Fuel Safety

Danger

Gasoline is extremely flammable and vapors are explosive.

A fire or explosion from gasoline can burn you, others, and cause property damage.

  • Fill the fuel tank outdoors on level ground, in an open area, when the engine is cold. If fuel is spilled, Do not attempt to start the engine. Move away from the area of the spill and avoid creating any source of ignition until fuel vapors have dissipated.

  • Do not refill the fuel tank or drain the machine indoors or inside an enclosed trailer.

  • Never smoke when handling gasoline, and stay away from an open flame or where gasoline fumes may be ignited by spark.

  • Add fuel before starting the engine. Never remove the cap of the fuel tank or add fuel when engine is running or when the engine is hot.

  • Store gasoline in an approved container and keep it out of the reach of children.

  • Do not operate without entire exhaust system in place and in proper working condition.

  • In certain conditions during fueling, static electricity can be released and cause a spark, which can ignite gasoline vapors.

    • Do not fill containers inside a vehicle or on a truck or trailer bed with a plastic liner. Always place containers on the ground and away from your vehicle before filling.

    • When practical, remove gas-powered equipment from the truck or trailer and refuel the equipment with its wheels on the ground. If this is not possible, then refuel such equipment on a truck or trailer from a portable container, rather than from a gasoline dispenser nozzle.

    • If a gasoline dispenser nozzle is used, keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete. Do not use a nozzle lock-open device.

  • Do not overfill the fuel tank. Fill the fuel tank to the bottom of the filler neck. The empty space in the tank allows gasoline to expand. Overfilling may result in fuel leakage or damage to the engine or emission system.

  • Gasoline is harmful or fatal if swallowed. Long-term exposure to vapors may cause serious injury and illness.

    • Avoid prolonged breathing of vapors.

    • Keep your face away from the nozzle and the gas tank/container opening.

    • Keep away from eyes and skin.

  • To help prevent fires:

    • Keep the engine and engine area free from accumulation of grass, leaves, excessive grease or oil, and other debris that can accumulate in these areas.

    • Clean up oil and fuel spills and remove fuel-soaked debris.

    • Allow the machine to cool before storing the machine in any enclosure. Do not refuel or store the machine and fuel container where there is an open flame, spark, or pilot light such as on a water heater or other appliance.

During Operation Safety

The operator and/or supervisor must use their full attention when operating the machine. Do not engage in any activity that causes distractions; otherwise, injury or property damage may occur.

Warning

Operating engine parts, especially the muffler, become extremely hot and can cause severe burns on contact. Debris, such as leaves, grass, and brush, can catch fire.

Clean the machine as stated in the Maintenance section. Keep the engine and engine area free from accumulation of grass, leaves, excessive grease or oil, and other debris that can accumulate in these areas.

    • Before clearing blockages.

    • Whenever you leave the mower. Do not leave a running machine unattended.

  • Shut off the engine and wait for all moving parts to stop before refueling and before making height-of-cut adjustments.

  • Tragic accidents can occur if the operator and/or supervisor is not alert to the presence of children. Children are often attracted to the machine and the mowing activity. Never assume that children will remain where you last saw them.

    • Keep children out of the mowing/operating area and under the watchful care of another responsible adult, not the operator or supervisor.

    • Be alert and shut off the machine if children enter the area.

    • Before and while backing up or changing direction, look behind, down, and side-to-side for small children.

    • Never allow children to operate the machine.

    • Do not carry children, even with the blades shut off. Children could fall off and be seriously injured or interfere with the safe operation of the machine. Children that have been given rides in the past could suddenly appear in the operating area for another ride and be run over or backed over by the machine.

  • If the machine rolls over, stay away from moving parts.

Slope Safety

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

    • Review and understand the slope instructions in the guide and on the machine.

    • Evaluate the site conditions of the day to determine if the slope is safe for machine operation. Use common sense and good judgment when performing this evaluation. Changes in the terrain, such as moisture, can quickly affect the operation of the machine on a slope.

  • Operate across slopes; never up and down. Avoid operation on excessively steep or wet slopes. Poor footing could cause a slip-and-fall accident.

  • Identify hazards at the base of the slope. Do not operate the machine near drop-offs, ditches, embankments, water, or other hazards. The machine could suddenly roll over if a wheel goes over the edge or the edge collapses. Keep a safe distance between the machine and any hazard. Use a handheld tool to operate in these areas.

