Section 2 Assembly Instructions & Set-UpBleeding theHydraulic Lifting SystemThe implement lifting system is equipped with rephasingtype hydraulic cylinders that require a special procedurefor bleeding air from the hydraulic circuits. Read and follow the procedure carefully. The rephasing type cylinders will not function properly with air in the hydrauliccircuit. Bleeding the system may have been done duringinitial set up of the drill.10123Hitch Height AdjustmentFigure 2-64. Connect the hitch to the tractor using a pin of adequate strength (minimum 1" diameter).Refer to Figure 2-7:5. Unpin the tongue jack, and pin it on top of thetongue.Jack In Transport PositionFigure 2-711833NOTE: Make sure the hitch is securely bolted to thedrill tongue.Your drill comes equipped with a hitch safety chain. Thesafety chain should be securely attached to the drill hitchand the tractor drawbar whenever towing or planting.Tractor Hydraulic Hook-UpRoute the lift hydraulic hoses along the tongue andthrough the hose loop on the front of the tongue. Connect the hoses to the tractor remote outlets.!1. Jack up and support the front member of the drill ata point close to each end wheel. If the end wheel cylinders have previously been engaged, they may beused to assist in raising the frame.2. With the frame blocked and supported, unpin thecylinders from the drill frame and turn the cylindersupside down and wire or otherwise safely supportthe rod end port higher than the base end port.3. With the tractor engine at an idle speed, hold the remote lever on to put fluid into the lifting circuit. Whenthe cylinders have completely extended, hold the remote lever on for one minute.4. Retract the cylinders. Extend the cylinders againand hold the remote lever on for one more minute.Repeat this step two more times to completely bleedthe system.5. Repin the cylinders to the drill frame, rod end to thewheel arm. If air is trapped in either cylinder, the affected cylinder will have a spongy, erratic movementand the drill will not raise evenly. Refill the tractor hydraulic fluid reservoir to its proper level.NOTE: After the drill is raised, a slight settling will occur due to the action of the rephasing cylinders.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 bealmost invisible. Use paper or cardboard, not body parts, tocheck for suspected leaks. If injured, seek medical assistancefrom a doctor that is familiar with this of injury. Foreign fluidsin the tissue must be surgically removed within a few hours organgrene will result.4/25/06NOTE: Check the hydraulic fluid in the tractor reservoir and fill to the proper level. Add fluid to the system as needed. A low reservoir level may draw airback into the system, causing jerky or uneven cylinder movements. The drill system capacity is approximately 1 gallon.Great Plains Mfg., Inc.IMPORTANT: When using sealant on pipe threads thefriction between the threads is reduced; therefore, becertain not to over tighten causing damage to the cylinder port or fitting.EWNT7 and EWNT10 End Wheel No Till Drill 150-082M-A-9

Section 3 Basic OperationSection 3 Basic OperationOperating theLifting Hydraulic SystemLock Out HubsBefore transporting the drill, you should always checkthe following items:The lift cylinders may after a period of time get out oftime or phase. The effects of this can be seen when oneside of the drill is running too low or too high because itslift cylinder is either overextended or overretracted compared to the other lift cylinder. To rephase the cylinders,raise the drill completely up and hold the tractor hydraulic lever on for a few seconds to give the cylinders time torephase. This should be done each time the drill israised out of the ground. Momentarily reversing the hydraulic lever immediately after rephasing to allow the cylinders to retract about 1/2" will help in maintaining a leveldrill.TransportingOperating Transport LockRefer to Figure 3-1:When transporting your drill, you should always lockyour drill in the raised position. Fully extend the lift cylinders to raise the drill for transporting. Remove the lockpins from the storage position, Figure 3-1. {One on eachside of the drill frame.}1. Make sure that drill is securely attached to the drawbar of the tractor and that the hitch safety chain hasbeen securely attached.2. Check to see that the transport tires have the properinflation as noted on page 6.Refer to Figure 3-3:3. Make sure the drive lockout hub (left side) is disengaged before transporting, see Figure 3-3. This willprotect from excessive wear on the gauge wheeldrive system.4. This drill comes equipped with a transport lock pinlocated on each side of the drill frame. Make surethe pin is in its transport position as shown inFigure 3-2.5. Comply with all federal, state and local safety lawswhen traveling on public roads.6. Remember, the drill is wider than the tractor and extreme care must be taken to allow for safe clearance.101511189010252Lock Pin In Field - Storage PositionFigure 3-1Refer to Figure 3-2:Place the lock pin through the frame channel as shownin Figure 3-2. Before lowering the drill, you must first extend the lift cylinders completely and move the lock pinsto their storage position.Drive Lock Out HubFigure 3-3!WARNING!This drill should never be pulled faster than 20 miles per hour.11838Lock Pin In Transport PositionFigure 3-210EWNT7 and EWNT10 End Wheel No Till Drill 150-082M-AGreat Plains Mfg., Inc.4/25/06

