SETTING THE SEED DEPTH
SET UP THE SKI BOARD
The Ski Boards should be set up to drag along the top of the ridges with little down pressure. The down
pressure can either be increased or decreased by altering the adjuster at the rear of the drill
(3)
. The Ski
Boards are designed to level the ridges created from the leading tine and not to perform any kind of pressing
operation. The Boards should not be set at too steep an angle and should have the appearance of skiing along
the surface. The harrow tines may also be fitted to follow behind the Ski Boards or used as an alternative
depending on the machine specification.

A quick guide to correct drilling depth is to check the A-Shares relative to the soils surface. The diagram
below displays the recommended A-Share (2) depth for Oilseed rape (shoulder of A-Share should coincide
with soils surface) and Wheat (top of A-Share should coincide with ground surface).
