Hydraulic System

Adjusting The Hydraulics

1. Be sure tractor hydraulic reservoir is full.

2. With the markers in ﬁeld position, crack the hydraulics hose ﬁttings located at the base end of one of the cylinders. With the tractor at an idle speed, activate the tractor hydraulics valve until hydraulicoilseeps outaround thehose end.Tighten the hose end ﬁttings. Repeat this process for the hose at the rod end of the cylinder.Crackthe ﬁttings on the back side of the sequence valve until hydraulic oil seeps out. Tighten and repeat for the opposite cylinder.

3. Cycle each cylinder 3 or 4 times slowly. Both arms shouldmoveto the verticalpositionon theﬁrstmove and then they should lower and raise alternately as the hydraulic lever is operated.

4. Foldandunfoldthemarker(s) slowlyin order towork all theairoutofyourmarker hydraulics.Use caution when folding and unfolding the marker for the ﬁrst time, and check for pinching and kinking of hoses.

CAUTION

Never allow anyone near the drill when cycling the markers.

Hydraulic System

CAUTION

Excessive folding speeds can cause marker damage!

CAUTION

Escaping Fluid under pressure can have sufﬁcient force to penetrate the skin. Check all hydraulic lines and hoses before applying pressure. Fluid escaping from a very small hole can be almost invisible. Use paper or cardboard, not body parts, to check for suspected leaks. If injured, seek medical assistance from a doctor that is familiar with this type of injury.Foreign ﬂuids in the tissue must be surgicallyremoved within a few hours or gangrene will result.

General Notes

The markers cycle in the following sequence

(1)Right Up, Left Up (2)Right Down, Left Up (3)Right Up, Left Up (4)Right Up, Left Down (5)Sequence Repeats

5. The marker hydraulic system is equipped with needle valves to control how fast each marker operates. The needle valves are built into the sequencevalvebody.Therearetwo hexadjustment heads, one for raising the markers, and one for lowering the markers. These are stamped in the valve body. To adjust the speed of each marker, screwthe needle valveclockwise to adjust the raise or lower marker speed to a low setting. Fold the marker up and down a few times and recheck for pinching and kinking of hoses. With the tractor engine at an operating rpm, adjust the needle valve to limit the marker to a safe operating speed. Excessive folding speeds can cause marker damage.

NOTE: JIC fittings do not require high torque. JIC and ORingfittings do not require sealant. Alwaysuse liquid pipe sealant when adding or replacing pipe thread fittings. To avoid possible danger of cracking hydraulic fittings from over tightening,

DO NOT use plastic sealant tape.

Maintenance and Lubrication

Maintenance

Proper servicing and adjustment is the key to the long life of any farm implement. With careful and systematic inspection, you can avoidcostly maintenance, time and repair.

Breakaway Pr otection

The marker arm is attached to the marker body with a 7/16" breakaway bolt. If excessive force is put on the markerduring operation,theboltwillbreak,allowingthe marker arm to swing away rather than cause damage to the marker.

NOTE: The breakaway bolt is a 7/16"-14 x 2 1/4" long grade 5 (G.P. # 802-234C). It is identified as a grade 5 by having three marks on the head. If it breaks, it must be replaced by an equivalent grade 5 bolt to prevent marker damage.

Hydraulic marker functioning improperly

Check all hose ﬁttings and connections for air and oil leaks. The chain on the folding marker should be slack when the marker is both fully extended

and fully raised. Check tractor hydraulic oil level. Check all bolts and fasteners. If needle valve is plugged; open valve, cycle markers, and reset the needle valve. Double selector valve positioned for fold cylinders. Shift valve to marker sequence posi-

tion. The marker folding linkage and chain must have enough slack to allow the marker disk to

drop down into depression in the ﬁeld. Maximum down ﬂoat should be limited by the slots at the rod end of the marker cylinder, and not by the chain. Read the adjustments section of this manual when adding slack to chain.

The blade may be reversed to pull dirt in or throw dirt out depending on soil conditions. An optional smooth blade is available through your Great Plains dealer. The notch blade

comes with your marker as standard equipment. Check all hose ﬁttings and connections for air and oil leaks. The chain on the folding marker should be slack when the marker is both fully extended
