Operation

Note: Determine the left and right sides of the machine from the normal operating position.

Before Operation

Before Operation Safety

General Safety

  • Never allow children or untrained people to operate or service the machine. Local regulations may restrict the age of the operator. The owner is responsible for training all operators and mechanics.

  • Become familiar with the safe operation of the equipment, operator controls, and safety signs.

  • Always shut off the engine of the traction unit, remove the key, wait for all moving parts to stop, and allow the machine to cool before adjusting, servicing, cleaning, or storing the machine.

  • Know how to stop the machine and shut off the engine quickly.

  • Do not operate the machine without all guards and other safety protective devices in place and functioning properly on the machine.

  • Before operating, always inspect the machine to ensure that the tines are in good working condition. Replace worn or damaged tines.

  • Inspect the area where you will use the machine and remove all objects that the machine could strike.

  • Locate and mark all electrical or communication lines, irrigation components, and other obstructions in the area to be aerated. Remove the hazards, if possible, or plan how to avoid them.

  • Ensure that your traction unit is suitable for use with a machine of this weight. Check with your traction unit supplier or manufacturer.

Outcross Traction Unit Controls

Refer to the Outcross traction unit Operator’s Manual for information on controls and operation, as well as additional information on setting up the machine.

Adjusting the Aeration Depth

Important: Adjust the aeration depth only when the traction unit is parked, the parking brake is engaged, the PTO is disengaged, and the engine is shut off.

  1. Lay the desired tine onto the depth decal while aligning the tine tip with the desired aeration depth as shown in Figure 22.

    decal106-8856
  2. Determine the letter setting aligned with the mounting end of the tine (Figure 22). Adjust the depth control to the corresponding letter on the decal.

  3. Insert a 9/16-inch socket with a ratchet onto the depth adjuster input shaft (Figure 23).

    g007304
  4. Push in on the socket or use your hand to press on the locking plate.

  5. Rotate the depth adjuster clockwise to reduce the aeration depth or counterclockwise to increase the aeration depth. (Figure 23).

  6. Rotate the depth adjuster input shaft until the desired depth is attained as shown on the depth indicator decal (Figure 23).

    Note: 17 revolutions of the depth adjuster input shaft equal approximately 6.4 mm (1/4 inch) depth change.

Understanding the Traction Unit Controls

Familiarize yourself with the operation of the following traction unit controls before operating the machine:

  • PTO engagement

  • 3 point hitch (raise/lower)

  • Clutch

  • Throttle

  • Gear selection

  • Parking brake

    Important: Refer to the traction unit operator's manual for operating instructions.

Understanding the Principles of Operation

The 3-point hitch linkage of the traction unit lifts the machine for transport and lowers it for operation.

Power from the traction unit power take-off (PTO) is transmitted through driveshafts, a gearbox, and drive belts to a number of crankshafts, which drive the tine holding arms into the turf surface.

As the traction unit travels forward with the PTO engaged and the machine lowered, a series of holes are created in the turf.

The penetration depth of the tines is determined by the height of the depth control.

The distance between the aeration holes is determined by the gear ratio (or hydrostatic traction pedal position) of the traction unit and the number of tines in each tine head.

Note: Changing the engine speed does not change hole spacing.

Practicing the Operating Procedures

Important: When connecting the PTO, ensure that the machine is not lifted higher than is necessary. Lifting the machine too high causes the PTO driveshaft knuckles to break (Figure 24). The PTO can operate up to an angle of 25°, but can never exceed a 35° angle when the machine is at its highest position, or severe shaft damage may occur.

g194609

Before using the machine, find a clear area and practice operating the traction unit with the machine installed.

Important: If there are sprinkler heads, electrical or communication lines, or other obstructions in the area being aerated, mark these locations to ensure that these items are not damaged during operation.

  • Operate the traction unit using the recommended gear settings and PTO drive speeds and become thoroughly familiar with the traction unit handling with the attached machine.

  • Practice stopping and starting, raising the machine, and lowering the machine, disengaging the PTO drive, and aligning the machine with previous passes.

Practice sessions helps you gain confidence in the performance of the machine and helps ensure that you are using it properly.

