Introduction

Kubota L3940 Compact Utility Tractor

The Kubota L3940 is a compact utility tractor produced between 2007 and 2013. It belongs to the Kubota L40 series and is engineered for versatile agricultural and municipal applications, offering a balance of maneuverability and operational power.

Engine and Performance

The tractor is powered by a 2.0-liter, 4-cylinder liquid-cooled diesel engine. It generates a gross power output of 40.5 hp (30.2 kW) and a net power of 38.5 hp (28.7 kW). The engine is designed to operate at a rated speed of 2700 RPM, providing consistent torque for various implements.

Transmission Systems

The L3940 offers multiple transmission configurations to suit different operational requirements. The HST Plus hydrostatic transmission features a treadle foot pedal, cruise control, and the 'Stall Guard' system, which automatically manages engine RPM under load. Alternative options include the FST sync shuttle with 8 forward and reverse gears, and the Glide Shift (GST) transmission with 12 forward and 8 reverse gears.

Hydraulics and Hitch

Equipped with an open-center hydraulic system, the tractor provides a total flow of 14.7 gpm (55.6 lpm), with 9.8 gpm directed to implement functions and 4.9 gpm dedicated to power steering. The rear hitch is a Category I type, capable of lifting 3,860 lbs (1750 kg) at the ends, ensuring compatibility with a wide range of rear-mounted equipment.

Power Take-Off (PTO)

The machine features an independent rear PTO operating at 540 RPM. An optional semi-independent mid PTO is available, which operates at 2000 RPM. When the mid PTO is engaged, the rear PTO is also activated, though the rear PTO can be operated independently of the mid PTO.

Mechanical and Dimensions

Built on a 74.6-inch wheelbase, the L3940 utilizes four-wheel drive and hydrostatic power steering for precise handling. It is equipped with wet disc brakes for reliable stopping power. The tractor is available in two-post ROPS or Grand CAB configurations, with a base weight ranging from approximately 3,483 lbs to 3,968 lbs depending on the model specification.

Conclusion

The Kubota L3940 is a robust utility tractor suited for medium-duty agricultural work, grounds maintenance, and property management. Its variety of transmission choices and hydraulic capacity make it a highly adaptable platform for operators requiring a dependable machine in the 40-horsepower class.
