Planning on selling my Toro 52" w/b bought it in 2001(need to check my records). Has 15 Koeler, mulching kit to go with it, 1 set of reg. blades and 1 set of atomics, also will leave the Velke fitting on(was amazed it was 30 bucks when I purchased the Velke). As for the hours, I mow between 8 -15 residentials....this year 20+. I'm hoping to get around $3,000. Think I paid $4600 (will double check that) Runs great and all maintenance has been done. It's time to purchase a Z or something similar.
