   1. Electrolyte

4. Allow approximately 20 to 30 minutes for the electrolyte to soak into the plates. Fill as necessary to bring the electrolyte to within about 6 mm (1/4 inch) of the bottom of the fill well (Figure 4).

5. Connect a 2 to 4 A battery charger to the battery posts. Charge the battery for at least 2 hours at 4 A or for at least 4 hours at 2 A until the specific gravity is 1.250 or higher and the temperature is at least 16°C (60°F) with all cells gassing freely.

   Warning

   Charging the battery produces gasses that can explode.

   Never smoke near the battery and keep sparks and flames away from the battery.

   Important: If you do not charge the battery for at least the time specified above, you may reduce the life of the battery.

6. When the battery is charged, disconnect the charger from the electrical outlet and battery posts.

   Note: After the battery has been activated, add only distilled water to replace normal loss, although maintenance-free batteries should not require water under normal operating conditions.

   Important: Failure to correctly activate the battery may result in battery gassing and/or premature battery failure.

7. Install the vent caps.

Parts needed for this procedure:

1. Mount the battery with the battery terminals toward the front of the machine.

2. Connect the positive battery cable (red) from the starter solenoid to the positive post (+) of the battery (Figure 5). Secure it with a carriage bolt and nut.

   Important: Ensure that the cable will clear the seat in the rear-most position, which could cause wear or damage to the cable.

   Warning

   Battery terminals or metal tools could short against metal machine components causing sparks. Sparks can cause the battery gasses to explode, resulting in personal injury.

   • When removing or installing the battery, do not allow the battery terminals to touch any metal parts of the machine.

3. Secure the left side of the roll bar to the mounting bracket with 4 bolts (1/2 x 1-1/2 inches) and locknuts (Figure 6).

4. Torque the fasteners to 91 to 115 N∙m (67 to 85 ft-lb).

5. Secure the right side of the roll bar and the previously removed jack pad to the mounting bracket with 2 bolts (1/2 x 1-1/2 inches), 2 bolts (1/2 x 1-3/4 inches), and locknuts as illustrated in Figure 6.

6. Torque the fasteners to 91 to 115 N∙m (67 to 85 ft-lb).

Parts needed for this procedure:

Important: Do not raise the suspension to the transport position when the reel motors are in the holders on the machine frame. Damage to the motors or hoses could result.

Note: When sharpening, setting the height of cut, or performing other maintenance procedures on the cutting units, store the cutting unit reel motors in the support tubes on the front of the frame and side of the machine to prevent damaging the hoses.

1. Remove the cutting units from the cartons. Assemble and adjust them as listed in the cutting unit Operator's Manual.

2. Slide the cutting unit under the pull frame while sliding the lift hook onto the lift arm (Figure 7).

   

   Figure 7

   1. Lift arm
   2. Lift hook

3. Slide the sleeve back on the ball joint receiver and hook the receiver onto the cutting unit ball stud. Release the sleeve so that it slides over the stud and locks the assemblies together (Figure 8).

   

   Figure 8

   1. Pull frame
   2. Pull arm
   3. Ball stud

4. Mount the baskets on the pull frames, loosen the jam nuts on the pull arms, and adjust the ball sockets until there is 6 to 13 mm (1/4 to 1/2 inch) clearance between the lip of the basket and the reel blades.

   Note: This prevents the basket from tipping the cutting unit forward, causing the lift roller to come off the lift arm while in the mowing operation.

   Note: Ensure that the basket lip is equidistant from the reel blades all across each reel. If the basket is too close to the reel, it is possible for the reel to contact the basket when the cutting unit is raised off or lowered to the ground.

5. Align the sockets in the ball joints so the open side of the socket is centered toward the ball stud, and tighten the jam nuts to secure the sockets in position (Figure 9).

   

   Figure 9

• Fuel tank capacity: 26.6 L (7 US gallons)

• Recommended Fuel:

  • For best results, use only clean, fresh (less than 30 days old), unleaded gasoline with an octane rating of 87 or higher ((R+M)/2 rating method).

  • Ethanol: Gasoline with up to 10% ethanol (gasohol) or 15% MTBE (methyl tertiary butyl ether) by volume is acceptable. Ethanol and MTBE are not the same. Gasoline with 15% ethanol (E15) by volume is not approved for use. Never use gasoline that contains more than 10% ethanol by volume, such as E15 (contains 15% ethanol), E20 (contains 20% ethanol), or E85 (contains up to 85% ethanol). Using unapproved gasoline may cause performance problems and/or engine damage, which may not be covered under the warranty.

  • Do not use gasoline containing methanol.

  • Do not store fuel either in the fuel tank or fuel containers over the winter unless you use a fuel stabilizer.

  • Do not add oil to gasoline.

Important: Do not use fuel additives other than a fuel stabilizer/conditioner. Do not use fuel stabilizers with an alcohol base such as ethanol, methanol, or isopropanol.

1. Clean around the fuel-tank cap and remove it (Figure 22).

   

   Figure 22

   1. Fuel-tank cap

2. Add unleaded regular gasoline to the fuel tank until the level is 25 mm (1 inch) below the bottom of the filler neck.

   This space in the tank allows the fuel to expand. Do not fill the fuel tank completely full.

