I share part of my gravel driveway with my neighbor, and he has two sons who ride ATVs all the time. So, between that and my NASCAR-trained wife, I need something to smooth out the ruts.
I've tried grader blades- which do in fact work well, but will only move so much at a time. I need something to do more when needed. Dozer blades work well for moving quit a bit per pass, but it's hard to get the "grading" effect with those as well. I decided to try a box blade.
I used an older 48-inch dozer blade to start. It was rough, but I wanted the curved section both for strength and so it would really dig in if I needed it to. Then I welded 3/16 plate on the sides, and used angle to make a "cradle" on top. I want to be able to use the blade on both my 3-point Bronco 14, or with a clevis hitch on any other tractor. Here's the first setup:
I also made sliders on the bottom edge for when I use it with the 3-point:
This first part was just tacked together. It was so rusty that I didn't want to finish weld it until I cleaned up all the rust first. Normally I would use electrolysis to remove it, but my tank is put away for winter. So I sent it to the sandblaster.
While it was there, I made the 3-point adapter. Since I wanted it to be used with a clevis hitch also, the adapter needs to come off easily. It will be secured with four 1/2 inch hitch pins in the cradle.
If I use this with a clevis, it will need to have some kind of support in the back. I don't want it to dig in all the time, so I made a wheeled carrier for the back. I had originally planned on using casters, but they create more problems than they solve. I just used an old set of 5-inch wheels.
The carrier uses the factory mount points for the blade, and will have another bracket attached to use the multiple holes for different cutting height:
And this is the final mock-up. I still have to fab the clevis hitch adapter, and reinforce the cutting edge. I'm still debating on whether or not to add a scarifer rack up front.
I'll also be trimming the side plates down a bit, and I'll use those pieces to brace the center of the blade. I'm looking forward to trying it out.
