The pulley is used to convert the hawos Rotare from hand-crank mode to anything that can attach to a pulley via a belt drive.
With a V-belt you can then drive the mill with a variety of options such as with electric/petrol engines, wind turbines, water wheels, modified bicycle etc. We have an electric motor for the hawos Rotare as well that can be used with this pulley.
Included is only the pulley.
The V-belt is not included as the length required is dependent on what you want to use the pulley with.
