I'm thinking about buying a used Scag STHM - 61" w/25HP Kohler for $3,000. It has 900 hours. Looks great, sounds great and mows great. Last year I used a brand new Exmark Lazer Z - 52" with 23HP Kohler with cannister air filter (which is awesome). I'm thinking about a new Scag Tiger Cub - 48" with 19HP Kawasaki - priced one about $5800.00. Give me your thoughts on what to buy. The used unit, another Exmark or a Cub. I know that all 3 units are good. Just wanted your thoughts! Thanks!!!!!
