The development of hydraulics during the last 20 years or so could be first noticed by the operator in ease of operation. Discount in operator fatigue and "ease of use" has been a big driver behind many of the developments Excavator hydraulic pump methods use as we speak. The first hydraulic system to perform each better efficiency and greater ease of use was the stress compensated load-sensing (PCLS) system. This reduced operator fatigue by making the balancing act of multi-operate metering much simpler.
