End-of-season maintenance protocol: Deep chassis cleaning, blade replacement, dock weatherproofing, and battery preservation.
The End-of-Season Deep Cleaning and De-Gunking Protocol
Over months of autumn mowing, damp grass clippings, wet mud, and acidic lawn juices pack into a dense green crust inside the cutting deck and around cutting disc bearings. This trapped organic matter holds moisture against motor seals, leading to bearing corrosion and motor seizure over winter. Disconnect the safety key, scrape the deck with a plastic putty knife, and clean with a stiff nylon brush (never blast with a pressure washer!).
Winter Battery Conditioning and Indoor Storage
Freezing winter temperatures will permanently degrade lithium battery capacity. Never leave your robotic mower parked outside in its charging station during winter frosts. Clean the mower, charge the battery to roughly 60% to 70% capacity, switch off the master battery power switch, and store the mower indoors in a dry basement or garage maintained between 10°C and 20°C (50°F to 68°F).
Protecting the Outdoor Charging Station and RTK Antenna
You can leave the heavy plastic charging station base outdoors, but you must unplug the AC power transformer from the wall. Coat electrical charging contact prongs with dielectric silicone grease and seal the dock in a heavy-duty waterproof winter protective storage cover. The RTK antenna can remain mounted on the roof, provided its cable entry grommets remain watertight.
Technical Specifications & Reference Matrix
| Component | Winter Action Required | Storage Location | Spring Preparation |
|---|---|---|---|
| Robotic Mower Body | Deep clean deck, dry thoroughly | Indoor heated space (15°C) | Inspect seals & install fresh blades |
| Lithium Battery Pack | Charge to 60-70% / Master switch OFF | Indoor climate-controlled | Top up to 100% before first cut |
| Charging Station Base | Unplug AC power / Grease terminals | Cover with weather bag outdoors | Polish contacts with fine sandpaper |
| Razor Cutting Blades | Discard old dull blades | Recycle old blades | Install fresh stainless blades & screws |
💡 Expert Field Recommendation
Always replace the small blade retaining screws whenever you install new razor blades in spring. Blade screws come with blue threadlocker pre-applied to ensure they do not vibrate loose under 3,000 RPM disc rotation.
Diagnostic Troubleshooting Checklist
- Charging station LED does not illuminate in spring: Corrosion on power supply pins or insect nests inside dock terminal housing. Spray electrical contact cleaner into connectors and verify power supply output voltage with a multimeter.
Frequently Asked Questions
How often should razor cutting blades be replaced during the mowing season?
Replace lightweight pivoting razor blades every 4 to 8 weeks depending on lawn size. Sharp blades slice grass cleanly like scissors; dull blades rip grass tips, causing unsightly brown lawn discoloration.