Section 4 AdjustmentsSection 4 AdjustmentsDrive System ClutchDrive Train OperationRefer to Figure 4-1:The main drive clutch (#1) on your drill is a mechanicalrelease - jaw style design which may require some adjustments before using your drill. Raise the drill to thetransport position. Check between the two cam plates(#2) which disengage the jaws (#3) & (#4) of the clutchhalves. The clutch jaws (#3) & (#4) should be completelyseparated at this point.Refer to Figure 4-2:Your grain drill uses standard no. 40 roller chain throughout its drive system. The drive system is simple and designed for low maintenance. All chain idlers should bechecked at the beginning of each season to insure thatthey are adjusted properly.Adjustments can be made to the cam plate (#6) by loosening the bolts, and nuts (#5) in the clutch tab(#7).Whenever adjusting the clutch, check to be sure theclutch jaws (#3) & (#4) are engaged completely whenthe drill is lowered to the field position. The clutch jaws(#3) & (#4) should also be completely disengaged whenthe drill is raised for transport.To do a maintenance inspection, simply check each idlerto insure that it is taking up any excess chain slack. Onfertilizer and native grass drills the inspection cover forthe drive is located on the outside of the left box end panel and this cover must be removed to inspect the fertilizerand native grass drive chain and idler.In the left wheel arm are two idler sprockets, Figure 4-2,which should be readjusted after the first 100 acres ofdrill use and then at the beginning of each season. Toadjust, move the front idler sprocket, on the top of thechain, down, by loosening the jam nut and screwing theadjustment stud in. Chain idlers should always be keptsnug against the slack side of the chain. Do not overtighten chains, it will cause excessive wear on idlers anddrive components. Retighten the jam nut to maintain theidler position.1011914018Jaw Clutch AdjustmentFigure 4-14/25/06Great Plains Mfg., Inc.Idler Sprocket AdjustmentsFigure 4-2EWNT7 and EWNT10 End Wheel No Till Drill 150-082M-A-11

Section 4 AdjustmentsSeeding RateCalibrating the seeding rate requires four steps: arranging the drive sprockets, setting the seed-rate handle, positioning the seed-cup door, and checking the seedingrate.Refer to the seed-rate charts starting on page 14. Thesecharts list the proper sprocket sizes and seed-rate-handle settings for various seeds and seeding rates.a. Pull spacers off shaft.b. Slide sprockets as necessary.c. Place plastic dividers back on shaft betweensprockets as necessary.5. Slide idlers on idler arms so they are aligned withcorrect sprockets. Reinstall chain.6. Turn idler arm as indicated by drive type to removeslack from chain. Retighten nut that holds idler arm.The seed-rate charts are based on cleaned, untreatedseed of average size and test weight. The rates arebased on 9.0 x 24 rib implement tires. Many factors willaffect seeding rates including foreign material, seedtreatment, seed size, field conditions, tire pressure andtest weight. Minor adjustments likely will be needed. Setand check the seeding rate using the procedures below,then adjust the rate as necessary.2133Change Drive SprocketsRefer to the seed-rate charts for the correct drive type–1, 1A, 2 or 2A. Figure 4-3 shows the sprocket arrangement for each drive type.Type 216475Sprocket BoxFigure 4-4Type 2ASet Seed-Rate HandleThe position the handle (shown in Figure 4-5) to the setting indicated on the chart. To adjust, loosen the wing nutunder the handle.
