Help, I'm planning to buy a ztr for mowing my yard/acerage (ex-corn field actually), probably a 25hp-27hp with 60" deck. I'd like it to be able to mow fields and cut trails through tall weeds and even light brush. I know some ztr's are better for smooth, lush lawns, etc. Mine lawn's bumpy, with tall weeds and on trails some brush. I don't need golf-course cut quality, average ztr quality is fine. What's everyone's opinion on the best ZTR for such heavy cutting needs? What ztr's should I stay away from for this kind of use? Thanks.
