Operating and Maintenance
Prior to Going to the Field
1. Both dealer and customer read and
thoroughly understand all safety
recommendations. (These are found in the
Safety Section of this operator manual.)
2. Make sure your tractor horsepower matches
the implement you are pulling. This is
important so the implement can do the best
possible job. Ground speed in normal
conditions range from 6 to 8 MPH.
3. Hitch the tractor to the Turbo Till using a
tractor drawbar arrangement compatible with
a category III perfect hitch system. Use the
correct size pin for the drawbar and clevis.
4. Clean all hydraulic couplings and connect to
tractor. Each hydraulic coupling has a colored
handle on it and is marked with a cylinder,
either extending (black) or retracting (red).
5. If machine is folded, remove the transport pins
from the wing stops. (Do not remove pins if
the wing is leaning against the pins or putting
pressure on the pins. Use the hydraulics to
pull the wings in completely before unpinning
them.) Once the pins are removed, slowly
unfold the unit. Make sure no one is under
the wings during the unfolding process.
Check again for hydraulic leaks and watch
that hoses do not get pinched in hinges, wings
stops, etc.
6. After the machine is completely unfolded,
raise and lower the Turbo Till several times to
purge air from the hydraulic system. Again
check for hydraulic leaks and tighten or
replace if necessary.
7. Pre-leveling of machine can be done on a
concrete slab or good level surface. Lower
machine so coulters are 1-2” off of ground on
the center frame. Adjust the turnbuckle
(Figure 1) at the front of machine to level it
from front to back. (Shorten to bring front
down, extend to bring front up.)
Figure 1
8. Set the wings to match the depth of the
center. This is done by adjusting the lift
turnbuckle on each wing (Figure 2). Shorten
the turnbuckle to run shallower, lengthen the
turnbuckle to run deeper.
Figure 2
Wing leveling can be affected by the hydraulic
down pressure feature. If wings are running
too high increase hydraulic down pressure
setting, Too low, decrease down pressure
setting. See Section 2: Hydraulics for initial
setup and operation.
9. Check safety chain hookup. Made sure all
warning lights are hooked up and functioning
correctly.
10. Check the tire pressure for proper inflation
and check the tightness of the lug bolts. Tire
pressure amounts are located on the sidewall
of each tire and in the appendix.
