The Rise of Pattern Selectability in Compact Excavators
Modern compact excavators like the John Deere 35D offer a feature that was once rare in the industry: selectable control patterns. This allows operators to switch between backhoe-style controls and excavator-style controls with the flip of a lever or button. The feature emerged as manufacturers sought to make machines more versatile and accessible to operators trained on different systems.
Historically, manufacturers followed their own control logic. Caterpillar popularized the excavator pattern, while John Deere and Case leaned toward backhoe-style controls. As operators moved between machines or transitioned from loader backhoes to compact excavators, the need for pattern flexibility became clear. Today, most major brands—including Kubota, Bobcat, and Takeuchi—offer pattern change valves or electronic switches.
Terminology annotation:
The choice between backhoe and excavator mode is largely a matter of muscle memory. Operators tend to favor the pattern they first learned, and switching can feel unnatural—even frustrating—until retraining occurs. For those who spent years on loader backhoes, the backhoe pattern feels intuitive. Excavator-trained operators, especially in pipeline or demolition work, often prefer the excavator pattern.
In Missouri, a contractor who had run Deere-style controls for over a decade found himself struggling with a rental machine set to Cat pattern. After flipping the pattern switch, productivity returned instantly. The ability to adapt the machine to the operator—not the other way around—is a major advantage in mixed fleets and rental environments.
Mechanical Equivalence and Performance
There is no mechanical advantage to either control pattern. The hydraulic system, cylinder response, and breakout force remain unchanged regardless of joystick configuration. The difference lies entirely in how pilot signals are routed to the main control valve.
Performance factors:
Training and Transition Strategies
For operators transitioning between patterns, retraining is essential. Switching control modes without preparation can lead to erratic movements, reduced productivity, and even safety risks.
Training tips:
Fleet Management and Operator Versatility
For fleet managers, pattern selectability adds value. Machines can be deployed to different crews without concern for control compatibility. It also allows cross-training and improves operator retention by reducing frustration.
Management strategies:
Conclusion
The ability to switch between backhoe and excavator control modes is a subtle but powerful feature in compact excavators. It reflects the industry's shift toward operator-centric design and acknowledges the diversity of training backgrounds. While the hydraulics remain the same, the hands that guide them do not. And when those hands are given the choice, productivity follows. Whether you dig with a Deere pattern or swing with a Cat rhythm, the goal is the same—precision, efficiency, and control. The pattern is just the path. The operator makes it art.

Terminology annotation:
- Backhoe Pattern (Deere Controls): Left joystick controls boom up/down and swing; right joystick controls dipper in/out and bucket curl.
- Excavator Pattern (Cat Controls): Left joystick controls swing and boom up/down; right joystick controls dipper in/out and bucket curl.
- Pattern Change Valve: A mechanical or electronic device that reroutes hydraulic pilot signals to change joystick behavior.
- Pilot Controls: Hydraulic or electronic joysticks that send low-pressure signals to main control valves.

Mechanical Equivalence and Performance
There is no mechanical advantage to either control pattern. The hydraulic system, cylinder response, and breakout force remain unchanged regardless of joystick configuration. The difference lies entirely in how pilot signals are routed to the main control valve.
Performance factors:
- No change in cycle times between patterns
- No impact on fuel consumption or hydraulic efficiency
- No difference in digging geometry or reach
- Operator comfort and control precision may vary based on familiarity
- Choose the pattern that matches your dominant operating experience
- Train new operators on both patterns to improve flexibility
- Label machines clearly to indicate current control mode
- Use pattern change as a troubleshooting step if controls feel reversed
Training and Transition Strategies
For operators transitioning between patterns, retraining is essential. Switching control modes without preparation can lead to erratic movements, reduced productivity, and even safety risks.
Training tips:
- Practice in open areas with no obstructions
- Start with slow movements and deliberate control inputs
- Use cones or markers to simulate trenching or grading tasks
- Alternate between patterns during training sessions
- Record progress and comfort level over time
Fleet Management and Operator Versatility
For fleet managers, pattern selectability adds value. Machines can be deployed to different crews without concern for control compatibility. It also allows cross-training and improves operator retention by reducing frustration.
Management strategies:
- Maintain a control pattern log for each machine
- Include pattern preference in operator profiles
- Use pattern change as a tool for skill development
- Encourage dual-pattern proficiency for long-term operators
