Innovating by embracing the latest technologies while staying true to oneself and one’s traditions is the ultimate challenge for Landini engineers when they embark on designing a new tractor or updating existing solutions for models already on the market. Simply aligning functional features with the most cutting-edge technology in the sector isn’t enough to capture the commercial interest of those looking to invest in Landini machines.
Landini “Trekker4”
These machines must uphold, by tradition and calling, the qualities of reliability and ease of management that have allowed the Emilian brand to remain a reference point in the Italian and international tractor landscape for almost a century. Therefore, Landini tractors must blend all the necessary technical functionalities to efficiently tackle the latest agricultural practices, without introducing overly complex management solutions.
It’s a delicate balance and challenging to achieve, especially when renewing machines that have always been at the forefront of the Italian market in terms of registrations and consequently among the benchmarks in their segment. A case in point is the evolution experienced by the “Trekker4” tracked series, born in 1991 and constantly updated over the decades to enable them to best support the continuous changes in farming practices without betraying the reliability and efficiency that have made these machines one of the longest-standing and most successful traditions in the Italian agricultural mechanization landscape.
This success is closely tied to a design philosophy that prioritizes the end-user by providing them with all the main technical-functional solutions necessary to successfully tackle applications in specialist and open-field environments, the two segments traditionally referenced by the “F” and “M” versions of Landini’s “Trekker4.” Let’s be clear, optional features are available, but they are aimed at satisfying customers who require specific and often niche content, functional options that complement, without altering, the high-level standard build quality and technical richness offered.

An example of this is the engines, four-cylinder Deutz units with two liters and 900 cubic centimeters capable of delivering a range of maximum powers ranging from the 75 horsepower of the entry-level “Trekker 4-085” to the 112 horsepower of the top-performing model “Trekker 4-120.” These engines are supported by electronic controlled common-rail fuel systems, enabling compliance with stage V regulations through the combined action of SCR systems for reducing nitrogen oxides, excluding the aforementioned entry-level model “Trekker4-085,” the latest-generation EGR systems, DOC catalysts, and passive regeneration particulate filters that do not require maintenance to maintain their efficiency constant.
Landini Trekker4: also customizable
With maximum torque ranging from 375 to 420 newton-meters at 1600 rpm, with the first 250 newton-meters available already at 1000 rpm, these engines also ensure responsiveness that minimizes the use of a synchronized mechanical transmission with two ranges and four gears, supplemented by an overdrive or alternatively by a super reducer, providing 16 forward speeds and eight reverse speeds, with the latter selectable via mechanically or electro-hydraulically synchronized reversers.
Structured in this way, the Landini “Trekker4” tracked series are capable of successfully performing even in the most demanding applications conducted on rugged and irregular terrain, areas where the machines can benefit from the presence of the “Hi-Drive” hydrostatic steering system, which allows effortless management of tractor directionality through two independent clutches aimed at progressively and calibrated controlling the individual drive wheels, consequently affecting the speed of their respective track chains and therefore the machine’s directionality.
Hydraulic of 28+42 liters per minute
For equipment handling, a dual-pump hydraulic system is oriented, providing 28 liters per minute for on-board services and steering assistance, and additional 42 liters to power up to five rear distributors, engaging a two-speed power take-off, 540 rpm available as standard and eco or alternatively, at 1000 rpm, and a rear lift with a maximum capacity of 3150 kilograms, which can be increased to 4500 kilograms by integrating the assembly with two additional hydraulic cylinders.
On the other hand, the flat-formatted driver seats are oriented towards comfort and work safety, completely suspended from the chassis and the engine through hydro-silent blocks, and are equipped as standard with suspended pedals, digital dashboards displaying the main operational parameters of the tractor, and side control consoles that contribute to making the control of work groups easy and intuitive.
Similar yet not identical
The “Trekker4” series is structured based on two specific versions, namely “Frutteto” and “Montagna,” which differ from each other in terms of weight and width. The “Frutteto” models are the most compact and lightweight, with a total mass of 3900 kilograms accompanied by a minimum width of 1 meter and 41 centimeters, while the “Montagna” versions, alongside a weight of 4500 kilograms, feature a minimum width of 1 meter and 70 centimeters, aimed at ensuring greater stability on sloping terrains. Consistent with the two different mission profiles, an equal offering of specific types of track widths is provided, with semi-lubricated steel structures offering widths ranging from 310 to 360 millimeters for “Frutteto” models and from 400 to 450 millimeters for “Montagna” versions, while reinforced rubber belts are available in a unified width of 400 millimeters for both machines.
