Reply to comment by themadevil in Lawn Mower Issue - No Nuts Holding The Wheels On - How To Fix? by PrettyMuchAMess

Hmmmn, I'll look into how the axles are attached, given how cheap everything else is it's probably just held in place with bolts. Though vis the thread's breaking - shouldn't that not be an issue? Weight bearing axles are usually steel and the one on this mower appears chromed. Plus, while I'm not the gentlest, if it gets stuck I know it's easier to stop and check what's happened than to to just brute force it.

If they're using speed nuts to hold wheels on, I'm loathe to assume they're using the correct axle materials.

Edit: On second thought, it should be enough to add threads as long as the axle is thick enough per spec, I'd just suggest doing a manual pull check once it's done to make sure you're not going to be three-wheeling it home.

It's over 1cm in diameter, too blobby (hand cutting a lawn with a sickle is "fun") though to haul it out of the garage to check. Think it's about 1.2-1.4cm roughly. Hence why I thought it could take a thread and nut.

Hah, I can easily carry the stupid thing it that happens. After all it's at home and only for home use.

Worst comes to worst I'll no. 8 wire it and jerry-rig a solid solution. Already had to do that with a flat pack bed that fell apart due to too short screws and no anchors for the bolts.

Or I can just transplant the new motor into the old lawn mower, since it's wheels have stayed on. Unlike it's metal exhaust cage, which is still held in place by annoyingly thick wire from old climbing plant fence support wire.

Sounds like threading is an easy first option, and you have other options if that doesn't work for some reason. Let me know how it works, and good luck.

Not speed nuts, more like these: https://www.anzor.co.nz/washers/internal-tooth-lock-washers Only with thinner metal on the teeth and the teeth are wider too.

[edit] - bless google image search, even with inaccurate search terms it can be rather useful :3 As it appears these are very much the same as the ones on the axles: https://www.ubuy.co.id/en/product/R9C66IW-oiiki-200pcs-m2-m2-5-m3-m4-m5-internal-tooth-starlock-washers-quick-speed-locking-washers-push-on-sp
