Ags are definitely the way to go if you need traction, but the problem most folks on this forum have is that they use thier tractors on lawns and do not have enough cash or room for the ultimate solution: One tractor with R1's for off-lawn work, and one with turfs for on the lawn. 90% of CUT's are delivered with R4's which salesman easily talk unsuspecting customers into by telling them the that "they are just as good as R1's in the dirt and just as good as turfs on the lawn". R4's are really only the best tire for industrial applications of which a tractor/loader/backhoe is the best example. For other applications they simply indicate that you lack the cash, the space, or both and are thus forced into a compromise. Comprimise will always result in dissapointment so save up your money, build a bigger garage, and do it right with turfs and/or R1's. Leave the R4's to the industrial applications for which they were designed. Im sorry if I have offended anyone but these are the facts as I see it.