3. Install the cap.

   Note: You will hear a click sound when the cap is secure.

4. Wipe up any fuel that may have spilled.

Before starting the machine each day, perform the following procedures:

• Check the engine-oil level—refer to Checking the Engine Oil.

• Check the hydraulic-fluid level—refer to Checking the Hydraulic-Fluid Level.

• Check the reel-to-bedknife contact—refer to Checking the Reel-to-Bedknife Contact.

• Check the tire pressure—refer to Checking the Tire Pressure.

Refer to the engine manual supplied with the machine for oil change and maintenance procedures recommended during the break-in period.

Only 8 hours of mowing operation is required for the break-in period.

Since the first hours of operation are critical to future dependability of the machine, monitor its functions and performance closely so that minor difficulties, which could lead to major problems, are noted and can be corrected. Inspect the machine frequently during break-in for signs of oil leakage, loose fasteners, or any other malfunction.

Note: Inspect the area beneath the mowers to be certain they are clear of debris.

1. Sit on the seat, ensure that the parking brake is engaged, disengage the raise/lower mow control, and move the functional control lever to the NEUTRAL position.

2. Ensure that your foot is not on the traction pedal and make sure the pedal is in the NEUTRAL position.

3. Move the choke lever to the ON position (only when starting a cold engine) and the throttle lever to the HALF THROTTLE position.

4. Start the engine and regulate the choke to keep it running smoothly.

5. As soon as possible, open the choke by pulling it rearward to the OFF position.

   Note: A warm engine requires little or no choking.

6. Check the machine out with the following procedures after the engine has started:

   1. Move the throttle lever to the FAST position.

   2. Move the traction-control lever to the MOW position and momentarily engage the reels by moving the raise/lower mow-control lever forward.

      The cutting units should drop and all the reels should rotate.

   3. Move the raise/lower mow control lever rearward until the cutting units raise to the full transport position.

      The cutting units stop rotating as soon as they start to lift. If you release the lever before the cutting units are fully raised, the upward motion stops, but the cutting units still stop rotating.

   4. Lock the parking brake and shut off the engine.

   5. Check the lip of each basket to ensure it is not in contact with the reel during operation.

      If you see signs of contact, adjust the pull arms; refer to Installing the Cutting Units.

   6. Check for oil leaks and tighten the hydraulic fittings if any are found.

      Note: When the machine is new and the bearings and reels are tight, it is necessary to use the FAST throttle lever position for this check. A fast throttle setting may not be required after the break-in period.

      Note: If oil leaks continue to appear, contact your authorized Toro distributor for assistance and, if necessary, replacement parts.

      Important: A trace of oil on the motor or wheel seals is normal. Seals require a small amount of lubrication to perform properly.

1. Move the throttle lever to the SLOW position, disengage the raise/lower mow control, and move the functional-control lever to the NEUTRAL position.

2. Rotate the ignition key to the OFF position to shut off the engine. Remove the key from the switch to prevent accidental starting.

3. Close the fuel shut-off valve before storing the machine.

The purpose of the safety-interlock system is to prevent operation of the machine where there is possible injury to the operator or damage to the machine.

The safety-interlock system prevents the engine from starting unless:

• The traction pedal is in the NEUTRAL position.

• The functional-control lever is in the NEUTRAL position.

The safety-interlock system prevents the machine from moving unless:

• The parking brake is disengaged.

• The operator is seated.

• The functional-control lever is in the MOW position or the TRANSPORT position.

The safety-interlock system prevents the reels from operating unless the functional-control lever is in the MOW position.

Perform the following system checks daily to ensure that the interlock system is operating correctly:

1. Sit on the seat, move the traction pedal to the NEUTRAL position, move the functional-control lever to the NEUTRAL position, and engage the parking brake.

2. Try to press the traction pedal.

   The pedal should not press, which means that the interlock system is operating correctly. Correct the problem if it is not operating properly.

3. Sit on the seat, move the traction pedal to the NEUTRAL position, move the functional-control lever to the NEUTRAL position, and engage the parking brake.

4. Move the functional-control lever to the MOW position or the TRANSPORT position and try to start the engine.

   The engine should not turnover or start, which means that the interlock system is operating correctly. Correct the problem if it is not operating properly.

5. Sit on the seat, move the traction pedal to the NEUTRAL position, move the functional-control lever to the NEUTRAL position, and engage the parking brake.

6. Start the engine and move the functional-control lever to the MOW position or the TRANSPORT position.

   The engine should shut off, which means that the interlock system is operating correctly.

   Correct the problem if it is not operating properly.

7. Sit on the seat, move the traction pedal to the NEUTRAL position, move the functional control lever to the NEUTRAL position, and engage the parking brake.

8. Start the engine.

9. Release the parking brake, move the functional control lever to the MOW position, and rise from the seat.

   The engine should shut off, which means that the interlock system is operating correctly. Correct the problem if it is not operating properly.

10. Sit on the seat, move the traction pedal to the NEUTRAL position, move the functional control lever to the NEUTRAL position, and engage the parking brake.

