Before starting the machine each day, perform the Each Use/Daily procedures listed in Daily Maintenance Checklist.

Use only clean, fresh diesel fuel or biodiesel fuels with low (<500 ppm) or ultra low (<15 ppm) sulfur content. The minimum cetane rating should be 40. Purchase fuel in quantities that can be used within 180 days to ensure fuel freshness.

Use summer grade diesel fuel (No. 2-D) at temperatures above -7°C (20°F) and winter grade (No. 1-D or No. 1-D/2-D blend) below that temperature. Use of winter grade fuel at lower temperatures provides lower flash point and cold flow characteristics which eases starting and reduces fuel filter plugging.

Use of summer grade fuel above -7°C (20°F) contributes toward longer fuel pump life and increased power compared to winter grade fuel.

Important: Do not use kerosene or gasoline instead of diesel fuel. Failure to observe this caution damages the engine.

Biodiesel Ready

This machine can also use a biodiesel blended fuel of up to B20 (20% biodiesel, 80% petrodiesel). The petrodiesel portion should be low or ultra low sulfur. Observe the following precautions:

• The biodiesel portion of the fuel must meet specification ASTM D6751 or EN14214.

• The blended fuel composition should meet ASTM D975 or EN590.

• Painted surfaces may be damaged by biodiesel blends.

• Use B5 (biodiesel content of 5%) or lesser blends in cold weather.

• Monitor seals, hoses, gaskets in contact with fuel as they may degrade over time.

• Fuel filter plugging may be expected for a time after converting to biodiesel blended.

• Contact your distributor if you wish for more information on biodiesel.

53 L (14 US gallons)

1. Park the machine on a level surface, lower the cutting units, shut off the engine, and remove the key.

2. Using a clean rag, clean the area around the fuel-tank cap.

3. Remove the cap from the fuel tank (Figure 45).

   

   Figure 45

   1. Fuel-tank cap

4. Fill the tank until the level is to the bottom of the filler neck with diesel fuel.

5. Install fuel-tank cap tightly after filling tank.

   Note: If possible, fill the fuel tank after each use. This minimizes possible buildup of condensation inside the fuel tank.

Important: If your machine fails any of the interlock switch checks, contact your authorized Toro distributor.

Protected under Protected Menus—accessible only by entering PIN

There are operating configuration settings that are adjustable within the Settings Menu of the InfoCenter. To lock these settings, use the Protected Menu.

Note: At the time of delivery, the initial password code is programmed by your distributor.

This machine will dynamically brake and stop when you return the traction pedal to neutral.

Note: For smooth deceleration, use your foot to slowly control the traction pedal back to neutral. Do not take your foot off the pedal and allow it to snap back to the neutral position unless you intend to stop quickly.

The machine should come to a complete stop in approximately 3.7 m (12 ft) from the maximum transport speed of 10 mph.

1. On flat, dry pavement, mark out the start and end of 3.7 m (12 ft).

2. Drive the machine at the maximum transport speed of 16 km/h (10 mph) and remove your foot at the start of the 3.7 m (12 ft).

3. Check if the machine stops within 0.6 m (2 ft) of the end mark (3.7 m or 12 ft).

4. Contact your Toro distributor if the stopping distance of the machine is not within 0.6 m (2 ft) of this distance.

Transport Reverse Speed

• If the maximum transport speed set by the supervisor is above 8.0 km/h (5.0 mph), the maximum reverse speed is 8.0 km/h (5.0 mph).

• If the maximum transport speed set by the supervisor is at or below 8.0 km/h (5.0 mph), maximum reverse speed is equal to the transport speed set by the supervisor.

Mowing Reverse Speed

• If the maximum mow speed set by the supervisor is above 6.4 km/h (4.0 mph), the maximum reverse speed is 6.4 km/h (4.0 mph).

• If the maximum mow speed set by the supervisor is at or below 6.4 km/h (4.0 mph), maximum reverse speed is equal to the transport speed set by the supervisor.

This machine displays estimated traction speeds in kilometers per hour (km/h) or miles per hour (mph).

• The instantaneous speed is displayed in the upper left-hand corner of the cruise control and virtual pedal stop screens.

• The traction speeds are estimated, and calibrated to be most accurate at 8.0 km/h (5.0 mph) while mowing. Displayed speeds are accurate when it is 0.8 km/h (0.5 mph) above or below the display speed while driving on dry, flat pavement.

• Contact your authorized Toro distributor if the machine's observed speeds deviate more than 2.4 km/h (1.5 mph) from the displayed speeds.

Additional horsepower is supplied on-demand from the 48-VDC battery pack and is managed by the PowerMatch^™ system. This additional battery power is intended for short periods of time—not for continuous or sustained periods at maximum horsepower. PowerMatch is made up of 2 different processes:

• When you remove your foot from the traction pedal, the machine dynamically brakes to a stop.

• The pedal controls are optimized to provide a reactive yet stable response, allowing you to maintain consistent control over rough terrain, while still allowing for quick, smooth braking.

• When mowing, the engine speed will automatically raise to high idle.

• The maximum speeds set in the PIN protected menu settings are set by the supervisor to limit the machine’s maximum traction speed.

