Photograph and papers courtesy of Jim Christie, Crook of Devon.
This photograph shows the latest modified Deep Draining Plough with hydraulic controlled depth adjuster and single right hand throw mould board. As shown in the PDF the photograph was originally held by Bill Anderson Plant and Transport Manager for FC Scotland in 1971.
The PDF also includes the work study report by DM Hughes in 1968 and details the costs in shillings and pence with measurements in chains! Note also the PDF contains Mechanical Plant Specification as used when ordering replicate or alternative variants.
Any stories of working with these ploughs would be very welcome.
