Abstract
A vertical tine tiller having vertically oriented tine assemblies that are configured to rotate about vertical axes is provided. The tiller includes a power source that drives a horizontally-aligned driveshaft, which can selectively drive a transmission assembly. Horizontal rotation of the driveshaft is directly transferred into vertical rotation of a pair of drive rods to which the tine assemblies are attached.
