Hydraulic Down Pressure
1. Engage the hydraulics (continuous flow) down.
2. From the cab, adjust the flow so the needle on the bypass gauge is in the green zone (1000 - 1500 PSI).
3. At the valve (1), adjust the valve to set your initial down pressure (usually 300-400 PSI). Do not exceed 800 PSI.
4. If the wings run high during operation, increase pressure. If the center runs high, decrease pressure. If pressure is unneeded,
move valve in tractor to “FLOAT”.
Tillage Gang Controls
Your Terra Max’s gang angles are hydraulically adjustable
from within a tractor cab. Simply determine the desired angle
and apply hydraulics until satisfied with the result. Angling
your machine’s tillage gangs can help breakup and level
difficult-to-work soil and root systems. For softer soil and final
passes when planting, set gangs to a vertical (non-angled)
position.

NOTE: Setting Gang Angles
Setting the gang angles to a more severe angle
allows disks to breakdown and circulate more crop
residue to the soil surface with fewer passes.
When gangs are angled, operating speed should be lowered to
between 9-12 kph to reduce machine stress and chance of disk
breakage. After returning the gangs to a vertical position, you
can resume normal operating speeds.
Turn off down pressure to wings while gangs are angled.
Resume applying down pressure when disks are returned to a
vertical position.
CAUTION: Field Hazard
Down pressure applied to wings while gangs are angled
causes overly aggressive and uneven tilling of soil.

When operating machine with blades in angled position, it is
generally unnecessary to apply wing down pressure. Only in
very hard ground will wing down pressure be necessary.
When not operating with live down pressure the fold system
must be in “FLOAT” position. Failure to operate either float or
active down pressure will damage the fold system. See your
tractor operator’s manual to set system to “FLOAT” position if
necessary.
This machine is designed for continuous hydraulic flow to the wing
fold cylinders during field operations. It is for use on tractors
having CLOSED CENTER hydraulics only.
