Yarbo Core + Lawn Mower Pro Robotic Mower Bundle, Y40 or Y40P
Free shipping to the contiguous U.S.
Description
The Yarbo Core with Lawn Mower Pro is a complete tracked robot mower for a large or sloped lawn — and the Core underneath accepts every other Yarbo module when the seasons change.
For the homeowner handing over a big property, it mows, returns to its dock, recharges, and resumes where it stopped.
Shipping and Delivery
Delivery: Free within the 48 contiguous states. The order arrives in separate cartons — the Core, dock, battery, and each module — so plan for someone to be home and inspect each one before you sign.
Key Features
Y40 or Y40P: Y40P replaces the Y40's gearbox drive with gearbox-free dual hub motors. Top speed rises from 0.65 to 1.2 m/s and overall efficiency by about 15%, with less routine maintenance. The slope rating and working noise stay the same.
Positioning: The Y40 includes a Data Center, a local RTK base station that runs with no internet. The Y40P has no Data Center in the box and uses NetRTK instead, free for the life of the robot — no base station to mount, but it needs internet and coverage at your address, which the Yarbo app checks before setup.
Terrain: It handles 70% (35°) slopes and 2-inch obstacles, and keeps its position under tree cover with vision, IMU, and odometry.
Cutting: Twin 300 W motors (2,500 W peak) drive a 20-inch cutting width, with height set from 0.8 to 4.0 inches. Razor-blade discs and SK85 steel straight blades are both in the box.

What's Included
In the box: Core, docking station, battery, wired charger, tow hitch, RTK and HaLow antennas, and tool kit. The Lawn Mower Pro comes with spare blades and cutting discs. The Y40 adds a Data Center.
Installation and Compatibility
Setup: Map the yard in the Yarbo app, with no boundary wire. On the Y40, mount the Data Center with at least 120° of open sky. The Lawn Mower Pro Essential Kit pairs with this bundle as an add-on.
Later: Add the Snow Blower Gen 2, Blower and Trimmer Package to the same Core — another season is an attachment rather than another machine.
Warranty
Term: Two years for residential use, starting at app activation or three days after delivery, whichever comes first. Each module's warranty starts on its own.
Not covered: Consumables such as tracks, antennas, blades, and discs, plus commercial, professional, or rental use and non-Yarbo parts.
Claims: Yarbo Support issues an RMA before anything ships back, and Yarbo covers the freight once it is approved.
Frequently Asked Questions
What grass can it handle?
Cool- and warm-season grasses, including Zoysia, St. Augustine, Bermuda, Buffalo Grass, and Kikuyu. Very wet or overgrown grass may need a higher cut or more frequent mowing.
Which blades come with it?
Dual cutting discs with five razor blades each, plus SK85 high-carbon steel straight blades.
Who changes the modules?
You do, as the season turns. They're quick-swap by design.
What if NetRTK doesn't reach my address?
Choose the Y40, which includes a Data Center, or add a Data Center to the Y40P.
What happens if I move?
With NetRTK there's no base station to take down. You reconnect and map the new yard.

Yarbo · Modular yard robot
The mower most start with
The Core platform under the full-size Lawn Mower Pro deck — a 20-inch cut on tracks, with the rest of the module family waiting when the season turns. One box, one dock, a complete robotic mower.
* Actual coverage and runtime vary with conditions, terrain and settings.
The system
One Core. Four jobs.
Every module below runs on the same tracked body, battery, dock, and map. Swapping one for another is a driveway job — latches, not tools. The Core is bought once; the modules are the repeat purchase.

The year
Four seasons, one map
The property is mapped once. After that, the season decides the module — not another machine, another app, and another charger on the wall.
Grass
Mower decks cover about 0.25 acre per charge and up to 1.7 acres a day on a mow-and-recharge cycle. Rain detection sends it home.
Leaves
The blower module pushes 607 CFM along routes you set once — lawn, drive, and walkways cleared on a schedule.
Snow
Two-stage clearing, 24 inches at a pass, thrown up to 40 feet — rated to −13°F, on paved, concrete, or gravel drives.
Edges & errands
The trimmer arm finishes fence lines; the bare Core tows up to 500 pounds and takes teleoperation when you want the wheel. Follow-Me and Patrol need the Smart Assist Module.
Ways in
Start where the yard says

FAQ
Questions before you buy
How much lawn can it keep up with?
About 0.25 acre per charge, up to 1.7 acres a day on a mow-and-recharge cycle, and up to 6 acres maintained on a twice-a-week schedule. Your layout, growth and terrain will change those numbers.
How steep a yard can it mow?
The tracks handle 70% (35°) slopes and 2-inch vertical obstacles. Cutting height runs from 0.8 to 4.0 inches and is set from the app.
How does it sense obstacles?
With binocular cameras, ultrasonic sensing and a physical bumper. We would still keep people and pets out of the work area while it runs.
Do I need to bury a boundary wire?
No. You map the property in the Yarbo app, and the robot holds position with RTK-GPS backed by vision, IMU and odometry. Changing a boundary later is an app edit, not a digging job.
Does it need internet or a cell plan?
That depends on the generation. The Y40 includes a Data Center, a local RTK base station that reaches the robot by radio with no internet or cellular. The Y40P has no Data Center in the box and uses NetRTK, free for the life of the robot, which needs internet and coverage at your address. The Yarbo app checks coverage before setup.
Who sets it up, and where does everything go?
You do, in the Yarbo app. The box includes the docking station, antennas and an installation and tool kit. The Y40 also includes a Data Center, which needs at least 120° of open sky, ideally at the highest point on the property, and moving it later means mapping again. Yarbo also offers one-on-one video setup and a map of volunteer installers.
Can it stay outside all year?
Yes. The robot is designed to stay outside on its dock through sun, rain and snow, within its −13°F to 113°F operating range.
What is the difference between Y40 and Y40P?
The drive. Y40P replaces the Y40’s gearbox with gearbox-free dual hub motors. Top speed rises from 0.65 to 1.2 m/s, mowing from 0.25 to 0.3 acre per charge, and snow clearing from 6,000 to 7,000 sq ft per charge. The slope rating and the modules are the same.
Can I add modules later?
Yes. Each module fits both the Y40 and Y40P Core, and the Core and dock stay the same. You can buy them from us when the season changes.
What does the warranty cover?
Yarbo gives a 2-year limited warranty for residential use. Its 2026 policy excludes consumables such as tracks, antennas, blades and belts, and it excludes commercial, professional and rental use. Yarbo Support issues an RMA before anything ships back, and Yarbo covers the freight once it is approved.
Can I return it if I change my mind?
No. Yarbo equipment is returnable for product defects only, so ask us anything you are unsure about before ordering. If it arrives damaged, tell us within 48 hours. Our return policy has the details.
How is it delivered?
Free within the 48 contiguous states. It ships as large cartons, so plan for someone to be home, and inspect the cartons before you sign.
Before you order
Plain talk, as usual
The trimmer is a pre-order
Estimated delivery for the Trimmer Package is January 2027. The rest of the order ships ahead of it.
Positioning comes first
The Y40’s Data Center needs a clear view upward. The Y40P has none in the box and uses NetRTK, which needs internet and coverage at your address. Vision, IMU, and odometry carry the robot under trees. Coverage and runtime vary with your terrain, so tell us about it first.
It arrives as freight
This is not a parcel-locker purchase — the Core and modules ship as large cartons (the snow blower module alone is about 77 pounds). Plan for someone to be home, and read the delivery band on our shipping policy before ordering.
