3.4. Assembly of dual disc steering set
with track rod
In the case of dual discs, the use of a
mechanical track rod is preferred (
Figure 17
and
Figure 18
) instead of an hydraulic track rod.
Take account of the working depth of the disc
and the position of the disc leg in the
attachment. The disc legs are provided with
multiple holes in order to finely adjust the
required working depth.
Construct a sturdy frame from thick-
walled tubing of at least 80 x 80 cm.
The track rod must be adjustable, by using a
spindle, to be sure that both discs can be
properly aligned. Cut the rod supplied in two
halves. Determine the desired length of the
track rod. Weld a tube between the two track
rod sections. Finally, in the straight forward
position, the discs should are parallel. Check
whether the distance between the discs at the
front and the rear is the same. If necessary,
make adjustments to the track rod.
Use the rod supplied to construct an
adjustable track rod.
On a retractable implement, the frame for the
disc legs can be mounted in a central position
on the beam of the main frame (
Figure 18
).
