What is the low throttle speed (often referred to as turtle speed) of the hydraulic excavator?

The low throttle speed, commonly known as "turtle speed," refers to the speed at which a hydraulic excavator operates while maintaining a balance between power and control for precise movements. At this speed, the excavator can perform tasks more carefully, making it ideal for operations that require accuracy such as grading, digging, or maneuvering in tight spaces.

In this context, the correct speed of 2.2 mph allows the excavator to function effectively while minimizing the risk of accidents or damage to the site or surrounding properties. This speed is engineered to provide the operator the necessary control without sacrificing the machine's capability. The other speed options do not align with the typical low throttle specifications for hydraulic excavators, which allows for a steadier approach during detailed tasks.
