The Makita Genuine 1913N2-4 Boundary Wire Set is the correct OEM replacement perimeter wire for the Makita RM350D robotic lawn mower, supplied as a 150-metre reel. This is the same boundary wire included with the RM350D as standard, ensuring complete compatibility with the mower’s signal and navigation system from the moment it is installed. Whether setting up a new installation or extending an existing one, using genuine Makita wire eliminates any risk of signal interference or detection errors that can arise with non-OEM alternatives. The boundary wire defines the outer perimeter of the mowing area, preventing the RM350D from straying beyond the lawn’s boundaries. The same wire can also be used as a guide wire, directing the mower from the charging station into specific zones — particularly useful for gardens with narrow passages, separate lawn sections, or areas that require consistent coverage. The RM350D supports up to two guide wires alongside the main boundary loop. This replacement set is suitable for a range of practical situations: installing the RM350D without wire, expanding the mowing area following garden changes, relaying wire after landscaping or groundworks, or replacing wire that has been cut or damaged.
