Default Bush Hog repair

Friend of mine brought by a brush hog that needs some welding and repair. There is a hole in the deck, and one piece of angle iron right above the hole is cracked in two. Also the two straps that go between the hitch and the mower deck are badly mangled.

Think those flatbar straps would benefit by being replaced with angle iron straps?

He didnt do the damage he bought it this way.

Hi Tim - I would try to use the angle iron because it is typically much stronger than flat bar. And it holds up better to vibration because it flexes less. Some of those old brush mowers are so rusty and the deck is so thin that it's difficult to weld. You'll see.

Wow!.. That sure is a big hole!

I wonder what the guy he bought it from hit with it?

I'm sure you will fix it right!

Looking forward to seeing the work you do on it!

Tim,
I think you are right about using angle when replacing those flat bars. I've been looking for a 48" mower just like that. One that needs repair, at a fraction of the cost of a new one.
I'm sure you will do him a good repair job. Those decks rust out, just like a lawn mower deck. I read about someone who stepped up on a mower while it was running, and their foot went right through the rusted out deck. They lost their foot at the ankle! I always think of that when I think of repairing a bush hog type mower.

I have to disagree with the angle iron. Yes it is stronger but you need the flex in the bar in this instance. It bent because the tractor made a steep angle while the shredder was still low. Normally it will flex and go back into place but this one went too far. If it was more rigid the deck lid would have been the weak point and it would have caved in.

My opinion from many many hours pulling one on rough terrain.

Good point redneck - sometimes flex is a good thing.

+1 on the flat bar.

Ok some progress today.

#1 pic...guess how much the steel and the bolt and drill bit set me back.

#2 & #3 Aupposed to be a spacer on the bolt at the top of the 3 pt hitch. Notice how the ends are bell shaped now. Its also rusted solid.

So I had to cut the bolt and spacer so I could get stuff apart.

I was originally going to charge a minimum of $100. Now its looking like $175. I might also do some sand blasting too.

Todays progress.

First I went to hook my truck up to the trailer that the bush is sitting on. I will also note that it was sitting on one of the rails of the trailer and then on two cement blocks. This had not moved when I backed the trailer down the hill behind the garage at my house. So I go to move the tounge of the trailer over a few inches so I could hitch it to my truck. When I did that the blocks fell over and I was left with the mower hanging off. (See picture #1)

I eventually got it back on the trailer using a come a long and a heavy duty ratchet strap. Then my engine crane to lift it over one of the rails.

#2, 3 and 4 are of the patching of the deck. Even after heat and hammering the deck was still out of whack. This required a lot of welding to get it all together.

Sometimes its easier and faster to reskin the whole deck.
Just my 2 cents worth.