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

  • Do not operate a machine under any conditions where traction, steering, or stability is in question. 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. The machine can slide even if the drive wheels are stopped.

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

  • If you lose control of the machine, step away from the direction of travel of the machine.

  • Always keep the machine in gear when going down slopes. Do not coast downhill.

After Operation Safety

  • Park the machine on level ground, disengage drives, engage the parking brake, shut off the engine, and remove the key. Wait for all moving parts to stop before leaving the operator’s position. Allow the machine to cool before servicing, adjusting, fueling, cleaning, or storing.

  • Clean grass, leaves, excessive grease or oil, and other debris from the mower deck, muffler, drives, and engine area to help prevent fires.

  • Check the radar sensors and make sure they are clean of dirt, grass, leaves, and other debris after every operation.

  • Close the fuel-shutoff valve and turn the battery-disconnect switch to the OFF before storing or transporting the machine.

  • The sensors for the object detection system are functioning properly.

  • Removal of new temporary obstacles such as tools, lawn furniture, sporting goods, and toys left in the operating area since the operating area was previously mowed.

  • No new permanent objects need to be excluded (i.e., newly planted trees, new landscaping, new physical structures).

  • The supervisor is responsible for ensuring that all exclusion areas have been recorded prior to autonomous operation. For recording instructions, refer to the Starting a Recording Session.

    Important: The supervisor will need to create a new recording session if an exclusion area needs to be added after a recording session has been finished.

Adding Fuel

Fuel Tank Capacity

18.9 L (5 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 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.

Using Stabilizer/Conditioner

Use a fuel stabilizer/conditioner in the machine to provide the following benefits:

  • Keeps fuel fresh longer when used as directed by the fuel-stabilizer manufacturer

  • Cleans the engine while it runs

  • Eliminates gum-like varnish buildup in the fuel system, which causes hard starting

    Important: Do not use fuel additives containing methanol or ethanol.

    Add the correct amount of fuel stabilizer/conditioner to the fuel.

    Note: A fuel stabilizer/conditioner is most effective when mixed with fresh fuel. To minimize the chance of varnish deposits in the fuel system, use fuel stabilizer at all times.

Adjusting the Height of Cut

Warning

When the two front support rod hairpins are removed from the mower deck, the weight of the tractor section may cause the front frame of the machine to rise suddenly. If the machine rises suddenly, injury may occur.

Securely hold down the front of the machine when raising the mower deck for hairpin repositioning.

The height of cut of the mower deck is adjusted from 2.54 cm to 11.4 cm (1 to 4-1/2 inches) in 7 mm (1/4-inch) increments.

  1. Park the machine on a level surface, disengage the PTO, and move the motion control levers outward to the PARK position.

  2. Shut off the machine, remove the key, and wait for all moving parts to stop before leaving the operating position.

  3. Lift the cutting deck using the handle as shown in Figure 16 (handle position varies with deck size) to the highest position possible. Engage deck height change assist lever by shifting forward until contact with the deck support rod is felt (see Figure 17). While the lever is manually engaged, lower the deck to rest on the lever.

    2. Deck raised

  4. On lifted deck side, install hairpin clips in the holes for the desired cutting height (see Figure 18).

    Important: To maintain correct cutting height and rake, check the following for proper adjustment.

    1. The front and rear hairpins are in the same holes with the proper spacers under the hair pins (see Figure 18).

    2. The tire pressures are set as directed in Checking the Tire Pressure.

    3. The length of the rear deck support link assemblies average 197 mm (7.76 inches or approximately 7-3/4 inches) from the center of the balljoint to the center of the farthest hole (see Figure 19).

      Note: All four pins must equally support the weight of the deck. Adjustment in the length of the rear deck support assemblies may be necessary. Check lifted side rear support to meet average length as stated in step 3. When lifted opposing rear support is checked, adjust to same length as previous rear support. After lowering deck (de-latching) check that all four support pin rings are loaded. Adjust either rear pin assembly side as needed.

      g518376

      2. 3/4 inch (19 mm)
      3. 3/8 inch (9.5 mm)

  5. Repeat steps 3 and 4 for opposite side.

  6. Lift deck to de-latch and lower until the pin makes contact with the thrust washer.

    Note: Deck height change assist levers are not intended to be used during transport or as cut height positions. During operation, vibration and jerky movements will lift the cutting deck enough to allow spring return disengagement of levers. This will result in sudden drop of the cutting deck, causing possible damage. Levers are also not intended to be used as tie-down locations during transport.

