Looking for a ZTR to mow about 3 acres. Have looked at and driven the Exmark, Toro, Dixie Chopper, Grasshopper, Kubota, and Scag (haven't looked at Cub Cadet yet). Of these, I like the Scag Tiger Cub (52" deck, 24 hp Honda) the best - seems to handle the best and be built the strongest. However, it is one of the more expensive units - price I got from my local dealer is $8200. Does this seem reasonable? What about quality/reliability? Any other units I should look at closer?
