Abstract

A coupler to secure a work attachment to a work vehicle is disclosed. The work attachment includes a first pin and a second pin, while the coupler body has a first engagement portion which is configured to accept the first pin and a second engagement portion configured to accept the second pin. The coupler body has a guide and a slider configured to slide along the guide. The body of the slider includes a first locking portion and a second locking portion. The coupler has a trigger located on the coupler body such that the trigger is released by contact with the second pin; and a first actuator that is activated by release of the trigger. When the trigger is released the first actuator moves the slider along the guide into an engaged position where the first locking portion engages and retains the first pin in the first engagement portion of the coupler body and the second locking portion engages and retains the second pin in the second engagement portion of the coupler body at the same time.
