International Classification:

B60K 5/08

US Classification:

477 2, 477 3, 477 7, 180 6521

Abstract:

A vehicle hybrid drive supplies torque to an axle. The drive includes a first engine and a transmission which couples the first engine to the axle. The drive also includes a second engine, a flywheel driven by the second engine, an electric generator driven by the flywheel, a generator controller coupled between the generator and a motor controller, and an electric motor coupled to the motor controller. A gearbox is coupled between the electric motor and the axle. The vehicle drive may also include a further flywheel driven by the first engine, with the transmission being driven by the second flywheel.

Assignee:

Deere & Company - Moline IL

International Classification:

A01D 45/02

US Classification:

56104

Abstract:

A row unit comprises a row unit gearbox with two shearing edges and two stalk rolls with corresponding shearing edges, wherein the stalk roll shearing edges shear against the gearbox shearing edges when the stalk rolls rotate during normal operation of the row unit, thereby chopping material that might otherwise be wrapped around the row unit gearbox and be jammed between the stalk rolls and the gearbox.

International Classification:

G05D 13/66
B60K 31/00
B62D 55/08

Abstract:

A vehicle, method, and track control system for sensing the temperature of a track and controlling the vehicle's speed based on the temperature of the track. The track temperature may be sensed by a sensor embedded in a portion of the track, such as in a drive lug, a tread bar, or portion of the carcass. The temperature of the track may also be used to alert an operator of a track temperature issue or request that the operator reduce the speed of the vehicle.
