The tab on the first photos is part of the outer case you can just see on the photo of the pawls. If you look at the outer edge you can see the tab/case, and this is rotated back with pawls closed, and rotated forward to open. It is only rotated the length of the slot in the photo of the outside of the wheel. I'll take more photos tomorrow when I get a chance to pull it down more. The main gearing is in the grease pot that you noticed earlier above the reel, but I'm not sure yet about the drive wheel where the pawls connect. The gears look in fair condition without any tooth loss from what I've been able to see. I have a trctor but I also have a John Deere 6 x 4 Gator that I'm pretty certain will tow it. Really looking forward to trying that!
