Proof of Concept of MicroTrac Scalability
The MicroTrac is overbuilt to 8000 lb of drive torque plus the ability to carry an extra 6000 lb of weight outside of its existing 2000 lb weight. With the structural Power Cube as the basis for other attachments, the MicroTrac can be scaled in size to build bulldozers by stacking 3 MictroTracs together for 24,000 lb of torque at the tracks. See initial testing of weight handling capacity, where the MicroTrac carries 6000 of dead weight, and is shown running in idle:
Go to Hackaday - 
Here is a partial prototype of adding a Driver's Cab, second Power Cube, and loader arms to the base tracked platform consisting of tracks and power cube.
The condition of satisfaction for torque was idle -
The Bulldozer is a high-traction, earth-moving machine indispensible to building ponds, berms, or other earth-moving tasks such as building roads or clearing land. See Bulldozer Specification
Most often, bulldozers are large and powerful tracked heavy equipment. The tracks give them excellent ground hold and mobility through very rough terrain. Wide tracks help distribute the bulldozer's weight over a large area (decreasing pressure), thus preventing it from sinking in sandy or muddy ground. Extra wide tracks are known as 'swamp tracks'. Bulldozers have excellent ground hold and a torque divider designed to convert the engine's power into improved dragging ability. The Caterpillar D9, for example, can easily tow tanks that weigh more than 70 tons. Because of these attributes, bulldozers are used to clear areas of obstacles, shrubbery, burnt vehicles, and remains of structures.
