I guarantee, if you hit an unseen obstacle in the woods, even at low speed, your foot would jerk away from the clutch pedal. And if the tractor really did start to do a wheelie, at 1 mph with a 50" tire, it would take about 2s to reach 90 degrees, the point of no return. My bet is you would have trouble keeping your foot on the clutch then, too. Of course, you could put anti-rollback legs on the tractor, as they do in tractor pull events. You could also pull with a scraper blade. Any large implement would stop a wheelie rollover, but not a side rollover. And I still had a close call with a sapling that popped up when it hit the front axle and ran into my chest. It nearly broke my ribs, which hurt for a week. And this was with an HST, where all I had to do was stop pressing the pedal. I am not trying to say which transmission is "better". I am trying to point out situations where there is an actual safety difference. And any system which requires more operator skill to avoid an accident is intrinsically more dangerous. I think that should be obvious. And the original poster indicated a variety os uses for the tractor. Woods use was one of them. That is probably the most dangerous activity a tractor can be used for,
