We have an Overton 125 wheelie bin type and a tecumseh engine centurion hybrid four wheeler with a wander hose, and mulcher.
The latter is better for leaves being quicker and not being able to suck up hidden bottles and cans when in push node.
The Overton is great when used with homemade adaptors to fit various specialised jobs- paddock and events- for any size bin. Straight to bag is useful but replacement hose is expensive.
Trouberl with using a 4 stroke and a two stroke is operator awareness.
