It looks like a worm wheel, and the teeth typically start out shaped like that.

Yes, but not to this extent or with chunks out of them. This was actually locked up from a sheared tooth wedged in the valley of 2 other teeth.

Not my greatest photography ever, I admit.

I'm with that guy, even zoomed in I'm not seeing the obvious damage (between the Goop and the camera focus). But yeah that's one of the first parts to go if you can keep the boat-anchor of an engine running long enough to do the damage, haha!

We dont really have engine issues with these. They're Honda GX25s, as long as the plastic stanchion holding the throttle cable doesn't break they run forever, and a whole carb assembly's only $27ish.

We typically only get about 7 months out of the transmission though.

gotchya, they must have changed manus then b/c the last one i threw away was definitely not honda, it was some 2 cycle something that loved to overheat

Oh the 2 strokes are still made, we just buy the 4 cycles for the rental fleet so ppl dont fuck up the mix.

They're about twice the cost but live 4x as long.

The manufacturer grossly oversells this thing's abilities. It doesn't take much to strip the transmission.

and at the same time they WILL do some pretty impressive shit until you blow up the gear box.

I won't swear it's a unique design but I havent seen others like it yet anyway.

The cork gasket is a dead giveaway before seeing the disc shaft.

I'm ashamed of how long it took for me to understand why it's an Arkansas gearbox. DOH!

How do you know the toothbrush was invented in Arkansas?

Anywhere else it'd be named a teethbrush!

Yes I'm a new dad.

You're doing a great job. My kids are getting ready to have their own kids and I'm sure they'll tell them every time they drive past the cemetery how people are dying to get in there!

We used to call big ratchets with a low tooth-count “Alabama” ratchets when I worked at a boat shop.

Knew that was a mantis as soon as I opened the pic! What I found happened to mine was that rocks got wedged between the tines and the lil gearbox chewing up the gearbox cover and even the gear box to an extent. This allowed dirt into the gearbox which, well, yeah...

I ended up cleaning it all out, replacing all the bearings and seals and the worm drive, JB welding the area where the gearbox case was dinged up, and replacing the cover. Was probably overkill for that little tiller but it was a fun little project when I was just getting into tinkering on small engines.

Those tillers are awesome. That was 10+ years ago and that little thing gets zero maintenance, run once a year, and still starts on like the third pull every single spring.
