Madison - good catch. We had 2 smaller wheels there in the original design, then we went to 1 larger one this week but haven't tried it out yet. The forked paddle was always multi-functional - push down the bridge, push in balls and lift them to the conveyor. The design thought behind adding the wheel was first that we might put it on the barrier and lift the front of the chassis up to drive over it. Then we decided it would be a good idea to have a rolling interface at the bridge. The balls were an afterthought, figuring we would just slide them rather than roll them - the small wheels were too low touch the balls, and this one is marginal. We may put the smaller ones back on in addition, closer to the ball centerline.
