Tiller housing
First Claim
1. An electric-powered tiller comprising:
- a frame assembly that defines a battery compartment;
an electric motor coupled to the frame assembly;
a transmission assembly coupled to the frame assembly and driven by the electric motor;
a plurality of tines driven by the transmission assembly;
a battery that is configured to be removably received in the battery compartment and electrically coupled to the electric motor to provide a source of electrical power for operating the electric motor; and
a ballast container that is configured to be removably received in the battery compartment when the battery is not received in the battery compartment, the ballast container being adapted to hold a ballast material;
wherein the battery compartment is positioned such that the weight of the battery or the ballast container is disposed over the tines when the electric-powered tiller is operated.

Abstract
A tiller includes a tiller frame and an upright assembly extending from the frame. The frame is supported by at least one wheel and defines a cavity. A transmission assembly is supported by the frame and has an output member that is configured to be drivingly coupled to a first power source in a first battery-powered configuration and to a second power source in a second electric-powered configuration. A tilling implement includes a drive shaft that is driven by the output member. The tilling implement comprises at least one tine plate. The cavity is configured to removably receive a battery in the first battery-powered configuration and removably receive a ballast in the second electric-powered configuration.
