Who uses a motorized tug?

[MD83driver]

I found a used Lathan Manufacturing Co. "Areo-Tractor" Gasoline
Powered Tractor for pulling industrial material carts that was converted to an aircraft tug. It was in miserable shape. I removed the motor, hydro-static drive and the hydraulic jack. Changed it over to two electric motors, speed controller, added an electric hydraulic jack to lift the nose wheel and added lights. Works great. Bought most of the components off of Amazon and eBay. The Concord batteries were not airworthy for aircraft, so I opened them up and refilled the distilled water, and reconditioned them using a HFT charger. I have added two of those chargers to the tug permanently to recharge the batteries after use.
