering. But what is really special is that Aebi
has succeeded, in spite of rear-wheel steering, in retaining the 45º angle lock for the front wheels. The turning circle with four-wheel
steering is just 9½ feet.
For very special applications, a
quasi "crab-mode" steering can be selected.
Always the
correct driving mode.
Just what does this mean: You drive and the
control Aebi Terratrac TT75 - whether using the accelerator on
roads or the or the multifunction drive lever cross country - just like
a car with an automatic transmission. Aebi achieves this enormously high
level of operational convenience and safety thanks to the built-in
AUTOMOTIVE CONTROL of the infinitely variable hydrostatic drive which
can be changed under load. This uses the very latest technologies and is
highly efficient. The speed range is 0 to 24.9 mph and can be adjusted
in two levels with high precision to match the current operating requirements.
This means that the Aebi Terratrac TT75 always transmits its full
power simply and directly to the surface but nevertheless travels across
the surface softly and gently. The Terratrac transmission cannot be
overloaded. In the event of an overload the engine does not stall, but
rather the speed is reduced right through until the vehicle is
stationary.
