Launched in 1983, the Dowdeswell DP7 ‘auto turnover’ plough remained in production through to 2008. The fixed-width DP7 was supposed to be superseded, first by the mechanical vari-width DF120 and then the successor hydraulic or manual vari-width DF140, produced between 1992-2004 and 2000-2009 respectively. But such was the popularity of the DP7 it didn’t quite happen that way, sales only tailing off in the last couple of years of production. This means there are plenty of used DP7s still available
