Overview
Reliable boundary-wire mowing for Up to 0.25 acres coverage
Full Review
The Robomow RK4000 covers up to Up to 0.25 acres using Boundary Wire navigation with traditional boundary wire installation. It handles slopes up to 20° with its 2WD drive system and features a 16.1 in cutting width.
You'll need to install boundary wire around your mowing area before first use — plan for a few hours on smaller yards, or a full day for larger properties. Once installed, the system is reliable and the mower operates autonomously within the defined boundaries.
Key features include Wide deck, tall grass (up to 4 in), staggered blades. At $1,500–$2,000, the RK4000 competes in a crowded boundary-wire market where wire-free alternatives are increasingly compelling.
