PTO control system
First Claim
1. A Power Take-Off (PTO) control system configured to be mounted on a vehicle, the vehicle comprising:
- a propelling transmission system for transmitting engine output to an axle,a brake pedal for placing the propelling transmission system from a power transmitting state to a power non-transmitting state in response to an operation thereof by a predetermined operational amount or more, anda PTO transmission system for transmitting the engine output to a PTO transmission shaft through a PTO clutch,the vehicle allowing selection between an independent PTO mode in which PTO power is transmitted through the PTO transmission system regardless of whether the propelling transmission system is in the power transmitting state or in the power non-transmitting state, and an interlock PTO mode in which the PTO power is transmitted only when the propelling transmission system is in the power transmitting state,the PTO control system comprising;
a mode-switch command input device for giving an instruction on selection between the independent PTO mode and the interlock PTO mode;
a PTO setting device having an engaging position for producing an engaging command and a disengaging position for producing a disengaging command of the PTO clutch; and
a PTO control unit for controlling the PTO clutch in response to a pedal operational position of the brake pedal, a mode selected by the mode-switch command input device, and a position selected by the PTO setting device;
wherein PTO mode switch implementation processing by the mode-switch command input device from the interlock PTO mode to the independent PTO mode is suspended when the PTO transmission system is in the power transmitting state, while the PTO mode switch implementation processing by the mode-switch command input device to the independent PTO mode is permitted when the PTO transmission system is placed to the power non-transmitting state.

Abstract
A PTO control system for allowing selection between an independent PTO mode and an interlock PTO mode, comprising a mode-switch command input device 11 for giving an instruction on selection between the independent PTO mode and the interlock PTO mode, a PTO setting device 12 having an engaging position for producing an engaging command and a disengaging position for producing a disengaging command of the PTO clutch, and a PTO control unit for controlling a PTO clutch in response to a pedal operational position of a brake pedal, a mode selected by the mode-switch command input device, and a position selected by the PTO setting device. PTO mode switch implementation processing is suspended when the PTO transmission system is in a power transmittable state, while the PTO mode switch implementation processing is permitted when the PTO transmission system is in the power non-transmittable state.
