With widths ranging from 155 to 180 centimeters and weighing around 4,000 kilograms, the new John Deere “5ML” series tractors are specifically designed for activities in wide orchards or vineyards, as well as for operations involving high-value crops in general. However, this is not their only mission profile. These machines offer maximum power outputs between 110 and 135 horsepower, allowing them to handle farm maintenance tasks and light fieldwork, especially forage-related activities.
Not just specialized tractors, but highly versatile machines that, thanks to their technological features, can handle a variety of tasks. Contributing to this versatility are the powertrains based on “Power Tech 4045 Pws” engines, “PowrQuad” or “Powr8” transmissions, and hydraulic systems capable of delivering up to 117 liters of oil per minute, managed by a pressure and flow-compensated “Pfc” system with load sensing. The engines are four-cylinder, Stage V compliant, with a displacement of 4.5 liters, featuring 106 mm bore and 127 mm stroke.ù
These engines breathe through four valves per cylinder, are turbocharged with a fixed-geometry compressor, and have common rail fuel injection systems operating at 2,000 bar pressure. Emission control features include a cooled EGR system at the intake and an SCR system with DOC and DPF filters for post-treatment. These modern units excel in reliability and flexibility, with a 30% torque reserve highlighting their flexibility. The engines can be paired with 16+16 or optional 32+16 transmissions. The latter not only offers more gears and enables road speeds of 40 km/h but also includes an automation feature that selects the corresponding powershift gear during range changes.
This feature, combined with the ability to change ranges, gears, and travel direction without using the clutch pedal, enhances the work comfort offered by the cabins. The cabins’ details are covered in a dedicated box elsewhere in this publication, allowing this space to focus on the hydraulic system, designed to operate substantial equipment.
The 117 liters per minute flow can supply up to eight distributors—four rear, three mid-mount, and one front. An optional additional hydraulic circuit called “Power Beyond” is available, powered by a variable displacement pump that provides extra hydraulic power to the standard circuit. This load-sensing system adjusts hydraulic power based on the variable loads the tractor encounters during work, resulting in greater work efficiency and significant savings in fuel, time, money, and component wear.
The basic system also powers the rear hitch, with a lifting capacity of about 4,900 kilograms, and an optional front hitch with a capacity of 2,900 kilograms, featuring a PTO operating at 2,000 engine RPM. This complements the standard rear PTO, which operates at 540, 750, and 1,000 RPM. Both PTO groups are electro-hydraulically operated, as are the engagement of four-wheel drive and the rear differential lock.
360-Degree Visibility
The cabins of the John Deere “5ML” series tractors are designed to ensure maximum visibility on all sides of the machine. This is achieved through a four-post frame, which also includes full-length doors for easy access and exit. Considering potential use in low-light environments or during night hours, the lighting system has been meticulously developed, including work lights that can operate simultaneously or separately, illuminating just the right side or left side to avoid blinding nearby operators. For extended use, soundproofing has been carefully addressed, with an average noise level of 77 decibels, and ease of operation for both the machine and its attachments has been prioritized. An electronic joystick for implement control and a large dashboard display acting as the human-machine interface facilitate this.
Notably, an optional Class 4 cab is available for frequent pesticide treatments, and metal fenders ensure robustness in harsh environments. The same robustness applies to the fuel tank and the rear light protection boxes, all of which convey the overall durability of these new machines.
Trajectory Management Made Easy
To facilitate work, all “5ML” series tractors can integrate all John Deere precision farming technology packages. The “AutoTrac” linear guidance system is standard, integrated into the dashboard, eliminating the need for additional displays and avoiding extra costs. The optional “Gen 4” display allows documentation of every work phase, with data transferable to the free “John Deere Operations Center.
“From this “virtual station,” all operations can be monitored, planned, and analyzed, enabling quick and informed agronomic decisions. If the tractor is used by a contractor and operates on diverse crops, the “1-Click-Go-AutoSetup” system comes into play, allowing different activities to be configured and recalled as needed. With just one click, work group settings can be changed in seconds, adapting to the task at hand and ensuring final work documentation.
Through the “John Deere Operations Center,” the tractors can also utilize software applications from partner companies, while the “John Deere Connected Support” system allows, with explicit operator consent, optimization of worksite efficiency via real-time remote machine data examination. If an irregularity is detected, the John Deere dealer is automatically and immediately informed, allowing for intervention to prevent costly machine downtimes.
