Purpose and Function of the Decel Pedal
On Caterpillar skid steers and compact track loaders, the decelerator pedal—often referred to as the “decel pedal”—serves as a manual override to reduce engine RPM temporarily without changing the throttle setting. This feature is particularly useful when operating in rough terrain, performing precision tasks, or transitioning between high-speed travel and low-speed control.
Unlike the main throttle, which sets the engine speed for hydraulic and drive functions, the decel pedal allows the operator to momentarily reduce RPM for smoother control. Once released, the engine returns to its preset throttle level, maintaining productivity without requiring constant throttle adjustments.
Common Use Cases and Operator Benefits
Operators report using the decel pedal in several scenarios:
Design and Integration Across Models
Caterpillar introduced the decel pedal on various skid steer models beginning in the late 1990s. On newer machines, it is typically located on the right side of the footwell, near the travel pedals. The pedal is spring-loaded and connected to the engine control module via a potentiometer or mechanical linkage, depending on the model.
Some machines also feature a hand throttle override, allowing operators to set a fixed engine speed while using the decel pedal for temporary reduction. This dual-control system is especially useful in grading and trenching applications.
Comparison with Other Brands
While Caterpillar emphasizes the decel pedal for precision control, other manufacturers like Bobcat and Case may rely more heavily on electronic throttle mapping or foot-only throttle systems. Operators transitioning between brands often note the added control offered by Caterpillar’s decel setup, especially in tasks requiring fine motor input.
Maintenance and Calibration Tips
Field Anecdotes and Operator Feedback
A contractor in North Carolina shared that he uses the decel pedal daily when crossing rough terrain with a full bucket. He noted that it prevents the machine from lurching forward and keeps the load stable. Another operator in Alberta uses the pedal during snow removal to feather blade pressure and avoid gouging pavement.
In training sessions, instructors often emphasize the decel pedal as a tool for machine finesse, encouraging new operators to practice modulation before tackling complex tasks.
Conclusion
The decelerator pedal on Caterpillar skid steers is more than a convenience—it’s a precision tool that enhances control, safety, and efficiency. Whether navigating rough ground, loading trucks, or performing delicate maneuvers, the ability to momentarily reduce engine speed without altering throttle settings gives operators a tactical edge. With proper use and maintenance, the decel pedal becomes an integral part of skilled machine operation.

Common Use Cases and Operator Benefits
Operators report using the decel pedal in several scenarios:
- Crossing uneven ground: Lowering RPM reduces bounce and improves traction, especially when carrying loads.
- Truck loading: Allows precise bucket control when placing material into tight spaces.
- Pallet handling: Reduces hydraulic surge and improves fork alignment during lift and placement.
- Tight maneuvering: Enhances control when working near structures or in confined areas.

Maintenance and Calibration Tips
- Inspect pedal linkage regularly for wear or binding
- Clean potentiometer connections to prevent erratic RPM behavior
- Calibrate pedal response during annual service to ensure smooth modulation
- Lubricate pivot points to maintain consistent feel and return spring tension
