ROBOTIC LAWN MOWER COMPRISING A SKID PLATE

Patentradars sammanfattning

Husqvarna's invention addresses scalping on uneven terrain (e.g., golf course fairways) by providing a shallow bowl-shaped skid plate mounted below the cutting disk of a robotic mower. The circular plate's edge portion is bent transversally with a circle-segment cross-section (radius 1–30 mm), eliminating sharp edges that could dig into the ground, while its outer peripheral edge lies in a single plane. A central offset portion, co-planar with that outer edge, forms a socket that fully recesses the hub and fastening hardware, allowing knife attachment means to extend below the peripheral edge level and thereby position the knives extremely close to the ground. The skid plate is connected via a bearing so it does not rotate with the cutting disk, and pivotably mounted knives further reduce scalping risk.
