This design was based off a friends design which uses the flying machine to destroy pumpkins and push them into a hopper the main difference with my design is when the pistons/slime blocks reach the end of the path they come into contact with redstone and go back the other way in a loop. this was originally made on survival many years ago and is a design I am proud of the minecart track adds another layer since some of the pumpkins get pushed down the minecart with the dropper picks up the pumpkins when it gets pushed by the dispensers falling onto the track where it gets pushed off again. The place the minecart lands in the path of the moving repeaters has a dropper which the minecart puts any pumpkins it has collected into.