Warning

Adjusting or maintaining the machine while the traction unit is running may result in an accident and severe injury or death

  • Before leaving the operator’s seat, disengage the PTO drive, engage the parking brake, shut off the engine, remove the key, and wait for all moving parts to stop.

  • Lower the machine onto the storage stands or appropriate blocking or jacks repairing the machine.

  • Ensure that all safety devices are secured in proper place before resuming operation.

Preparing to Aerate

Inspect the area of operation for hazards that could damage the machine and remove them, if possible, or plan how to avoid them. Carry replacement tines and tools in case tines are damaged due to contact with foreign materials.

  • Independent wheel brakes should always be locked together when transporting.

  • Operate the machine only in good visibility. Do not operate the machine when there is the risk of lightning.

  • For all PTO driveshaft steel parts (tubes, bearings, joints, etc.) disassembly or repairs, it is highly advisable to contact your local Toro distributor. Removal of components for repairs and reassembly may damage some parts if not performed with special tools by trained technicians.

  • The PTO driveshaft must not be used without the guards supplied.

  • Friction clutches may become hot during use. Do not touch. To avoid the risk of fire, keep the area around the clutch free of flammable material and avoid prolonged slipping of the clutch.

Slope Safety

  • Review the traction unit specifications to ensure that you do not exceed its slope capabilities.

  • Slopes are a major factor related to loss of control and rollover accidents, which can result in severe injury or death. You are responsible for safe slope operation. Operating the machine on any slope requires extra caution.

  • Evaluate the site conditions to determine if the slope is safe for machine operation, including surveying the site. Always use common sense and good judgment when performing this survey.

  • Review the slope instructions listed below for operating the machine on slopes and review the conditions to determine whether you can operate the machine in the conditions on that day and at that site. Changes in the terrain can result in a change in slope operation for the machine.

  • Avoid starting, stopping, or turning the machine on slopes. Avoid making sudden changes in speed or direction. Make turns slowly and gradually.

  • Do not operate a machine under any conditions where traction, steering, or stability is in question.

  • Remove or mark obstructions such as ditches, holes, ruts, bumps, rocks, or other hidden hazards. Tall grass can hide obstructions. Uneven terrain could overturn the machine.

  • Be aware that operating the machine on wet grass, across slopes, or downhill may cause the machine to lose traction. Loss of traction to the drive wheels may result in sliding and a loss of braking and steering.

  • Use extreme caution when operating the machine near drop offs, ditches, embankments, water hazards, or other hazards. The machine could suddenly roll over if a wheel goes over the edge or the edge caves in. Establish a safety area between the machine and any hazard.

Operating the Machine

Note: When using needle tine heads, make sure to read the instructions included with the kit for unique operating procedures.

  1. Lower the machine on the 3 point linkage so that the tines are nearly to the ground at the lowest part of their stroke.

  2. At a low engine rpm, engage the power take off (PTO) clutch to start the machine.

    Important: Never operate the machine without the tine heads installed.

  3. Select a gear that gives a forward speed of approximately 1 to 4 km/h (0.6 to 2.5 mph) at the rated PTO speed of 540 rpm (refer to the traction unit operator's manual).

  4. As the clutch is released and the traction unit moves forward, lower the machine fully into the turf and increase engine speed to give a maximum of 540 rpm at the PTO.

    Important: Never operate the traction unit PTO faster than 540 rpm or you may damage to the machine.

    Note: Make sure that the roller is on the ground.

  5. Note the hole pattern. If you require greater hole spacing, increase forward the speed of the traction unit by shifting up a gear or with a hydrostatic drive traction unit, actuate the hydrostat lever or pedal to give faster speed. For closer hole spacing, decrease traction unit forward speed. Changing engine speed in a particular gear does not change the hole pattern.

    Important: Look backward frequently to ensure that the machine is operating properly and alignment is maintained with previous passes.

  6. Use the front traction unit wheel as a guide to maintain equal lateral hole spacing with the previous pass.

  7. At the end of the aeration pass, raise the machine and disengage the PTO.

  8. If you back into a tight area (like a tee box), disengage the PTO and raise the machine to the highest position. Use caution not to catch the turf guards on the turf.

  9. Always clear the area of all damaged machine parts, such as broken tines, etc., to prevent anything from being picked up and thrown by mowers or other turf maintenance equipment.

