Hydraulic Down Pressure
1
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 yoru
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.
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 ini-
tial 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 pres-
sure. If pressure is unneeded, move valve in
tractor to “FLOAT”.
Tillage Gang Controls
Your Turbo-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.
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.
