ABSTRACT:
A primer mower (A) has an articulated boom assembly (B) connected to it. A mower head (C) is connected with the other end of the boom assembly. This enables the mower head to be positioned substantially parallel with the ground even along embankments and the like. The mower head includes a deck (20) and a downward extending skirt (22). A rotary cutter (16) is rotatably disposed below the deck and extends outward there beyond at a cutter exposing opening (24). A guard assembly (30) is moveably disposed across the cutter exposing opening for selectively exposing the cutter to permit the cutter to strike saplings and the like. One embodiment of the guard assembly includes a first guard member (32) connected by a pivot (38) to the deck and having a cutter exposing opening (44) therein. A second guard member (50) is connected by a pivot (58) with the first guard member. Springs (72 and 74) bias the first and second guard members such that the cutter exposing opening is covered until the guard assembly is impacted with sufficient force to overcome the bias force and expose the cutter. In another embodiment, the guard assembly is biased across the cutter exposing opening by a hydraulic cylinder (90, 110) and associated hydraulic circuitry.
