This section is intended to provide background information on the range of ploughs produced by David Brown to complement their tractors. All the information below was provided by DBTC member “Powerrabbit" and we are vey grateful to him for the contribution.
The section is very much “in preparation" at the moment and it is hoped to add more information particularly photographs as and when they become available.
Plough Designation and Serial Numbers
The brass plate attached to either the headstock or frame of the ploughs carries the ‘designation’, how the plough is made up, various types of bodies, coulters etc and also the serial number.
The first letters on the plate identify the type/series of plough, e.g. PU. BE. BH. C. CM. CW. CMR. CWR. DM (additionally for the C type, “W" = wide and “R" = reversible).
The next set will tell you how the plough is made up and with what type of components.
