The idea here was to create a power source on wheels for use around my property. The tractor had two speed controllers onboard, one for the speed control of the tractor itself, and a second with a quick-disconnect to power external tools or loads. So far it has been used for an electric wood chipper, tow-behind cutting deck, 120vac inverter, as well as to provide adjustable DC power for testing motors and electrical experiments.
It is also capable of providing power to, or sourcing power from a solar tool cart with onboard welders, compressor, plasma cutter, pressure washer, vacuum, and numerous other hand tools.
