do you want a light harness, full harness, a long use harness, or a simple strap?
Good question. This is for homeowner use, probably weekly during mowing season. I would think a simple strap, maybe with a padded section for the shoulder and neck. My 323L doesn't have a place to attach a strap, so I would need a clamp of some kind to attach to the shaft for the strap's hook.
Yeah, I would have thought that it would as well, but the only one on the sales floor with a strap was the model with the two handles (used more for brush cutting I think). Otherwise, strap and clip are a separate purchase.
