My only experience is keeping the neighbors 'pull-behind' running for him. He goes too fast and his pull-behind wasn't designed for 'heavy' use. After several modifications, including beefing up the frame and the wheel axles, finally have a unit that seems to take the abuse. I prefer the 3pt variety, and like the unit closer to me, rather than stirring up things that can fly 'way out there', outside my comfort zone.
