Ranked third among the major global industrial groups in the agricultural mechanization sector, with a consolidated turnover of just under 19 billion euros, Kubota has experienced exponential growth in the Italian market over the past decade. This growth has allowed the Osaka-based multinational to achieve and maintain a market share of over five percent.
Tailor-Made Solutions
This successful journey is also the result of an expansion in product range pursued by the Japanese company, with the aim of making its commercial offering as well-suited as possible to meet the operational needs of different types of agriculture practiced in Italy. Not coincidentally, this commitment was recognized last year by the national market when the “M4073” model ranked sixth among the most registered utility tractors in 2023. Contributing to this achievement were the versatility and multi-functionality of a product line built around two medium-power models, characterized by wheelbases of about 2,135 millimeters and ground masses of around 3,000 kilograms. These features allow the machines to successfully handle a variety of tasks, ranging effortlessly from farm handling to forage applications, as well as transplanting, hoeing, and crop protection spraying in horticulture.
In this context, the two models “M4063” and “M4073” have been equipped by Osaka Group’s technicians with Kubota’s Stage V compliant “V3307-Cr-Te5” series four-cylinder engines, with a displacement of three liters and 300 cubic centimeters. These engines deliver maximum power outputs of 66 and 74 horsepower, respectively, and feature an electronic governor that controls engine speed to maintain a constant RPM regardless of load. This helps optimize the quality of tasks requiring steady and calibrated forward speeds.
Top Speed at Reduced RPM
To further enhance operational precision, the models are equipped with a transmission featuring three ranges and six gears, resulting in 18 forward and 18 reverse speeds, which can be increased to 36+36 through an optional super reducer called “Dual Speed.” The transmission also includes the “OverDrive” function, which allows the tractor to reach 40 km/h on the road at a reduced engine speed, 20 percent lower than the nominal rate. The system also incorporates an electro-hydraulic reverse shuttle, operable even under load, and a parking brake system integrated into the gear lever, eliminating the need for the operator to use the traditional handbrake when stopping the tractor.
The hydraulic system, delivering 63 liters per minute, feeds up to three auxiliary distributors, and the two-speed power take-off (PTO), operating at 540 RPM in both standard and Eco versions, adds to the versatility of the machines. Additionally, a rear lift with a maximum capacity of 2,500 kilograms and a front loader, pre-installable at the factory, ensure the machines are equipped for various tasks. All of these components can be easily and immediately managed from operator stations available in either platform or cab versions. The cab version allows users to benefit from the comfort provided by “Ultra Grand Cab II” cabins, borrowed from the top-of-the-range “M7003” models, which are distinguished by superior ergonomic and volumetric standards.
Superior Comfort
In line with this goal, the large heat-insulating panels ensure full visibility of the work area, even when using the front loader. The pneumatic suspension seats and the positioning of the air conditioning system under the driver’s seat further enhance comfort. This design choice allows the air vents to be positioned in a way that creates an enveloping and balanced airflow throughout the cabin.
