Product Description

The Lawn Mower Pro Module (Y Series) turns a Yarbo Core into a heavy-duty autonomous mower. Dual 300W cutting motors with up to 2500W of peak power, a 20-inch cutting width, and a cutting height that goes as low as 0.8 in make it suited to large, demanding lawns, thick or wet grass, and warm-season turf on residential and commercial properties. It ships with both standard cutting discs and optional straight blades.

Key Features

  • 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
