ENGINE DETAIL

The Fendt 939 Vario is powered by a robust Deutz TCD 7.8 diesel engine, offering impressive rated power at 360hp and a maximum power output reaching up to 396hp, which enables efficient operation in demanding agricultural tasks. With a high torque of 1141 lb-ft available at a relatively low 1450 RPM, this tractor excels in heavy pulling applications, making it ideal for plowing and tillage. However, the adherence to Tier IV Interim emissions standards necessitates careful consideration of operating conditions to ensure compliance and manage potential operational costs related to emissions control technologies.

FENDT 939 VARIO ENGINE

The Fendt 939 Vario is powered by a Deutz 7.8L 6-cylinder diesel engine, known for its high torque and efficient fuel consumption, making it ideal for heavy-duty agricultural tasks. With a substantial fuel tank capacity of 158.5 gallons, it offers extended operation durations, reducing downtime for refueling during intensive fieldwork. However, the 15.9-gallon DEF tank requires regular monitoring to ensure compliance with emissions standards, especially in environments where Tier 4 emissions regulations are enforced.

TRANSMISSION

The Fendt 939 Vario is equipped with a Vario ML260 continuously-variable transmission (CVT), allowing for seamless power delivery and optimal fuel efficiency across all operating conditions. The infinite forward and reverse gears enhance maneuverability, making it particularly advantageous in applications such as large-scale farming and specialized tasks where precision control is critical. However, the complexity of CVT systems may lead to higher maintenance demands and potential repair costs over the tractor's lifespan.

FENDT 939 VARIO TIRES

The Fendt 939 Vario features standard AG tires (600/70R34 front and 710/75R42 rear), which provide a balanced compromise between stability and traction on various terrains. Optional tire configurations, such as 800/70R38 or 900/60R42, can enhance soil compaction management and traction performance, beneficial for operations on soft terrains or when towing heavy loads. However, larger tires may also lead to increased fuel consumption and potential fitment issues on narrow paths.

Standard tires (ag) Front: 600/70R34. Rear: 710/75R42
Optional tires (ag) Front: 600/65R34. Rear: 800/70R38 Front: 710/60R34. Rear: 900/60R42
