Tap the numbers to see what does the work.

01

Stereo vision and RTK

Stereo vision and RTK positioning map your property in the app, so there is no boundary wire to bury. Yarbo's Data Center sets up a local RTK base station for centimeter-level accuracy.

No buried wire

02

High-traction tracks

Rubber tracks grip slopes up to 70% (35°), thick grass and uneven ground that stop many wheeled robots.

03

Wireless auto-recharging

When the battery runs low it drives back to the dock and charges wirelessly, then carries on with the job.

90 min, 20 to 80%

04

Quick-swap module mount

The Lawn Mower Pro, Snow Blower, Leaf Blower and Trimmer all attach to the same Core, so one machine covers the whole year.

Fall

Leaves off the lawn.

The Leaf Blower Module moves 174 mph air at 607 CFM across lawns, drives and paths, on slopes up to 70% (35°).

Winter

The driveway, cleared.

The 2-stage Snow Blower clears a 24 inch path and throws snow 6 to 40 feet, up to 6,000 ft² per charge at 1 inch of snow, from -13°F to 113°F.

All season

Clean edges.

The Trimmer finishes the strip along fences, walls and beds that a mower leaves behind. It connects through the Back Brace Mount in the Trimmer Package.

Y40 or Y40P?

Same system, two cores.

Both cores take the same Y Series modules and climb the same 70% (35°) slopes. The Y40P adds gearbox-free hub motors for more ground per charge. Book an assessment and we will tell you honestly which one your property needs.

How much lawn is yours?

Slide to the area of grass you mow, not the whole lot. The gauge shows it against Yarbo's weekly ratings for each Core.

Y40 THIS PAGEUp to 6 acres a week
Y40PUp to 7 acres a week

Yarbo rates the Y40 at up to 6 acres a week and the Y40P at up to 7, at two cuts a week. Ask us about your yard

Yarbo ratings at two cuts a week. Slopes up to 70% (35°); steep or broken ground can lower real coverage.

One Core, four jobs

Pick the job. Swap the module.

Every module snaps onto the same Core. When the season changes, you change the module and the Core keeps its map of your property.

Yarbo Back Brace Mount

Trimmer Package (Y Series)

Meet the Yarbo Trimmer.

Mowing leaves a line of grass along every fence post, wall and flower bed. The Trimmer takes care of that line, so the lawn looks finished without anyone walking the edges with a string trimmer.

  1. Back Brace Mount. A mount on the back of the Core. The Trimmer only connects through it.
  2. Trimmer head. A 200 W motor spins the line at 6,500 RPM and trims from 2 to 4 inches high, for about 135 minutes per charge.
  3. Tow hitch included. The package also ships with a tow hitch made to work with the Back Brace Mount.

$1,200

The Trimmer Package includes the Trimmer, the Back Brace Mount and a matching tow hitch.

Questions before you buy

Yarbo Y40, answered.

Still deciding? Call +1 423-927-3776, 9am to 5pm EST, or book a free property assessment.

What is the difference between the Y40 and the Y40P?

Both take the same Y Series modules and climb slopes up to 70% (35°). The Y40P adds gearbox-free hub motors: top speed goes from 0.6 to 1.2 m/s, weekly mowing from about 6 to 7 acres, and snow per charge from 6,000 to 7,000 ft². If the Y40's numbers cover your property, it is the lower-cost way into the system.

Does the Yarbo Core work on its own?

No. The Core is the base: drive, battery and navigation. It needs a module to mow, blow or clear snow. The bundles include the Core and one or more modules, so they are ready to run.

How much lawn can the Y40 mow?

With the Lawn Mower Pro, up to 0.25 acre per charge, 1.7 acres a day and about 6 acres a week at two cuts. It mows for up to 120 minutes per charge, then docks and recharges on its own.

How steep a slope can it handle?

Up to 70% (35°) with the Lawn Mower Pro, Blower and Trimmer. With the Snow Blower, Yarbo rates it for slopes up to 36% (20°).

Can it work in rain and cold?

The Lawn Mower Pro is rated IPX6 and has rain detection. The Snow Blower, Blower and Trimmer are rated IPX5, and Yarbo lists an operating range of -13°F to 113°F.

Do I need to bury a boundary wire?

No. The Core uses RTK and stereo vision positioning, and Yarbo's Data Center sets up a local RTK base station. You map your property in the app instead of digging in a wire.

What is the Smart Assist Module?

Yarbo notes that certain features need the Smart Assist Module, which is sold separately. Call +1 423-927-3776 and we will tell you whether your plans need it.

Can I add modules later?

Yes. Every module is a Y Series module, so you can start with one and add the Snow Blower, Blower or Trimmer to the same Core when you are ready.

What is the Yarbo Trimmer?

A module that edges along fences, walls and beds where the mower cannot reach. It connects to the Core through the Back Brace Mount, which comes in the Trimmer Package with a tow hitch.

What support do I get after I buy?

Every Yarbo is covered by Yarbo's 2-year limited warranty, and our team is at +1 423-927-3776, 9am to 5pm EST, or Support@yardautomationpros.com. We help with app setup, mapping and warranty claims with Yarbo.