Adjusting the Anti-Scalp Rollers

It is recommended to change the anti-scalp roller position when the height of cut has changed.

  1. Park the machine on a level surface, disengage the PTO, and move the motion-control levers outward to the PARK position.

  2. Shut off the machine, remove the key, and wait for all moving parts to stop before leaving the operating position.

  3. Remove the nut and bolt position the anti-scalp rollers and install the nut and bolt.

  4. Ensure that the spacers and bushings are installed (Figure 20).

    g583685

    Figure 20

    For cutting heights above 90 mm (3-1/2 inches) use the bottom hole. The rollers will still be effective against scalping.

Operating Area – Autonomous Operation

If there is not a previously recorded operating area one will have to be recorded before autonomous operations can be started.

Important: The locations must meet Autonomous Operating Area Criteria .

Starting a Recording Session

In order to create an operating area an operator must complete a recording session. Recording can only be accomplished when the machine is in Manual Mode. The first step in the recording session is to record the boundary. The operator must choose whether or not the blades are engaged while recording.

  1. With the mode select in the Manual Mode position, determine a start point for the planned boundary and drive the machine to that start point. The machine should be facing the direction the operator plans to begin driving once the boundary recording has been started.

  2. To start a boundary recording press down on the front of the Record Mode switch (record boundary position). The status indicator lights will turn solid blue to indicate the boundary recording is in process, and will turn off once the boundary is confirmed or canceled.

  3. Follow the instructions on the message display to confirm or cancel the boundary. To be prompted to confirm the boundary, the operator must drive the entire boundary path, returning to the point at which they started the boundary recording.

  4. Once a boundary has been successfully recorded, the operator can either continue the recording session by adding exclusion areas or finish the recording session.

  5. If adding exclusion areas to the recording session, first determine a start point on the perimeter of the exclusion area and drive the machine to that start point. The machine should be facing the direction the operator plans to begin driving once the exclusion area recording has been started.

    Important: Ensure all permanent objects in the operating area are recorded as exclusion areas to minimize risk of contact with the machine.

  6. To start the exclusion area recording press down on the back of the Record Mode switch (record exclusion area position). The status indicator lights will turn solid blue to indicate the exclusion area recording is in process, and will turn off once the exclusion area is confirmed or canceled.

  7. Follow the instructions on the message display to confirm or cancel the exclusion area. To be prompted to confirm the exclusion area, the operator must drive the entire exclusion area perimeter, returning to the point at which they started the exclusion area recording

  8. Continue adding exclusion areas to the recording session or finish the recording session by following the instructions on the message display.

  9. The operating area is automatically stored upon finishing the recording session. Once an operating area is uploaded it is available anytime the mower is within the boundary of the operating area.

Starting Autonomous Operation

Important: A machine supervisor must be within the line of sight at all times while the machine is operating in Auto Mode. The supervisor must be capable of remotely interrupting/stopping autonomous operation of the machine.

Before the machine can start the autonomous operation, the following conditions must be met:

  • An operating area must be created.

  • The machine must be parked within the operating area.

  • The sulky must be in transport position or removed from the machine.

  • The blades must be disengaged.

  • The motion-control levers must be placed in the outward T-slots (PARK position).

  • The engine must be running and the throttle set to high idle.

  • No objects detected by sensors.

  • Machine is indicating it has cellular, GNSS, and RTK signals.

  • The supervisor must position the mode select switch to Auto Mode.

    Note: An initial fill path is generated the first time a machine is parked within an operating area and the mode select switch is set to Auto Mode. The fill angle used for the fill path is determined by the direction the machine is facing when Auto Mode is selected.

When all machine conditions are met, the operator is ready to start autonomous operation.

Note: An user acknowledgement must be confirmed in the mobile app each time a path is loaded to the machine.

To confirm the user acknowledgement:

  1. Open the mobile app to the Dashboard screen.

  2. Select the machine waiting for user acknowledgement confirmation (it will be highlighted in orange).

  3. Read the user acknowledgement statement that appears and select “Acknowledge and Confirm” if you are prepared for the machine to begin autonomous operation, otherwise select “Close”.

    g573735j

    Figure 21

    1. Close
    2. Acknowledge and Confirm

To start the autonomous operation:

  1. Press the “Auto Start” switch. Green indicator lights and amber blinking warning lights will turn on, indicating the machine is capable of autonomous operation. The green indicator lights and amber blinking lights will remain on while the machine is capable of autonomous operation.

