After pushing a metal cube (or milk container on a square base) down the chute, how does the man move back into position without his arm interfering with the next one loaded to be pushed? Any helpful descriptions, photos, or videos would be appreciated. Thank you. I've owned and operated many of the great accessories Flyer provided us to enjoy, but not yet a 770. Thank you.

Here is a youtube video I found. Looks like next block is held back by the end of the guy's extended hand.
Thanks. I've seen that one and I agree it looks as though his arm holds back the next metal cube. Getting stuck sometimes in the process. There's also this video (see link below) where it looks as though his arm drags across the top of the next cube and then drops down behind it once he's all the way back into his starting position. I'm not sure either are the way it's supposed to work b/c the 770 was sold with either die-cast metal "boxes" or cubes or metal milk cans on square metal bases. His extended hand might be able to hold back a milk can as well as a cube, but not drag across the top of a milk can. Both videos were posted by the same person on 2/15/10. Maybe he was experimenting? Or maybe the man's extended hand is the answer.

One of the photos in this eBay listing shows where the man is forward and the exit panel at the end of the chute is down, so maybe the man only travels half the width of a box when ejecting one and his extended hand is what retains the next one until he get all the way back to his starting position. You'll also see a photo of boxes and milk cans. The milk cans might be large enough in diameter for his hand to make solid contact with one and also for it to touch the next one on the rack to prevent it from tipping or leaning over? Let me know what you think. Thanks.
Think you are correct - milk can diameter probably would allow to work. Looks like milk cans have a square bottom glued to them - probably homemade where the square bottom is same size as a box, allowing milk can to work correctly in spring loaded feed ramp, and slide down ramp, without tipping or jamming.
770's came with either metal cubes ("boxes") or square-based milk cans. The milk cans came from Gilbert with square metal bases on them. In fact, the 770 Instruction sheet features a photo of a 770 with a square-based milk can loaded in place ready to go.
