Bought a new pro150-36" instead of a riding mower. Just found this forum after the sale and did not realize the ProG was the new model and the Pro150 was the old one. The dealer was not very helpful in choosing between a 32" ProG and a 36" Pro150. So I picked the one with the larger deck. He is the closest commercial lawn equiptment dealer to my house so that was an important consideration. Any advice on operating and maintaining the new mower would be very helpfull! I have a 10 degree slope on one side of the house. thanks!