  10. Replace broken tines; inspect and repair damaged tines that are serviceable. Repair any other machine damage before operation.

Adjusting the Hole Spacing

The forward hole spacing is determined by the traction unit gear ratio (or the hydrostatic traction pedal). Changing the engine speed does not change the forward hole spacing.

The lateral hole spacing is determined by the number of tines in the tine heads.

Aerating Hard Ground

If the ground is too firm to obtain the desired coring depth, the coring head can get into a “bouncing” rhythm. This is due to the tines attempting to penetrate the hard pan. This condition can be corrected by attempting one or more of the following:

  • Best results are obtained after a rain or when turf has been watered the previous day.

  • Reduce the number of tines per stomper arm. Attempt to maintain a symmetrical tine configuration to evenly load the stomper arms.

  • Reduce tine penetration (depth setting) if the ground is hard packed. Clean up the cores, water the turf, and aerate again at a deeper penetration.

Aeration of soil types built on top of hard subsoils (i.e. sand/soil cap placed over rocky ground) can cause undesired hole quality. This is caused when the aeration depth is greater than the soil cap and the subsoil is too hard to penetrate. When the tines contact this subsoil, the machine may lift and cause the top of the holes to become elongated. Reduce the aeration depth sufficiently to avoid penetration into the hard subsoil.

Using Needle Tines

Long slender tines used in either a needle tine head or mini tine head can leave the front or rear of the hole tufted or slightly deformed. Hole quality for this configuration generally improves if you reduce coring head speed 10 to 15% from full operating speed. Reduce the engine speed until the PTO speed is around 460 to 490 rpm. The forward spacing is not affected by reducing the engine speed. The pushed hole can also be affected by the position of the rotalink damper assembly. Refer to Adjusting the Rotalink Assembly.

Avoiding Root Zone Lifting

Using the mini-tine heads in conjunction with larger coring tines or large diameter solid tines can induce significant stress on the root zone of the turf. This stress can fracture the root zone and cause a lifting action to the turf. If this damage occurs, try one or more of the following:

  • Reduce the tine density (remove some of the tines).

  • Decrease the coring depth.

    Note: Try decreasing core depth in 13 mm (1/2 inch) increments.

  • Increase the forward hole spacing (change the traction unit transmission up one gear).

  • Decrease the tine diameter (solid or coring).

Adjusting the Rotalink Assembly

The mounting height of the rotalink damper assembly affects the reactive force applied to the stomper arm and ground engagement during aeration. In the event of the front of the hole being pushed (elongated or dimpled), a “stiffer” position can help resist this push and improve hole quality. In the event of the back of the hole being pushed (elongated or dimpled) a “softer” position can improve the hole quality.

  1. Remove the 2 locknuts (1/2 inch) securing the rotalink damper assembly to the underside of the coring head frame (Figure 25).

  2. Lower the damper assembly to expose the spacers (Figure 25).

  3. Move 1 or 2 spacers per side from the damper assembly to the top of the coring head frame. Each spacer is equivalent to 1/2 inch. The lower bumper spacer must remain on the damper assembly.

    g007335
  4. Assemble the damper assembly to the coring head frame again. Ensure that the D washer is installed against the coring head frame as shown in Figure 25. Secure the 2 locknuts.

    To see the effects of this adjustment, adjust only 3 to 4 assemblies to compare the original position and the new position on a trial pass. When satisfactory results are achieved, move the remaining assemblies to the same height as the desired arms.

Operating Tips

Warning

Adjusting or repairing the machine while the traction unit is running may result in an accident and severe injury or death

  • Before leaving the operator’s seat, disengaging the PTO drive, engaging the parking brake, shutting off the engine, and remove the key.

  • Before repairing the machine, lower it onto the storage stands or appropriate blocking.

  • Ensure that all safety devices are secured in proper place before resuming operation.

  • Engage the PTO at low engine speed. Increase engine speed to achieve PTO speed of 540 rpm (maximum) and the lower machine. Operate at engine at a speed that the machine runs most smoothly.

    Note: Changing engine/PTO speed in a particular traction unit gear (or fixed hydrostatic pedal position on a traction unit with a hydrostatic transmission) does not change hole spacing.

