Adjusting the plough
27
Set-up
The figures above show a simplified set-up (simple crown) which
requires minimal adjustment. With the plough set for normal
ploughing, the crown is driven without any setting other than the
variation of the depth (hydraulic pack and depth wheel).
First pass (A): Only the three plough bodies are ploughing. The
rear body ploughs at approx. 1/2 depth.
Second pass (B): Driven in the opposite direction, with the tractor's
left-hand wheel in the empty furrow. The front plough body is at ap-
prox. half depth and the rear is at full depth.
Third pass (C): The tractor's right-hand wheel is driven in the first
furrow from the second pass. The front plough body is at approx.
half depth so that the crown is sufficiently high.
