I have been overwhelmed shopping for a zero turn mower. I have approximately 7 acres, 3 lawn 1 pasture...I need a zero turn as the lawn has many beds. I need something heavy duty enough to mow my field monthly, it is pretty rough. I know I don't want a stamped frame. I know I need cast spindles, probably greasable? I know I need a least a 10 gage deck, as I don't want to shake it apart in the field......looked at bobcat, scag, toro, and many others. Any advice is welcome........never knew there were so many options!?! Also think I want a Kawaski engine?
