Product Description

Pre-order notice: This bundle includes the Yarbo Trimmer and Back Brace Mount, which Yarbo currently lists as pre-order items with estimated delivery around January 2027. Yarbo also notes that the Trimmer is still in extended field testing and performance calibration. Delivery dates are Yarbo's estimates and may change.

This bundle pairs the Yarbo Y40 Core with the Lawn Mower Pro Module and the Trimmer Package (Yarbo Trimmer, Back Brace Mount, and a BBM-compatible tow hitch) for autonomous mowing plus hands-free edging. All items ship together.

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

Trimmer Package

  • What the package is: the Yarbo Trimmer plus the Back Brace Mount (BBM) and a tow hitch designed to work with the BBM; the Trimmer connects to the Yarbo Core only through the BBM
  • Hands-free trimming: no need to hold or guide a trimmer; set it and let the robot trim along edges
  • Memory path: the robot follows the edge path you draw, repeating the same lines for a consistently trimmed look
  • Automatic line feed: uninterrupted trimming, with line replacement needed about once a month on average depending on lawn size and use
  • Smart terrain adaptation: spring and floating-ball suspension lets the head bounce back from obstacles and follow uneven ground for more consistent cuts
  • Adjustable trimming height: 2 to 4 in
  • Smart obstacle response and wireless auto-recharging for low-maintenance upkeep
  • Back Brace Mount: all-steel, three-point mount that also expands towing to rolling loads up to 3,500 lbs with up to 200 lbs tongue weight, and works with the Core in Tow Mode

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