Ace advertises that their pullers are slow. I think (don't quote me on this) that ace pulls about 100 feet in 1 minute. You can expect 400 ft in 4 - 5 minutes. My friend has a gas puller and he was about to go A.D.D. waiting for the pot to come up. He said that the Ace being completely hands free makes up for it though.

On some Canadian forum's I browsed the crazy Canucks had gotten ticked off at how slow the Ace puller's are and installed heavy duty motors with gear ratio's to get the pots up quicker. They even had details telling how they did it.
