Understand Active Hydraulic Rolling Basket Down-Pressure System
IMPORTANT:

A - Gauge Needle
Active hydraulic rolling basket down-pressure systems are
designed to be operated with closed-center tractor hydraulic systems
(tractors with load sensing or pressure on demand hydraulics are classified
as closed-center systems).Fixed hydraulic rolling basket
down-pressure can be achieved if tractor is equipped with open-center
hydraulics system, by operating SCV in NEUTRAL and manually recharging
system when rolling baskets do not operate properly due to hard ground
or hitting an obstruction.
Attempting to operate with active hydraulic rolling basket down-pressure
and an open center hydraulic system could result in permanent tractor
pump damage. See your John Deere dealer for more information.
CAUTION: Never adjust rolling basket down-pressure while machine
is in motion or serious injury or death may occur. Always lower machine
and stop tractor before adjusting.
IMPORTANT: Too much down-pressure can lift rear of machine,
causing it to become unlevel and resulting in uneven field finish.
The rolling baskets can be operated in the disengaged (raised)
position or engaged (lowered) position. Operating down-pressure is
set by adjusting the inside hydraulic valve located on the front of
the machine and making use of continuous hydraulic pressure. In most
conditions, operating in float or with minimal pressure is needed
to achieve proper field finish. In hard soil and dry residue, more
pressure may be needed to size clods; in soft or moist soil, less
pressure may be needed to size clods.
When adjusting active hydraulic down-pressure, it is important
to keep the following in mind:
-
Ideal initial pressure setting is with gauge needle (A) in 8
o'clock position or in float.
-
An active hydraulic system allows rolling baskets to raise up
when they strike an object in order to prevent damage to machine.
-
The amount of down-pressure needed to keep proper rolling basket
operation depends upon soil hardness, moisture and residue cover.
-
Too much down-pressure may result in machine front diving, causing
ridges on the outer edges.
-
Do not use more down-pressure than necessary to achieve proper
field finish.
