This is Max making a return appearance here. He's a 100 hp apprx 10,000 lb Massey Ferguson 399 4wd, fitted out with 50 ton winch and forestry package. Here he has a heavy duty plow blade that cost me $300 with all hydraulics, mounts etc. I use it in snow or dirt and did all the dozer work for my new 26x48 ft pole barn with it, leveling and driveways. I used the standard angling plow mount frame under the front end but reinforced it with 3" pipes running back to u channel brackets on the rear axle. When pushing dirt with it I simply use 2 chains from the top of the blade to the plow frame so it can't tip forward like it is supposed to when you hit something while snowplowing. I use regular 3/8 bolts as shear bolts to hold the chain that will break it I hit something really solid. As it has no down pressure, it's cutting ability is limited but works great in pushing loose material around. I'm going to put a sideboard on the left side this winter to be able to make long pushes down my 350 ft driveway.
If the snow gets too deep I fitted it out with a front mount blower last year that you can see at;
