When we lived in NY I ran my tractor on the road, by the train tracks, and on minor ATV trails. It had smaller tires and was geared for around 45Mph tops. When we moved down here the only place I ride is in our woods and around my dad's property; lots of hills, rocks, tree roots...etc. I repurposed the tractor with larger tires, a rack for carrying a saw, fuel & oil, a locked rear end and lower gearing. Now it runs out to 12mph @ 3800.
