Adding cross shoes spikes to automower wheels

I got some little problems with my Husvarna Nera 410 slipping on the edge of my yard. There's a severe slop and when the grass is a bit wet, the robot cannot get up the hill.

I have found various existing solutions on the Web, vendor ones with Husqvarna all terrains wheels or third-parties with a disc with some teeth you can fix on the side of your wheels. It surely works, but it's a bit pricey (OK, the automower cost an arm and a leg…) and I want to be sure to get something working for this price.

For those who know, running cross country shoes have spikes, from 3 to 16 mm. I was asking myself if putting those spikes in the wheels wouldn't be a good option. With a tap to drill the thread, you got something that is proven to work on the running shoes and quite cheap.

Here's a draft poorly generated with ChatGPT (not at its best).
