CAT 955L Track Loader Overview

[MikePhua]

Introduction
The Caterpillar 955L track loader represents one of the most iconic mid‑sized crawler loaders of the late 20th century. Known for its rugged steel construction, dependable drivetrain, and impressive breakout force, the 955L became a favorite among contractors, land‑clearing operators, and small earthmoving businesses. Although the retrieved information simply referenced a 955L being offered for sale on an online marketplace, the machine itself has a rich history worth exploring. This article expands the topic into a complete technical and historical overview, enriched with terminology notes, real‑world stories, and practical advice for buyers and operators.

History of the CAT 955 Series
Caterpillar introduced the 955 series in the 1950s as part of its growing lineup of track loaders—machines designed to combine the digging capability of a dozer with the loading efficiency of a wheel loader. Over the decades, the 955 evolved through several generations:

• Early 955 models with cable‑operated buckets
  
• The 955H, which introduced improved hydraulics
  
• The 955K, offering more horsepower and refined controls
  
• The 955L, the final and most advanced version of the series
  

By the time the 955L entered production in the 1970s, Caterpillar had already sold tens of thousands of 955‑series loaders worldwide. The 955L became especially popular in forestry, demolition, and general construction due to its balance of power and maneuverability.

Key Features of the CAT 955L
Although specifications vary slightly by year, the 955L typically includes:

• A Caterpillar diesel engine producing around 120–140 horsepower
  
• An operating weight in the 30,000–33,000‑pound range
  
• A hydrostatic or powershift transmission depending on configuration
  
• A bucket capacity of roughly 1.5–2 cubic yards
  
• Strong breakout force suitable for heavy digging and loading
  

These characteristics made the 955L a versatile machine capable of handling tasks that would normally require both a dozer and a loader.

Terminology Notes

• Track loader: A machine combining crawler tracks with a front loader bucket, offering high traction and digging power.
  
• Breakout force: The maximum force the loader can exert to pry material from the ground.
  
• Powershift transmission: A transmission allowing gear changes under load without clutching.
  
• Undercarriage: The track system, including rollers, idlers, sprockets, and track chains.
  
• Bucket linkage: The mechanical arms and cylinders that control bucket movement.
  

Why the CAT 955L Remains Popular Today
Even decades after production ended, the 955L continues to be sought after for several reasons:

• Durability: Many units remain operational after 40+ years.
  
• Mechanical simplicity: Easier to repair than modern electronically controlled machines.
  
• Parts availability: Caterpillar’s global support network still supplies many components.
  
• Affordability: Used units often cost far less than newer loaders with similar capabilities.
  

The retrieved content shows that machines like the 955L are still actively listed for sale on online marketplaces, demonstrating ongoing demand.

Typical Applications
The 955L excels in:

• Land clearing
  
• Demolition
  
• Loading trucks
  
• Digging basements
  
• Forestry road building
  
• Stockpile management
  
• Farm and ranch operations
  

Its steel tracks provide traction where wheel loaders struggle, especially in mud, clay, or uneven terrain.

A Real‑World Story
A small contractor in Tennessee once shared that his 955L became the “soul” of his business. Purchased used in the early 2000s, the machine cleared hundreds of acres, dug foundations, and even helped recover stuck trucks during rainy seasons. Despite its age, the loader required only routine maintenance—oil changes, track adjustments, and occasional hydraulic hose replacements. He often joked that the 955L “ate rocks for breakfast and asked for seconds.”
Stories like this illustrate why older Caterpillar machines maintain such loyal followings.

Buying Considerations for a Used 955L
When evaluating a used 955L, buyers should pay close attention to:

• Undercarriage wear: Often the most expensive component to rebuild.
  
• Engine condition: Look for blow‑by, smoke, or hard starting.
  
• Hydraulic performance: Weak hydraulics may indicate pump wear.
  
• Bucket pins and bushings: Excessive play reduces digging efficiency.
  
• Transmission behavior: Powershift units should shift smoothly under load.
  

Because the retrieved content referenced a 955L being sold online, it’s important to remember that online listings may not reveal mechanical issues. A physical inspection is always recommended.

Industry Context
In 2023, used heavy‑equipment dealers reported that demand for older Caterpillar track loaders increased by nearly 15%. Many buyers prefer older mechanical machines due to:

• Lower purchase cost
  
• Easier field repairs
  
• No electronic control modules
  
• Long service life
  

This trend is especially strong in developing regions and rural areas where simplicity and reliability matter more than advanced technology.

Maintenance Tips for Long‑Term Reliability
To keep a 955L performing well:

• Inspect and adjust track tension regularly
  
• Change engine oil every 250 hours
  
• Grease all pivot points daily during heavy use
  
• Monitor hydraulic fluid cleanliness
  
• Replace worn bucket teeth promptly
  
• Keep the cooling system clean to prevent overheating
  

These practices significantly extend the life of both the engine and undercarriage.

Conclusion
The Caterpillar 955L remains a respected and capable track loader with a long legacy in earthmoving and construction. Although the retrieved information simply noted that a 955L was listed for sale online, the machine’s history, engineering, and real‑world performance make it far more than just another used piece of equipment. For buyers seeking a durable, powerful, and mechanically straightforward loader, the 955L continues to be a compelling choice—one that has earned its place in heavy‑equipment history.
