Nice looking rig Jim. I'd bet that hoe attachment back there puts a lot of strain on the frame.. Were they using the hoe attachment when it broke? That 3/8...1/2 reinforcement piece is pretty beefy. Looks like the engineers failed on that model. You probably got a good deal with it being broke in half. What's it got for hours?
The frame reinforcement piece is from John Deere. And is one heavy mass of steel. Fit like a glove too. Should have come with the back hoe. About 1600 hours I believe. Runs great so far.

Here's one thing that I forgot that I screwed up along the way. There is a brass nut in the side of the plastic fuel tank. It is the mount for the coolant overflow bottle. Well, the bolt was seized in the brass nut. I figured there had to be a nice amount of plastic holding the nut in place. I spent a lot of time trying to cut around the nut. Trying to grab it to back out the bolt. Just kept spinning the nut. So I figured there should be plenty of plastic around the nut, so why not use a hole saw to cut around the nut and pull it out. Well there is hardly any plastics and I ended up with a 1" hole in the side of the tank.:doh I then had to figure out how to save the tank. Since the sending unit is in the side of tank and doesn't leak, I figured I'd whip up something that would use the same gasket. So I machined a piece from some hot rolled steel I had. So far so good.IMG_20201020_153121.jpgIMG_20201024_122850.jpgIMG_20201023_064710.jpg:fingerIMG_20201024_125825.jpgIMG_20201024_125758.jpgIMG_20201024_125804.jpg

Thanks guys. It was the repair or replace the tank. The tank is a real pita to replace never mind the cost of the tank. This repair cost a couple of dollars and a little free time before work. Luckily the tank filler opening is large enough to reach in and hold the slug in place while I started all of the screws.

I was contemplating using aluminum, lighter and easier to machine. But, I have no idea how it would hold up in the diesel fuel plus I didn't want to strip the screw holes if I had to really crank down on the screws.

Since I got the tractor moving under its own power, I've been kicking around what else I need for it. I figured if I want to use the tractor to move a trailer around the property, I'll need a hitch. And if I use the tractor without the back hoe, I'll need a weight box. Of course I didnt want to pay a few hundred dollars for the box and then buy weights. So I whipped the framework up including a 2" receiver. Then decided to make my own weights. I used a 2x4 and some scrap plywood to make a form. Then cast 6 concrete weights. Rebar was used for a "handle". The weights are sized to fit nicely in the box.IMG_20210410_104943.jpgIMG_20210410_104928.jpgIMG_20210410_070013.jpg
Each weight is between 90 and 100 pounds. One 80lb bag plus a little extra of Quick Crete. And it is (Harbor Freight) quick hitch compatible.