  2. There will be a minimum two second delay before autonomous operation can begin. The audible alarm will sound during this delay. This delay is to allow time for the operator to move away from the machine. Exit the machine towards the rear.

  3. Following the delay, the machine will move to the starting location for the operating area.

    Important: If the machine contacts an object or becomes immobilized, use the remote stop to ensure the machine has stopped autonomous operation before approaching or interacting with the machine.

  4. Once the machine has moved to the starting location, it will pause for two seconds while the audible alarm sounds. After this two second delay, the blades will turn on and the machine will begin mowing the operating area.

The supervisor can review progress of the autonomous operation by accessing the “XiQ” mobile app.

Upon completion of the entire fill path, the machine will stop and the blades will disengage. The amber blinking lights will turn off and green indicator lights will turn off. A message will appear on the screen to let the operator know the job has been completed.

Interruption of Autonomous Operation

Autonomous operation is interrupted by any of the following:

  • If the machine detects an object

    • Close to the machine: the machine stops, the engine stops, PTO is disengaged, the amber blinking lights turn off, the indicator lights turn from green to red, and an audible alarm sounds until the blades stop rotating. Operator intervention is required to reset the machine.

    • Further from the machine: the machine stops (but engine remains running), PTO is disengaged, the amber lights flash fast, an audible alarm sounds until the blades stop rotating. The machine can return to an autonomous operation if the obstacle clears this zone within 30 seconds. If the obstacle is present after 30 seconds, the engine remains running, the amber blinking lights turn off, and the green indicator lights turn red signaling operator intervention is required.

  • If the machine encounters a fault:

    The machine stops, the PTO is disengaged, an audible alarm sounds until the blades stop rotating, the amber blinking lights turn off, and the green indicator lights turn red. Operator intervention is required to reset the machine.

  • If the mobile device is used to remotely stop the machine:

    The machine stops, the PTO is disengaged, an audible alarm sounds until the blades stop rotating, the amber blinking lights turn off, and the green indicator lights turn red. Operator intervention is required to reset the machine.

To use the mobile app to remotely stop the machine:

  1. Open the mobile app to the Dashboard screen.

  2. Select the desired machine to open the machine details screen.

  3. Select the Graphic in the lower right hand corner of the screen.

    g573756j

    Figure 22

Advisories, Faults, and Fault Handling

The machine will detect advisories and faults and communicate them to the operator. When an advisory or fault is detected, the operation of the machine is halted, and a message will appear on the message display screen.

  • Advisories will alert the operator that something on the machine is limited in capability or function. When an advisory is active a message will display on the message display screen that has amber text and the amber LEDs on the message display screen will flash.

  • Faults alert the operator that something is wrong with part of the machine that needs to be addressed. When a fault is active, a message will display on the message display screen that has red text and the red LEDs on the message display screen will flash.

Some advisories and faults will require the operator to interact with the machine. When this happens, the status indicator lights will turn red and the fault clear button will need to be pressed to reset the fault or advisory. If autonomous operations was interrupted, the process outlined in Starting Autonomous Operation will have to be repeated in order to resume operating autonomously.

After Operation

Important: Review the safety messages and safe operating practices Safety after operating the machine.

    Fuel System Maintenance

    Danger

    In certain conditions, fuel is extremely flammable and highly explosive. A fire or explosion from fuel can burn you and others and can damage property.

    Refer to Fuel Safety for a complete list of fuel related precautions.

    Changing the Fuel Filter

    Service Interval: As required

    A fuel filter is installed between the fuel tank and the engine. Replace when necessary.

    Note: Reinstall the fuel line hoses and secure them with plastic ties as originally routed to keep the lines away from components that could cause damage.

    Electrical System Maintenance

    Checking the Battery Charge–

    Service Interval: As required

    Allowing batteries to stand for an extended period of time without recharging them will result in reduced performance and service life. To preserve optimum battery performance and life, recharge batteries in storage when the open circuit voltage drops to 12.1 V.

    Note: To prevent damage due to freezing, batteries should be fully charged before putting away for winter storage.

