A hedge trimmer having a drive train, the drive train being arranged in use, to provide power to a downstream mechanism of the hedge trimmer, the drive train comprising:
- a motor having an output shaft;
- a pinion coupled to the output shaft;
- a single reduction gear arranged to be driven by the pinion;
- a flywheel that is engaged with the output shaft, wherein the reduction gear and flywheel are arranged within a gear housing;
- wherein the flywheel is selectively engageable and disengageable from the output shaft by axially moving the flywheel, and the flywheel's position does not affect the means by which power is delivered from the motor to the downstream mechanism.
A hedge trimmer having a drive train for powering cutting blades, the drive train comprising:
- a motor having an output shaft;
- the output shaft delivering power to the cutting blades;
- a flywheel that is engageable and disengagable from the output shaft by axially moving the flywheel, so as to selectively vary the energy provided by the motor with the output shaft;
- and
- wherein the status of the flywheel does not affect the delivery of power from the motor to the cutting blades.
