Abstract
A transmission for a trimmer/mower can be easily mounted onto a bearing housing of a trimmer/mower. The trimmer/mower has a vertically extending drive shaft and the transmission has a worm gear drive assembly that is drivingly connected to the drive shaft to provide an output shaft extending substantially horizontally. The worm gear drive assembly enables speed reduction and torque conversion that increases the speed of rotation and torque of the output shaft as compared with that of the input shaft. Attachments to be used on the trimmer/mower that operate in a substantially vertical plane can be mounted on the output shaft. Further, existing trimmer/mower can be retrofit with a bearing housing to which the transmission can be quickly and easily mounted. The mounting of the transmission onto the bearing housing can be accomplished without the need for tools by providing a twist-on mounting arrangement with a rotation prevention lock having a simple construction.
