Hydraulic excavators generally pair motor electrical power to (usually) three hydraulic pumps rather then to mechanical drivetrains. The 2 main pumps provide oil at superior pressure (approximately 5000 psi, 345 bar) for your arms, swing motor, track motors and accessories whilst the 3rd is often a lessen pressure (≈700 psi, 48 bar) pump for pilot control of the spool valves; this third circuit allows for diminished Actual physical work when working the controls.

Digging Buckets: Ideal for earth excavation and come in different sizes for different excavator types.
