Slope Safety

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. Before you operate the machine, review the site 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.
- 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.
- Identify hazards at the base of the slope. If there are hazards, mow the slope with a pedestrian-controlled machine.
- If possible, keep the cutting units lowered to the ground while operating on slopes. Raising the cutting units while operating on slopes can cause the machine to become unstable.

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.

During Operation

Overview of the Machine Operating Characteristics

This machine has an automotive-style throttle that is controlled by the traction pedal.
This machine does not have a separate throttle switch or throttle lever.
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.
While transporting, the traction pedal will operate similar to a car and change the engine and traction speed dependent on the traction pedal position.
When mowing, the engine speed will automatically raise to high idle.
If the engine is at low idle, performing a function like lifting the cutting units or pressing the traction pedal raises the engine speed to a minimum working speed, providing enough power to efficiently perform the function.
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.

Machine Operation

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 allows the traction pedal to operate like a car.
Always drive slowly in rough areas.
Never shut off the machine while driving the machine.

Practice Operating the Machine

To get familiar with the features of the machine, practice operating the machine.

Lift the cutting units, disengage the parking brake, press the forward traction pedal, and carefully drive to an open area.
Practice driving the machine, because it has a hydrostatic transmission and its features can differ from other turf-maintenance machines.
Practice moving forward and reverse, and starting and stopping the machine. To stop the machine, remove your foot from the traction pedal and let it return to Neutral.

Note: When going downhill in the machine, you may need to engage the parking-brake switch or use the reverse pedal to stop.
Practice driving around obstacles with the cutting units up and down. Be careful when driving between narrow objects so that you do not damage the machine or cutting units.

Overview of the Traction Pedal

G439020

The traction pedal

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

This machine has an automotive-style throttle — the engine speed and the machine speed respond to the pedal movement.
While transporting, the traction pedal will operate similar to a car and change the engine and traction speed dependent on the traction pedal position.
While mowing, the engine automatically raises to high idle to optimize mowing performance, and the traction pedal only controls traction speed.
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.

Overview of the Virtual Pedal Stop (VPS) Feature

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. You can set a separate speed for the mow range and transport range.

To access this feature, press the up or down navigation button from the main screen.

Note: This feature reverts back to the supervisor maximum speed settings when the key is switched off.
G462150s
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 maximum traction speed is changed via the supervisor maximum speed settings or Virtual Pedal Stop, the traction pedal is automatically reprogrammed to use the full pedal stroke between neutral and the new maximum speed. This means the operator gains more precise control of the traction speed at lower maximum speed settings.

Tips for Using Virtual Pedal Stop (VPS)

Set the max speed temporarily lower for mowing the cleanup pass on the fairway.
Set the max speed temporarily lower for improved control operating in or near the maintenance shop.
Set the max speed temporarily lower for improved control loading the machine onto a trailer.

Cruise Control

Cruise Control Operation

G439038.svg

The cruise-control switch

locks in the cruise control to maintain the desired ground speed. Pressing the rear of the switch turns the cruise control off, the middle position of the switch enables the cruise-control function, and the front of the switch sets the desired ground speed.

After the cruise control switch is enabled and the speed is set, use the InfoCenter display to adjust the speed setting of the cruise control.

To disengage the cruise control use the following:

When in transport range, press the reverse traction pedal, engage the parking brake, or press the cruise control switch to the Off position.
When in mow range, press the reverse traction pedal, engage the parking brake, disengage the PTO, or press the cruise control switch to the Off position.

Note: Disengaging cruise control results in the machine dynamically braking to a stop. If you would like to disengage cruise control but continue driving, press the traction pedal and then disengage the cruise control for a smooth transition from cruise control to manual speed control.

Adjusting the Cruise Control Speed

Enable the cruise control switch on the console.
Use the InfoCenter display to adjust the speed setting of the cruise control.
G462143s
1. Indicates the cruise control speed
2. Indicates the maximum traction speed (pedal stop)
3. This speed is locked out under the protected PIN menu.

