If you've ever had deck support pins vibrate or rattle out, here's my solution. Locking pins. Simple solution to save a bunch of inconvenience. They should have been standard.

Its not from abnormal vibration. Just the normal mower vibrations, as well as rumbling along on hard ground. Still, it was a 10 minute fix for something I think should have been standard. There are locking pins for the front deck mounts pins... why not these, too?

agree...factory clevis pins installed have never worked back out on any of my machines, with one exception: a kubota tractor 3 way pto suspension....but that was heavy brush slamming a clevis pin with enough force to snag and pull the pin out.

I've never had clevis pins snag or pull out on mowers though. (and I do a LOT of mowing in all kinds of conditions and thick stuff)
