A coupler assembly (10) for coupling an implement to a vehicle comprises a pickup hitch (12) with an hollow inner housing (20) which is pivotal about a horizontal axis and a drawbar which is slidably received in the hollow inner housing (20). An implement coupler (16) has a coupler frame (40) adapted to be attached to the implement. A jack stand member (52, 54) is movably mounted on the coupler frame (40). A stop block (36) is mounted to the pickup hitch (12). The stop block (36) engages a first forward facing shoulder (86) of the jack stand member (52, 54) to raise the jack stand member (52, 54) from a ground engaging lowered position when the coupler frame (40) is moved towards the vehicle. The stop block (36) is spaced apart from the jack stand member (52, 54) to allow the jack stand member (52, 54) to fall to its lowered position when the coupler frame (40) is moved away from the vehicle into an uncoupled position. The jack stand member (52, 54) in its lowered position releasably supports the coupler frame (40) in a raised position above the ground. |
