I had that problem with a sandy driveway cut i compacted. Boy it sure does slow down the forward movement. I would make two or four sixty foot passes and then tilt it forward and scrape the bottom with a flat shovel. When I resumed the thing would practically run away from me.I got a rented plate compactor and like it for its ease of use. The only thing i noticed was in sand if you come across any clay it sticks to the bottom and then coats itself with sand. This slows the machine down and leaves groves. Its easy to fix scraping it off every now and then though. Alot easier than a jumping jack.
