Use only electrolyte (1.265 Specific Gravity) to fill battery initially.

1. Remove the wing nuts, washers, and battery clamp and lift out the battery.

   Important: Do not add electrolyte while the battery is in the machine. You could spill it, causing corrosion.

2. Clean the top of the battery and remove the vent caps (Figure 3).

   

   Figure 3

3. Carefully fill each cell with electrolyte until the plates are covered with about 6 mm (1/4 inch) of fluid (Figure 4).

   

   Figure 4

   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 amp battery charger to the battery posts. Charge the battery for 2 hours at 4 amps or for 4 hours at 2 amps 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 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.

   Warning

   Battery terminals or metal tools could short against metal tractor 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 tractor.

   • Do not allow metal tools to short between the battery terminals and metal parts of the tractor.

   Warning

   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 wrench and coat the terminal with petroleum jelly. Make sure 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 tractor 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 tractor.

A selection of Toro approved attachments and accessories is available for use with the machine to enhance and expand its capabilities. Contact your Authorized Service Dealer or Distributor or go to www.Toro.com for a list of all approved attachments and accessories.

Please carefully read all of the safety instructions and symbols in the safety section. Knowing this information could help you or bystanders avoid injury.

The use of protective equipment, such as but not limited to, for eyes, ears, feet, and head is recommended.

The engine is shipped with 1.4 liters (1.5 quarts) (w/filter) of oil in the crankcase; however, the oil level must be checked before and after the engine is first started.

The engine uses any high-quality detergent oil having the American Petroleum Institute (API) service classification of SG, SH, or SJ or higher. The recommended viscosity (weight) is SAE 30.

1. Position the machine on a level surface.

2. Pull the dipstick out and wipe it with a clean rag. Push the dipstick into the tube and make sure it is seated fully (Figure 20).

   

   Figure 20

   1. Dipstick
   2. Filler cap

3. Pull the dipstick out of the tube and check the oil level.

4. If the oil level is low, remove the filler cap from the valve cover and pour oil into the opening in the valve cover until the oil level is up to the Full mark on the dipstick. Add the oil slowly and check the level often during this process. Do not overfill.

   Important: Check the oil level every 8 operating hours or daily.

5. Install the filler cap and dipstick firmly in place.

• Fuel tank capacity: 26.6 liters (7 U.S. 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 warranty.

  • Do not use gasoline containing methanol.

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

  • 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 21).

   

   Figure 21

   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 gasoline to expand. Do not fill the fuel tank completely full.

3. Install the fuel tank cap securely. Wipe up any gasoline that may have spilled.

The hydraulic fluid reservoir is filled at the factory with approximately 32.2 l (8.5 U.S. gallons) of high quality hydraulic fluid. Check the level of the hydraulic fluid before the engine is first started and daily thereafter. The recommended replacement fluid is as follows:

Alternate fluids: If the Toro fluid is not available, other fluids may be used provided they meet all the following material properties and industry specifications. We do not recommend the use of synthetic fluid. Consult with your lubricant distributor to identify a satisfactory product

Note: Toro will not assume responsibility for damage caused by improper substitutions, so use only products from reputable manufacturers who will stand behind their recommendation.

Important: The ISO VG 46 Multigrade fluid has been found to offer optimal performance in a wide range of temperature conditions. For operation in consistently high ambient temperatures, 18° C (65° F) to 49° C (120° F), ISO VG 68 hydraulic fluid may offer improved performance.

Premium Biodegradable Hydraulic Fluid-Mobil EAL EnviroSyn 46H

Important: Mobil EAL EnviroSyn 46H is the only synthetic biodegradable fluid approved by Toro. This fluid is compatible with the elastomers used in Toro hydraulic systems and is suitable for a wide-range of temperature conditions. This fluid is compatible with conventional mineral oils, but for maximum biodegradability and performance the hydraulic system should be thoroughly flushed of conventional fluid. The oil is available in 19 l (5 gallon) containers or 55 gallon drums from your Mobil Distributor.

Note: Many hydraulic fluids are almost colorless, making it difficult to spot leaks. A red dye additive for the hydraulic system oil is available in 20 ml (2/3 oz) bottles. One bottle is sufficient for 15-22 1 (4-6 gallons) of hydraulic oil. Order part no. 44-2500 from your authorized Toro distributor. This red dye is not recommended for use with biodegradable fluids. Use food coloring.

Important: Regardless of the hydraulic fluid type used, any traction unit used for off green applications, verticutting or used during ambient temperatures above 29° C (85° F) should have Oil Cooler Kit, Part No. 105-8339, installed.

1. Position the machine on a level surface. Make sure the machine has cooled down so the oil is cold. Check the oil level by viewing the sight window on the side of the auxiliary oil tank (Figure 22). If the oil level is between the two marks on the sight window, the oil level is sufficient.

2. If the oil level is below the bottom mark in the sight window, remove the cap from the hydraulic oil tank and slowly fill the tank with the appropriate high quality hydraulic fluid until the level is between the two marks on the sight window. Do not mix oils. Install the cap.

