Must be wet/soft/lowland? Usually a tractor won’t do that.
Nope I'm up about 1600 ft on a hill/mountains, it does it in wet and dry conditions. I have 2 1720's, both with fel's but 1 has a woods bh750-2 backhoe and 1 i use to switch out implements. The one with the backhoe has the taller 12.2 tires and the one without has the smaller 11.4 tires and both leave ruts. Like I said before I think its because the tires are somewhat on the narrow side because my neighbors Deere 310d extendahoe leaves less ruts. Crazy.
