Rebuilding a 3 Point Hitch Back BladeWritten by Andrew on January 31st, 2011
Rebuilding a 3 point hitch back blade that I bought for scrap.
I figured I’d add a few farm related projects to the site here. This is one that I kinda backed into over the past few weeks. I picked up a badly beaten back blade for scrap this summer. It sat waiting for me to get to until a few weeks ago when I decided to pull it out and see if I could get it going quickly to help clean the driveway. The quick answer is it’ll take a bit of work. I’ve been taking it apart and now feel that it’s well worth saving.
I’ve been discussing this project with my friends at the Machine Builders Network.
I didn’t take a picture of it before I started. Here’s the state it’s in now:
This is the main frame. You can see where the end that has the latch that holds the blade at a certain angle had broken several times and been repaired, with varying degrees of finesse and success. I’m going to have to cut the whole crack out so I can bend things back into the proper position.
The threads at the end of the blade pivot had been all messed up. They had ground groves to hold a cable clamp in place to keep the blade on using a plumbing flange as a washer. Originally there must have been some sort of special “washer” and then a heavy nut with a split pin to keep it in place. The thread is 1″ fine thread. I managed to clean up the threads with a borrowed thread repair file.
Here’s a close up of the bodged up “fix”. A nut will now thread on. I think I’ll weld a plate on to a nut so I can use the “good” part of the threads down near the bottom.
