I'm new to the forum. I have a YM2000 with the "rice" tires and wish to change to some normal ag tires. The tractor will be working on some slopes on our property so I would like it to have a wider stance and maybe lower the center of gravity some. Are there any suggestions for tire and wheel size, like some wider 16" or thereabouts? I'm guessing the rear bolt spacing is 6 by 6", I'm not sure of the front is (4 by 6"?). I want to be able to pick up some used wheels to do this, like Kubota or something. Thanks in advance.
