Let me set this up:
Track: closer to the soft side
Tractor: set up for 4500lb, new 13.9x38 on 12" rims with 10psi. At end of pull, tractor is diggin' in with front starting to float off the ground.
First off, I'm guessing that when it starts digging in, the dirt in front of the rear tires starts acting like a berm so the tire cannot roll over it,so it continues going down. I checked the dirt in wheel rut, looks like it is a little high in the middle
Next tractor: same weight class, but older tires of the same size, half worn. It pulls farther than mine.
Neither tractor has cut tires.
Questions:
Can I do anything with my current set up to gain extra ground?
I would think that while the older tires are stiffer than new ones, wouldn't they do the same & spin out sooner than mine?
Are the new tires hurting me that much?
Thanks in advance!
