Clutch vs Shear Pin

   / Clutch vs Shear Pin #11  
Slip clutch is superior in most ways, but only if you keep it adjusted properly to make sure that it has not stuck together solid. If the implement sits outside for extended periods between uses then that usually means freeing it and re-adjusting before every single use which can be a pain. If the implement is kept in a dry barn then you will not necessarily need to re-adjust it every single use, but will still need to periodically check it.

Sheer pin works okay too, and I actually prefer them over the slip clutch for its simpleness as well as cheaper price to purchase on most implement choices. My implements sit outside and I do not want to fool with adjusting the clutch every time I use one. My mode of operation is hook it to the tractor, then grease it and go work. I rarely sheer a pin on the implements that I own (e.g. rotary cutter, post hole digger, and even a hay baler). On an implement such as a 3-pt rototiller I do think I would want a slip cutch over a shear bolt.
