Adjustable ground speed control devices, systems, and methods for walk-behind equipment

摘要

The present subject matter relates to adjustable ground speed control devices, systems, and methods for walk-behind equipment. A variable speed control system for a machine can include a control system base, one or more control lever selectively movable with respect to the control system base between a first operating position and a second operating position, first and second speed adjustment actuators positioned on the control system base proximal to the one or more control lever, and a control unit configured for communication with the one or more control lever, the first and second speed adjustment actuators, and a machine component. In this configuration, the one or more control lever can be configured to control the machine component to operate between a minimum operating speed and a variable maximum operating speed, where the value of the variable maximum operating speed can be adjusted by the first and second speed adjustment actuators.

1. A variable speed control system for a walk-behind working machine, the system comprising:
a control system base; one or more control lever selectively movable with respect to the control system base between a first operating position and a second operating position; first and second speed adjustment actuators positioned on the control system base proximal to the one or more control lever; and a control unit configured for communication with the one or more control lever, the first and second speed adjustment actuators, and a machine component; wherein the control unit is configured to selectively control the operation of the machine component between a minimum operating speed and a variable maximum operating speed; wherein the first speed adjustment actuator is configured to communicate with the control unit to increase a value of the variable maximum operating speed; wherein the second speed adjustment actuator is configured to communicate with the control unit to decrease the value of the variable maximum operating speed; and wherein the one or more control lever is configured to communicate with the control unit to control the machine component to operate at the minimum operating speed when the one or more control lever is in the first operating position, and wherein the one or more control lever is configured to control the machine component to operate at the variable maximum operating speed when the one or more control lever is in the second operating position.
