WORX Landroid WR155: Replacement Blades, Battery, Parts and Accessories
Older-model ownership file: The WORX Landroid WR155 represents the large-lawn boundary-wire generation that remains in service and therefore has meaningful replacement-part demand. Yard Robot Lab has not physically tested this mower.
Parts documented for the WR155
The official WR155-family manual identifies the mower’s battery pack as WA3671 and documents the charging station, power supply, boundary wire and connectors as system components. Because production revisions can matter, owners should still verify their mower label before ordering electrical parts.
Replacement blades
WORX currently lists the Landroid Long-Life Replacement Blades (WA0789) in its Landroid accessory catalog. WORX’s blade-change guidance says that if one blade is replaced, all blades should be replaced as a set.

Boundary-wire ownership
Unlike newer wire-free systems, an older Landroid installation includes another class of service item: boundary wire and connectors. Damage from landscaping, aeration or yard work can create repair demand even when the mower itself is healthy.
Affiliate strategy later
YRL will eventually connect each verified part to suitable purchase sources. The editorial record will remain separate from the merchant link so an unavailable retailer can be replaced without changing the compatibility research.
