Fantastic unit for large yards. Mine is uneven and it does a great job. For really wet leaves I’ve put it in neutral and pull it backwards – does a great job. This also helps prevent the the front chute from hitting the ground when it is set low. Would purchase again in without a doubt. The bag is sturdy and easily withstands pulling mulched leaves out with a flat shovel. If the leaves are really wet or you are chipping a lot, the unit does tip easily, but that’s easy to feel when you are reaching the limit after a couple uses.
