Hesston 6550, Perkins diesel 4505 hrs, 16 ft head, lots of new parts including new conditioner rollers and bearings, pitman arms, new starter, been stored in the shop for several years after all the new parts where put on it. Switched to a discbine and kept this as a spare and never used it, fired right up and cut a little with it until the old rotten belt broke that runs the sickles other than that it should be good to go just dont use it since we switched to discbine 6500 obo
