Full Throttle Is Often the Right Answer
For most operating scenarios, the Caterpillar 953 track loader performs best at full throttle. This recommendation is grounded in both mechanical design and field experience. The machine’s hydraulic system, hydrostatic transmission, and engine output are all calibrated to deliver optimal performance at maximum RPM. Running at full throttle ensures responsive hydraulics, consistent oil pressure, and efficient fuel combustion—especially important when lifting, dumping, or pushing heavy loads.
Hydrostatic Transmission Demands High RPM
The 953 uses a hydrostatic transmission, which relies on hydraulic pressure to drive the tracks and control speed. Unlike gear-driven systems, hydrostatic drives require full engine RPM to maintain adequate pressure. If the throttle is reduced, the transmission may lose torque, resulting in sluggish movement or difficulty climbing grades. Operators report that direction control—forward and reverse—is smoother and more predictable when the engine is running wide open.
Hydraulic Functions Are Tied to Engine Speed
Lift arms, bucket curl, and auxiliary functions are powered by hydraulic pumps that are directly driven by the engine. Lower RPM means slower pump speed, which translates to delayed response and reduced lifting power. For tasks like loading gravel, clearing brush, or grading soil, full throttle ensures that the loader arms and bucket respond quickly and with full force.
One operator noted that when running at partial throttle, the machine struggled to lift a full bucket of wet clay. After switching to full throttle, the lift cycle completed smoothly and without hesitation.
Exceptions for Precision Work
While full throttle is ideal for most tasks, there are exceptions. When performing delicate operations—such as placing pipe bedding, working near structures, or grading with millimeter precision—lower throttle may offer better control. Some machines are equipped with a decelerator pedal, allowing the operator to temporarily reduce RPM without adjusting the hand throttle. This feature is especially useful for fine grading or trenching near utilities.
However, the 1981-era 953 typically lacks a decelerator, so throttle adjustments must be made manually. Fortunately, the hydrostatic drive still allows for precise speed control even at full RPM, using the direction selector and travel lever.
Fuel Efficiency and Wear Considerations
Running at full throttle does increase fuel consumption, but the trade-off is often worth it. The machine completes tasks faster, reducing overall engine hours and minimizing idle time. Modern diesel engines are designed to operate efficiently at high RPM, and prolonged low-speed operation can lead to carbon buildup or incomplete combustion.
To balance fuel economy and performance:

• Use full throttle for digging, lifting, and pushing
  
• Reduce throttle slightly for travel between tasks
  
• Avoid idling for extended periods—shut down if inactive for more than 10 minutes
