7.ADJUSTING SEED PLANTING DEPTH
Seed drill should always work horizontally, with both the rear and frontal
tine coulters equally penetrating the land.
MUY IMPORTANTE: The tractor's controller that moves the folding parts'
cylinder must be in FLOTATION mode, to better adapt to the ground.
7.1 ADJUSTING RATCHETS AND SPINDLES
There are two ratchets (fig. 51) in the machine's central body and two spindles
in the side wheels (fig. 52). All of them have an adjusting scale to indicate
their position.
Their adjustment positions in the respective scales should be the same.
After adjustments, the control lever of the ratchet should be pulled back
towards the inner part of the machine.
When sowing on tilled or non-compact ground, take the precaution of se-
lecting one or two points lower in the adjusting scale on the side wheels in
order to avoid sinking into the ground.
