Does your Worx Landroid robotic mower sometimes slip or struggle on wet grass or slopes? These stainless steel traction spikes are the simple upgrade to give it some serious grip! This set includes two spikes (one for each rear wheel), each measuring 205mm in diameter and 2mm thick. They're made from high-quality, polished stainless steel, so they're rust-proof and built to last through seasons of mowing. They're compatible with a wide range of Worx Landroid S and M series models – we've listed the compatible model numbers in the description, so please double-check yours fits (e.g., WR130E, WR165E, WR142E, etc.). Installation is straightforward: you center the spike over the wheel and secure it with the six included Torx screws per spike (12 total screws are provided). Once on, they provide much better traction, helping your mower climb inclines and navigate damp lawns without slipping or, more importantly, without digging unsightly holes into your turf. It's a small add-on that makes a big difference in performance and helps keep your lawn looking perfectly manicured.
