The 'Tesla' mower didn't let me down, but I sure let her down.
I've used it for bush-hogging and trail-blazing through our commie 80-acres of park land.
The good news is, that neighbors helped, chain-sawing small trees and invasive privit. The bad news is that some of the stumps were tall enough for the mower's blade to crash into at full-rpm.
After a few years of that, I managed to reduce the motor's lower bearing to dust. The shaft wanders around and it's no longer dynamically stable.

LOWE'S does not supports parts nor service for the mower. And they no longer sell a 80-Volt mower.
Of all the places locally, which sell 80-V EV mowers, I'm down to Harbor Freight as the single source. They're sold out right now. For a week. I've never experienced a hand tool or power tool from them, so I'll do the gamble. Their Li-ion pack has a higher A-H rating than KOBALT. Price is comparable with what I have.

Denton lost it's only motor repair shop over a decade ago. Dallas would be a minimum 200-miles in round-trips.
When things slow down, I'll pull the damaged motor, crack it open, and see if I can press out the remains of the zorched bearing and replace.
Worst-case, I'll attempt an auxiliary bearing outboard of the original location, and dedicate the motor to an EV bike project. My mad-scientist electronics wizard brother says adding a variable speed control is very easy. 555-chip, a pot., and a few other goodies on a breadboard. And sniff the solder fumes.