• The achievable traction pedal use, cruise control, and pedal stop traction speeds are all limited by the maximum speeds set in the PIN protected menu.

• If an obstacle is in the way, lift the cutting units or mow around it.

• When transporting the machine between work areas, shut off the PTO, and raise the cutting units to the fully upward position. This transitions the machine to TRANSPORT mode.

• Always drive slowly in rough areas.

• Never shut off the machine while driving the machine.

This pedal controls the forward and reverse speed of the machine and the dynamic braking when you return it to neutral.

• The further you push the pedal forward or reverse, the faster the machine moves.

• To control the machine to a smooth stop while transporting or mowing, use your foot to return the traction pedal to neutral at your desired rate.

• To engage maximum braking, remove your foot from the traction pedal, allowing it to return to neutral. The machine dynamically brakes to a stop.

This traction system allows you to customize the acceleration settings for operator comfort and course conditions. Refer to Accessing Protected Menus for changing the settings.

Figure 49

1. Traction pedal

The virtual pedal stop (VPS) feature allows you to temporarily set a maximum traction speed that is less than the password-protected supervisor maximum traction speed.

To temporarily set the maximum speed of the machine, press the traction pedal fully forward (Figure 49). You can set a separate speed for the mow range and transport range (Figure 50).

• To access this feature, select the InfoCenter middle button from the main screen (Figure 50).

  Note: This feature reverts back to the supervisor maximum speed settings when the key is switched off.

  

  Figure 50

  1. Indicates the maximum traction speed (pedal stop)
  2. This speed is locked out under the protected PIN menu.

• This feature allows you to customize the speed settings for your comfort level, or to customize the speed settings to fit the application.

Whenever the max traction speed is changed via the supervisor max speed settings or Virtual Pedal Stop, the traction pedal is automatically reprogrammed to use the full pedal stroke between neutral and the new max speed. This means the operator gains more precise control of the traction speed at lower maximum speed settings.

This feature determines how quickly the machine changes traction speed when the traction pedal is not in the NEUTRAL position.

Note: If you take your foot off the traction pedal, allowing it to return to the NEUTRAL position while the machine is moving, the braking profile is engaged. The braking profile is always the same and cannot be customized by the acceleration mode feature.

Enter the protected menus in the InfoCenter to change the acceleration mode. The acceleration mode has the following 3 positions:

• Low—least aggressive acceleration and deceleration

• Medium (default)—medium acceleration and deceleration

• High—most aggressive acceleration and deceleration

When starting the machine in cold weather, warm-up mode limits the engine speed to low idle for a short period after the engine is started, preventing potential component damage from operating the machine with cold oil.

A snowflake icon on the InfoCenter screen denotes when warm-up mode is active. Do not operate the machine until after the warm-up period.

With Smart Power, the operator does not have to listen to the engine speed in heavy load conditions. Smart Power prevents the engine from bogging down in heavy cutting conditions by automatically controlling the machine speed and optimizing cutting performance.

Note: By default, the Smart Power feature is ON.

Important: You must bleed the fuel system before starting the engine if you are starting the engine for the first time, the engine has shut off due to lack of fuel, or you have performed maintenance on the fuel system; refer to Bleeding the Fuel System.

1. Sit on the seat, keep your foot off the traction pedal so that it is in NEUTRAL, engage the parking brake, and ensure that the PTO switch is not engaged.

2. Turn the key to the ON/PREHEAT position.

   An automatic timer controls the glow plug preheat for 6 seconds.

3. After preheating the glow plugs, turn the key to the START position.

   Crank the engine for no longer than 15 seconds. Release the key when the engine starts. If additional preheating is required, turn the key to the OFF position and then to the ON/PREHEAT position. Repeat this process as required.

4. Run the engine at low idle speed until it warms up.

1. Move all controls to NEUTRAL, engage the parking brake, move the engine-speed switch to the LOW IDLE position and allow the engine to reach low idle speed.

   Important: Allow the engine to idle for 5 minutes before shutting it off after a full load operation. Failure to do so may damage engine components.

2. Turn the key in the switch to the OFF position and remove the key.

The turf-compensation spring (Figure 53) transfers the weight from the front roller to the rear roller. This helps to reduce a wave pattern in the turf, also known as marcelling or bobbing.

Important: Make spring adjustments with the cutting unit mounted to the traction unit, pointing straight ahead, and lowered to the shop floor.

1. Make sure that the hairpin is installed in the rear hole in the spring rod (Figure 53).

   Note: When servicing the cutting unit, move the hairpin to the spring-rod hole next to the turf-compensation spring.

   

   Figure 53

   1. Turf-compensation spring
   2. Hairpin
   3. Spring rod
   4. Hex nuts

2. Tighten the hex nuts on the front end of the spring rod until the compressed length of the spring is 15.9 cm (6.25 inches); refer to Figure 53.

   Note: When operating on rough terrain decrease the spring length by 13 mm (1/2 inch). Ground following will be slightly decreased.

   Note: The turf compensation setting will need to be reset if the HOC setting or the Aggressiveness of Cut setting is changed.