    Charge batteries in an open, well-ventilated area away from spark and flames. Unplug the charger before connecting or disconnecting from the battery. Wear protective clothing and use insulated tools.

    Danger

    Charging or jump-starting the battery may produce explosive gases. Battery gases can explode, causing serious injury.

    • Keep sparks, flames, or cigarettes away from the battery.

    • Ventilate when charging or using the battery in an enclosed space.

    • Make sure that the battery venting path is always open once the battery is filled with acid.

    • Always shield your eyes and face from battery.

    Danger

    Battery electrolyte contains sulfuric acid, which is poisonous and can cause severe burns. Swallowing electrolyte can be fatal or can cause severe burns if it touches skin.

    • Wear safety glasses to shield eyes, and wear rubber gloves to protect your skin and clothing when handling electrolyte.

    • Do not swallow electrolyte.

    • In the event of an accident, flush with water and call a doctor immediately.

    Caution

    If the ignition is in the ON position, there is potential for sparks and engagement of components. Sparks could cause an explosion, or moving parts could accidentally engage and cause personal injury.

    Ensure that the ignition switch is in the OFF position before charging the battery.

    g539045

    Figure 28

    1. 48 V system (4 batteries)
    2. 12 V system (1 battery)

    • 12 V System

      The battery voltage will be displayed on the message display if the ignition key is turned to the ON position for a few seconds. You can also use a digital voltmeter with the key in the ON position and the engine turned off. Charge the battery to bring it up to a charge of 12.1 V or greater.

    • 48 V System

      With the engine turned off and the key in the ON position, check each battery individually with a digital voltmeter. Charge each battery individually to bring it up to a charge of 12.1 V or greater. All four batteries need to be charged to a minimum of 12.1 V, and need to be within 0.3 V of each other. If any of the batteries in the pack cannot meet these requirements, all 4 batteries must be replaced at the same time.

    Important: When replacing the 48 Volt battery pack, use 4 identical Toro batteries (P/N 142-7345). Charge each battery individually to a minimum of 12.1 V and ensure each battery is within 0.3 V of each other before installing. Failure to do so will reduce the life of the battery pack.

    Important: In order to prevent damage to the battery, use an automatic 12 volt smart charger approved for use with AGM type batteries with an output of 3.5 A or less. Make sure the negative battery cable is disconnected before charging and that the charger is set to the correct mode for 12 volt AGM batteries.

    Important: For EFI machines: Unplug the harness from the ECU before performing any welding on the equipment.

    Recommended Jump Starting Procedure–

    Caution

    Corrosion or loose connections can cause unwanted electrical voltage spikes at anytime during the jump starting procedure.

    Do not attempt to jump start with loose or corroded battery terminals or damage to the engine or EFI may occur.

    Danger

    Jump starting a weak battery that is cracked, frozen, has low electrolyte level, or an open/shorted battery cell, can cause an explosion resulting in serious personal injury.

    Do not jump start a weak battery if these conditions exist.

    Caution

    Connecting the jumper cables incorrectly (wrong polarity) can immediately damage the electrical and/or EFI system.

    Be certain of battery terminal polarity and jumper cable polarity when hooking up batteries.

    Warning

    Batteries contain acid and produce explosive gases.

    • Shield the eyes and face from the batteries at all times.

    • Do not lean over the batteries.

    1. Check the weak battery for terminal corrosion (white, green, or blue “snow”), it must be cleaned off prior to jump starting. Clean and tighten connections as necessary.

    2. Make sure the booster is a good and fully charged lead acid battery at 12.6 V or greater. Use properly sized jumper cables (4 to 6 AWG) with short lengths to reduce voltage drop between systems. Make sure the cables are color coded or labeled for the correct polarity.

      Note: The following instructions are adapted from the SAE J1494 Rev. Dec. 2001 – Battery Booster Cables – Surface Vehicle Recommended Practice (SAE – Society of Automotive Engineers).

      Note: Be sure the vent caps are tight and level. Place a damp cloth, if available, over any vent caps on both batteries. Be sure the vehicles do not touch and that both electrical systems are off and at the same rated system voltage. These instructions are for negative ground systems only.

    3. Connect the positive (+) cable to the positive (+) terminal of the discharged battery that is wired to the starter or solenoid as shown in Figure 29.

      g012785
