First Of Its Kind Thinking Tractor
The "thinking tractor" is Valmet's own description of its optional Autocontrol III monitoring system. A computer automatically engages the 4-WD, takes care of engine cold starts, locks the rear differential, shifts on-the-go, controls the pto shaft, restricts wheel slip, and controls the 3-pt. hitch to keep the implement at the optimum working depth. As a result the tractor runs more efficiently with less wear and tear on the engine, transmission, and tires.
"There's not another tractor control system like it in the world," says Henrik Bo Andersen, company representative. "As it automatically engages and disengages tractor functions, it lets you know what it's doing. Of course, you can override the system at any time to control any of the functions manually.
"It automatically engages the front wheel drive when wheel slip increases and disengages it as soon as it's not required any more. When engine rpm's fall too low it automatically shifts into a lower gear, then shifts back into a higher gear when the going becomes easier."
In addition, the system reports to you with 18 different types of information including actual driving speed, wheel slip, averages of speed and slip, area worked, partial area worked, driven distance, working time consumed, time and date, remaining working time, cost of work performed, rotating speed of the pto shaft, engine cool-ant temperature, outside temperature, battery voltage, and even monitors some implement functions.
The Autocontrol III option sells for $6,000 on the 120 hp Valmet tractor.
