And how many electric motors do they sell? I ain’t talking bout the lil pushers....why haven’t they made an electric lawn tractor? Seems like that would make more sense than a DD vehicle you gotta depend on daily to be fully juiced
I would guess there are two reasons why they don't make electric lawn tractors. The first being that you've increased the power requirements tremendously, since you are just turning a blade anymore, but moving the weight of the mower itself and the person riding. That means a bigger battery, more weight...etc. The other reason is that riding mowers have much more significant commercial market than push mowers. So rather just run for 45 minutes once a week (the size of one suburban lawn), they will need to run for I would guess around 5 hours a day. That issue is also why you never see a lawn contractor use electric weed trimmer and blowers either. No time to recharge.
When it comes to a DD, you have the 1st issue I mentioned, needing a lot of power to move the vehicle and rider, etc. Don't think you have the 2nd issue for a lot of people though. If you're never going over a 100 miles a day, you aren't running out of juice before you have a natural time period to recharge. Again, not for everyone, but fits for some. And that's not considering cost to own or environmental impact, just saying that the need to recharge batteries isn't going to be a problem for some uses.
