ABSTRACT:
A trimmer comprises a cutting head (1) housing a cutter (5), and a shaft (2) for supporting the cutting head. A large diameter wheel (8) is rotatably mounted with respect to the cutting head (1), and a motor is provided for driving the cutter (5) via an output shaft (7). The cutting head (1) is connected to the shaft (2) by a joint (3) permitting the cutting head (1) to be positioned with its cutter (5) either substantially horizontal or substantially vertical. The wheel (8) is sized to contact the ground when the cutter (5) is substantially vertical and to circumscribed the axis of the output shaft (7). The arrangement is such that the cutter (5) extends beyond the circumference of the wheel (8).
