A vegetation cutting tool, such as a line trimmer (10) includes a motor (21) that drives a cutter (16), both of which are supported in a head (11) of the tool. A pivot (25a, 25b) is disposed between the head (11) and a shaft (14) of a handle, for pivotably mounting the head to the handle. Angularly spaced first and second recesses (51. 52) in the head are provided for receipt of the latch (31). A bias member (32) biases the latch (31) into engagement with the first recess (51) upon rotation of the head into the trimming position, and biases the latch (32) into engagement with the second recess (52) upon rotation of the head into the edging position. Resilient means (65) connected between the head (11) and the shaft (14) for applying torque to rotate the head (11) relative to the shaft (14), away from the first position toward the second position. |
