The weight of ZTRs IMO can really make a big diference of the overall job. The Heavy weights 1500 lbs on my zee..IThink Its a bit too much for todays lawns. Have any of you had experience with running a light machine and compared It to the heavy ones?? What about the tire size ...I know that will make a difference if Its wider It should spread the weight out. We all know how tricky ZTRs can be to try not to rut or tear turf What do you guys think?
