Tired of your Husqvarna Automower getting stuck or digging up your lawn? These stainless steel spikes can help! Designed specifically for Automower models like the 330, 420, 430X, 435X, 440, 450X, 435X AWD, and 550 with 252mm wheels, they give your mower much better traction, especially on wet grass or sloped yards. Made from polished stainless steel, they're rust-proof and built to last. Installation is super simple: just center each spike on the wheel and secure it with the included screws (12 screws total). The deburred edges and countersunk screw holes give a clean, professional look. With better grip, your mower won't spin its wheels or leave holes, so your lawn stays beautiful. A must-have accessory for any Automower owner!
