But you see what I mean about the retracted deck? If it's retracted, the pin is flopping loose, regardless of the hole it's in.
You can check at Tractor Supply, they have all sorts of pins, some have latches. A pin with a ball detent would be perfect, but a lucky find.
not really, cause if the ball lines up with the groove, it will back out also.
oh, and on my machine, the pin still backs out even when the deck is not retracted. the bouncing around of the machine causes it to back out.
