  • USER IDENTIFICATION AND CUSTOMIZATION FOR OUTDOOR POWER MACHINES
    Publication number: 20180263182
    Abstract: An outdoor power machine apparatus includes a prime mover, such as a combustion engine or an electric motor. The outdoor power machine is operable to carry out machine function, e.g. a material handling function. An electronic controller is connected to a machine function and identifies a specific user and controls the machine function based on the identity of the user. The controller may be configured to permit or deny operation of the machine function based on the user's identity. The controller may be configured to operate the machine function in a desired manner based on the user's identity.

  • Short turn radius steering system
    Patent number: 8882119
    Abstract: To reduce the complexity, maintenance, and cost, and to increase the reliability of a riding lawnmower employing a short turn radius steering system, the riding lawn mower may be configured with a linkage and steering assembly that eliminates or reduces complicated gearing. A riding lawn mower may comprise a link system, pivot brackets, and spindle assemblies. The geometry of the steering system may be configured to provide a turn radius of seven inches or less. Moreover, the geometry of the steering system may be configured to provide Ackerman steering, such that, the inside wheel turns sharper than the outside wheel in a turn.
