We also had to put on a mount plate, it came with the plow. The plate had the receiver in it. It was definitely a pain. Works good but it needs a bit of mechanical advantage by way of a pulley system. We have a circle driveway with a few spurs off of it. Need to lift and set plow down often so it draws on the battery quite a bit.I wish I had seen this two weeks ago. Had to do a whole mount plate underneath mine to do the same Denali plow. It works but it was a pain to get together.
Have you checked with any aftermarket companies, such SuperATV ?John deere does NOT sell a mounting kit and blade for the 860i! They told me they would sell a mounting kit that would have to be modified to fit. WTH!!! Why would JD make a machine that is designed for work and doesn't make a snow plow for it? John deere let me down on this one....just pitiful....time to trade!
