pto hydraulic pump for planter free sample

�����HydraBoost is a closed center, pressure compensating system powered by a pto,� says Dan Symington, Command Hydraulics. �We can produce the higher pressure needed for down pressure and for other precision planting equipment, as well as for vacuum fans and more.�

����The company suggests that HydraBoost works with every tractor/planter combination on the market. It is available in multiple sizes, from 12 gpm to 40 gpm, and can be equipped with either 4 or 6 additional ports. Reservoir capacity ranges from 15 to 25 gal., depending on pump size. The kit also includes Command Hydraulics� PumpDoctor, designed initially for use with Case IH and Kinze planters.

�����PumpDoctor is an integral part of HydraBoost,� says Symington. �We also sell it by itself for use with other pto-powered hydraulic pumps. Anytime you put a pump directly on the pto, you tend to get vibration. Our double chain connection PumpDoctor cushions it.�

����The PumpDoctor is a support bracket that secures any pto pump directly to any tractor frame via a mounting plate. Without such a bracket, the pump hangs on the pto shaft. The weight causes excess vibration, shaft strain and warping or breakage. The PumpDoctor is available in 3 models for 16, 18 and 12-tooth sprockets.

����The tractor mounting plate is designed to match the exact bolt pattern for specific tractor models, ensuring a secure and tight fit. The PumpDoctor kit also includes sprockets, chain and hardware for mounting.

2 Air-Pro ® PTO Pump Table of Contents Index Great Plains Manufacturing, Inc.Using PTO SafelyThe accessories covered by this manual rely on PTOpower to operate, and require an adjustment at theplanter while the PTO is running. The PTO pump isdesigned to work on a stub shaft PTO, and leaves noexposed shaft in use.▲ Use only a tractor with an approved master shield for thePTO.▲ Use all guards provide for the tractor PTO. Have minimalor NO shaft exposed after connecting the PTO pump.▲ Use only a rear-facing PTO. The provided hoses and torquearms are not designed for use with a tractor-front ortractor-side PTO.▲ Use only a 540 rpm PTO, or an adjustable PTO set to540 rpm maximum. Running at a higher speed could resultin equipment failure, and serious injury.▲ Use only a PTO with the correct shaft:1 3 ⁄ 8 inch (35 mm) 6-spline.▲ Do not use an adaptor, extender or external gearbox.▲ Use only a “live” or “independent” PTO. If the PTO onlyoperates when the tractor is in motion, there is no safe wayto set the fan speed.▲ Ensure that all involved personnel are trained on PTOoperations and hazards. Always know where all teammembers are before, during and after PTO operations.▲ Allow only essential personnel near the PTO during setup,adjustment, operation and disconnection.▲ Prior to PTO setup, remove any stray wire, rope or twinefound nearby. Should a loose end encounter the PTO stub, itis taken up at over 7 feet per second, and could wraparound someone and pull them in.▲ Wear only snug-fitting clothes, with no scarfs, loose strings,cords or ties, and no frays, when working near a PTO.▲ Tie long hair back or gather it up under a well-secured hat.▲ Always shut the tractor off when making PTO connectionsor disconnections. Do not trust your life to clutches andthrow-outs.▲ A PTO shaft is a hazard at any speed, even when well belowrated shaft rpm, coasting to a stop, or idling.▲ Never step on or over the master shield or installed PTOpump.▲ Be extra vigilant if any tractor PTO controls are external,and in proximity to the PTO.▲ Elevate pump hose slack so that ground contact is notpossible during transport or field operations.▲ Keep all PTO safety decals clean and legible. Replace anythat are faded or damaged.CAUTIONTo avoid Injury orMachine Damage:*Operate only with540 rpm PTO818-130C Rev. B✔1.375 in35 mm401-885M Table of Contents Index 2013-03-04

