High Performance
Get more jobs done in less time with Kubota's powerful and clean diesel engines and high lifting capacity.
Kubota Diesel Engines
Kubota diesel engines provide faster, more efficient job performance with ample power. Their high torque rise ensures quick, smooth recovery under sudden load changes, allowing seamless passage through tall or wet grass. These engines are also environmentally and economically friendly, featuring enhanced combustion efficiency, low vibration and noise levels, and reduced fuel costs.
- F2890: 28 HP / 3000 RPM
- F3690: 36 HP / 3000 RPM
High Lifting Capacity
A high lifting capacity equips the F-Series with the versatility to handle various implements, including grass catchers.
Large Capacity Fuel Tank
The substantial 61-litre fuel tank ensures longer working periods between refueling stops, reducing downtime for long jobs. The refueling pipe is conveniently located behind the ROPS (Roll Over Protective Structure).
4WD and Auto-Assist 4WD
Auto-Assist 4WD operates in both forward and reverse, automatically managing drive loads on wheels during turns. This system enhances turning efficiency and ease, minimizing wear on the turf. