A brush cutter work head (20) has a protective shroud (36) with a vertical side opening (40) to expose a portion of a circular cutting blade (42) to enable the blade (42) to cut brush. A spray nozzle (82) is mounted on a sliding member (74) that slides within a tubular housing (58) incorporated into the work head housing (28). The sliding member (74) has a retracted position in which the nozzle (82) is positioned above a portion of the housing (28), and a projecting use position in which the nozzle (82) is aligned with the opening (40) above and outward of the blade (42). A gripping thumb (44) is pivotally mounted on the work head housing (28) and is operated by an actuator (52) within the housing (28) to pivot between a flush nonuse position and a gripping position in which it opposes a jaw (38) formed by a lower portion of the shroud (36). |
