Many years ago I drove a Drott tracked loading shovel which had no diff but a clutch pedal and brake lever for each track. Left to itself it would drive in a perfectly straight line over undulating terrain until a clutch was disengaged which would initiate a gentle turn. Pulling on the brake lever would slow or stop the undriven track for tighter turns.
Last year I spent the morning driving a turreted 432 and got the impression that it had just a diff and a pair of brakes to slow the tracks?? The slightest change in ground conditions or camber resulted in an unplanned turn and a quick tug on a brake lever giving a feeling of instability. I appreciate that having the turret didn't do the C of G any favours but it still seemed very nervous.
The question is, what steering systems do other tracked MVs use?