   Important: To prevent system contamination, clean the top of the hydraulic oil containers before puncturing them. Ensure that the pour spout and funnel are clean.

   Note: Make a close visual inspection of the hydraulic components. Inspect them for leaks, loose fasteners, missing parts, improperly routed lines, etc. Make any corrections necessary.

The tires are over-inflated at the factory for shipping purposes. Reduce the pressure to the proper levels before starting the unit.

Vary the tire pressure for the front wheels, depending upon your turf conditions, from a minimum of 55 kPa to a maximum of 83 kPa (8 to 12 psi).

Vary the tire pressure for the rear wheel from a minimum of 55 kPa to a maximum of 103 kPa (8 to 15 psi).

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.

To ensure optimum performance of the brake system, burnish (break-in) the brakes before using the machine. To burnish the brakes, firmly apply the brakes and drive the machine at mowing speed until the brakes are hot, as indicated by their smell. An adjustment to the brakes may be required after break-in; refer to Adjusting the Brakes.

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

1. Sit on the seat, lock the parking brake, disengage the raise/lower mow control and move the functional control lever to Neutral.

2. Remove your foot from the traction pedal and make sure the pedal is in the Neutral position.

3. Move the choke lever to the closed position (only when starting a cold engine) and the throttle lever to the half throttle position.

4. Insert and rotate the ignition key clockwise until the engine starts. After the engine starts, regulate the choke to keep the engine running smoothly. As soon as possible, open the choke by pulling it rearward to the Off position. A warm engine requires little or no choking.

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

   1. Move the throttle control to the Fast 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 turn.

   2. Move the raise/lower mow control lever rearward. The cutting reels should stop and the cutting units should raise to the full transport position.

      Important: Stop the engine. Check the lip of each basket to be sure it is not in contact with the reel during operation. Adjust the pull arms if contact is noted; refer to Installing the Cutting Units (For cutting unit models 04610, 04611, 04616, 04618, 04619, and 04624 only).

   3. Depress the brake pedal to keep the machine from moving, and operate the traction pedal through the forward and reverse positions.

   4. Continue the above procedure for 1-2 minutes. Neutralize the functional control lever, lock the parking brake, and turn the engine off.

   5. Check for oil leaks. If oil leaks appear, check the tightness of the hydraulic fittings. If oil leaks continue to appear, contact your local 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.

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

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

The safety interlock system prevents the engine from starting unless:

• The traction pedal is in neutral.

• The functional control lever is in neutral.

The safety interlock system prevents the machine from moving unless:

• The parking brake is off.

• The operator is seated.

• The functional control lever is in Mow or Transport.

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 be sure the interlock system is operating correctly:

1. Sit on the seat, move the traction pedal to Neutral, move the functional control lever to Neutral, and engage the parking brake. Try to depress the traction pedal. The pedal should not depress, which means that the interlock system is operating correctly. Correct the problem if it is not operating properly.

2. Sit on the seat, move the traction pedal to Neutral, move the functional control lever to Neutral, and engage the parking brake. Move the functional control lever to mow or transport and try to start the engine. The engine should not crank, 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 Neutral, move the functional control lever to Neutral, and engage the parking brake. Start the engine and move the functional control lever to mow or transport. The engine should kill, which means that the interlock system is operating correctly. Correct the problem if it is not operating properly.

4. Sit on the seat, move the traction pedal to Neutral, move the functional control lever to Neutral, and engage the parking brake. Start the engine. Release the parking brake, move the functional control lever to mow, and rise from the seat. The engine should kill, 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 Neutral, move the functional control lever to Neutral, and engage the parking brake. Start the engine. Move the raise/lower mow control forward to lower the cutting units. The cutting units should not start rotating. If they do, the interlock system is not operating correctly. Correct the problem.

The leak detector system is designed to assist in early detection of hydraulic oil system leaks. If the oil level in the main hydraulic reservoir, is lowered by 118-177 ml (4 to 6 ounces), the float switch in the tank will close. After a one second delay, the alarm will sound, alerting the operator (Figure 25). Expansion of oil, due to normal heating during machine operation, will cause the oil to transfer into the auxiliary oil reservoir. The oil is allowed to return to the main tank when the ignition switch is turned off.

To achieve a consistent, high quality-of-cut and a uniform after cut appearance, it is important that the reel speed control (located on the manifold block under seat) be correctly set.

Adjust the reel speed control as follows:

1. Select the height-of-cut at which the cutting units are set.

2. Choose the desired ground speed best suited for conditions.

3. Using the appropriate graph (See Figure 27) for 8, 11 or 14 blade cutting units, determine the proper reel speed setting.

   Note: Reel speed can be increased or decreased to compensate for turf conditions.

