Poor turnout for weed clearing work party, but 3 dedicated members did turn out, and using the Neptune Weed Rake they cleared some weed. Hard work from these guys. Well done. Quite impressive bit of kit.
Pretty much as you said. Engine in powering a pulley to retrieve the rake. However drones do not record sound as all you would hear is the propellers. All sound added in editing for effect and may not represent the true sound of the motor.
