Powerworks 21 Inch 40V Lithium Self-Propelled Mower, 5 Ah Battery and Charger Included PD40LM51SPK5 http://www.samsclub.com/sams/a/prod22041919.ip
I found out that this powerworks is exact design of greenworks and share the same battery design. That mean cross over compatible with gmax 40v battery.
If you are on the mover market with look for self propelled version. This choice is not bad.
