Looks like the removable pin there is an R-style pin (for easy disconnect) while the smaller digger bucket uses a cotter pin. Jeez looks like they are using a combination there. Nicely posted @jakeblended !
Yeah I watched that video for a lot of my reference. The quality is kinda poor on the 2nd video I had to watch it a lot haha.
@pfbourassa you’re going to want to watch this 2nd video for the front loader bucket.
