Bought a Snapper P2160KWV Self-Propelled Mower for an experiment. Needed a side discharge 21" mower. Got this for $699. The commercial one was $899. This is a residential model but I think the only difference between the commercial model and this is steel wheels. This model has plastic wheels, if they break I will replace them with the steel ones. Has a steeel deck. Came with Ninja mulching blade, mulching plug, side discharge cover, discharge chute and bag. I do like the Kaw FJ180V motor. Anyone had one of these mowers?
