With the adoption of the three-point linkage as the ‘standard’ way of attaching machinery to tractors, many of the first implements built to utilise this system were adaptations of trailed equipment – that had been towed via the tractor’s drawbar, or horses.
Even the big companies, like The International Harvester Company of Great Britain, saw modifying trailed equipment as a simple solution in the short term. Its ploughs were no exception and the first of the company’s mounted models had a remarkable resemblance to the B-8-A.
With the drawbar removed, and a headstock and suitable bracing added, the trailed plough was now the B-200 and B-300 – with a choice of 10in, 11in, and 12in furrow widths and initially three bodies (ACE, MPB10, and HFP – for general purpose, shallow, and deep work respectively).
Latterly, two other body types could be specified – the W10, short semidigger, and REX – like the W10 but producing more broken work – and there was also the option of ordering an IH plough to suit a particular tractor marque. Kits were available
