My father has a JD790 and recently looked into a front mount snow blower for it. I think the price he got was at the dealer that sold him the tractor 4-5 years ago. He was quoted around $4000.00 including the kit to install the mid mount PTO. Installation not included in the price. Has anyone bought one of these? Is that a fair price? Are there any out there that will work and aren't green? If any one has one, how dificult is it to put on/ take off ?
