Overview
The Caterpillar 955L and 951C are both robust crawler loaders designed for earthmoving, site preparation, and loading operations. While similar in function, these machines differ in power, engine design, and some features that affect their suitability for specific jobs.
Engine and Power
Operators upgrading from a 951C to a 955L often report improvements in power, control, and fuel efficiency. For applications demanding heavier loads or prolonged operation, the 955L’s enhancements provide tangible productivity gains and operator comfort.
Conclusion
While the Caterpillar 951C presents a reliable, proven crawler loader option, the 955L offers modernized features, greater power, and efficiency suited to increased labor demands. Choice between models depends on project needs, budget constraints, and maintenance preferences. Understanding these differences aids in selecting the optimal machine for construction or agricultural applications.

Engine and Power
- 955L: Equipped with the Caterpillar 3304 turbocharged engine delivering approximately 130 hp. This model offers improved fuel efficiency and power output suitable for tough, high-demand workloads.
- 951C: Typically equipped with the Caterpillar 3304 naturally aspirated engine or earlier variants, producing slightly less power than the 955L, suitable for less intensive applications.
- The 955L generally offers higher operating weight (around 30,200 lbs) compared to the 951C (approximately 26,000 lbs), providing better traction and stability.
- Loader bucket capacity on the 955L can reach up to 2.1 cubic yards, potentially larger than the 951C, improving loading efficiency.
- The 955L offers higher hydraulic flow and improved control systems, facilitating precise and powerful loader operation.
- The 955L has slightly larger overall dimensions including width and height, accommodating upgraded components and operator comfort.
- Both models maintain comparably robust undercarriage systems, but the 955L may feature enhanced track rollers and suspension for a smoother ride and durability.
- The 955L often includes upgraded cab ergonomics, improved instrument panels, and better visibility.
- Control responsiveness and reliability in the 955L surpass that of the older 951C due to modernized hydraulic system controls.
- Many parts are interchangeable between the 951C and 955L models, including some engine components, buckets, and undercarriage parts.
- The 955L benefits from improved reliability through design updates, reducing maintenance frequency.
- Turbocharged Engine: An engine fitted with a turbocharger that forces more air into combustion chambers, increasing power output.
- Operating Weight: The total weight of the machine in working condition including fluids and operator.
- Hydraulic Flow: Volume of hydraulic fluid delivered, impacting the speed and force of hydraulic functions.
- Undercarriage: Track and suspension components supporting mobility and stability.
- Bucket Capacity: Volume measure of the load a loader bucket can hold.
