I had a customer who hired me to till his field, I show up with my tractor/Howard tiller and he tells me how his rocks have killed his tiller...
So anyway, as I drive around his barn, there is two KK tillers, both with blown gears in the side gear drive! It looked like one had been robbed to keep the other one going, but both were now dead.
Well, I tilled his field and yes he did have rocks, but they didn't kill my Howard.
I bet that happened about a thousand acres ago, (which is closing in on TWO thousand acres now) all on my 6' Howard and it's STILL on it's original chain/sprockets!