Great Plains Manufacturing, Inc. Table of Contents Index PTO Operation 9Hitching with PTOThe pump may be installed before or after hitching theplanter to the tractor. With a 3-point planter, installing thepump first may be easier.Prepare Tractor1. Back the tractor into close proximity to the planter(within pump hose reach of the PTO shaft).2. Shut down the tractor and remove the key.2Entanglement and Crushing Hazard:Never perform any mechanical adjustment, PTO setup orhitching with the tractor running. Take no chances that thePTO might become active. Entanglement or flailing equipmentcan cause serious injury or death faster than you can react.Refer to Figure 43. Make any necessary adjustment to the tractordrawbar 1 . This might include:inverting an offset drawbar, and/orrelocating a clevis assembly (not shown).1Figure 4:Mount PTO Pump334620Entanglement and Flailing Equipment Hazards:Do not use a driveline, shaft extension, adaptor or externalgearbox with the PTO pump. Use the pump only on a native540 rpm 6-spline stub shaft. Extra fittings create entanglementhazards. Fittings also destabilize the shaft, and may make itimpossible to adequately secure the pump against torque andshaft slip.Mount Pump4. Clear the PTO shaft 2 of any pins or wires thatmight prevent the pump from fully seating on theshaft.5. With hydraulics hoses to rear, and torque arm 3 toright of drawbar, slide the pump assembly fully ontothe PTO shaft.Secure PumpRefer to Figure 5 (shown with pump off for clarity)6. With the torque arm firmly against the drawbar:loop the chain once 4 around the drawbar,then through the anchor point 5 ,then around the drawbar 1 at least once more,then through the keyhole slot 7 in the torque plate.The drawbar loops prevent pump rotation.The anchor loop retains the pump on the PTO shaft.5 467Figure 5:Route Pump Chain346222013-03-04 Table of Contents Index 401-885M

858-003C858-004C10 Air-Pro ® PTO Pump Table of Contents Index Great Plains Manufacturing, Inc.Refer to Figure 67. At least one full chain link must be exposed at theslot 7 on the decal side of the torque arm plate.If there are more than a few chain loops left at theplate keyhole, route any excess chain through theanchor point and/or around the drawbar.8. Do NOT use any pins, cross-bolts or wires to securethe pump to the PTO shaft. Such fasteners are notrequired for safe pump operation, and would add aneedless entanglement hazard.9. Pull and twist the pump assembly to verify that thechain is sufficiently taut to prevent excess pumprotation or sliding along the PTO shaft.10. Complete normal planter hitching.Check Hydraulics7DANGERROTATING DRIVELINE -CONTACT CAN CAUSE DEATHKEEP AWAY!DO NOT OPERATE WITHOUT-All driveline guards, tractorand equipment shields in placePTO pump assembly securely858-005Cattached with torque arm and chainCheck Oil LevelRefer to Figure 71.

Check that all hydraulic fittings are tight and dry.Inspect all hoses for damage, wear and fatigue.Because the PTO pump system is closed, anyvisible fluid may be an indication of a leak.Figure 7:Check Oil Level34625401-885M Table of Contents Index 2013-03-04

Great Plains Manufacturing, Inc. Table of Contents Index PTO Operation 11Starting the PumpWhile the planter is stationary, it may be necessary tobriefly operate the pump for any of several reasons:• verify system installation or PTO operation• verify oil level with system fully charged• set initial meter pressurizationRefer to Figure 81. If the system is adjusted, leave the flow controlvalve as-is.21If the system is not yet adjusted, close the flowcontrol valve to prevent fan motion. Turn the lockdisc 1 counter-clockwise to release the knob 2 .Turn the knob fully clockwise to close the valve.2. Clear the hitch area of non-essential persons.Check essential personnel for long hair, scarfs,cords, frays, loose flaps and anything else thatmight get entangled. Clear the area of dangling orloose wires, straps, cord and other lines that mightbecome entangled and pull someone in.3. It is not necessary to run the PTO at the full540 rpm. You may run it any speed that providessufficient meter pressurization (page 12).Figure 8:Flow Control ValveEntanglement and Crushing Hazard:Use extreme caution in the hitch area when the PTO isoperating.34626Equipment Damage Risk:Do not START the pump and fan suddenly at high PTO power.Engage the PTO clutch slowly (if possible) and/or at lowengine rpm, and gradually increase PTO rpm. The hydraulicfan can be damaged by sudden acceleration.4. • Check that tractor is in Park or Neutral.• Check parking brake set.• Set the tractor PTO controls for540 rpm gearing (if multi-speed) andclockwise rotation (if bidirectional).• Start tractor engine and set throttle to idle.• Engage the PTO.• Bring the tractor engine and PTO up to intendedfield rpms.5. Check for hydraulic fluid leaks.6. Verify fluid level in tank (page 10).High Pressure Fluid Hazard:Watch for signs of fluid leaks. Escaping fluid under pressurecan have sufficient pressure to penetrate the skin causingserious injury. Use a piece of paper or cardboard, NOT BODYPARTS, to check for leaks. Wear protective gloves and safetyglasses or goggles when working with hydraulic systems. If anaccident occurs, seek immediate medical attention from aphysician familiar with this type of injury.2013-03-04 Table of Contents Index 401-885M

