The invention discloses a rolling protection system for a riding type mower. The rolling protection system comprises a protection device and a protection triggering device. The protection device comprises fixed rods vertically arranged at two sides of a mower chassis, wherein sleeve rods are arranged at the outer sides of the fixed rods in the same direction; an electric control state keeping assembly is arranged at one sides of the sleeve rods; a push rod is arranged in each sleeve rod in a sleeved mode; a spring is arranged at one end, stretching into a sleeve rod, of each push rod; and thetop parts of two push rods are connected through a top-part support. The protection triggering device is arranged on a mower; the protection triggering device is connected with the electric control state keeping assembly; the protection triggering device obtains the stable state of the mower and generates a protection signal according to the stable state; and the electric control state keeping assembly releases fixing of the push rods on the basis of the protection signal. The rolling protection system provided by the invention has a telescopic characteristic, so the structure is compact; installation is reliable; noise is avoided; meanwhile, obstacles like tree branches can be easily avoided at a low height; and operation can be more conveniently carried out in a forest land.
