Abstract
A rotary mower is mounted onto a skid steer loader through a four bar linkage on each side of a mower housing. The linkage is arranged to pivot relative to a mounting bracket on the skid steer loader and relative to a mower housing, with differential lengths between upper and lower sets of links of the four bar linkage. The upper link on each side of the mower is slidably connected to the mower housing to permit the mower housing to pivot a limited amount about a traverse axis during normal operation. The links include stop members that engage when the mower is raised a selected amount to stop relative movement between the links and also to shut off power to the motor driving the mower. The forward end of the housing has depending chains mounted with a channel and providing a shield.
