When you break a sheer pin, you have to replace it with a new $0.25 bolt.
When you hit something with a clutch, it slips & you cary on. Every spring you have to spend an hour or so loosening up the pile of bolts holding it together, engage the PTO so it slips & frees up the clutches that have rusted together. Shut things down & tighten the bolts back up the same excact number of turns you loosened them.
I thought I got a slip clutch on mine, but when I got ready to do my first spring maintnance, I was disappointed to find I had been mislead by my dealer & it was just a sheer pin hiding under the shields not the clutch they said it was. Still torqued at the dealer, but the simple fact I don't have to wory about doing any maintnance on it & have yet to sheer a pin make me not regret having the pin.