To assist in aligning the machine for successive cutting passes, it is suggested the following be done to the No. 2 and No. 3 cutting unit baskets:

1. Measure in approximately 12.7 cm (5 inches) from the outer edge of each basket.

2. Either place a strip of white tape or paint a line onto each basket paralleling the outer edge of each basket (Figure 29).

   

   Figure 29

   1. Alignment strip
   2. Approximately 12.7 cm (5 inches)
   3. Cut grass on right
   4. Keep focal spot 1.8-3 m (6-10 ft) ahead of the machine.

Before mowing greens with the machine, it is recommended that you find a clear area and practice starting and stopping, raising and lowering the cutting units, turning, etc. This training period will be beneficial to the operator in gaining confidence in the performance of the machine.

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 will be less apt to lay down and therefore be difficult to trap between the reel blades and bedknife.

1. Approach the green with the functional control lever in the Mow position and the throttle at full speed. Start on one edge of the green so the ribbon procedure of cutting may be used. This holds compaction to a minimum and leaves a neat, attractive pattern on the greens.

2. Actuate the raise/lower mow lever as the front edge of the grass baskets cross the outer edge of the green. This procedure drops the cutting units to the turf and starts the reels.

   Important: Familiarize yourself with the fact that the No. 1 cutting unit reel is delayed and therefore, you should practice to try to gain the required timing necessary to minimize the cleanup mowing operation.

3. Overlap a minimal amount with the previous cut on return passes. 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 29 and Figure 30). 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 (Figure 29 and Figure 30).

4. As the front of the baskets cross the edge of the green, move the raise/lower mow lever rearward. This will stop the reels and lift the cutting units. Timing of this procedure is important, so the mowers do not cut into the fringe area. However, as much of the green as possible should be cut to minimize the amount of grass left to mow around the outer periphery.

5. Cut down on operating time and ease lineup for the next pass by momentarily turning the machine in the opposite direction, then turning in the direction of the uncut portion; i.e., if intending to turn right, first swing slightly left, then right. This will assist in getting the machine more quickly aligned for the next pass. Follow the same procedure for turning in the opposite direction. It is a good practice to try to make as short of a turn as possible. However, turn in a wider arc during warmer weather to minimize the possibility of bruising the turf.

   

   Figure 30

   2. Approximately 12.7 cm (5 inches)
   3. Cut grass on left
   4. Keep focal spot 1.8-3 m (6-10 ft) ahead of the machine.

   Note: Due to the nature of the power steering system, the steering wheel will not return to its original position after a turn has been completed.

   Important: The machine should never be stopped on a green with the cutting unit reels operating as damage to the turf may result. Stopping on a wet green with the machine may leave marks or indentations from the wheels.

6. If the leak detector alarm sounds while cutting on a green, immediately raise the cutting units, drive directly off of the green and stop the machine in an area away from the green. Determine the cause of the alarm and correct the problem.

7. Finish cutting the green by mowing the outer periphery. Be sure to change the direction of cutting from the previous mowing. Always keep weather and turf conditions in mind and be sure to change the direction of mowing from the previous cutting. Replace the flag.

8. Empty the grass baskets of all clippings before transporting to the next green. Heavy wet clippings place an undue strain on the baskets and will add unnecessary weight to the machine, thereby increasing the load on the engine, hydraulic system, brakes, etc.

The leak detector alarm may sound for one of the following reasons:

• A leak of 118-177 ml (4 to 6 ounces) has occurred.

• The oil level in the main reservoir is reduced by 118–177 ml (4 to 6 ounces) due to contraction of the oil by cooling.

If the alarm sounds, it should be turned off as quickly as possible and inspected for leaks. If the alarm sounds while operating on a green it may be appropriate to drive off the green first. The source of the leak should be determined and repaired before continuing operation. If a leak is not found, and a false leak is suspected, move the ignition switch to the Off position and allow the machine to stand for 1-2 minutes to allow the oil levels to stabilize. Then start the machine and operate in a non-sensitive area to confirm no leak exists.

False alarms, due to oil contraction, may be caused by extended idling of the machine after normal operation. A false alarm may also occur, if the machine is worked at a reduced workload after an extended period of a heavier workload. To avoid false alarms, turn the machine off rather than idling for extended periods.

Make sure the cutting units are in the full up position. Set the shift selector in No. 2 if conditions will permit faster ground speed. Shift to No. 1 and operate at slower ground speeds in rough or hilly areas. 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 (shift selector in No. 1), and cross severe undulations carefully. Familiarize yourself with the width of the machine. Do not attempt to pass between objects that are close together so that costly damage and down time can be prevented.

At the completion of the mowing operation, thoroughly wash the machine with a garden hose without a nozzle so excessive water pressure will not cause contamination and damage to the seals and bearings. 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 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.

In case of an emergency the machine can be towed for a short distance (less than 0.4 km (1/4 mile)). However, Toro does not recommend this as standard procedure.

Important: Do not tow the machine faster than 3-5 km/h (2-3 mph) because the drive system may be damaged. If the machine must be moved a considerable distance, 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 31 ).