12 Air-Pro ® PTO Pump Table of Contents Index Great Plains Manufacturing, Inc.Setting Meter PressurizationRefer to Figure 9Meter pressurization is set as for a standard planter,using the PTO kit valve 1 rather than a lever for a tractorhydraulic remote. This adjustment is normally made withthe seed meters full of seed.Consult your planter Seed Rate manual for the correctseed disk, meter inlet shutter setting, and recommendedinitial pressure as reported by the Magnehelic ® gauge 2 .1. Check that the Inlet Butterfly valve handle 3 is setto 30°. If not, loosen the pivot bolt, reset handle, andRe-secure bolt.2. Mount the PTO pump (page 9).3. Per your planter Operator manual, hitch the planter.Raise the planter. Install lift locks. This is to free themeter ground drive wheel.4. Shut off the tractor and remove the key.5. Consult your planter Seed Rate manual for theintended crop, noting:• Range and Transmission sprockets required,• correct Air-Pro ® seed disk (not shown),• initial inlet shutter setting (not shown), and• initial meter pressurization.6. Configure the meter drive system sprockets.7. Install seed disks. Leave rain covers off meters (notshown).8. Set meter inlet shutters per the Seed Rate manual.9. Open any slide gates under hoppers (not shown).10. Load enough seed to completely fill the meter inlettubes, and at least partially fill every hopper.11. Set out containers, under row unit seed tubes, tocollect seed metered during setup.12. Clear the hitch area of non-essential persons. Clearthe hitch area of non-essential persons. Checkessential personnel for long hair, scarfs, cords,frays, loose flaps and anything else that might getentangled. Clear the area of dangling or loosewires, straps, cord and other lines that mightbecome entangled and pull someone in.13. • Check that tractor is in Park or Neutral.• Check parking brake set.• Set the tractor PTO controls for540 rpm gearing (if multi-speed) andclockwise rotation (if bidirectional).• Start tractor engine and set throttle to idle.• Engage the PTO.• Bring the tractor engine and PTO up to intendedfield rpms.142Figure 9:Meter Pressure AdjustmentEntanglement and Crushing Hazard:Use extreme caution in the hitch area when the PTO isoperating.29842251373462614. At the flow control valve, turn the lock disc 4counter-clockwise to release the knob 1 . Slowlyturn the knob counter-clockwise to start the fan.Bring the fan speed up until the Magnehelic ® gaugedisplays the suggested pressure for this crop.15. Turn the meter ground drive wheel forward severalturns, until all exposed cells in all seed disks containseed.16. Recheck the Magnehelic ® gauge. The reportedpressure is likely to have increased. Adjust the flowcontrol knob to bring the pressure reading back tothe recommended value. Tighten the lock disc.17. Shut down the PTO, and as desired, the tractor.18. Install rain covers on seed meters.The PTO pump is now ready for field work. Someadjustment of meter pressure and inlet shutters may berequired, depending on seed and planting conditions.Use the flow control valve, and not the butterfly valve, tomake pressure adjustments.3401-885M Table of Contents Index 2013-03-04

