	While long-term performance only will determine whether LifeTrac is worthy of its implied lifetime-design name - the results after 1 year of operation are promising. No visible leaks are to be found on any of the hydraulic motors and cylinders.

			===Observations===
	*Hydraulic drive via a diesel engine reduces the mechanical complexity by eliminating the transmission-clutch-differential-drive train-steering-braking, and replacing it with hydraulic flow, valves, and hydraulic actuators that perform all of the above functions		*Hydraulic drive via a diesel engine reduces the mechanical complexity by eliminating the transmission-clutch-differential-drive train-steering-braking, and replacing it with hydraulic flow, valves, and hydraulic actuators that perform all of the above functions

			===Improvements Needed===
			*In muddy conditions, the wheels spin out completely, so machines post LifeTrac VI have optional tracks as a possible module.
			*Roll-over protection should be added.
			*Power Cube module should be added instead of using a dedicated engine.
			*3 point hitch module should be added.
	===2015 Review===		===2015 Review===
	*As of Sep. 2012, the turbo pump on the built-in diesel engine sprung a leak, and is an estimated $1000 fix. We can avoid this by simply putting a Power Cube on the back of this tractor. LifeTrac I did not have a separate Power Cube - but a built-in engine. Since then, our modular design evolved to [[Power Cubes]] as modular power units. In 2014, a student inadvertantly destroyed the hydraulic system. As of 2016, Refurbishing the tractor with a Power Cube, as well as refurbishing the hydraulics - is being considered for showcasing this tractor as a historic artefact of Factor e Farm.		*As of Sep. 2012, the turbo pump on the built-in diesel engine sprung a leak, and is an estimated $1000 fix.
