''Definition'' – A 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.


''Problem Statement'' – A bulldozer is an expensive and specialized machine. Few permaculturists have access to such machines, thereby not being able to perform constructive terraforming activities for improving the ecology of landscapes or for mitigating erosion. Renting a bulldozer costs $500 per day plus transport. Access to a bulldozer allows any community to reduce its infrastructure cost significantly.
==Overview==
A 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.


''Solution'' – The GVCS involves a ready modification of LifeTrac to make it suitable for bulldozing duty. LifeTrac has already been built with high-traction, metal wheel tracks. To allow LifeTrac to have 4-10,000 lbs of pushing force, the drive on LifeTrac must be geared down significantly (3-10 times). The flexible design of LifeTrac allows for an easy retrofit of gearing chain drive, which allows LifeTrac to be converted into a bulldozer at a cost of about $1k, as opposed to $15k for the smallest available commercial bulldozer.
==Details==
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.

The [[GVCS]] variant is being pursued as a [[Tractor]] bladed retrofit with lower torque, and additional weight


''Development Status and Needs'' – The LifeTrac platform is at the Prototype II stage of development, which is sufficient for testing the bulldozer-duty retrofit. We are ready for the design stage of the bulldozer with LifeTrac as the base platform for this development.

Overview

A 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.

Details

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.

The GVCS variant is being pursued as a Tractor bladed retrofit with lower torque, and additional weight
