Kubota Commercial Mowers
F3990 Commercial Diesel Front Mower
The new standard in professional front-mount mowers: Kubota’s flagship F3990 features a liquid-cooled, 39HP Kubota diesel engine with an electronic governor that stabilizes engine speed at 2,500rpm with the PTO switched on for enhanced cutting and discharge performance. Add the optional 100” Flex Mower Deck attachment for even more precision-cut coverage.
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.
New Digital Panel
The new easier to read LCD digital panel provides vital information about the F-Series mower at a glance, including DPF-related information, engine speed, remaining fuel, water temperature and hour meter.
Downtime is unproductive time, so the F-Series is designed for quick and simple maintenance. From the quick-release engine cover to the 90-degree tilt mower deck, every detail has been geared towards getting you back on the job as quickly as possible and keeping you there as long as possible.
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.
The F-Series’ high level of comfort starts with a deluxe high-back seat with four separate adjustments—weight control, lumbar support, back angle, and arm rests—to provide every operator with a custom fit and optimum comfort.

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