Great Plains Manufacturing, Inc. Table of Contents Index PTO Operation 13PTO UnhitchingThe pump may be dismounted before or after unhitchingthe planter and tractor. With a 3-point planter,dismounting the pump last may be easier, which is theorder shown on this page. For safety, have the tractorcompletely shut down during PTO dismounting.1. At the tractor, shut down the PTO.Note: The PTO may be shut down suddenly or gradually.The fan circuit includes a bypass to recirculateexcess pressure during deceleration. The fan isonly sensitive to sudden acceleration.2. Do not approach the hitch area until the PTO shaft,and the fan, have slowed to a complete stop.3. Mechanically unhitch the planter per the Operatormanual. Leave the PTO pump mounted at this time.4. Pull the tractor forward enough to allow access tothe PTO pump. Put the tractor in Park or Neutral.Engage the parking brake. Shut the tractor down.Remove the key.5. Pass the free end of the pump chain forwardthrough the torque arm keyhole.6. Unwrap the chain from the anchor point anddrawbar.7. Slide the PTO pump off the PTO shaft. Store thepump on the planter. Use the chain to secure it toany available structure.Entanglement Hazard:Remain clear of a rotating PTO shaft. Even when coasting to astop, a PTO shaft can have enough residual torque to inflictserious or fatal injury.Hot Surface Hazard:Remain clear of the pump reservoir during unhitching.The oil may be hot enough to inflict a painful burn.2013-03-04 Table of Contents Index 401-885M

Add oil until the oil level in thetank, as observed on the sight gauge 3 , reaches the fillline on the decal (the horizontal mid-border of the decal).The fill line is 9.15 inches (23.2 cm) above the tankbottom. If the 858-003C decal requires replacement,adjust the center border line to this height.Operate the PTO system briefly, or until the tank levelstops changing. See “PTO Operation” on page 8 foroperations.Recheck the sight gauge. As necessary, add oil to fillline.Oil and Filter ChangeAt a regularly scheduled oil change, also change thefilter. At initial system flush, no filter change is required.Refer to Figure 11 and Figure 101. Wait for the oil to cool before changing the oil.2. Place a container with at least a 7 gallon (26 liter)capacity under the drain plug 1 of the reservoir.3. Carefully remove the drain plug.4. Allow several minutes for oil in the filter to drain intoand out of the reservoir. Change filter as required.See page 16 for filter size. Seat filter perinstructions on filter.5.

Great Plains Manufacturing, Inc. Table of Contents Index 17Appendix A - InstallationBefore You StartMost accidents are the result of negligence andcarelessness, usually caused by failure of the installer tofollow simple but necessary safety precautions. Allow noone to install the Air-Pro ® PTO pump before carefullyreading this manual.Fasteners may be loosely assembled. Remove thembefore mounting the component. Due to evolvingmanufacturing practices, sub-assemblies may already becompletely pre-assembled. If so, check that fasteners aretight, and skip the unneeded assembly steps.Compatible PlantersOne PTO pump kit is always required. Older plantersmay also require a fan update kit.Fan Motor CompatibilityThe Air-Pro ® PTO Pump kits require a 2-port fanhydraulic motor (having no case drain). Older planters,having 3-port fan hydraulic motors (with a case drain)cannot install a PTO kit unless the fan is updated.Check the planter serial number, or inspect the fan.Planters manufactured with 3-port fans are:3Planter ModelYP425AYP425A3PYP625AYP625A3PYP825AYP825A3PSerial Number or LowerB1008NB1004MB1043QB1006PB1014SB1007RIf the planter has a 3-port/case-drain fan motor, orderone fan update kit:KitPart NumberYP4,6,8 FAN UPDATE 401-956AInstructions for installing this kit are merged with theinstructions for the Air-Pro ® PTO Pump kits.B PortA Port2Figure 12:Top: Older 3-Port Fan MotorBottom: Current 2-Port Motor29781317542013-03-04 Table of Contents Index 401-885M

The tongue must be in placefor hose re-routing.• Install the PTO pump system after mounting a fertilizersub-frame (option, pull-type only). This sub-framemust be in place for flow control valve mounting, and insome cases, reservoir mounting.• Install the PTO pump system before installingframe-mounted row options. This improves foot roomand reduces sharp object hazards while working neartool bars.• Install the PTO pump system before installingrow-mounted coulters or row cleaners. This improvesfoot room and reduces sharp object hazards whileworking near tool bars.• Install the PTO pump system before installingmarkers. This eliminates an overhead sharp objecthazard, and improves working space at themainframe.Prepare Planter1. Read and understand “Important SafetyInformation” starting on page 1.2. Position the planter on a level surface in a welllighted location suitable for the installation. A clearsurface beneath makes it easier to recover anydropped parts. If markers are already installed,choose an area with enough room to unfold them.3. Configure the planter for Parking, as instructed inthe planter Operator manual.4. If markers are already installed, unfold them.5. Unhitch the planter.2013-03-04 Table of Contents Index 401-885M
