I dream of the day I get to replace my gas ZTR with an electric - no more gas cans, oil changes, spark plugs, air filters, belts, valve adjustments, noise, smell, carb problems, etc etc. I mow around 6-7 acres each week and the gas alone runs about $100 a month. Throw in all the maintenance and a $6,000 gas powered ZTR costs me roughly $20,000 (total) to operate over a 10 year lifespan. Even if an electric was twice the initial price and I had the replace the batteries every 5 years I bet I'd still come out ahead in those 10 years while enjoying all the other benefits mentioned.
