Articulated steering: maneuverability for tractors

Most tractors are usually offered with classic front-wheel steering. However, more and more tractor manufacturers are also offering models with articulated steering. But what are the advantages of this type of steering? And which tractors are offered with articulated steering? We answer these and other questions.

How does articulated steering work?

The term articulated steering refers to a form of vehicle steering that is often used on special tractors. This form of steering is characterized by the fact that the tractor consists of two parts that are connected by a joint. The change in direction is initiated as usual via the front wheels, but the joint “bends” and the rear part of the vehicle is pulled in line with the track.

What is the advantage of articulated steering?

Articulated steering is characterized by several advantages over front-wheel steering: In particular, the small turning circle and the resulting high maneuverability characterize this type of steering. It is therefore often installed in tractors with four equally sized wheels. Due to the equal-sized wheels, these tractors often have a larger turning circle with front-wheel steering than comparable standard tractors. This disadvantage can be well compensated for by articulated steering, resulting in agile tractors that still have the advantages of a tractor with four equally sized tires. The articulated steering makes it possible to change direction even when stationary, which enables precise maneuvering during front loader or rear loader work. The directional stability of the articulated steering further enhances this maneuverability, as it also makes it possible to negotiate tight bends without swinging out the rear axles.

Articulated tractors are also particularly popular with tractors for steep slopes: The top-heavy design, in combination with wheels of the same size, can achieve a climbing capacity of 50-55%. This makes the tractor ideal for use on slopes, e.g. in vineyards. In addition, the articulated tractor has a higher tractive force with a comparatively low power requirement in contrast to standard tractors, even on yielding ground when cornering.

What is the disadvantage of articulated steering?

Of course, articulated steering does not only have advantages. One clear disadvantage is stability: when the frame bends, the weight of the tractor shifts to the outside and the risk of the tractor tipping over increases. Although modern safety systems can improve stability, an experienced driver is required to maneuver the articulated steering safely, especially with high loads. Driving stability is also poorer at higher speeds than with normal axle steering. Articulated steering can also not be driven in crab steering. In addition, tractors with articulated steering are often significantly more expensive than the same model with conventional front-wheel steering.

Areas of application for articulated tractors

Even though articulated vehicles are produced less frequently today, they still have a firm place in some areas of application. Articulated loaders are particularly popular in vineyards and on steep slopes due to their high maneuverability and climbing ability. However, articulated loaders are also still popular in the municipal sector, as they can be maneuvered very easily, especially in narrow city centers. One machine class in which articulated steering is still used comparatively frequently is yard and wheel loaders, as the high maneuverability is particularly advantageous for front loader and loading work in confined spaces.

Articulated handlebars in comparison: these models are available

Whether in vineyards, row crops or for municipal purposes - articulated loaders are suitable for many applications. Thanks to their great maneuverability and all-terrain mobility, they can demonstrate their advantages particularly in confined spaces or when working on slopes.
