Abstract

Disclosed is a coupler to secure a work attachment, having a first pin (23) and a second pin (24), to a work vehicle. The coupler includes a coupler body (2) having a first engagement portion which is configured to accept the first pin, a second engagement portion configured to accept the second pin, and a guide (see 4, figure 1). A slider (5) is configured to slide along the guide. A body of the slider includes a first locking portion (7) and a second locking portion (8). A trigger (see 15, figure 6B) is located on the coupler body such that the trigger is released by contact with the second pin. Release of the trigger activates a first actuator, such as a spring (13). 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. A method of securing a work attachment to a work vehicle using a coupler is also disclosed.
