what do ya'll think of new ztr's from deere? i have a 335 jd tractor that i use because 1 large commercial account has extreme slopes. i really like jd tractor type mowers but, need a ztr. only dealers close to me sell grasshopper and dixon, and i don't really like either. my jd dealer gives me great service and pretty good discounts. i am wary of the 25hp kohler engine which comes in the m665. i wish they used a kawasaki i think their great engines. your opinions would be appreciated.
