Thanks for the input guys. I don't have an amp meter yet, but one is on order. I decided to give it a try last night at 60 volts, and it went VERY well. About the same speed as with the ICE and the motor didn't get much warmer than at 48 volts. Mowed the whole back yard which was tall grass and pretty wet.
The Z drive is actually Dixon's mechanical/friction drive. Dixon was the first company to come out with zero turn mowers (in the 70's I think) and they used this system up into the 2000's when they switched to hydraulic. It is really a cool mechanism that uses 2 rubber "cones" and two dish shaped discs controlled by the levers to put power to the rear wheels individually.
Time will tell how this all works out, but I am very happy with it and will start making a better battery rack for the front, and covers for the batteries.
Will try wheelies later.
