Just before lockdown my mum bought a Yardforce electric mower. During lockdown she hit a rock while mowing and it stopped, dead. She couldn't find anyone to repair it at the time, I tried since and it has sat in my garage for a while. I'm a bit loathed to throw it out, so unscrewed the top and it's pretty much some kind of electric motor (like this ) and a board between it and the battery.
I'm guessing if I replace that motor bit it'll probably work... Anyone more electrical than me care to advise on what else it's might be?
Test the motor first.
Be careful though, bare terminals, 240V can be lethal.

No offence given.

it's 36VDC.
I'd have a look in that box/board to see if there's a fuse anywhere, hitting the rock would have stalled it and drawn loads of amps.

In my experience these things are often a simple fix. Fuse or something mechanical. After you check the fuse. With the battery out does the blade spin free? Might feel a little notchy as it passes the windings but should be free to turn. Work your way up through the mechanism until you find something bust.
If it's dead as dead thing with the battery in then likely fuse or similar.
Hope my ramblings help.
Remove the blade/grass cutting elements before any tinkering
Thanks, will check the board.

Not with electrics certainly! None taken.

I would just like to reiterate this.
As it modern battery powered it is quite possibly brushless so you can't just add power to the wire and it will spin, it need the driver board for it to work.
As above simple things first, fuses (possibly resettable) connections. Look out for a sensor that looks like it may have been nocked or moved or damaged. No signal from <X> could well cause it to not start
Then you are into checking voltages but the difficulty can be that there will be interlocks an simulating or working out the correct inputs to make the muC or whatever is running it can be difficult.

Charge the battery. It could be as simple as poor timing with the rock taking the last bit of usable charge.
Start with tool-free basics 🙂
Cant see why briefly stalling a motor would break it. More likely a loose connection somewhere i would suggest.
Additional reccomendation to remove the blade. I found on ours, pushing the blade around to clean it, it can lurch and spin a quarter turn between the steps in the brushless motor, so can damage you even when its off.
Can you try the battery in another tool? Or put it in the charger if it has status lights to indicate if the battery is faulty (popped an internal fuse)
