Field Adjustments & General Operation Instructions
1. The Ultra-till is designed as a primary/
secondary vertical tillage tool and is designed
to leave a finished seedbed following some
form of fall or spring tillage. In a min-till/no till
operation, it may be used as a primary one-
pass vertical tillage tool. For best results, if at
all possible, run the machine at a slight angle
to the rows. This will improve trash flow and
help spread the residue more evenly
throughout the field.
2. The ideal working speed for turbo blades is 7
to 10 MPH. If the Ultra-till is equipped with
disc-blades, then no more than 7 MPH is
recommended due to the possibility of ridging.
3. Before starting in the field: Set the depth of the
gangs at 0 inches on the gauge. Let the
machine all the way down until the cylinders
are retracted. Set your leveling front to back
with the turnbuckle on the hitch by lengthening
or shortening. Re-set the depth of gangs
between 2 to 3 on the gauge.
4. Set the hydraulic down pressure using the
instructions provided on pages 28 & 29.
5.
Caution: Never leave tractor valve
centered when unfolded with
machine in motion
. Machine damage
may occur when wings flex. The hydraulic
down pressure cylinders have no wing flex
capability and oil flow is required when the
wings flex up or down. You must have the
tractor fold hydraulic lever in continuous
downward flow or “float” position before
the wings can flex over terrain in the raised
or lowered lift position.
6. If possible, have someone observe the
machine during first time operation for
levelness – front to rear and wings to center
frame. Adjust each as needed. If ground is
soft, and the blades are running too deep,
raise the gangs to desired depth. You may
need to readjust front to back. If the ground is
hard this may raise the front and again the
front to back may need to be changed (Note:
To change front to rear, either extend to raise
the front, or shorten the turnbuckle to lower
front.) On 5-section Ultra-tills with the
hydraulic gauge wheels, set the wheels in field
position to be 1” to 2” off the ground.
7. For a final adjustment on the hydraulic down
pressure, note the action of the gang bolts as
the machine operates through the field by
watching the nuts at the top of the bolts (as
shown by arrows). If the center gang bolts are
more active than the wings, the pressure to the
wings may need to be increased. If the wing
gang bolts are cycling extensively but the
center is not, the pressure to the wings needs
to be decreased. On a five-section machine,
you need to set the outside wings with one
valve and the inside wings with the other (the
valves are marked as to which is which). Once
you have all the spring bolts across the
machine working evenly, lock the valves in
place. You may need to re-adjust these valves
as field conditions change, (i.e. ground
becomes harder as it dries out or wetter after a
rain).
8. If a basket is added for leveling, use the
eyebolt to increase or decrease down
pressure. (Note: Shorten for less pressure or
lengthen for more.)
