I have two old Scag STHM Kohler 20HP 61" front deck tripod mowers, real old, like 'em a lot though. Business is good and I got a new office park customer, and I am thinking about getting a couple of ZTRs. Kinda lookin' over the new Hustlers or else a Scag Turf Tiger. Somebody want to open a can of worms for me and make a recommendation? I've seen some inexpensive models out there, need reliable but not necessarily high dollar. Just 'coz its expensive don't make it better.
