Features and benefits
Increased horsepower
You will appreciate the low operating noise, easy serviceability of emissions components and increased horsepower (+7 hp) of the high-performance engine that is EPA Tier 4 Final emissions certified.
Engineered for long life
Your excavator is designed to be part of your fleet for a long time with its sturdy undercarriage, robust under guards and the use of thick, high-tensile-strength steel plates throughout the boom and arm structures.
Quick cycle times
For your heavy-duty projects, the dual swing motors and arm quick return circuit provide fast cycle times under heavy loads.
Easy to move
You will enjoy how easy it is to transport the PC650LC-11 between job sites and the less disassembly required to meet transportation weight requirements. Plus, you don't need to rent a crane to remove the counterweight during movement, which can help lower your transportation costs.
Simplified maintenance
Ease of serviceability with latched service access doors and grouped service points. Designed to save time and money on repairs, Tier 4 Final emission system diagnostics monitor up to 167 vehicle parameters and notifies you when and where maintenance is required.
Cost-saving hydraulic efficiency
You will appreciate this machine's increased hydraulic efficiency and reduced fuel consumption with its larger bucket return piping size that reduces hydraulic back pressure in the bucket circuit in order to match the machine load to hydraulic pump output.
