Abstract

A starter device for a work machine may include a ring switch surrounding a housing. The ring switch may be rotatable between a first ring position and a second ring position. A push button may be surrounded by the housing and may be operatively engageable between a first button position and a second button position within the housing. A controller may be in communication with the ring switch and the push button. The controller may be configured to start a prime mover of the work machine when the ring switch is in the second ring position and the push button is operatively engaged from the first button position to the second button position. The controller may be configured to stop the prime mover using delayed shutdown when the ring switch is rotated from the second ring position to the first ring position.

Claims7

Dependent claims

A method for starting and stopping a prime mover of a work machine, the method comprising:

powering on a controller when a ring switch is rotated from a first ring position to a second ring position;
authenticating an authentication input received from an input device;
starting the prime mover independently from engagement of a brake pedal of the work machine when the authentication input is determined to be correct, the ring switch is in the second ring position, and a push button is engaged;
determining, by the controller, when the ring switch is rotated from the second ring position to the first ring position, whether to stop the prime mover immediately or to stop the prime mover using a delayed shutdown procedure;
beginning the prime mover delayed shutdown procedure, such that the prime mover continues running for a period of time before stopping;
and
bypassing the delayed shut down procedure and stopping the prime mover immediately when the push button is engaged for a predetermined period of time.
