Just sharing my experience. Since upgrading my tires and wheels, I hardly ever use MFWD. Snowplowing, in the woods, etc, but the one that surprised me was yesterday pulling a 6’ harley rake up hill. The tractor was working/pulling and using all 38hp and the turbo was whistling, with no problem. IDK I keep finding more benefits from increasing my tire size and I can definitely feel more horsepower getting to the ground vs spinning before.
