APU (Auxilary Power Unit) turboshaft engine powering a highly modified golf cart through a hydrostatic transmission. Aprox 50 hp through the trans to the wheels. 5 hp engine is used for starting rather than 2 large truck batteries. The hydrostatic transmission allows for instant forward and reverse changes,without any shifting, and nearly unlimited torque. Top speed was gearing limited to about 35 MPH at the golf course because the ground is so rough. This was a test run and will be followed soon by some high speed runs on flat pavement. Turbine engine was bought off of Ebay for $500 and used cart chassis was $100.

The transmission has lasted 2 years with constant abuse. The truth is that it probably gets more of a workout in the industrial mower it was designed for. Those are usually a lot heavier than a typical golf cart, with lots of starts and stops, grass and sand contamination. The passive trans cooler works very well, without a fan and the oil tank never gets too hot to touch.
