[AT] How can they farm like that

[rlgoss at twc.com]

That range of slippage is prtty good for ag tires.  On turf tires and others of that naturem, it can run as high as 30%, and it simply wears the sod out over time.  My older brother drives a ZTR that he continually had trouble with when it came to lack of traction.  He finally changed the tires out and put low-lug high-flotation tires on the drive wheels and no longer has the problem.  When I made that sort of change on a lawn tractor that I owned for years, I got an immediate 25% improvement on mowing time and a comparable reduction in gas usage.  My brother is in his mid-80's and rather set in his ways of doing things.  You often have to hit him in the head with a 2 X 4 to get his undivided attention.
