Dowdeswell DP7 letters

[Bealy]

Hi, does anyone know what the different letters assigned to the dp7 mean, particularly the difference between an E and an F?
Thanks

From memory Dp7 D was a 4 furrow plough, E a 5 furrow and F a 6th furrow. I was there on student placement in '96/7 and could never fully get my head around the DP7numbering. Paul Wilkinson would be your man and there is a Dowdeswell group on facebook where he posts regularly.

a D was a 4 fr ,,E I think was 4+1 and an F is a 6+1

I think the first two numbers are year of manufacture, second two furrow width and third two point to point clearance, hence high clearance or not. But might be wrong

What does high clearance mean?

What does high clearance mean?

The vertical distance from the ploughs beam to the ploughs point, ideal in high trash situations

Ah that makes more sense. I thought it meant high clearance when turning on the headland. I was think they must have been ploughing in some wild conditions.
