I actually looked at the correct blade for my tractor and after they picked me up from the floor when they told me the price, $1800, I figured there had to be a better way......so, I took a bunch of pictures of the correct blade and quick hitch and tried to model mine as close to what the factory designed. With only one exception, my bracket hooks up exactly like the factory quick hitch. It slides inside the factory brackets like the factory, but instead of being tied together with the quick hitch, mine extends up the front of the bumper and has two 9/16 holes in it to line up with the holes in the bumper. I made pins for those holes also, so basically there are three pins that must be installed to attach the bracket. No tools required. I will end up with only about $400 in the entire project. The only four things I had to pay for was the blade I found on evil bay pretty close to home, JD brackets for the 2305, some fittings, and of course a 20' stick of 13/16 rod. It is really nice to have friends that owe favors and own powder coating, steel fab, or hydraulic shops. Even without the favors, I would have still only had $600 or so in it.
How is your project coming along? That blade you are using looks to be about five feet? Will it be all hydraulic or electric?
