This afternoon I was attaching casters to a mobile base for my new blast cabinet. I had mistakenly purchased 1/4 x 1" bolts, when I should have purchased 1/4" x 3/4". As I was clipping the ends off the bolts to make them the right length, it occurred to me that some here may have an interest in the tool I was using given that it's branded Deere and all.
The tool has a Deere part number TY3459 which did not return a google hit. However I was able to return a hit from one of patent numbers - 3716879.
One side has several SAE threaded holes and an a couple of cutter slots. Install the bolt through the threaded hole, clip the extra off. When the bolt is unscrewed through the tool threads, it fixes the ones that get wrecked during the cut-off. The whole tool is about 18" long.