Tips for Using the Cruise Control

Set a cruising speed for long distances without many obstacles.
On rough terrain, use the InfoCenter display to control the speed.
Use the cruise control for turnarounds as follows:
1. While mowing, set a safe, comfortable speed for turning around at the end of mowing passes.
2. Press the traction pedal to increase the speed for mowing during the mowing pass.
3. Take your foot off the pedal when turning around for the next mowing pass.
4. The machine will slow down to the low cruise control setting, allowing you to make an efficient turnaround at a constant speed.
5. After turning around, use the traction pedal to increase the machine speed back up for the next mowing pass.

Overview of the Acceleration Mode

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 on the InfoCenter display 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

Overview of the Warm-Up Mode

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 display screen denotes when warm-up mode is active. Do not operate the machine until after the warm-up period.

Overview of Toro Smart Power™

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.

Starting the Engine

Important

The fuel system automatically bleeds itself 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.

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.
Turn the key to the On/Preheat position.

An automatic timer controls the glow plug preheat for 6 seconds.
After preheating the glow plugs, turn the key to the Start position.

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

Shutting Off the Engine

Move all controls to Neutral, engage the parking brake, and allow the engine to reach low idle speed.
Turn the key to the Off position and remove it from the switch.

Adjusting the Turf-Compensation Spring

The turf-compensation spring

transfers weight from the front 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 ground.

Make sure that the hairpin cotter is installed in the rear hole in the spring rod .

G402845

Tighten the hex nuts on the front end of the spring rod until the compressed length of the spring is 12.7 cm (5 inches) for 5-inch cutting units or 15.9 cm (6.25 inches) for 7-inch cutting units.

Note: When operating on rough terrain, decrease the spring length by 12.7 mm (1/2 inch). This slightly decreases the ground following.

Cutting Grass with the Machine

Disengage the parking brake, disengage the PTO, and raise the cutting units.
Drive the machine to the mowing area.
Park the machine approximately 6 m (20 ft) off the fairway, facing the intended mowing direction.
Lower the cutting units completely with the lift/lower control lever.
Engage the PTO.

Note: The cutting units will not start.

Note: The engine speed automatically rises to high idle when you lower the cutting units and activate the PTO switch.
Tap the lift/lower control lever rearward to lift the cutting units to the turnaround position.

Note: Tapping the lift/lower control lever without holding it raises the cutting units to the turnaround position and stops the rotation of the reels until the cutting units are lowered.
Using the traction pedal, approach the mowing area slowly.
Once you reach the edge of the mowing area to start mowing, lower the cutting units with the lift/lower control lever.

Note: Practice to ensure the cutting units do not lower early or mow an unintended area.
Complete the mowing pass.
When nearing the opposite edge of the fairway (prior to reaching the edge of the mowing area), tap the lift/lower control lever rearward to lift the cutting units to the turnaround position.
Perform a tear-shaped turn to quickly line up for your next pass.
Press the lift/lower control lever to automatically lower the cutting units from the turnaround position and continue mowing.
After mowing the desired area, follow the perimeter of the area to complete the cleanup mow pass. This will ensure that all of the turf along the edge of the fairway where the cutting units were being lifted and lowered is uniformly cut.

Note: Use the Virtual Pedal Stop (VPS) to temporarily set a lower maximum speed to improve operating control while completing the cleanup pass.

Understanding the Diesel-Particulate Filter and Regeneration

The diesel-particulate filter (DPF) removes soot from the engine exhaust.

The DPF regeneration process uses heat from the engine exhaust that is increased by the catalyst to convert accumulated soot into ash.

To keep the DPF clean, remember the following:

Run the engine at full engine speed when possible to promote DPF self-cleaning.
Use the correct engine oil.
Minimize the amount of time that you idle the engine.
Use only ultra low sulfur diesel fuel.

Operate and maintain your machine with the function of the DPF in mind. Engine under load generally produces adequate exhaust temperature for DPF regeneration.

Important

Minimize the amount of time that you idle the engine or operate the engine at low-engine speed to help reduce the accumulation of soot in the DPF.

Caution

The exhaust temperature is hot (approximately 600°C (1,112°F) during DPF regeneration. Hot exhaust gas can harm you or other people.

Do not operate the engine in an enclosed area.
Ensure that there are no flammable materials around the exhaust system.
Ensure that the hot exhaust gas does not contact surfaces that may be damaged by heat.
Do not touch a hot exhaust system component.
Do not stand near or around the exhaust pipe of the machine.

