6.17 HYDRAULICAL TRACK MARKERS
Track markers are placed at the frame’s ends and they are operated hydraulically.
To FOLD and UNFOLD the track markers, pressurize the hydraulic system.
In the case that the rst track marker to be unfolded is from the non-desired side, fold it and then
pressurize the system again. In this way, the track marker from the correct side will be unfolded.
Track markers can be adjusted in LENGTH and DISC ORIENTATION.
NEVER STAND UNDER THE TRACK DISCS OR WITHIN THEIR OPERATIONAL AREA..
IT IS ESSENTIAL TO FOLD THE TRACK MARKERS BEFORE FOLDING THE MACHINE FOR TRANSIT.
BEFORE FOLDING OR UNFOLDING THE TRACK MARKERS, MAKE SURE NO HIGH-VOLTAGE OVER-
HEAD LINES HANGING AT A LOW POSITION MAY TOUCH THEM. THIS MAY HAPPEN AS RESULT OF
THE ADJUSTMENTS PERFORMED TO THEM OR DUE TO THE TERRAIN’S CONDITIONS.
WATCH OUT WHEN FOLDING THE TRACK MARKERS. DEPENDING ON THE TYPE OF PLANTER AND
THE ADJUSTMENTS PERFORMED TO THE TRACK MARKER, IT MAY INTERFERE WITH THE FERTI-
LIZER HOPPERS. IN THIS CASE, EITHER THE LENGTH OR THE DISC ORIENTATION OF THE TRACK
MARKER NEEDS TO BE ADJUSTED.
6.17.1 ADJUSTING TRACK MARKER’S LENGTH
Track marker’s arms are extensi-
ble. To calculate the horizontal
spacing between track discs and
the last metering unit (B, Fig.
6.111), use following formula:
NOTA:
A= row spacing.
B= horizontal distance be-
tween track disc and the
last metering unit.
C=
track width of the tractor.
This adjustment allows you to keep the same row spacing A between a length with the planter
(1, Fig. 6.111) and its return (2, Fig. 6.111).
B=
A x (nº of rows + 1) - C
