A friend uses old school bus chassis and just left one axle under it and tows it with a loader..A dt360 or 466 and a manual with a pto frees up a tractor or two...He even put a shed around one and uses it to run the generator , flip a couple switches to disconnect from the main and he is in business

several local farmers have old combines parked at silos for auger powering. usually can pick em up for scrap prices and county fairs been having demo derbies with them so supply may be dwindling some...
Scrap car/truck with the above ideas are also OK but could be more trouble than finding broken down tractors at or near scrap prices.
