Hey guys, Im not new to the landscaping business. Had my own for a couple years now. This comming season im looking to finally buy a rider. Most of my lawns are approx. 1 acre. I need a machine thats reliable, fast, and delivers a good cut. Since this is going to be my only machine i thought id ask all you for your advice. Whats the best overall rider out there? *Looking for around a 60 incher probably lookin at a used machine for around 6K how many hours should it have?
