Brush hog shear pin problem

[ptsg]

Is this style of shear bolt PTO shaft is not used in the US or just less common? It's so easy to replace the broken bolt and also slightly cheaper since it uses smaller M8 (5/16") bolts.

Never seen that style... looks pretty good.

ptsg, I have one like that, so "yes" they are in the US.

I've mainly seen that style on snow blowers. Probably because snow blowers are not designed and built in the US as much as other implements.

I could forsee that design breaking as soon as you engage the PTO on a brush mower. Mine stops and starts with quite a jolt.

Not a problem here and I have one on the brush mower and other on the tiller.