Understanding the Regeneration Icons

	A parked or recovery regeneration is requested. Perform the regeneration immediately.

	A regeneration is acknowledged and the request is processing.
	A regeneration is in progress and the exhaust temperature is elevated.
	NOx control system malfunction; the machine requires service.

Types of Diesel Particulate Filter Regeneration

Types of diesel particulate filter regeneration that are performed while the machine is operating:

Type of Regeneration	Conditions that cause DPF regeneration	DPF description of operation
Passive	Occurs during normal operation of the machine at high-engine speed or high-engine load	The InfoCenter does not display an icon indicating passive regeneration. During passive regeneration, the DPF processes high-heat exhaust gasses, oxidizing harmful emissions, and burning soot to ash.
Assist	Occurs because of low-engine speed, low-engine load, or after the computer detects the DPF is becoming obstructed with soot	The InfoCenter does not display an icon indicating assist regeneration. During assist regeneration, the engine computer adjusts the engine settings to raise the exhaust temperature.
Reset	Occurs every 100 hours Also occurs if normal engine operation surpasses the allowed soot accumulation amount within the filter	When the high exhaust-temperature icon is displayed in the InfoCenter, a regeneration is in progress. During reset regeneration, the engine computer maintains an elevated engine speed to ensure filter regeneration.
Reset

Types of diesel particulate filter regeneration that require you to park the machine:

Type of Regeneration	Conditions that cause DPF regeneration	DPF description of operation
Parked	Occurs because the computer determines that the automatic DPF cleaning has not been sufficient. Also occurs because you initiate a parked regeneration May occur because the inhibit regen has been initiated and has disabled the automatic DPF cleaning from occuring May result from using the incorrect fuel or engine oil	When the reset-standby/parked or recovery regeneration icon or a regeneration is requested. Perform the parked regeneration as soon as possible to avoid needing a recovery regeneration. A parked regeneration requires 30 to 60 minutes to complete. You must have at least a 1/4 tank of fuel in the tank. You must park the machine to perform a parked regeneration.
Parked
Recovery	Occurs because the request for parked recovery has been ignored, allowing the DPF to be critically plugged	When the reset-standby/parked or recovery regeneration icon a recovery regeneration is requested. A recovery regeneration requires up to 3 hours to complete. You must have at least a 1/2 tank of fuel in the machine. You must park the machine to perform a recovery regeneration.

Adjusting the Lift-Arm Counterbalance

Rear Cutting Units

Caution

The springs are under tension, and adjusting them could result in minor or moderate personal injury.

Use caution when adjusting the springs.

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.

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.

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

G402848

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.
Repeat step 2 for the other counterbalance spring.

Adjusting the Lift-Arm Turnaround Position

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

G439043

Locate the lift-arm switch underneath the hydraulic tank and inboard of the cutting unit #5 lift arm.

G439054

Loosen the jam nut that secures lift-arm switch to the switch plate .
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.
Torque the jam nuts to 20 +/- 2 N∙m (15 +/- 1.5 ft-lb).

Important

Do not overtorque the jam nuts; otherwise, you may damage the sensor.

Setting the Reel Speed

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.

To adjust the reel speed manually, complete the following:

In Machine Settings, enter the blade count, mow speed, and HOC to calculate the proper reel speed.
If further adjustments are required, in Machine Settings , scroll down to Front Reel Speed, Rear Reel Speed, or both.
Press the right navigation 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 shown.

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

Operating Tips

Overview of the Warning System

If a warning light comes on during operation, stop the machine immediately and correct the problem before continuing operation. Serious damage could occur if you operate the machine with a malfunction.

Transporting the Machine

Disengage the PTO and raise the cutting units to the Transport position. Be careful when driving between objects so you do not accidentally damage the machine or cutting units. Use extra care when operating the machine on slopes. Drive slowly and avoid sharp turns on slopes to prevent rollovers. Lower the cutting units when going downhill for steering control.

Overview of Mowing Patterns

This is the most effective method to prevent washboarding.

Change mowing patterns often to minimize a poor after-cut appearance from repeatedly mowing in the same direction.

