Bleeding Transport Lift Hydraulics
1.
Check hydraulic fluid level in tractor reservoir and fill to
proper level. Add fluid to system as needed.
2. With drill lowered into field position, loosen base-end-
hose fitting at elbow on right-hand transport-lift cylin-
der (1). See Figure 1-7.
3. Slowly supply oil to base end of transport-lift cylinders
until oil appears at the loosened hose fitting. As oil ap-
pears at fitting, tighten that fitting.
4. Completely extend transport-lift cylinders and imme-
diately lock cylinders up by flipping up cylinder lock
channels on both transport-lift cylinders. Refer to Fig-
ure 2-4, page 14.
The hydraulics could fail, causing the openers to fall and crush
you. To prevent serious injury or death, always secure cylinder
lock channels over extended transport-lift cylinders before
working under openers.
5. When cylinder lock channels are in place, loosen rod-
end-hose fitting at elbow on left transport-lift cylinder
(2). See Figure 1-7.
6. Slowly supply oil to rod end of transport-lift cylinders
until oil appears at loosened hose fitting. As oil begins
to appear at fitting, tighten that fitting.
7. Extend transport-lift cylinders and remove cylinder
lock channels. Completely cycle transport-lift hydrau-
lics several times.
Bleeding Marker Hydraulics
You may be injured if hit by a folding or unfolding marker.
Markers may fall quickly and unexpectedly if the hydraulics fail.
Never allow anyone near the drill when folding or unfolding
markers.
1. Make sure tractor hydraulic reservoir is full.
2. With markers unfolded in field position, crack hydrau-
lic-hose fittings at base and rod ends of each marker
cylinder.
3. With tractor at idle speed, activate tractor hydraulic
valve forward until oil appears at one fitting. When oil
begins to seep out around a fitting, tighten that fitting.
Reverse the tractor hydraulic valve until oil appears at
opposite hose fitting and tighten that fitting.
4. If you have dual markers, activate your tractor hydrau-
lic valve forward again until oil seeps out around one
fitting on the other marker cylinder and tighten that fit-
ting. Reverse tractor hydraulic valve until oil seeps out
around remaining hose fitting and tighten it.
5. Fold and unfold markers slowly to work out all air. Use
caution when folding and unfolding markers for the
first time, checking for pinching and kinking of hoses.
