7.14.1 - Points menu
7.14.1.1 - General
This function is used to automatically modify the furrow
start and end lengths according to the shape of the field.
Furrow starts and ends are therefore always rectilinear. For
this purpose, the length of the points must be stored (A and
B Fig. 212). This corresponds to the difference in length (for
example A or B) in relation to the width of work.
When using a semi-mounted plough, for example, the
DUAL CONTROL ensures that the exit or entry of the last
share occurs at the same position as the first share (Y Fig.
213). In the case of a negative point value (B Fig. 212), the
furrow end length is automatically extended. The opposite
applies for a positive point length. The purpose is to per-
form straight furrow ends, whatever the shape of the field.
NOTE: This function is only used with the FRONT or
REAR DUAL CONTROL.
