Maintenance
Warning
Failure to properly maintain the machine could result in premature failure of machine systems, causing possible harm to you or bystanders.
Keep the machine well maintained and in good working order as indicated in these instructions.
Note: Determine the left and right sides of the machine from the normal operating position.
Maintenance Safety
-
Before you leave the operator’s position, do the following:
-
Park the machine on a level surface.
-
Disengage the cutting unit(s).
-
Ensure that the traction is in neutral.
-
Engage the parking brake.
-
Shut off the machine and remove the key (if equipped).
-
Wait for all movement to stop.
-
-
Allow machine components to cool before performing maintenance.
-
If possible, do not perform maintenance while the machine is running. Keep away from moving parts.
-
If the machine must be on to perform a maintenance adjustment, keep your hands, feet, clothing, and any parts of the body away from the cutting unit, attachments, and any moving parts. Keep bystanders away.
-
Clean grass and debris from the cutting unit, drive, motor, and battery to help prevent fires.
-
Keep all parts in good working condition. Replace all worn, damaged, or missing parts and decals. Keep all hardware tight to ensure that the machine is in safe working condition.
-
Check the grass catcher components frequently and replace them when necessary.
-
To ensure safe, optimal performance of the machine, use only genuine Toro replacement parts. Replacement parts made by other manufacturers could be dangerous, and such use could void the product warranty.
-
If major repairs are ever needed or if assistance is desired, contact an authorized Toro distributor.

Pre-Maintenance Procedures
Preparing the Machine for Maintenance
Warning
While you are maintaining or adjusting the machine, someone could start the machine. Accidentally starting the machine could seriously injure you or other bystanders.
Release the traction bail, engage the parking brake, remove the key, and disconnect the battery before you do any maintenance.
Perform the following before servicing, cleaning, or making any adjustments to the machine:
-
Park the machine on a level surface.
-
Engage the parking brake.
-
Shut off the machine.
-
Wait for all moving parts to stop before servicing, storing, or making repairs.
-
Disconnect the battery by pulling the T-handle connector off of the main-power-supply connector (Figure 30).
Electrical System Maintenance
Electrical System Safety
-
Disconnect the battery before repairing the machine.
-
Charge the battery in an open, well-ventilated area, away from sparks and flames. Unplug the charger before connecting or disconnecting the battery. Wear protective clothing and use insulated tools.
Servicing the Battery Pack
The only user serviceable parts in the battery pack are the labels. If you attempt to open the main compartment of the battery pack or the master controller you will void your warranty. If you are having problems with your battery pack, contact your authorized Toro distributor for help.
Warning
The battery pack contains high voltage which could burn or electrocute you.
-
Do not attempt to open the battery pack.
-
Do not place anything in the connector of the battery pack other than the wire harness connector that came with the product.
-
Use extreme care when handling a battery pack with a cracked case.
-
Only use the charger designed for the battery pack
Disposing of the Battery
The lithium-ion battery must be disposed of or recycled in accordance with local and federal regulations.
Maintaining the Battery Charger
Important: All electrical repairs should be performed by an authorized Toro distributor only.
The operator can perform very little maintenance other than protecting the charger from damage and weather.
Maintaining the Battery-Charger Cords
-
Clean the cords with a slightly damp cloth after each use.
-
Coil the cords when not in use.
-
Periodically examine the cords for damage, and replace them when necessary with Toro-approved parts.
Cleaning the Battery-Charger Case
Clean the case with a slightly damp cloth after each use.
Replacing Fuses
If the machine does not turn on, even after charging, check the machine fuses as follows:
-
Turn off the machine and disconnect the battery pack.
-
Remove the 4 screws (Figure 31) that secure the battery-pack cover and remove the cover.
-
Check the fuses in the fuse block (Figure 32).
-
If any fuse is blown, replace them with a fuse of the appropriate voltage and amperage. Refer to the traction unit Service Manual for specific fuse part numbers.
Important: All fuses on the machine are rated for 80 V. Do not use 12 V automotive fuses.
Acknowledging the Battery Interface Panel
An interface panel on the battery emits lights that indicate the battery state, including charging status, state of charge, faults, and battery updates. Refer to your authorized Toro distributor for more information about the battery interface panel.
Drive System Maintenance
Changing the Transmission Fluid
Maintenance Service Interval | Maintenance Procedure |
---|
Note: Refer to Figure 33 for this procedure.
![g340874](media/images/g340874.png)
-
Remove the breather vent and adapter assembly from the transmission.
-
Have an assistant tip the machine backwards and place a pan under the transmission.
Note: Use the pan to collect the transmission fluid.
-
Remove the drain plug from the transmission and let the fluid drain out.
-
Install the drain plug.
-
Torque the drain plug to 4 to 5 N∙m (32 to 42 in-lb).
-
Add 473 ml (16 fl oz) of Dexron VI synthetic transmission fluid through the adapter vent.
-
Install the breather vent and adapter assembly and tighten it to 12 to 15 N∙m (110 to 130 in-lb).
Controls System Maintenance
Adjusting the Service/Parking Brake
Adjust the service/parking brake if it slips during operation.
-
Disengage the parking brake.
-
Measure the free play at the end of the parking-brake handle (Figure 34).
The handle free play should be between 12.7 to 25.4 mm (0.50 to 1 inch). If the free play is not within this amount, proceed to step 3 to adjust the brake cable.
-
Perform the following steps to adjust the brake-cable tension:
-
To increase the cable tension, loosen the front-cable jam nut and tighten the rear jam nut (Figure 35). Repeat step 2 and adjust the tension if necessary.
-
To decrease the cable tension, loosen the rear jam nut and tighten the front-cable jam nut (Figure 35). Repeat step 2 and adjust the tension if necessary.

Cutting Unit Maintenance
Blade Safety
-
Use care when checking the reel cutting-unit. Wear gloves and use caution when servicing the reel.
-
A worn or damaged blade or bedknife can break, and a piece could be thrown toward you or bystanders, resulting in serious personal injury or death.
-
Inspect the blades and bedknives periodically for excessive wear or damage.
-
Use care when checking the blades. Wear gloves and use caution when servicing them. Only replace or backlap the blades and bedknives; never straighten or weld them.
-
When servicing the blades, be aware that you can still move the blades after you disconnect the power.
Installing the Cutting Unit (Models 04835 and 04845)

Cleaning
Cleaning the Machine
Maintenance Service Interval | Maintenance Procedure |
---|---|
After each use |
|
After each use, wash the machine with mild detergent and water. Do not pressure wash the machine. Avoid excessive use of water, especially near the shift-lever plate, the InfoCenter, the power center, and the machine power connector. Clean the motor to provide proper cooling during operation. Also, keep the battery pack as clean as possible so that it maintains a white color. This reflects sunlight and keeps the battery from overheating in the sun.
Important: Do not use brackish or reclaimed water to clean the machine.
Important: Always store or park the machine out of direct sunlight, as heating from the sun reduces the battery-pack life span.
