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.
Claims13
A vertical tine tiller comprising:
- a frame;
- an operator control assembly extending from said frame;
- a power source for generating a rotational output, said power source operatively connected to said frame;
- a transfer casing operatively connected to said frame, said transfer casing being a single member;
- a tiller assembly being rotatably driven by said power source, said tiller assembly including a horizontally rotatable driveshaft operatively connected to power source, a pair of vertically-oriented drive rods rotatable about separate vertical axes and operatively connected to said driveshaft, and a vertically-oriented tine assembly operatively connected to each of said drive rods;
- and
- a transmission assembly in direct engagement with said driveshaft within said transfer casing for driving said transmission assembly, wherein said transmission assembly is selectively actuatable;
- wherein horizontal rotation of said driveshaft is directly transferred into vertical rotation of said drive rods within said transfer casing;
- and
- wherein a portion of said driveshaft and a portion of each of said pair of drive rods being disposed within said transfer casing, and rotation of said driveshaft is transferred to said drive rods within said transfer casing.

A vertical tine tiller comprising:
- a frame;
- an operator control assembly extending rearwardly from said frame;
- a power source for generating a rotational output, said power source operatively connected to said frame;
- a driveshaft operatively connected to said power source for receiving said rotational output therefrom;
- a transfer casing operatively connected to said frame, said transfer casing being a single member;
- a tiller assembly operatively connected to said frame wherein said tiller assembly extends rearwardly from said frame, said tiller assembly being rotatably driven by said power source, said tiller assembly including a pair of vertically rotatable drive rods, and a tine assembly operatively connected to each of said drive rods, wherein each of said tine assemblies being rotatable about a substantially vertical axis;
- a transmission assembly in continuous and direct engagement with said driveshaft, wherein said transmission assembly is selectively actuatable;
- a pair of rotatable wheels operatively connected to said frame, said pair of wheels being selectively driven by said transmission assembly;
- wherein a portion of said driveshaft, a portion of each of said pair of drive rods, and a portion of said transmission assembly are positioned within said transfer casing, and rotation of said driveshaft is transferred to said drive rods and said transmission assembly within said transfer casing.
