Are you happy with the cutting heightIJ If not, you can probably cut quite a bit closer by setting the final drives into the high position. That will tip your cutter bar down so that you can get as low as possible. Next, I would lower the reel until the teeth just barely clear the cutter bar when the float is maxed out at the top. In other words, make sure the cutter bar can't come up and cut off your reel teeth, but otherwise set the reel down as far as possible with the ram stops at both ends. Finally, I would mount the 3" flexible hose behind the cutter bar with 4" electrical conduit clamps. As the short beans fall onto the hose the reel will wisk them into the auger. You should be able to do a pretty good job in 12" tall beans.