You can adjust the amount of counterbalance force applied to the rear cutting-units to help compensate for different turf conditions, and to maintain a uniform height of cut in rough conditions or in areas of thatch buildup.

You can adjust counterbalance force of each torsion spring to 1 of 4 settings. Each increment increases or decreases the counterbalance force on the cutting unit by 2.3 kg (5 lb). You can position the springs at the back side of the first spring actuator to remove all counterbalance (fourth position).

Note: To remove all counterbalance force, position the long leg of the torsion spring above the shouldered stud.

1. Park the machine on a level surface, lower the cutting units, shut off the engine, engage the parking brake, and remove the key.

2. Insert the long end of the counterbalance spring into a tube or similar object, and pivot the spring around the shouldered stud to the desired position (Figure 54).

   

   Figure 54

   2. Shouldered stud

3. Repeat steps 1 and 2 at the other counterbalance spring.

1. Park the machine on a level surface, lower the cutting units, shut off the engine, engage the parking brake, and remove the key.

2. The lift-arm switch is located underneath the hydraulic tank and inboard of the cutting unit #5 lift arm (Figure 21).

   

   Figure 55

3. Loosen the jam nut that secures lift-arm switch to the switch plate (Figure 56).

   

   Figure 56

   1. Switch
   2. Lift-arm sensing device

4. Adjust the lift-arm switch as follows:

   • To increase the lift-arm turnaround height, move the switch down.

   • To decrease the lift-arm turnaround height, move the switch up.

   Important: Maintain an air gap of 1.0 to 2.5 mm (0.040 to 0.100 inches) between the switch and the lift-arm trigger. The LED light on the switch verifies proper function of the switch.

5. Tighten the jam nuts to 20 N∙m +/- 2 N∙m (15 +/- 1.5 ft-lb).

   Important: Do not overtighten the jam nuts; otherwise, you may damage the sensor.

If the Clip Control feature is ON and the machine is operating with settings that correspond to a blank cell in the clip charts, Clip Control is commanding reel speed 9.

If the Clip Control feature is turned off by the supervisor, the front and rear reel speeds can be customized. These clip charts offer recommended reel speeds. Blank cells and configurations not shown in the tables convey that the combination of reel size, number of blades, HOC, and traction speed are not recommended. Mowing at these settings will result in reduced quality of cut.

Important: It is important that proper reel speeds are used for your mowing application.Reel speeds that are too slow may result in a wave pattern in the turf, also known as clip marks, marcelling, or bobbing. If this is observed, try increasing the reel speeds or reducing the mowing speed.Reel speeds that are too fast may result in turf damage and/or premature wear of the reels, bedknives, and other mechanical components.

Refer to Setting the Front and Rear Reel Speeds.

To adjust the reel speed manually, refer to the following:

1. Ensure that the Clip Control feature is Off.

2. In the InfoCenter, under the settings menu, enter the blade count, mow speed, and HOC to calculate the proper reel speed.

3. If further adjustments are required, in the settings menu, scroll down to the F Reel RPM, R Reel RPM, or both.

4. Press the right button to change the reel speed value. As the speed setting is changed, the display continues to show the calculated reel speed based on blade count, mow speed, and HOC, but the new value is also displayed.

   Note: You may need to increase or decrease the reel speed to compensate for varying turf conditions.

This Operator’s Manual contains more detailed fuel and fuel system maintenance information than the engine Owner’s Manual, which is a general-purpose reference relating to fuel and fuel maintenance.

Ensure that you understand that the fuel system maintenance, fuel storage, and fuel quality require your attention to avoid downtime and extensive engine repairs.

The fuel system has extremely tight tolerances due to the emissions and control requirements. Diesel fuel quality and cleanliness is more important for the longevity of today’s high-pressure common rail (HPCR) fuel-injection system used on diesel engines.

Important: Water or air in the fuel system will damage your engine! Do not assume that new fuel is clean. Ensure that your fuel is from a quality supplier, store your fuel correctly, and use your fuel supply within 180 days.

Important: If you do not follow the procedures for fuel filter replacement, fuel system maintenance, and fuel storage, the engine fuel system could fail prematurely. Perform all fuel system maintenance at the specified intervals or whenever the fuel is contaminated or its quality is poor.

Appropriate fuel storage is critical for your engine. Proper maintenance of fuel storage tanks is often overlooked and leads to the contamination of fuel delivered to the machine.

• Acquire only enough fuel that you will consume within 180 days. Do not use fuel that has been stored for more than 180 days. This helps eliminate water and other contaminates in the fuel.

• If you do not remove the water from the storage tank or machine fuel tank, it can lead to rust or contamination in the storage tank and fuel system components. Tank sludge developed by mold, bacteria, or fungus restricts flow and clogs the filter and fuel injectors.

• Inspect your fuel storage tank and machine fuel tank regularly to monitor the fuel quality in the tank.

• Ensure that your fuel comes from a quality supplier.

• If you find water or contaminants in your storage tank or machine fuel tank, work with your fuel provider to correct the problem and perform all fuel system maintenance.

• Do not store diesel fuel in tanks or canisters made with zinc-plated components.
