48" Brush Hog Re-Assemble

Re: 48" Brush Hog Re-Assemble

Resurrecting this one, once I found it...

Can anyone tell me the size of the 4 bolts on the stump-jumper for the 48" rough-cut, two which hold the blades and the two that serve as stops?

Are they 5/8"? How long?

5/8 inch diamter, 11 threads per inch, 2 inches long (threaded part of bolt).

Thank you sir! I'll pick up some Grade 8's to prepare for this mod too...

I doesn't hurt if they are a bit too long as there is plenty of room behind the hub. Just remember that if there is too much non-threaded area, the bolt won't go in far enough.

Another thing... if you ever place an order with Power Trac for anything, add in a few of the bushings that the bolt goes through inside the hole in the blade. About every other time I toss a blade, I cannot find that bushing.

Bumping this up for someone's reference.

Have any of you ever thought of taking a 5/16”-3/8”piece of heavy gauge steel pipe, and welding it on the blade. The bolt head would then be on the inside of this pipe so that the blade would not come around and hit the bolt head; instead, it would hit the pipe.

Even better, have a local machine shop make two rings the thickness of the bolt head, then chamfer the outside of it. This way the blade will glide over it when it hits. Just an idea

I've thought about it, but I'm worried that the blade would eventually beat the pipe into a crushed form and crimp the bolt head. I've also seriously thought about taking the drum off, shortening it by a couple inches so that the blades would ride higher. Then, I'd remove the blades and install "normal" bush hog blades that are of the gull-wing design. If those blades spin around, they miss the other blade's mounting bolt. Gee, what a concept!

That's why they're called Bush Hogs and not brush hogs like the cheap imitations. Everything else is just a rotary cutter. Might as well call all tractors mahindras.

Haha a Mahindras, i had to grab a Kleenex to dry my eyes.

I've eyed those type of blades, more than a few time but would have to move the mowing deck upwards to make room for the drop from the blades.
