A hydraulic control system for a swiveling construction machine includes at least one hydraulic travel motor, a first hydraulic actuation device, a second hydraulic actuation device and a hydraulic diverter valve assembly. The at least one hydraulic travel motor is configured to move the swiveling construction machine in a first travel speed and a second travel speed based on a variable pilot pressure signal. The first hydraulic actuation device is configured to actuate a first function of an implement. The second hydraulic actuation device is configured to actuate a second function of an implement. The hydraulic diverter valve assembly is configured to divert hydraulic power between the first hydraulic actuation device and the second hydraulic actuation device while maintaining operation of the at least one hydraulic travel motor in one of the first and the second speeds.

A compact excavator includes a base frame, an upper frame and first and second track assemblies supporting the base frame. The compact excavator also includes a primary implement assembly coupled to the upper frame and a secondary implement assembly. The secondary implement assembly includes a lift arm assembly pivotally coupled to the base frame and an implement coupler pivotally coupled to the lift arm assembly. The implement coupler is configured to latch an implement to the lift arm assembly.
