A Microtractor: A tracked machine that is similar in functionality to a Toro Dingo brand utility machine but has more power. We will use a 16 hp Power Cube – our hydraulic power unit. Because our build system is modular, we can add a second Power Cube to this tractor for a total of 32 hp for more demanding tasks.
Tractor: A 32-64 hp tractor that is a larger version of the MicroTractor – using many of the same components. As the first team works on the Microtractor, a second team will work on a larger version of the tractor. We will use 2 of the same Power Cubes, for 32 hp. We can add 2 more, for a total of 64 hp.
Solar Module: The beauty of hydraulic power which we use to drive the tractor is that a small power source can still move a heavy machine – only slower. Thus, a 2000 lb or 6000 lb tractor can still move – and with as much force – on a single solar panel. As such, we will use a solar panel to run a small electric Power Cube – which runs the tractor. This will be our proof of concept that a tractor can do useful operations on solar power – shining new light on the capacity of solar power to fuel agriculture. This leads to automation – where a slow-moving (3 feet per minute) tractor running on solar power can do useful work – such as weeding or pulling chicken tractors.
You'll learn about solar power, charcoal power, and all of the bits and pieces you'll need to build your very own eco-tractor.
All of this is good, but all you really need is a converted 2 cylinder motor, a steam pressure container with pressure releases, and a electric cook stove top hooked to a 250 amp alternator with leads around the dc conversion diodes It could also be powered by a 1-1/2 horse motor hooked to the alternator which would power the motor. Either way will work. The Alternator puts out 220 volts and 250 amps The Motor draws 16 amps which would leave the rest of the 234 amps to run the hydraulic motor.
