Landini crawler tractors accounted for approximately 30 percent of total sector registrations in 2025. A performance driven by the same qualities of reliability and durability that have enabled the company to extend the maintenance intervals of its Trekker4 models to every 1,000 operating hours
Crawler traction is an old technology, yet it continues to prove remarkably relevant whenever working conditions become particularly demanding, slopes become extremely steep, or maneuvering space is severely limited. In such situations, only crawler tracks make it possible to continue working. Their track shoes literally grip the ground, the tracks can operate independently to allow the tractor to pivot on the spot, and their low center of gravity delivers levels of stability beyond those normally offered by conventional wheeled tractors. At the same time, crawler tracks distribute the machine’s weight over a much larger contact area than tires, significantly reducing ground pressure.
These advantages have been confirmed by more than a century of history and remain particularly valuable in vineyards, orchards, and mountainous regions, where crawler tractors continue to be the preferred choice for operators working in conditions that would otherwise be impossible.
Naturally, every solution has its drawbacks. Tracks and asphalt have never been ideal companions, operator comfort has traditionally been open to discussion, and maintenance requirements have generally been frequent. However, Landini has minimized these limitations in its Trekker4 and Trekker3 Compact crawler ranges by adopting the latest engineering solutions.
Among the most significant developments is the option, on selected models, to replace conventional steel tracks with rubber tracks developed by leading tire manufacturers. Equipped in this way, the machines retain all their traction capability and low ground impact while offering comfort levels comparable to those of conventional wheeled tractors. They also require less maintenance and can travel on public roads without the need to fit special road pads.
The rubber-track versions of the Trekker range represent the latest evolution of a machine category that Landini has always designed around reliability and robustness, bringing traction, stability, and productivity to the environments where terrain makes life difficult for other machines.
Trekker4: A Proven Performer
The Landini Trekker4 crawler range is available in specialist F versions and open-field M models. The two families differ not only in their dimensions but also in their overall construction.
The F models weigh 3.9 tonnes, offer a minimum width of 1.41 meters, and can be equipped with 310 mm or 360 mm steel tracks.
The M versions weigh 4.5 tonnes, have minimum widths starting from 1.70 meters, and are available with either steel or rubber tracks measuring 400 or 450 mm in width.
The M models can also be fitted with cast-iron ballast integrated into the track frames, lowering the center of gravity without compromising functionality. When working on particularly demanding slopes, having additional weight positioned exactly where it is needed makes a substantial difference without placing excessive demands on the engines.
Power comes from Deutz four-cylinder engines with a displacement of 2.9 liters, delivering between 75 and 112 horsepower depending on the model, with maximum torque ranging from 375 to 420 Nm. These performance characteristics remain virtually constant across a broad operating range, ensuring consistent traction without requiring frequent gear changes.
To further simplify operation, the tractors feature the Engine Memo Switch, which stores and recalls the optimum engine speed for each task at the push of a button. It is one of those functions that initially appears minor but proves invaluable in the field by allowing operators to focus entirely on the job at hand.
The hydraulic system also contributes significantly to productivity. As standard, it consists of two pumps delivering 28 and 42 liters per minute. For applications involving particularly demanding implements, this can be upgraded to a three-pump system delivering 56 and 28 liters per minute to the hydraulic valves and rear hitch, plus an additional dedicated 28-liter-per-minute pump supplying the steering, brakes, and transmission.
The resulting total hydraulic flow of 84 liters per minute can be managed through up to five rear remote valves, each operated by its own dedicated control lever.
A servo-assisted two-speed PTO offering either 540/540E rpm or 540/1,000 rpm, together with the 16+8 Speed Four synchronized mechanical transmission with shuttle reverser, completes the technical package.
The tractors’ ability to work continuously and reliably is supported by maintenance intervals extended to every 1,000 operating hours, compared with the 600-hour intervals that remain the industry standard.
To help operators take full advantage of these long service intervals, Landini has also paid particular attention to comfort. The operator platform is isolated by four Hydro Silent-Blocks, while the driving position adopts an automotive-style layout with clutch and brake pedals combined with an air-suspended Grammer seat.
These features clearly demonstrate that the engineers who designed the Trekker4 understood that someone would spend long hours behind the controls and deserved to return home at the end of the day without back pain.
Comfort and protection can be enhanced further by specifying the optional six-post cab with generous all-round visibility. It incorporates climate control and a pressurization system equipped with activated carbon filters, enabling Category 4 certification.
During crop protection treatments, this equipment contributes not only to operator comfort but, more importantly, to health and safety.
The rear hitch is equally impressive, with lifting capacity increasing from the standard 3,150 kg to an optional 4,500 kg—the highest capacity in its segment.
Quick couplers simplify implement attachment, while the Ergonomic Lift System (ELS) raises and lowers implements at the push of a button, allowing faster headland turns, higher productivity, and reduced operator fatigue.
Trekker3: Compact with Character
The Trekker3 Compact family currently consists of a single model specifically developed for operation in high-density orchards and vineyards.
Its minimum overall width of just 1.15 meters allows access even to the narrowest rows while maintaining the lateral stability essential for safe operation.
Operator health and comfort are enhanced by the four Hydro Silent-Blocks supporting the operator platform. While they obviously cannot transform an open crawler tractor into a luxury sedan, they significantly reduce vibration and noise.
Driving comfort is further enhanced by the flexibility of the Rehlko KDI 2504 four-cylinder engine. This 2.5-liter unit develops 75 horsepower, with performance curves designed to prioritize consistent power delivery rather than peak output—exactly what is required for operators spending long hours working at constant engine speeds without interruption.
The engine is paired with Argo Tractors’ in-house developed Speed Four synchronized mechanical transmission with Hi-Lo range. When equipped with the creeper gearbox, it offers a total of 16 forward and 8 reverse gears.
It also powers a dual-pump hydraulic system delivering 22 and 43 liters per minute, with the 43-liter circuit dedicated to implement operation, providing sufficient hydraulic capacity for virtually every implement used in specialist farming applications.
The result is a compact crawler tractor that performs exactly as intended while maintaining low operating costs. It is a machine that works without compromise—a tractor that goes where others cannot, pulls where others fail, and operates safely on slopes that force even conventional specialist tractors to give up.
Landini crawler tractors: always connected
Even machines designed to tackle the toughest terrain must now be capable of communicating with the farm in real time. Connectivity improves productivity, reduces fuel consumption, and enhances operational safety.
For this reason, Landini has equipped the Trekker range with telemetry, remote diagnostics, fleet management software, and interoperability with the Agrirouter platform.
Using the Landini Farm and My Landini mobile apps, operators can monitor the operating parameters of multiple machines, optimize field efficiency, and manage prescription maps directly from a smartphone.
These are practical tools rather than marketing features, designed for customers managing multiple machines and intended to prevent the inability to diagnose a problem remotely from turning into costly downtime during the busiest periods of the agricultural season.