  • Make very gradual turns when aerating. Never make sharp turns with the machine lowered. Plan your aeration path before lowering the machine.

  • If the operating load slows the engine when aerating the machine on hard ground or going uphill, raise the machine slightly until the engine regains speed, then lower the machine again.

  • Do not aerate if the ground is too hard or dry. Best results are obtained after a rain or when turf has been watered the previous day.

    Note: If the roller rides up off the ground while aerating, the ground is too hard to achieve the desired depth; reduce the aeration depth until the roller contacts the ground during operation.

  • Raise the machine penetration if the ground is hard packed. Clean up cores and aerate at deeper penetration, preferably after watering.

  • The ProCore 864 is offset to the right side of the traction unit to allow aerating without driving over the cores with the tires. Whenever possible, aerate with the longer offset towards the previous aeration pass.

  • Always check/adjust the top link whenever you change the aeration depth. The front of the machine should be vertical.

  • Look backward frequently to ensure that the machine is operating properly, and alignment is maintained with previous passes.

  • Always clear the area of all damaged machine parts, such as broken tines, etc., to prevent them from being picked up and thrown by mowers or other turf maintenance equipment.

  • Replace broken tines, and inspect and correct damage to those still usable. Repair any other machine damage before commencing operation.

After Operation

After Operation Safety

General Safety

  • Park the machine on a level surface; engage the parking brake; shut off the engine; remove the key; and wait for all movement to stop before leaving the machine.

  • Keep all parts of the machine in good working condition and all hardware tightened.

  • Replace all worn, damaged, or missing decals.

Transporting the Machine

To begin transport operation, raise the machine and disengage the PTO. To avoid loss of control, traverse steep inclines slowly, approach rough areas at reduced speed and cross severe undulations carefully.

Important: Do not exceed transport speeds of 24 km/h (15 mph).

Cleaning the Machine after Use

After daily use, thoroughly wash the machine with a garden hose without a nozzle to avoid contamination and seal and bearing damage due to excessive water pressure. You can use a brush to remove caked-on material. Use mild detergent to clean the covers. After cleaning, grease all drive lines and roller bearings, inspect for machine damage, oil leakage, and component and tine wear.

Remove, clean, and oil the tines. Spray a light oil mist on the coring head bearings (crank and damper links).

      • Shut off the engine of the traction unit and remove the key.

      • Wait for all moving parts to stop.

      • Allow machine components to cool before performing maintenance.

    • Perform only those maintenance instructions described in this manual. If major repairs are ever needed or assistance is desired, contact an authorized Toro distributor.

    • Ensure that the machine is in safe operating condition by keeping nuts, bolts, and screws tight.

    • If possible, do not perform maintenance while the engine is running. Keep away from moving parts.

    • Do not check or adjust the chain tension when the traction unit engine is running.

    • Carefully release pressure from components with stored energy.

    • Support the machine with blocks or storage stands when working beneath it. Never rely on the hydraulic system to support the machine.

    • Check the tine mounting bolts daily to be sure that they are tightened to specification.

    • Ensure that all guards are installed and the hood is secured shut after maintaining or adjusting the machine.

    • To ensure safe, optimal performance of the machine, use only genuine Toro replacement parts. Replacement parts made by other manufacturers could be dangerous, and such use could void the product warranty.

    Jacking the Machine

    Caution

    If the machine is not properly supported by blocks or jack stands, the machine may move or fall, which may result in personal injury.

    • Ensure that the machine is parked on a solid, level surface such as a concrete floor. Always chock the traction unit tires.

    • Prior to raising the machine, remove any attachments that may interfere with the safe and proper raising of the machine.

    • When changing attachments or performing other service, use correct blocks, hoists or jacks.

    • Use jack stands or solid wood blocks to support the raised machine.

    Note: If available, use a hoist to lift the rear of the machine. Use the eyelets in the coring head bearing housings as hoist attachment points (Figure 26)

    g007308

    Greasing the Bearings and Bushings

    Maintenance Service IntervalMaintenance Procedure
    Every 50 hours
  • Grease the bearings and bushings.
  • The main working bearings of the machine are sealed for life and require no maintenance or lubrication. This drastically reduces the maintenance required and eliminates the risk of grease or oil being dropped onto the turf.

