The machine is considered all-terrain, because its cross-country ability on any type of ground, including puddles and mud, is always high. This also applies to off-road, which is especially important when working in agriculture. This is an undeniable advantage of machinery, as no similar machine has this quality (different bikes). It should be remembered that the weight of the loader is quite large. The presence of a rigid frame is provided for work in difficult conditions.
Parameters Terex 970 is much higher than the equipment of the heavy class. Not all models can dig trenches of the same depth. This figure is comparable only with those of special machines used to produce trenches in construction.
The frame of the machine repeats the U-shape and consists of a double steel frame. The welds are localized as the body is created by dies and requires virtually no stress concentrators. The coating of the supporting structure is polyurethane – anticorrosive. It guarantees preservation of the original steel quality for the entire period of operation of the equipment and prevents corrosion due to contact with water (including precipitation). The coating is done in two layers.
Only high quality and reliable materials are used for the manufacture of RI assemblies of the working bodies. The standard equipment of the loader includes the working bodies, the dimensions of which are optimal. Buying a simple assembly machine, you can get a helper, characterized by high performance and efficiency. This is a key factor when purchasing equipment.
Excellent speeds guarantee fast transport of machinery, and fuel consumption is economical.
Operator Cabin
Terex 970 operator compartment
The ergonomics of the Terex 970 excavator cab is achieved by trial and error, but so far it’s a major quality. You can adjust both the operator’s seat and the steering column. The pneumatic seats are pneumatic shock absorbers that reduce vibration and have a positive effect on the perception of the dynamic forces. A heater is provided for work in cold seasons. The operator’s viewing angle is almost 360 degrees, as all sides are glazed. The gearbox is installed automatically, which guarantees torque-free shifting.

The model is presented on the special equipment market since 2002 and is in steady demand among consumers. It is one of the leaders in its segment.
The Terex 970 Elite is the optimal combination of an excavator and a front-mounted vee with the possibility of installing an additional attachment The bucket height, serious lifting capacity and bucket capacity, as well as the considerable engine power.
The 970 elite differs from the base version (Terex 970) in a version with a board, which is sold from the center of the rear working equipment. There is a modification with a telescopic arm. The bucket with two buckets can perform seven common operations, including ground leveling. Terex produced this model for ten years from 2002 to 2012, then replaced it with a more modern one.
Design features
The Terex 970 Elites is a classic backhoe loader in 4×4 configuration with a drive and swing bucket. It works efficiently under heavy loads, which is especially appreciated by all customers. The most important advantages of the model can be called an optimal ratio of technical parameters and mechanical connections of the working equipment with adequate lifting skills. Good cross-country ability and traction allow performing almost all types of loading and unloading operations under difficult terrain conditions.
The backbone of all Terex 970 Elite components is a carrier system. Part of the BODY has a fixed structure, which is defined on a double steel U-shaped frame with local welding seams. The tractor has a balancer suspension on the front axle and a hemispherical design on the rear axle.
The body of the carrier excavator has practically no welds, as it is made by stamping method. Such a decision in the production technology had a positive impact on the rigidity and strength of the entire structure. Supporting structures have a polyurethane anticorrosive coating. It guarantees the preservation of the original quality of steel during the whole period of exploitation of the technology and prevents the appearance and development of corrosive phenomena on the metal. The coating is made in two layers. The backhoe-loader has a hydrostatic steering with an emergency manual control and a brake system with hard disc devices on the axles and three operating algorithms (two or four wheels).
One of the main features of the Terex 970 Elite excavator is the original wheelbase design. You can create not only a simple movement but also rotation of individual axes in a separate mode. Modest overall dimensions and enviable maneuvering skills in small areas allow this mobile excavator to work on replacing elements of underground technical networks and utilities with a high degree of efficiency.
Thanks to its ability to work with a large set of layering equipment, the Terex 970 Elite can also be used for a variety of special, highly specialized jobs. All work tools are controlled directly from the machine operator unit, and hydrolysis allows quick and easy device changes.
The impressive all-terrain configuration helps the tractor to overcome areas with muddy soil freely and to drive over the field, including deep toothed grooves. The special vehicle is specially designed for increased loads. As for the working elements, all the working elements and assemblies of the backhoe loader are made of high-strength steel alloy and have optimal volumetric and total parameters. Therefore, they handle difficult tasks with maximum speed and efficiency.

