This document is the Operator's Manual for the Toro eTimeCutter® 42in or 54in Riding Mower, models 75841 and 75851 (Serial Range 400000000 and Up). It provides comprehensive information on the safe operation and maintenance of the machine.

Function Description:

The Toro eTimeCutter® riding lawn mower is a rotary-blade, battery-operated machine intended for residential use by homeowners. Its primary function is cutting grass on well-maintained lawns. It is designed for maneuverability, featuring independent drive wheels powered by motors on each axle, allowing for tight turns and even spinning. The mower is equipped with a blade-control switch (PTO) to engage and disengage the mower blades and a traction-speed switch to select faster or slower ground speeds. MyRide® suspension models offer an adjustable seat suspension for enhanced comfort.

Usage Features:

Control Panel: Features a key switch (On/Off/Start), blade-speed switch (Fast/Slow), traction-speed switch (Fast/Slow), blade-control switch (PTO), and an information display.
Information Display: Shows interlock indicators, motor status (during active faults), battery status/charge, and operating hours. It also displays icons for operator presence, PTO engagement status, parking brake status, motion-control lever position, battery/motor temperature, battery/motor load, limp mode, and fault codes.
Key Switch: Powers the machine On/Off and starts the machine.
Traction-Speed Switch: Allows selection of faster or slower ground speeds.
Blade-Speed Switch: Allows selection of faster or slower blade speeds (FAST for best cutting, SLOW for less energy consumption).
Blade-Control (PTO) Switch: Engages and disengages power to the mower blades.
Parking Brake: Engaged by pushing the pedal down and moving it left into the detent; disengaged by pushing down, moving right, and slowly releasing. Used to prevent accidental movement and for emergency stops.
Motion-Control Levers: Used to drive the machine forward, reverse, and turn. Moving one lever farther than the other facilitates turning.
MyRide® Suspension Adjustment Lever: (MyRide models only) Adjusts seat suspension for comfort.
Seat Adjustment: The seat can be positioned for operator comfort.
Motion-Control Lever Height/Tilt Adjustment: Levers can be adjusted higher/lower and tilted forward/rearward for ergonomic comfort.
Side Discharge: Hinged grass deflector disperses clippings to the side and down toward the turf.
Height of Cut Adjustment: Lever-based adjustment for cutting height.
Anti-Scalp Rollers: Adjustable to match the height-of-cut position, preventing scalping on uneven ground.
Operating Tips: Includes recommendations for maximizing air circulation, avoiding cutting too low, cutting only a third of the grass blade, alternating mowing direction, and maintaining a clean mower deck.
Battery Charging: Batteries are charged using the provided charger. The charger indicates charging status (off, yellow for standby, green blinking for charging, green for fully charged, red for temperature range issues, red blinking for charging fault). Two charging modes are available: serial (Mode A) and parallel (Mode B).
Hauling: Instructions for safely loading and tying down the machine on a trailer or truck, emphasizing the use of full-width ramps and adherence to slope limits (not exceeding 15 degrees).

Maintenance Features:

Daily Maintenance: Includes checking lug-nut torque, safety-interlock system, blades (for wear/damage), and grass deflector. Cleaning grass and debris from the machine.
Every 25 Hours: Check battery box filter (replace if needed).
Yearly: Check lug-nut torque.
Before Storage: Perform all listed maintenance procedures, charge batteries (2-3 LEDs green for off-season storage), scrape grass/dirt from mower underside, check blade condition, check/tighten fasteners, paint scratched surfaces, and store in a clean, dry area with the key removed.
Electrical System Maintenance: Instructions for preparing battery packs for recycling (covering terminals with tape, not disassembling).
Battery-Box Filter: Located behind the seat, can be cleaned by tapping or replaced if dirty/damaged.
Tire Pressure Check: Maintain specified air pressure in front and rear tires for even cut.
Wheel Lug Nuts: Check and torque to 108 N·m (80 ft-lb).
Tracking Adjustment: Procedure to adjust machine tracking if it pulls to one side when driving forward at full speed.
Mower-Deck Maintenance:
- Blade Service: Keep blades sharp; replace if bent, unbalanced, or damaged. Instructions for inspecting, removing, sharpening (maintaining original angle and balance), and installing blades (curved part pointing upward, torque to 81-108 N·m).
- Checking for Bent Blades: Procedure to measure blade tip distance from a level surface at 180-degree rotation; replace if difference exceeds 3 mm (1/8 inch).
- Leveling the Mower Deck: Detailed procedure involving setting anti-scalp rollers, height-of-cut, placing blocks under the deck, and adjusting side-to-side and front-to-rear levels using adjustment nuts and plates.
Brake Maintenance: Testing the parking brake to ensure it stops the machine and the icon displays correctly.
Cleaning: Cleaning under the mower deck after each use to prevent grass buildup. Emphasizes not using water on the mower deck to avoid damaging electric motors. Recommends using compressed air with appropriate PPE for cleaning.
Troubleshooting: Comprehensive tables for machine, battery, charger, and display error/fault code troubleshooting, including possible causes and corrective actions. Fault codes are structured to identify the system (PMU, Primary Controller, Traction/Blade Motor Controller) and specific fault.