    There are grease fittings that must be lubricated with an SAE multi-purpose, high-temperature grease with high-pressure (EP) performance or SAE multi-purpose lithium-based grease.

    The lubrication points are:

    PTO driveshaft (3) (Figure 27)

    g007309

    Roller bearings (ProCore 864: 2; ProCore 1298: 4) (Figure 28)

    g007310

    Driveshaft bearings (ProCore 864:1; ProCore 1298: 2) (Figure 29)

    g007311

    Important: Bearings rarely fail from defects in materials or workmanship. The most common reason for failure is moisture and contamination working its way past the protective seals. Bearings that are greased rely upon regular maintenance to purge harmful debris from the bearing area. Sealed bearings rely on an initial fill of special grease and a robust integral seal to keep contaminants and moisture out of the rolling elements.

    The sealed bearings require no lubrication or short term maintenance. Use of sealed bearings minimizes routine service and reduces the potential turf damage from grease contamination. Inspect of bearing condition and seal integrity periodically to avoid downtime. Inspect the sealed bearings seasonally and replaced them if they are damaged or worn. Check that the bearings do not produce high heat, emit noise, vibrate excessively, or weep rust; the bearings should operate smoothly.

    Due to the operating conditions these bearing/seal packages are subject to (i.e. sand, turf chemicals, water, impacts, etc.) they are considered normal wear items. Bearings that fail due to other than defects in materials or workmanship are typically not covered under warranty.

    Note: Bearing life can be negatively affected by improper washing procedures. Do not wash the unit when it is still hot and avoid directing high-pressure or high-volume spray at the bearings.New bearings commonly purge some grease out of the seals on a new machine. This purged grease turns black in color due to collection of debris and not due to excessive heat. Wipe this excess grease from the seals after the initial 8 hours. The area around the seal lip may always appear wet. This is not detrimental to bearing life, but keeps the seal lip lubricated.Replace the coring head bearing every of 500 hours. A bearing service kit that covers the complete coring head is available from your distributor.

    Checking the Gearbox Lubrication

    Maintenance Service IntervalMaintenance Procedure
    Every 100 hours
  • Check the gearbox lubrication.
  • The gearbox is filled with 80W-90 gear oil or equivalent. Allow the gearbox to cool before checking the lubrication.

    1. Clean debris from the fill plug and check the plug to avoid contamination.

    2. Remove the check plug from the gearbox (Figure 30).

      g007312
    3. Make sure that the oil level is up to the bottom of the check plug hole in gearbox (Figure 30).

    4. If the oil level is low, remove the fill plug from the gearbox and add oil as required.

    decal110-4664

    Inspecting the Belts

    Maintenance Service IntervalMaintenance Procedure
    Yearly
  • Inspect the belts.
  • The drive belt(s) on the machine are durable. However, the normal exposure to UV radiation, ozone or incidental exposure to chemicals can deteriorate the rubber compounding over time and lead to premature wear or material loss (i.e. chunking).

    Annual belt inspection is highly recommended for signs of wear, excessive cushion cracks, or large embedded debris with replacement when needed.

    Adjusting the Belt Tension

    Maintenance Service IntervalMaintenance Procedure
    Before each use or daily
  • Check the belt tension.
  • Make sure that the belt is properly tensioned to ensure correct operation of the machine and to prevent unnecessary wear.

    1. Check for proper belt tension by compressing idler spring to a length of 146 mm (5-3/4 inches); refer to Figure 32.

      decal110-4667
    2. Adjust the belt tension as follows:

      1. Remove the rear coring head cover (Figure 33).

    Installing the Belt

    1. Route the new drive belt around the lower end of the #1 stomper arm and up through the coring head frame.

    2. Position the drive belt onto the crank pulley, under the idler assembly and over the drive pulley.

    3. Raise the rotalink damper for the #1 stomper arm to coring head frame. Ensure that the damper spacers are installed in the same position as in removal.

