so theres a gravely for sale by me, its a 424 with a 40 inch snowblower, the blower looks good but the guy cant get that tractor out of his barn or w/e until spring, or until alot of the snow melts. so since the guy doesnt have a ton of info on it i was wondering are they hydros, any PTO's on them, and how good are the snowblowers? the last snowblower i had i didnt like the fact it was only one stage not 2, and i like how gravely r 2 stage blowers. also could i get a 3 point hitch for this lil tank?
