Yarbo Y40P Lawn Mower Pro (Core + Lawn Mower Pro Module)

Yard work, handled in every season.

One Yarbo Core and swappable modules mow the lawn, clear leaves, trim the edges and blow the snow. Below: the key numbers, what each module does, and a builder to plan the setup that fits your property.

Yarbo Y40P

Your lawn, finished before breakfast.

The Y40P mows up to 2 acres a day on its own schedule and runs at about 60 dB, so an early start is realistic for most households. Swap the module and the same machine clears leaves, trims edges and blows snow.

Inside the Core

Built simpler, built to last.

Tap the numbers to see what does the work.

01

Gearbox-free dual hub motors

The motors sit inside the drive hubs, so there is no gearbox to wear out. Yarbo credits this drivetrain for the Y40P's extra speed, steadier traction and lower maintenance.

Up to 1.2 m/s

02

Binocular vision

Cameras work with ultrasonic sensors and a bumper to spot obstacles, and vision, IMU and odometry keep it on course under trees where satellite signal is weak.

Vision + IMU + odometry

03

RTK positioning and connectivity

RTK satellite positioning maps your property without a boundary wire. The Core stays connected over 4G, Wi-Fi, Bluetooth and Wi-Fi HaLow.

No buried wire

04

Tracked drive

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

Upgrade 1

More done per charge.

With the Lawn Mower Pro, the Y40P mows up to 0.3 acre per charge, 2 acres a day and 7 acres a week. With the Snow Blower it clears up to 7,000 ft² per charge. Fewer stops to recharge in the middle of a job.

Upgrade 2

Control on real terrain.

Slopes up to 70% (35°), drainage ditches, uneven ground and dense grass. The hub motors give smoother motion and faster acceleration and turning.

Upgrade 3

Fewer parts to wear.

No gearbox means fewer moving parts and less routine maintenance than a gearbox-driven machine, which matters when it runs several times a week.

Upgrade 4

Quiet enough for 7am.

At around 60 dB, what you notice is the lawn getting cut, not a motor. Early morning and evening schedules are practical for most households.

Size it

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.

Y40Up to 6 acres a week
Y40P THIS PAGEUp to 7 acres a week
Both Cores are rated for it

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 three-point steel 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 Y40P, 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?

The Y40P uses gearbox-free dual hub motors, which make it faster and more efficient than the Y40. Top speed rises from 0.6 to 1.2 m/s, mowing per charge from 0.25 to 0.3 acre, and snow cleared per charge from 6,000 to 7,000 ft². The climb rating of 70% (35°) and the noise level of about 60 dB are the same on both.

Does the Y40P 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. Add the Lawn Mower Pro, Snow Blower, Blower or Trimmer and the same Core does that job.

How much lawn can the Y40P mow?

With the Lawn Mower Pro module, the Y40P mows up to 0.3 acre per charge, 2 acres per day and about 7 acres per week at two cuts a week. It mows for about 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 modules. With the Snow Blower module, Yarbo rates it for slopes up to 36% (20°).

How loud is the Y40P?

About 60 dB, which Yarbo compares to normal conversation. That makes early morning or evening schedules practical for most households.

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 the Snow Blower and Trimmer operate from -13°F to 113°F.

Do I need to bury a boundary wire?

No. The Y40P uses RTK satellite positioning with vision, IMU and odometry, so you map your property in the app instead of digging in a wire.

Will my existing Yarbo modules fit the Y40P?

Yes. Yarbo sells the Lawn Mower Pro, Snow Blower, Blower and Trimmer as Y Series modules and publishes figures for both cores on the same module, for example 6 acres a week on the Y40 and 7 acres on the Y40P with the Lawn Mower Pro. If you own an older module, call +1 423-927-3776 and we will check it against your exact model.

What is the Yarbo Trimmer?

The Trimmer is 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 Y40P is covered by Yarbo's manufacturer 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.