Moreover, this technique can be used in conditions of limited accessibility, as in closed storage, and in cramped conditions.
Work equipment installed
The standard rear excavator (backhoe) installed on the Terex 970 Elite has a capacity of 0.312 m3. The deepest excavation (with standard arm length) is 4.43 meters. With the extended arm, it reaches 5.775 meters. The maximum width of the lower cutting edge of the excavator is 0.9 m. Loading height is 4.571 meters. The loading height range when unfolded is 1.996 m.
The standard front shovel of the Terex 970 Elite backhoe is a two-blade shovel. It holds 1.2 m3 of earth (or other loose material). The maximum burial depth of the front shovel is 116 millimeters. Discharge height is 2748 millimeters. Range at maximum spreading height is 645 millimeters. Width of the lower cutting edge of the front spoon is 2387 millimeters. The outreach of the spoon is 54.5 kn.
In addition, the list of popular attachments that the Terex 970 Elite successfully works with includes a ripper; a hydraulic drill; and a hydraulic hammer.
Terex 970 Elite Engine
Under the hood of Terex 970 Elite is a 4.4L Perkins 1104D-44T liquid-cooled, four-cylinder, vertically arranged turbo diesel engine. With a maximum output of 100 hp (or 74.6 kW) at 2200 rpm, this engine produces a maximum torque of 562.7 Nm at 1400 rpm. The engine consumes 60 grams of diesel fuel per horsepower per hour. The fuel tank holds 130 liters of fuel.
What’s important is that the diesel engine belongs to the category of “tried and tested” powertrains. And these are not just words: it really is reliable, trouble-free and long-lasting in operation.
gearbox
The gearbox of this model is a four-speed automatic transmission made by Carraro. It is a fully synchronized transmission with servo control. The absorption of a particular gait is determined by an electronic matrix and depends on the value of the particular load. At the same time, the value of torque is not reduced. The main advantages of this transmission are the ease of operation and the increased capacity. This is made possible by the fact that the wheels are not blocked during gear shifting and the unit continues to move freely. The maximum forward speed of the tractor is 41.6 km/h; the maximum reverse speed is 13 km/h. Usually the first two passes are used for loading and unloading, and the rest are used for moving equipment or transporting loads.
Front-wheel drive is not permanent, but switchable; it should be used only when absolutely necessary. All gear and drive shifts can also be carried out while the tractor is in direct motion. The capabilities of the machinery can be expanded by installing additional brake circuits. This allows you to use the plate on which they are installed to stop the loader, significantly reducing the turning radius, as well as reducing accidents when working in cramped conditions. Thus, they are a kind of protection against injury to the machine operator or damage to the body.
hydraulic system
The hydraulic system of the Terex 970 Elite Backhoe Loader includes self-cleaning radiators. The coolant in this case is oil. Operation is based on the total flow of hydraulic fluid in the system. The system also includes a 160-liter-per-minute dual gear pump and load-sensitive dual gear pumps. The bypass valve pressure is 22407.9 kPa. Even in the standard version, the hydraulic cylinders are fitted with pressure relief valves to prevent sudden pressure peaks from upsetting the hydraulic system.

Terex 970 Elite Owner Reviews
Reliable reviews about the backhoe loader Terex 970 Elite in the network are few. Their overall meaning can be summed up as “good and productive equipment, but on the whole I expected more from the foreign car. It means that the build quality and the reliability indicators of the major units and assemblies are not always faultless. Some owners categorically do not like the driver’s seat installed in the cab of Terex 970 Elite. It should be noted that the backrest does not recline and armrests are not adjustable in any way. However, all owners of these units admit that the hydraulics is of high quality and durable. And if we talk about performance, the backhoe loader is quite decent.
The hydraulic system of the backhoe-loader, of course, is not as powerful as that of similar JCB or Volvo machines, but it copes with its work adequately in any difficult operating conditions. The repair of the hydraulic system takes about 8-10,000 hours. This includes selective replacement of o-rings in the rear manifold and some cylinders.
None of the owners say anything bad about the engine. You only need to “inspect” it for regular maintenance, no repairs needed at all until at least 14-15,000 hours. The Carraro transmission is the same: it has proven itself from the best side, although it causes relative discomfort with its loud gear lever. Throughout the life of a special machine with a gearbox, only basic maintenance needs to be done.
The rear axle of the machine manufactured by the same company Karraro is equipped with a wet brake. And the friction discs are replaced at about 6,000 hours.
The front axle, also made by Karraro, generally cuts well. However, the design of its pivot assemblies forces repairs over and over again. It takes about 4,000 hours to replace the pivot couplings for the first time (the steering rods must also be replaced at the same time). It takes about 8,000 to 10,000 hours to replace almost all clutches and knobs.
Costs for the Terex 970 Elite Backhoe Loader
The Terex 970 Elite backhoe loader is represented on the used construction equipment market, although not very widely due to the low popularity of this model. The price range for used units is from 1.5 million rubles (for units that were manufactured in the 2000s) to 3,500,000 rubles (for Terex 970 elite backhoe loader, which was manufactured in 2012).
