I bought a new 570 touring earlier this year mainly because I wanted a new quad as I'm getting a bit old for my 400ex. I also wanted something to leave at my mother's house so she could plow with it. She lives in an area that sees about 220" of snow a year.
I ordered a 60" Denali plow in the summer, the only thing I didn't like was her having to get off the quad to turn the plow, so I started googling all sorts of things. I just didn't want to pay $600ish for the motoalliance actuator. I saw a few people use a winch setup, but none of them had any comments on durability.
Cabelas has a complete motoalliance Midnight Viper winch for $79 shipped. This winch has a hole straight through the drum so you can have the rope pulling in either direction, you just run one side under the drum and the other side over. I cut a 20 foot section and ran it through the hole 50/50, then wrapped it around the drum.
I welded the winch plate to two 3/16x1 steel bars. I then welded that to the push tubes of the plow. I then hooked up the winch switch to the orange/yellow wire, the contactor and ran the blue/yellow wires down to the winch on the plow.
I went to Ace hardware and bought two turnbuckles, ferrules and clamps for the wire rope. Now... I had to plan this 240 miles away from mom's house so what I currently have needs improvements, mainly heavier turnbuckles and different power management going down to the winch.
The hardest part was taking 25 minutes getting the rope tight around the drum, I had my nephew help me with that part once it was assembled and hooked up to the skid feet.
Will it last all season? I dunno. The wire rope is going to be the weak link because of the angle against the fairlead. It's setup to take apart in a minute if the rope does break. All in I'm under $100, if it's a shit idea I still have a spare winch out of the deal.
