The down-pressure regulating valve kit replaces the two "T" fittings, in the middle of the cart, joining together hoses
from the toolbar cylinders.
CAUTION:
DO NOT ride on machine to adjust down-pressure or you could fall off
1
and be run over resulting in severe injury or death.
NOTE: This down-pressure regulating valve kit is for use with tractors with closed center hydraulics only.
NOTE: MUST have gauge wheels on toolbar.
NOTE: This hydraulic system does not compensate for conditions varying from soft to hard as you travel through the
field.
When adjusting active hydraulic down-pressure it is important to remember the following:
-
Seed depth is largely controlled by coulter depth when using a coulter cart.
The active hydraulic down-pressure system keeps the toolbar gauge wheels in contact with the soil surface
-
as the ground contour changes.
The amount of down-pressure required depends upon soil hardness, moisture and residue cover.
-
The recommended initial setting is between 400 and 600 psi.
-
IMPORTANT: Excessive down-pressure can increase wear, increase draft loads, decrease effective seed depth and
reduce gauge wheel bearing life. Use only as much pressure as necessary to achieve consistent operating
depth.
