I'm looking at a Toro Proline walk behind with 52" deck. Kohler Command 15 HP engine with 500 hours on working meter. Trac Vac model 470 with 5 HP Briggs & Stratton motor. The mower is in very good shape and never been used commercially. I've got him down to $1650 for the mower and vac. Do you think this seems like a fair deal for the mower, or no? I've never had a trac vac, would this be very beneficial for fall cleanups? Thanks!
