Abstract
A mower including a handle assembly, a grip moveable relative to the handle assembly, a sensor operable to generate an output signal based on a position of the grip relative to the handle assembly, a drive assembly, and a controller coupled to the sensor and the drive assembly. The controller receives the output signal and controls the drive assembly according to the output signal.
Claims20
A mower comprising:
- a handle assembly including a cross member;
- a grip moveable longitudinally relative to the cross member;
- a sensor operable to generate an output signal based on a position of the grip relative to the cross member;
- a drive assembly;
- and
- a controller coupled to the sensor and the drive assembly;
- wherein the controller receives the output signal and controls the drive assembly according to the output signal.
4 more elements
A mower comprising:
- a first upper arm;
- a second upper arm;
- a cross member extending transversely between the first upper arm and the second upper arm;
- a first housing coupled to the cross member and the first upper arm;
- a second housing coupled to the cross member and the second upper arm;
- a grip at least partially received within the first housing and the second housing, wherein the grip is movable relative to the first and second housings;
- a biasing member biasing the grip, the biasing member at least partially positioned within the housing;
- a sensor positioned within the housing, wherein the sensor generates a control signal based on the position of the grip with respect to the cross member;
- and
- a controller that receives the control signal and operates the mower based on the control signal.
7 more elements
A mower comprising:
- a deck defining a handle pivot axis;
- a drive system;
- a handle member coupled to the deck and rotatable with respect to the deck about the handle pivot axis;
- a lower arm coupled to the handle member;
- an upper arm telescopically coupled to the lower arm;
- and
- a speed control assembly including:
- a housing coupled to the upper arm;
- a grip at least partially received within the housing and movable relative to the upper arm;
- a sensor positioned within the housing, the sensor detecting displacement of the grip relative to the upper arm and generating a control signal, and
- a controller that receives the control signal and operates the drive system based on the control signal, wherein the control signal is proportional to the magnitude of displacement of the grip relative to the upper arm.
