Kubota Diesel Engines

The F-Series diesel engines are built for greater power with cleaner emissions. The F3990’s liquid-cooled E-TVCS (vortex combustion system) engine delivers increased power and high torque for all the tractor strength you need while lowering emissions. Its combination with the Diesel Particulate Filter (DPF) Muffler further reduces emissions to make it compliant with the Tier IV Emissions regulations.

Clean emissions

The F3990 diesel engine features an electronic governor that stabilizes the engine speed at 2,500rpm with the PTO switched on for enhanced cutting and discharge performance, and increases engine speed to 2,700rpm with the PTO switched off for faster traveling speed.

High lifting capacity

A high lifting capacity gives the F-Series the versatility to handle an array of implements, including a grass catcher, snow blower, rotary sweeper, debris blower and the 100” flex mower.

Large capacity fuel tank

A large, 16.1 gallon fuel tank not only keeps you working longer between fuel stops, it also reduces the number of fueling stops needed to complete long jobs. That means more time working and less time fueling up. The refueling pipe is now conveniently located right behind the ROPS.

4WD and Auto-Assist 4WD

Auto-Assist 4WD works in forward and reverse, automatically controlling the drive loads on the wheels during turns. Auto-Assist 4WD lets you turn with greater efficiency and ease with less wear and tear on the turf. Full-time 4WD can also be engaged.

Hydrostatic power steering

Hydrostatic power steering reduces operator fatigue and makes it easier to mow around trees and other obstacles.

Single HST pedal

A powerful hydrostatic transmission provides quick response, excellent working speed, and more muscle for tough mowing jobs. The single pedal design lets you easily change the direction as well as control the speed (4WD: 12.5 mph max. forward speed, 6.8 mph in reverse), keeping your hands free for steering and implement control for increased productivity

Large tires with wide tread

Four large-sized tires provide a wide tread for greater stability and maneuverability on slopes, better flotation and less ground compaction.

Tilt steering wheel

The tilt steering wheel can be quickly adjusted to several positions for optimum operator comfort and further driving ease.

High/Low lever

The handy Hi/Low lever is standard equipped on all models so you can adjust the mower speed to better match the terrain or situation.

Pro-Commercial mower deck

The Pro-Commercial mower deck comes with an inner baffle to prevent cut grass from discharging to the front. A larger discharge chute improves discharge performance. Also need less power to run mower.

PTO shaft drive

Shaft drive means no belts or pulleys – just smooth and direct power transfer from the engine to the deck and other PTO driven attachments. Shaft drive also requires less maintenance and provides greater dependability.

Multi-V-belt/Steel pulleys

In addition to providing greater wear resistance, the heavy-duty cast-iron pulleys and a multi-V-belt drive system effectively distribute and reduce tension while transmitting power to the mower blades. The multi-V-belt won’t twist or slip, thus reducing the chance of damage to the mower. You get more performance and power – and fewer problems