Proper Mowing Techniques

To achieve the professional straight-line cut and striping that is desirable for some applications, find a tree or other object in the distance and drive straight toward it.
Maintain reel and bedknife sharpness.
Maintain proper reel to bedknife clearance. Use light contact.
Follow and maintain the 1/3rd rule (cut only 1/3 of the grass blade at a time).
Set reel speed and traction speed to obtain the desired clip length.
When mowing in wet conditions, open the rear shield of the cutting unit.

Scalping, Circle Cutting, and Verticutting

Scalping/Circle Cutting
- Scalping and circle cutting are considered severe applications. Dedicate reels specifically to these applications.
- Follow and maintain the 1/3rd rule (cut only 1/3 of the grass blade at a time).
Verticutting
- For 5-inch verticutters, set the verticutter blade depth to 1/8 inch or less. For 7-inch verticutters, set the blade depth to 1/4 inch or less.
- Ensure that the cutting-unit blades are sharp, adjusted correctly, and that none of the blades are bent. Dull and bent blades require more power.
- Adding more blades to reduce the blade spacing increases power consumption.
Best Practices for Scalping, Circle Cutting, and Verticutting
- Open the rear cutting-unit shields.
- Recommended maximum mowing speed is 6 km/h (4 mph).
- Set the reel speeds to setting 6.
  
  Note: Higher reel speed settings result in less torque. When scalping, better performance and efficiency is achieved at lower reel speed settings.
- Do not use Economy Mode.
- Use the InfoCenter display to monitor the engine coolant temperature.
- Frequently check the rear radiator screen and the air cleaner air inlet screen above the radiator for chaff build up.
- If the engine overheats, park the machine in a shaded area with good air flow to let the components cool.

Maintaining the Machine after Mowing

Complete the following steps after mowing:

Thoroughly wash the machine with a garden hose with no nozzle to avoid contamination and damage to the seals and bearings caused by excessive water pressure.
Ensure that the radiator and oil cooler are kept free of dirt or grass clippings.
Inspect the machine for possible hydraulic-fluid leaks, damage, or wear to the hydraulic and mechanical components, and check the cutting-unit blades for sharpness.

G439096
1. Rear tie-down

Hauling the Machine

Follow the tips below when hauling the machine.
- Use full-width ramps for loading the machine onto a trailer or truck.
- Tie the machine down securely.

Pushing or Towing the Machine

In an emergency, you can move the machine forward by actuating the bypass valve in the variable-displacement hydraulic pump and pushing or towing the machine.

Important

Do not push or tow the machine faster than 3 to 4.8 km/h (2 to 3 mph). If you push or tow at a faster speed, internal transmission damage may occur.

The bypass valves must be open and the brake released whenever you push or tow the machine.

Unlatch the seat base and tilt the seat open.
Locate the bypass valves under the seat and on the top of the hydrostat.

G439099
Loosen the valves with 3 turns to allow the oil to bypass internally.

Note: Because the fluid is bypassed, the machine can be moved slowly without damaging the transmission.
Locate the brake release manifold near the front right tire and behind the hydraulic tank.

G439110

Insert a tube or similar object, hold the black knob in on the manifold, and pump the manifold 3 times. As soon as there is substantial resistance when pumping, the brake is released.

Important

Do not pump the manifold after it does not pump easily. Damage could occur if the manifold is pumped too much.

Note: Once the pressure is built up in the manifold, the brake will be released for approximately 60 minutes. If needed after 60 minutes, release the brake again by pumping the manifold.
Push or tow the machine.
Set the brake by pulling the black knob out or starting the engine.

Note: The brake automatically resets when you start the engine.
Close the bypass valves. Torque the valves to 11 N∙m (5 to 8 ft-lb).

Important

Ensure that the bypass valves are closed before you start operating the machine. Running the engine with an open bypass valve causes the transmission to overheat.

Maintenance

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

Note: Download a free copy of the electrical or hydraulic schematic by visiting www.Toro.com and searching for your machine from the Manuals link on the home page.

Important

Refer to your engine owner’s manual and cutting unit Operator's Manual for additional maintenance procedures.

Fuel System Maintenance

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.

Fuel Storage

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.
