Operating and Maintenance
Proper servicing and maintenance is the key to the long life of all farm equipment. With careful and
systematic inspection of your Ultra-till, you can avoid costly maintenance downtime and repair.
Adjustments Before Going to the Field:
1. IMPORTANT!! If you have not thoroughly
read and understood the safety section at the
front of this manual, do so at this time. DO
NOT proceed without fully understanding the
safety considerations of this machine.
2. Make sure your tractor horsepower matches
the implement you are pulling. This is
important so the implement can do the best
possible job. (Minimum of 7-8 HP per Ft.)
3. Hitch the tractor to the Ultra-till. This tool is
equipped with a reversible single tang hitch.
Use the correct size hitch pin to insure proper
performance and to minimize wear. Raise
any 3-pt arms and/or hitch attachments to
its fully raised position to clear implement.
4. For TWO-WHEEL DRIVE and MFWD
tractors, pin drawbar in fixed center position
for field and transport. For FOUR-WHEEL
DRIVE and TRAC-DRIVE tractors, leave
one hole clearance on each side of
drawbar for field position, hitch damage
may occur if pinned solid. Pin in center
position for transport to maintain
maximum steering control.
5. Check safety chain to insure that it is properly
attached. Make sure all warning lights are
hooked up and functioning correctly.
6. 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 or retracting.
A. Red – Disc Gangs.
B. Green – Fold/Hydraulic Down Pressure
C. Black – Main Lift.
7. 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.
8. After the machine is completely unfolded,
raise and lower the Ultra-till several times to
purge air from the hydraulic system. Again
check for hydraulic leaks and tighten or
replace if necessary.
9. Check the tire pressure for proper inflation
and check the tightness of the lug bolts and
lug nuts. See tire inflation chart in the
appendix section of this manual.
10. Check for any bolts that may need tightened
or retightened. Grease all the hinge points.
The hubs come pre-greased and will not need
more grease at this time.
11. Put transport lock in place and refold the
machine slowly. Put wing stop pins in place.
You are now ready to go to the field. (It is
very important not to run the machine
down the road without the transport locks
in place.)
12. Leveling the unit: You can adjust the side to
side levelness of the unit best before you
install the modules.
a). On a good level surface, lower the machine until
the cylinders are completely retracted and measure
down from the bottom of the center frame to the
ground. (Take note of this measurement.)
b). Repeat this process at each section to pre-
level the machine adjusting the eyebolt on
each cylinder.
13. Front to rear leveling should be done in the
field with modules installed. This is adjusted
with the turnbuckle on the hitch.
