The Bobcat E20 mini excavator has been a popular choice for contractors and construction workers due to its versatility and powerful performance in compact spaces. However, over time, the hydraulic system and portioning mechanisms have evolved across different generations of the machine. These changes have improved the overall efficiency, control, and reliability of the Bobcat E20. This article will take a closer look at the generations of the Bobcat E20’s hydraulic portioning, highlighting key improvements and differences over time.
Hydraulic Portioning in the Bobcat E20: Early Models
In the earlier models of the Bobcat E20, the hydraulic system was designed with a simpler configuration, but it still offered respectable performance for a mini excavator. These models had a basic hydraulic portioning system where the flow of hydraulic oil to the various components was controlled through mechanical means. While these systems worked adequately for most operations, they did lack the precise control and flexibility that modern hydraulic systems offer.
As Bobcat continued to innovate, the E20 began to evolve with the introduction of electronic control systems in the hydraulic portioning. The move to more advanced hydraulic portioning systems started to appear in the later models of the E20, allowing for more precise control and improved fuel efficiency. Electronic controls enabled smoother operation, better load management, and reduced wear on the system due to more responsive valve operation.
The transition from mechanical to electronic control valves in the hydraulic portioning system brought about several benefits, most notably in the areas of performance and efficiency.
While the newer Bobcat E20 models excel in hydraulic performance, earlier models faced challenges with their more basic hydraulic systems. The mechanical control systems sometimes led to slower cycle times, less efficient fuel consumption, and overall less precision in operation.
The Bobcat E20 mini excavator has gone through significant changes in its hydraulic portioning system across its generations. Early models relied on mechanical control systems, while newer models have embraced electronic controls to offer more precise, efficient, and responsive hydraulic performance. These advancements have led to improved operator experience, faster cycle times, better fuel efficiency, and overall increased durability. As technology continues to advance, it's likely that future models of the Bobcat E20 will see even further improvements in hydraulic systems, continuing to enhance productivity and operational ease for contractors around the world.

- Mechanical hydraulic control valves
As Bobcat continued to innovate, the E20 began to evolve with the introduction of electronic control systems in the hydraulic portioning. The move to more advanced hydraulic portioning systems started to appear in the later models of the E20, allowing for more precise control and improved fuel efficiency. Electronic controls enabled smoother operation, better load management, and reduced wear on the system due to more responsive valve operation.
- Key Features of Newer Models:
- Electronic control valves for improved precision
- Enhanced boom and bucket control for smoother operation
- Improved power management to conserve energy
- More responsive hydraulic performance
- Electronic control valves for improved precision
The transition from mechanical to electronic control valves in the hydraulic portioning system brought about several benefits, most notably in the areas of performance and efficiency.
- Increased Hydraulic Flow Control: The newer models of the E20 allowed for better flow control to each component of the hydraulic system. This increase in precision meant that operators could perform finer movements and better manage load demands without stressing the system.
- Faster Cycle Times: With more precise control over the hydraulic system, newer models of the Bobcat E20 saw faster cycle times, which translated into increased productivity. The improved response from the hydraulic system allowed operators to complete tasks such as digging and lifting more quickly.
- Better Fuel Efficiency: The advancements in the hydraulic portioning system not only made the machine easier to control but also led to better fuel efficiency. By optimizing the flow of hydraulic oil, Bobcat was able to reduce unnecessary power consumption, making the machine more economical to operate.
- Improved Durability and Longevity: With enhanced system controls and more efficient hydraulic components, newer models of the E20 showed less wear and tear over time. This contributed to longer operational lifespans and fewer breakdowns in the field.
While the newer Bobcat E20 models excel in hydraulic performance, earlier models faced challenges with their more basic hydraulic systems. The mechanical control systems sometimes led to slower cycle times, less efficient fuel consumption, and overall less precision in operation.
- Challenges in Early Models:
- Slower reaction times in the hydraulic system
- Less precision in boom and bucket control
- Higher fuel consumption due to inefficient system operation
- More frequent wear and tear on hydraulic components
- Slower reaction times in the hydraulic system
