About Us

Joseph Brock (1922-1993) farmed 300 acres at Woodhams Farm, where we still are based today. As a mechanically-minded primarily arable farmer, some of the quieter time in the ’50s and ’60s he spent in the buying, refurbishing and selling of farm machinery along with the help of his staff. At that time he specialised in Minneapolis Molines balers and steel tracked crawlers, and also patented a sugar beet lifting device. This activity naturally grew as his sons began to join the firm, hence in 1978 ‘J Brock & Sons’ was established as a farm machinery business.

The 3 sons, Philip, Stuart and Mark grew the family business over the subsequent years, and in 2005 Stuart started the ‘Wheel and Tyre Department’ which in 2012 became a separate company, Brocks Wheel & Tyre Ltd, often known as BWT, also trading from Woodhams Farm. Later, in 2013, Mark started trading in tractors and farm machinery separately under the name of Oakfields, which was based at Nuthampstead, near Royston. 

In May, 2023, Oakfields and J.Brock & Sons joined forces, and Oakfields has become the primary used machinery business, also operating from Woodhams Farm. They supply a wide range of tractors and cultivation equipment, alongside selected plant equipment. The new Brock-Ag machinery which was started by Philip, and the Czech-based Farmet machinery are also available through Oakfields.

All our companies share the same values and ethos and remain true to the history that has gained us a good reputation. Together we look forward to helping you grow!
