Update: While you are welcome to read the post below, make use of the documents shared, and learn from the comments, I have come to a crossroads with this mower. The deck motor driver has failed twice on me. So I believe I will be purchasing a new unit. This is what it looks like.
Zero Turn Mowers
Hustler Turf Equipment Introduces Electric Zero-Turn Riding Mower - Lawn & Landscape
All the features of a premium commercial machine built into the perfect small acreage mower. For the Residential User looking for a high quality Zero Turn at a price that's hard to beat. Built to mow commercially, or maybe just to be used by the savvy land owner, the Raptor XDX is more than capable no matter your intended use. The Super Z frame with the reliability of a diesel, a Contractors best friend.
Hustler Zeon All Electric Mower
Hustler Turf Equipment introduced an all-electric zero-turning radius riding lawnmower. The Hustler Zeon is the result of groundbreaking innovation and precision engineering. The machine's quality and length of charge is good for up to 80 minutes of mowing time — enough to mow more than one acre. The Hustler Zeon features nearly zero maintenance with no belts, filters, fluids, pulleys or plugs and is very inexpensive to operate.
The problem with gasoline and diesel mowers is that they have many maintenance issues. Every week I find myself at the gas station filling my truck and gas cans. Until now, no one has made a serious attempt at an all-electric mower, and after testing the Hustler Zeon I can see why.