11. Start the engine.

12. Move the raise/lower mow control forward to lower the cutting units. The cutting units should lower but not start rotating.

    If they start rotating, the interlock system is not operating correctly; correct the problem before operating the machine.

Ensure that the cutting units are fully raised. Move the functional-control lever to the TRANSPORT position. Use the brakes to slow the machine while going down steep hills to avoid loss of control. Always approach rough areas at a reduced speed and cross severe undulations carefully. Familiarize yourself with the width of the machine. Do not attempt to pass between objects that are close together to prevent costly damage and downtime.

Before mowing greens, find a clear area and practice starting and stopping the machine, raising and lowering the cutting units, turning, etc.

Inspect the green for debris, remove the flag from the cup, and determine the best direction to mow. Base the direction to mow on the previous mowing direction. Always mow in an alternate pattern from the previous mowing so that the grass blades are less apt to lay down and therefore be difficult to trap between the reel blades and the bedknife.

1. Approach the green with the functional-control lever in the MOW position and the throttle at full speed.

2. Start on 1 edge of the green so that you can use the ribbon procedure of cutting.

   Note: This holds compaction to a minimum and leaves a neat, attractive pattern on the greens.

3. Actuate the raise/lower mow lever as the front edges of the grass baskets cross the outer edge of the green.

   Note: This procedure drops the cutting units to the turf and starts the reels.

   Important: The No. 1 cutting unit reel is delayed; therefore, you should practice to gain the required timing necessary to minimize the cleanup mowing operation.

4. Overlap a minimal amount with the previous cut on return passes.

   Note: To assist in maintaining a straight line across the green and keep the machine an equal distance from the edge of the previous cut, establish an imaginary sight line approximately 1.8 to 3 m (6 to 10 ft) ahead of the machine to the edge of the uncut portion of the green (Figure 23). Some find it useful to include the outer edge of the steering wheel as part of the sight line; i.e., keep the steering wheel edge aligned with a point that is always kept the same distance away from the front of the machine.

5. As the front edges of the baskets cross the edge of the green, move the raise/lower mow lever rearward and hold it until all the cutting units have risen. This stops the reels and lifts the cutting units.

   Note: It is important to time this step correctly so that you do not cut into the fringe area yet cut as much of the green as possible to minimize the amount of grass left to mow around the outer periphery.

6. To cut down on operating time and ease lineup for the next pass, momentarily turn the machine in the opposite direction, then turn it in the direction of the uncut portion; i.e., if intending to turn right, first swing slightly left, then right.

   Note: This helps to get the machine more quickly aligned for the next pass. Try to make as short of a turn as possible except during warmer weather when a wider arc minimizes the turf bruising.

   

   Figure 23

   1. Alignment strip
   2. Approximately 12.7 cm (5 inches)
   3. Cut grass on the left
   4. Keep a focal spot 2 to 3 m (6 to 10 ft) ahead of the machine.

   Note: The steering wheel does not return to its original position after you complete a turn.

   Important: Never stop the machine on a green with the cutting unit reels operating as damage to the turf may result. Stopping the machine on a wet green may leave marks or indentations from the wheels.

7. If the leak detector alarm (if equipped on your model) sounds or you notice an oil leak while cutting on a green, immediately raise the cutting units, drive directly off the green, and stop the machine in an area away from the green. Determine the cause of the leak and correct the problem.

8. Finish cutting the green by mowing the outer periphery. Be sure to change the direction of cutting from the previous mowing.

   Note: Always keep weather and turf conditions in mind and be sure to change the direction of mowing from the previous cutting.

9. When finished mowing the outer periphery, tap the raise/lower mow lever rearward to stop the reels, then drive off the green. When all the cutting units are off of the green, raise them.

   Note: This minimizes grass clumps left on the green.

10. Replace the flag.

11. Empty the grass baskets of all clippings before transporting to the next green.

    Note: Heavy wet clippings place an undue strain on the baskets and add unnecessary weight to the machine, thereby increasing the load on the engine, hydraulic system, brakes, etc.

After mowing, thoroughly wash the machine with a garden hose without a nozzle so that excessive water pressure does not contaminate and damage the seals and bearings. Do not wash a warm engine or electrical connections with water.

After cleaning, inspect the machine for possible hydraulic fluid leaks, damage or wear to hydraulic and mechanical components, and the cutting units for sharpness. Also, lubricate the brake-shaft assembly with SAE 30 oil or spray lubricant to deter corrosion and help keep the machine performing satisfactorily during the next mowing operation.

• Use care when loading or unloading the machine into a trailer or a truck.

• Use full-width ramps for loading the machine into a trailer or a truck.

• Tie the machine down securely using straps, chains, cable, or ropes. Both front and rear straps should be directed down and outward from the machine.

In case of an emergency, you can tow the machine for up to 0.4 km (1/4 mile).

Important: Do not tow the machine faster than 3 to 5 km/h (2 to 3 mph) to avoid damaging the drive system. If you must move the machine more than 0.4 km (1/4 mile), transport it on a truck or trailer.

1. Locate the bypass valve on the pump and rotate it so that the slot is vertical (Figure 24).
