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.
3. Hitch the tractor to the Field Cultivator using
the block or yoke clevis determined by the
tractor drawbar. Use the correct size pin for
clevis or block. 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. 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).
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 Field Cultivator several
times to purge air from the hydraulic system.
Again check for hydraulic leaks and tighten or
replace if necessary.
8. Pre-leveling of machine can be done on a
concrete slab or good level surface. Lower
machine so sweeps are 1-2” off of ground on
the center frame. Adjust the turnbuckles on
the front caster wheels (Figure 1) 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.
Figure 1
9. Set the wings to match the depth of the
center. This is done by adjusting the lift
cylinder eyebolt on each wing (see Figure 2).
Lengthen the bolt to run shallower, shorten
the bolt to run deeper.
Figure 2
In some conditions the wings will need to be
set slightly lower than the center as the center
may tend to run deeper behind the tractor
tires.
