Gressenhall harvest (Albion 5a reaper binder)

16th August 2016. Harvest time at Gressenhall Farm and Workhouse museum. Information from the museum website: The reaper binder does not only cut the crop but also binds it into sheaves. The cut stems fall onto a bed canvas, which then transports it to two other elevator canvases which nip the harvested crop together whilst moving it to the binding mechanism. The binding mechanism bundles the crop and ties a piece of twine around the bundle. Once tied, it is ejected from the side of the binder. Our binder is an Albion 5a and dates back to the 1940’s. It was produced by The Harrison McGregor Works at Leigh who were established in 1873 by Henry Harrison and Alexander McGregor. The ‘Albion’ range or harvest machinery achieved high sales and a high reputation around the world. The binder is designed to be horse-drawn, but can be adapted for use with a tractor. The main drive of the machine is produced by a ‘bull wheel’ or ‘land wheel’. When the wheel turns, it drives a chain which then drives a gear box that transmits its power down driveshafts to make all aspects of the binder work. The earliest models of binders used wire because the tying of the sheaf could be made with a simple twist rather than a complicated knot. But this did prove to have some disadvantages: it made it more difficult to cut the wire tie, and there was always the risk of damage through pieces of wire slipping through to the mechanism of a threshing machine. The automatic knotting (binding) mechanism for twine was developed in America during the 1860s. Binders using the device did not immediately become popular because the twine used was relatively scarce and costly. This changed during the 1880s as the volume of production in Mexico of twine, made from sisal hemp, became available. This meant that the twine tying binders quickly took over from the wire variety.
