{{Main|Mill machinery}}

Gears inside a windmill convey power from the rotary motion of the sails to a mechanical device. The sails are carried on the horizontal windshaft. Windshafts can be wholly made of wood, wood with a cast iron pole end (where the sails are mounted), or entirely of cast iron. The brake wheel is fitted onto the windshaft between the front and rear bearings. It has the brake around the outside of the rim and teeth in the side of the rim which drives the horizontal gearwheel called wallower on the top end of the vertical upright shaft. In [[grist mill]]s, the great spur wheel, lower down the upright shaft, drives one or more stone nuts on the shafts driving each [[millstone]]. Post mills sometimes have a head and/or tail wheel driving the stone nuts directly, instead of the spur gear arrangement. Additional gear wheels drive a sack hoist or other machinery.
The machinery differs if the windmill is used for other applications than milling grain. A [[windpump|drainage mill]] uses another set of gear wheels on the bottom end of the upright shaft to drive a scoop wheel or [[Archimedes' screw]]. [[Sawmill]]s uses a crankshaft to provide a reciprocating motion to the saws. Windmills have been used to power many other industrial processes, including [[papermill]]s, [[threshing]] mills, and to process oil seeds, wool, paints, and stone products.<ref name="ReferenceA">Gregory, R.
