A control linkage for a diesel engine in a skid-steer loader is disclosed wherein the control rods for both the fuel shut-off valve and the rate of flow control valve are operably interconnected by a bracket slidably receiving the control rods. The bracket is actuatable by a single control lever in the operator's compartment to vary the rate of flow of fuel to the engine without manipulating the fuel shut-off valve and to terminate the flow of fuel by manipulating the shut-off valve after the rate of fuel flow has been reduced to a predetermined point.

An automatic locking pin retraction mechanism for a skid-steer loader is disclosed wherein the locking pins for locking the loader boom arms in an elevated position will be automatically retracted under conditions where the locking pins are extended into the path of movement of the boom arms and the boom arms are below the locking pins and moving upwardly toward engagement with the locking pins, so as to avoid engagement between the boom arms and the locking pins. The retraction mechanism includes a pivotally mounted first member engageable with one of the boom arms and a link interconnecting the first member and a mechanism for simultaneously actuating the locking pins. Pivotal movement of the first member caused by engagement with the boom arm effects a retraction of the locking pins before the boom arms can engage therewith. An over-center spring arrangement is provided to bias the first member in the engagement position or in a neutral position, depending on the position of the first member.
