Some years back I bought an Allis Chalmers model C with a wide, adjustable front end. I also purchased a Woods mid mounted mower, but ended up buying an 84 inch model 306 because I wanted to mow at least the width of the tractor.
While the tractor did okay with the mower as long as the grass wasn't too overly tall, once it hit some tall grass, the engine on the C was really not adequate. At only about 20 hp, it actually did well all things considered. There are only 3 forward gears which compounds the problem of rpm vs. forward speed.
The mower operates off the belt pully, lift hydraulics are from the original Allis Chalmers hydraulic pump, also run from the belt pulley drive. The front end is very lightweight, the tires narrow, making it steer well as long as the steering box has been adjusted and lubed and is not worn out. I installed an original can style muffler with a very short stack which makes it easy to operate under low hanging branches and also allows it to fit into garages with low clearance.
The brakes leave something to be desired as does the height of the platform. A problem getting up there for those in poor physical condition. The seat however is very comfortable once you get there. The Allis Chalmers C is a relatively simple tractor to maintain and parts are still easily available. It uses very little fuel (gas) making it very economical to operate.
