A lift arm cross member may connect a tilt lever support to a pair of lift arms. The lift arm cross member may have a top plate with a generally convex outer surface as the outer surface extends from a first end edge to a second end edge, and a bottom plate having first and second end edges, a first planar portion extending from the second end edge, and a curved portion extending from the first planar portion opposite the second end edge. The first end edge of the bottom plate may be connected to an inner surface of the top plate and the second end edge of the first plate may be connected to an inner surface of the bottom plate. A buffer plate may be provided within the lift arm cross member and extend between the inner surfaces of the top and bottom plates.

Lift arm cross member

A coupler for connecting an implement to a machine includes a first mounting structure configured to attach the coupler to the implement. The first mounting structure includes a first actuator including a first cylinder rod extendable relative to a first cylinder body. The first cylinder rod has a first rod longitudinal axis. The first mounting structure also includes a first wedge attached to the first cylinder rod. The first wedge is movable between a retracted position and an extended position by the first actuator. The first wedge includes a first wedge tip insertable into the implement. The first wedge tip has a first wedge longitudinal axis. The first rod longitudinal axis is offset from the first wedge longitudinal axis to form a first opening extending through the coupler adjacent the first actuator. The coupler also includes a second mounting structure configured to attach the coupler to the machine.
