Terex Excavators: An Introduction
Terex was a significant player in the construction and mining equipment sector, offering a variety of machines that served the needs of contractors and heavy equipment operators. They manufactured a broad range of construction equipment, including wheel loaders, dump trucks, and most notably, excavators. The company’s excavators are known for their durability, user-friendly features, and competitive pricing.
Historically, Terex excavators were built with a focus on performance, fuel efficiency, and ease of operation. While Terex ceased to produce their own excavators after selling their construction equipment line to Volvo in 2014, the legacy of Terex excavators continues to serve industries worldwide. Many operators and businesses still rely on older Terex models for their rugged construction.
Key Features of Terex Excavators
While Terex excavators are known for their durability, like any heavy machinery, they can encounter issues over time. Operators and service technicians have identified a few common problems that may arise with these machines:
Regular maintenance is crucial to ensuring the long-term performance of your Terex excavator. Here are some essential maintenance tips to keep your machine running smoothly:
A demolition contractor who used a Terex 72-65 excavator shared his experience of how the machine stood up to years of heavy use. Despite frequent operation in challenging conditions such as tearing down buildings and lifting large debris, the excavator’s hydraulic system showed minimal issues, and the engine delivered consistent performance. The operator attributed the excavator's reliability to proper maintenance, including regular hydraulic fluid changes and regular engine cooling checks. However, the operator noted that the tracks began to show signs of wear after two years of heavy use, which was expected. The tracks were replaced, and the machine continued to perform well after the repair.
Terex Excavator Alternatives
For those considering Terex excavators but seeking alternatives, several brands provide similar machines with comparable features:
Terex excavators are a solid choice for businesses and operators seeking reliable and versatile machinery. While some older models may face hydraulic, engine, or track issues, proper maintenance and care can ensure these machines continue to perform well for many years. If you are looking for a budget-friendly option for construction, demolition, or mining, a used Terex excavator might be an excellent investment. However, always be mindful of the machine's age and condition before purchase and ensure that proper maintenance procedures are followed.
With their long-lasting durability and versatile capabilities, Terex excavators remain a valuable tool in the heavy equipment industry, even as newer models from other brands continue to hit the market.

Key Features of Terex Excavators
- Powerful Engine and Hydraulic Systems:
Terex excavators are powered by high-performance engines and hydraulic systems that allow them to perform a wide range of tasks, from digging and lifting to demolition and material handling. The hydraulic system is one of the most critical components of any excavator, as it provides the force needed to operate the boom, arm, and bucket efficiently.
- Versatility and Attachments:
Terex excavators are versatile machines, capable of handling various attachments such as buckets, hydraulic hammers, and grapples. This flexibility makes them ideal for various applications, including construction, mining, landscaping, and demolition. The ability to easily swap attachments also adds to the machine's versatility, allowing it to handle different tasks on the same project site.
- Operator Comfort and Visibility:
The operator’s cabin in Terex excavators is designed for comfort and convenience. It is equipped with ergonomic seating, advanced controls, and excellent visibility, which enhances the operator's ability to perform tasks safely and efficiently. The intuitive control systems are user-friendly, which reduces the learning curve for new operators.
- Fuel Efficiency:
One of the key selling points of Terex excavators is their fuel-efficient engines. These machines are designed to minimize fuel consumption while delivering powerful performance. For businesses looking to reduce operating costs over time, the fuel efficiency of Terex excavators provides significant long-term savings.
While Terex excavators are known for their durability, like any heavy machinery, they can encounter issues over time. Operators and service technicians have identified a few common problems that may arise with these machines:
- Hydraulic System Failures:
A common issue with older Terex excavators is hydraulic system malfunctions. Hydraulic pumps, cylinders, and hoses can wear out due to extended use or poor maintenance. These failures often result in reduced lifting power or slow operation of the boom, arm, or bucket. Regular inspections and oil changes are essential for preventing hydraulic system failures.
- Engine Overheating:
Some operators report that the engines in older Terex excavators tend to overheat, especially in high-demand situations. This can result from clogged radiators, faulty cooling fans, or issues with the engine's thermostat. Engine overheating can lead to significant damage if not addressed promptly, making it essential to regularly check the cooling system.
- Electrical Failures:
Electrical problems can occur in any piece of machinery, and Terex excavators are no exception. Issues with wiring, sensors, or the battery can cause problems with starting, operating, or controlling the excavator. It’s important to regularly inspect the electrical system to ensure proper function.
- Track Wear and Tear:
For Terex models equipped with tracks, track wear is a common issue. Tracks are designed to handle heavy loads and rough terrain, but they can wear out over time, especially in environments with sharp rocks or abrasive surfaces. Regular inspection and timely replacement of worn tracks are necessary to avoid costly downtime.
- Leaks in the Fuel or Hydraulic System:
Fuel and hydraulic leaks can occur if seals, gaskets, or hoses become worn. These leaks can be dangerous, leading to potential fires or loss of hydraulic fluid. It’s crucial to regularly inspect the system for signs of leaks and address any issues before they become major problems.
Regular maintenance is crucial to ensuring the long-term performance of your Terex excavator. Here are some essential maintenance tips to keep your machine running smoothly:
- Regular Fluid Checks:
Hydraulic fluid and engine oil are vital for the smooth operation of the excavator. Regularly check and replace these fluids according to the manufacturer’s guidelines. Clean fluid ensures the hydraulic system operates efficiently and prevents damage to internal components.
- Inspect the Tracks or Tires:
Whether your Terex excavator is wheeled or tracked, it’s essential to regularly check the condition of the tracks or tires. Look for signs of wear or damage, and replace them when necessary. Keeping the tracks in good condition ensures better traction and stability on the job site.
- Clean the Cooling System:
Overheating can lead to significant engine problems. To prevent overheating, regularly clean the cooling system, including the radiator and cooling fan. Make sure the engine coolant is at the proper level and that the system is functioning efficiently.
- Inspect and Replace Filters:
The air, fuel, and hydraulic filters should be inspected and replaced regularly. Dirty filters can lead to reduced engine performance, increased fuel consumption, and poor hydraulic efficiency. Replacing filters is an easy task that can significantly extend the life of your machine.
- Monitor the Electrical System:
Regularly inspect the wiring, connectors, and battery to ensure the electrical system is functioning correctly. Faulty electrical connections can lead to system malfunctions, so it’s important to replace any worn or damaged parts immediately.
