Operating and Maintenance
Prior to 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. 
 
3. Hitch the tractor to the Discovator using the 
block or yoke clevis determined by the tractor 
drawbar. Use the correct size pin for clevis or 
block. 
 
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. 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. 
 
6. 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. 
 
7. After the machine is completely unfolded, 
raise and lower the Discovator several times 
to purge air from the hydraulic system. Again 
check for hydraulic leaks and tighten or 
replace if necessary. 
 
8. Check safety chain hookup. Make sure all 
warning lights are hooked up and functioning 
correctly. 
 
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. 
Always use the transport pins when moving 
from field to field. You are now ready to go to 
the field. 
First Time Machine Setup and Adjustments:
 
1. Pre-leveling of machine can be done on a 
concrete slab or good level surface. Lower 
machine so sweeps are 2-3” 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.) Level 
machine with the front row shanks just slightly 
deeper or lower than the back.
