I built a heavy hitch from new steel - ballast/hitch combo. The tractor weights are old Ford ballast I got from a local guy, sand blasted & repainted orange. I added a couple of lead bars I had - total 450lb.
I built a "toolrack" for the tractor. I can pull a wagon plus carry chainsaw, pruner, gas/oil and the tailgate doubles as a work shelf. The frame is mostly from re-purposed steel. Colour scheme is "Kubota"
Retired. Built some implements for use around the property for a sub-compact tractor. I have a stick AC unit and oxyacetylene. I built a PTO power broom, rear ballast, chain harrow frame and working on rear pallet forks.
