Mowing Anti can opener treatment for rotary mower

[Tinhack]

My old Ford 954 cutter has never had that problem. It's built like a dump truck. I've hit stumps, rocks, old concrete fence sets, cinder block and even an old auto steering box. It took me two years to finally get the back area cleaned up. It must have been a neighbor's old dump site. It's not just the blades, it's how the blades are mounted. A lawnmower style blade wouldn't last a day out here unless you're mowing a lawn. Cheaply built cutters will need modifications. That's all there is to it.

:thumbsup: When a mower frame is stressed, it bends and the blades hit the box. This is why manufactures offer light, medium and HD mowers.

I've tried beating on them with a sledge hammer (can't even tell I've done anything). I don't own a press, but tried jury rigging one using my hydraulic splitter. THat did not work, but I also did not have the guts to push it as hard as I could have.

When the ones I'm taking off now come off, I'm going to bring them to a friend who runs a fab shop and see if he can do anything with his press. I do not want to heat them, since that will destroy the temper if they are heated too far.

I am thinking hyd press will straighten them

I have the use of a large press at work. I have had to straighten the 3pt arms my oldest tractor more than once. I had a guy heat and hammer them, but I only had to back into a bank of dirt one time. He tried a second time. He just never got them all the way straight. I put them on the press and have never bent them again. Being able to use a large press that you don't have to buy and it take up the space is great.

It will either straighten them or crack them
