Tractor Concept

Essential Concept:

• Hydraulic drive - for ease of power transmission and easy interchangeability of parts
• Bolt-together XYZ construction (like Gridbeam)
• Quick-connect wheel motors
• Quick-connect hydraulic valves
• Stackability of power units (feasibility proven)
• Tracks
• Quick-attach plate
• Interchangeability of power unit between Open Source Car, Truck, Microtractor, and Bulldozer
• Later retrofittability with Modern Steam Engine Power Unit
• Power units in units of 18 or 27 hp, off-shelf Briggs and Stratton for now
• Square tubing - 4x4x1/4"
• 5000 in lb hydraulic motors, 32 cu in
• Parts interchangeability between Microtractor and Bulldozer
