	For us at [http://~~openfarmtech~~.org~~/weblog~~/ Factor e Farm], LifeTrac will be the backbone of our agricultural, agroforestry, and land stewardship operations. It will also be used in construction, power generation, and possibly other workshop tools. Interestingly, hybrid hydraulic drive also applies to cars - here's an example [http://www.fordmuscle.com/blog/ford-to-build-60-mpg-f150/112114]. The identical hydraulic design, minus agricultural implement features - can be used with a car - simply by using faster, lower-torque wheel motors.

	The basic drive is all hydraulic, and all implements are run hydraulically as well. Three hydraulic motors - PTO motor, high torque motor, and winch motor are used for accessory power applications. These can drive the following devices which we are also building contemporaneously:		The basic drive is all hydraulic, and all implements are run hydraulically as well.

	Based on [http://forum.opensourceecology.org/discussion/comment/2994#Comment_2994 this forum exchange] perhaps the LifeTrac could get a righteous set of proper tank treads. Take away the 4 hub motors and convert the wheels into idlers. Install new (bigger) motors on the rear pillar. Install sprockets on the new motors. Make longer metal tracks that go around the two tires and one sprocket (on each side). Now you've got something that maximizes the useful torque and grip available in the design. A company called [http://www.asm-steuerungstechnik.de/index.php?id=9&L=3 ASM] has this [[steel chain sprocket]] that fully engages every link and actually looks simpler than a normal sprocket.
