Product Description

This package pairs the Yarbo Y40 Core with the Lawn Mower Pro Module for autonomous mowing of large, demanding properties up to 6 acres. The Core supplies navigation, power, and self-charging, while the Lawn Mower Pro adds dual 300W cutting motors, a 20-inch cut, and a choice of standard cutting discs or straight blades. The Core and module ship together, and more modules can be added later.

Yarbo Y40 Core

  • 500 lbs towing capacity and slope handling up to 70% (35°) on high-traction tracks
  • RTK-GPS, IMU, odometry, and binocular-camera navigation with smart object detection
  • Included Data Center works as a local RTK base station by radio for centimeter-level accuracy without internet or cellular service
  • App control on iOS and Android with schedules, zone mapping and alerts, and yard live view
  • Wireless auto-recharging, IPX5 water resistance, rain detection, and operation from -13°F to 113°F (-25°C to 45°C)
  • Connectivity: 4G, Wi-Fi, Bluetooth, and Wi-Fi HaLow; battery: 36 V 38.4 Ah; charging (20%–80%): 90 min

Lawn Mower Pro Module

  • Dual 300W cutting motors: twice the power of the standard 150W mower motors, with up to 2500W peak power for thick, wet, dense, or overgrown grass
  • Two blade systems: standard dual cutting discs, each carrying 5 reinforced razor blades, plus optional straight blades made from SK85 high-carbon steel
  • Straight-blade benefits: finer clippings that break down faster to feed the lawn, greater durability with fewer replacements, and smoother, lower-vibration mowing
  • Less clogging: blades rotate outward to eject clippings and the simplified deck helps prevent buildup, so mowing continues without mid-task stalls
  • Wide coverage: 20 in (500 mm) cutting width and properties up to 6 acres on the Y40 (7 acres on the Y40P)
  • Low cutting height: adjustable from 0.8 to 4.0 in (20–102 mm), with reinforced blades that press deeper into dense turf
  • Grass versatility: suited to residential and commercial use on cool- and warm-season grasses, including Zoysia, Buffalo Grass, St. Augustine, Bermuda, and Kikuyu
  • Autonomous operation: plans routes, mows, and returns to charge on its own, with quiet operation and app control
  • Simple upkeep: tool-free blade replacement, recommended about every 3 months under heavy use

Certain features of the Yarbo Core require the Smart Assist Module, which is sold separately.

Mowing Made So Much Easier.

I'm pleased with the navigation technology and how it's handled the lawn without traditional mowing routines!

A Huge Time Saver.

Yarbo has been a great purchase for making yard maintenance easier. I especially like the hands-off approach and how much time it could save.
