发明名称 Detection system for front-mounted mid-PTO driven implements
摘要 A detection system for front-mounted mid-PTO driven implements includes a sensor positioned adjacent a shaft connected between a mid-PTO driveshaft and a front mounted-implement. A controller may be electrically connected to the sensor, to a fuel pump solenoid, and to a reverse sense switch that indicates to the controller if a reverse pedal is actuated. When the controller receives a signal indicating the reverse pedal is actuated, the controller does not shut off the fuel pump solenoid if the controller also receives pulse signals from the sensor within a specified frequency range based on a desired PTO speed, but shuts off the fuel pump solenoid if the controller does not receive pulse signals from the sensor or receives pulse signals from the sensor outside the specified frequency range.

主权项 1. A detection system for front-mounted mid-PTO driven implements comprising: a sensor positioned adjacent a shaft connected between a mid-PTO driveshaft and a front mounted-implement, the sensor providing pulse signals as the shaft rotates; and a controller electrically connected to the sensor, to a fuel pump solenoid, and to a reverse sense switch that indicates to the controller if a reverse pedal is actuated, so that when the controller receives a signal indicating the reverse pedal is actuated, the controller does not shut off the fuel pump solenoid if the controller also receives pulse signals within a specified frequency range based on a desired PTO speed, but the controller shuts off the fuel pump solenoid if the controller does not receive pulse signals from the sensor or receives pulse signals from the sensor outside the specified frequency range.