    4. Secure the rotalink damper to the coring head with the 2 washers and locknuts previously removed.

    5. Install and adjust the belt idler pulley and adjust it to the appropriate tension.

    6. Install the dirt shield and the lower belt shield. Adjust the lower shield to ensure clearance with the belt.

    7. Install the pulley and the coring head covers.

    Adjusting the Side Shield

    The coring head side shields should be adjusted so that the bottom rides between 25 to 38 mm (1 to 1-1/2 inches) from the turf while aerating.

    1. Loosen the bolts and nuts securing the side shield to frame (Figure 39).

      g007322
    2. Adjust the shield up or down and tighten the nuts.

    Replacing the Turf Guards

    All turf guards (Figure 40) should be replaced if broken or worn to less than 1/4 inch thickness. Broken turf guards can catch and tear turf, creating undesirable damage.

    Coring Head Timing

    The unitized coring head design of the machine provides industry-leading smooth operation while taking out the guesswork of timing.

    ProCore 864 (Figure 41)

    Each pair of crank arms joined through a bearing housing are timed 180 degrees apart (i.e. arm positions 1-2, 3-4, 5-6, 7-8). The adjacent pairs are all set with the same timing whereas the later pair lags by 120 degrees. The same pair of coupling castings are used between all adjacent pairs (i.e. coupling positions 2-3, 4-5, 6-7). To further reduce operating vibration, 2 counter weights are added at the #1 position on the pulley and the #8 position.

    Note: The numbers cast into the crank arms do not align with the raised indicator mark on the bearing housings for the ProCore 864.

    g007324

    ProCore 1298 (Figure 42)

    This unit is comprised of 2 independent coring heads with 6 arms each. The timing of either coring head is not dependent on the adjacent coring head. The timing marks are easily identified by the numbers cast into the crank arm castings and the raised locator on the bearing housings. The #1 arm always starts with the drive pulley.

    Removing the Machine from the Traction Unit

    Important: Refer to the PTO driveshaft owner’s manual for additional operating and safety information.

    1. Park the traction unit and machine on a level surface, disengage the PTO, engage the parking brake, shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operator's seat.

    2. Install the storage stands and secure them to the machine with the lynch pins (Figure 43).

      g007302

      Note: You can store the machine on the original shipping pallet.

    3. Slowly lower the machine until the storage stands contact the ground.

    4. Loosen the locking nut and rotate the upper adjusting link to release the tension between the machine and the traction unit.

    5. Remove the lynch pin and the top link pin securing the center link to the bracket. Retain the lynch pin and the top link pin with the machine.

    6. Disconnect the safety shield chains from the traction unit PTO (CE only).

    7. Pull back on the lock collar to disconnect the PTO driveshaft from the PTO output shaft on the traction unit.

    8. Slide the PTO driveshaft back and remove it from the traction unit.

    9. Support the PTO driveshaft by connecting the PTO tether to the PTO shield to prevent the driveshaft from contacting the ground (Figure 44).

      g007307
    10. Remove the lynch pins and slide the lower link arms off the hitch pins.

      Retain the lynch pins with the machine.

    Storage

    Storage Safety

    • Before adjusting, cleaning, storing, or repairing the machine, park the it on a level surface; engage the parking brake of the traction unit; shut off the engine; remove the key; and wait for all movement to stop before leaving the traction unit.

    • Store the machine on the storage stands positioned on a firm, level surface so that it does not sink or tip over.

    • Store the machine away from areas of human activity.

    • Do not allow children to play on or around the stored machine.

    Storing the Machine

    At the end of an aerating season or when the machine is stored for a long period, do out the following procedure:

    1. Clean off any dirt or grease that may have accumulated on the machine or any of the moving parts.

    2. Remove and clean out the tines. Coat the tines with oil to prevent rusting during storage.

    3. Open the hood and clean out the inside of the machine.

    4. Lubricate all grease fittings.

    5. Store the machine on the provided storage stands on a hard, dry surface.

    6. Support the PTO driveshaft in the stored position with the tether to prevent damage, or remove the PTO and store it under the hood to minimize corrosion.

    7. Paint the roller and touch up any other scratches on the painted surfaces.

    8. Replace any missing or damaged decals.

    9. Store the machine inside a dry, secure building. Inside storage reduces maintenance, gives a longer working life, and increases the residual value of the machine. If inside storage is not available, cover the machine with a heavy sheet or tarpaulin and secure it tightly.
