I scavenged some angle iron and tube and cut up the parts for the frame. The articulation moves the right way, I'm happy I didn't screw that up.

Unfortunately I'm waiting on an order of welding rods, coronavirus restrictions in these parts don't allow us to go to stores unless it's essential.

There's my old 1952 Fergy TEA-20 in the background, she still pulls out my firewood every spring and hauls a wagon around for rides.  She's part of the first generation of tractors which replaced horses and runs great even after 68 years of hard work.
