Quadcopter mower

I did find a mower thread on here but it was about for automating riding lawn mowers. I am looking at building a quadcopter mower but am unfamiliar with the motors props and batteries needed to lift the quad components plus the motor for the blade(weight unknown) and the blade(roughly 2lb) If any one has any experience in relatively high payload quads and can recommend components that will work I would greatly appreciate it. Thanks.
