Smooth control, powerful performance
The efficient conversion of engine power into hydraulic muscle lies behind the efficiency of New Holland mini-excavators. All
models have three separate pumps to deliver optimised performance when travelling between sites or using the dozer blade, when
working with the excavator and when driving hydraulic attachments. For demanding auxiliary attachments, a fourth pump option
is available for the E57C and E60C.
To ensure smooth operation, valves control the flow of oil as the rams are fully extended and retracted, automatically providing
a cushion effect to smooth the operation of all key functions. In work this reduces shock loads transferred to the machine and
operator, reducing fatigue. This feature is further enhanced by the inclusion of an accumulator within the hydraulic circuit.
To further boost performance, the top two models have hydraulic flow summation. This advanced system delivers the enhanced
proportional control typically restricted to high capacity excavators exceeding 20t capacity.

• Oil leak compensation
• Vibration damping
• Emergency hydraulic function
Separate oil pumps deliver:
• Cooler running
• Greater efficiency
• Faster hydraulic response
• Dedicated flow to meet demand
• Fourth pump option E57C and E60
