1. A vehicle including:
- at least one ground engaging member;
a frame supported by the at least one ground engaging member;
an auxiliary power system;
a work attachment coupled to the frame and powered by the auxiliary power system;
a controller operative to control at least one operation of the work attachment;
an operator area supported by the frame and including an operator seat, the operator seat including a seat cushion and a rigid plate positioned in an interior of the seat cushion between a top surface of the seat cushion and a bottom surface of the seat cushion, the seat cushion having a height, a width, and a length, the plate extending across a majority of at length and the width of the seat cushion; and
a seat switch coupled to the operator seat and configured to detect a position of the plate, the controller being in communication with the seat switch to detect at least one of an unloaded state and a loaded state of the operator seat based on the position of the plate, the controller being operative to disable an operation of the work attachment in response to detecting the unloaded state of the operator seat.

14. A method operating a vehicle, the vehicle including a power system, a work attachment powered by the power system, and an operator seat including a seat cushion, the method including:
-
detecting, by a controller of the vehicle, a position of a plate coupled to the seat cushion based on output from a sensor, the plate being positioned in an interior of the seat cushion; calculating, by the controller, a force on the operator seat based on the detected position of the plate; comparing, by the controller, the calculated force to a threshold force; determining, by the controller, an unloaded state of the operator seat based on the calculated force being less than the threshold force; and disabling, by the controller, an operation of the work attachment in response to determining the unloaded state of the operator seat. - View Dependent Claims (15, 16)

17. A vehicle including:
-
at least one ground engaging member; a frame supported by the at least one ground engaging member; a work attachment coupled to the frame; a controller operative to control at least one operation of the vehicle; an operator area supported by the frame and including an operator seat, the operator seat including a seat cushion and a rigid plate positioned in an interior of the seat cushion between a top surface of the seat cushion and a bottom surface of the seat cushion, the plate extending substantially to an edge of the seat cushion; and a seat sensor coupled to the operator seat and configured to detect a position of the plate, the controller being in communication with the seat sensor to detect at least one of an unloaded state and a loaded state of the operator seat based on the position of the plate, the controller being operative seat. - View Dependent Claims (18, 19, 20, 21)
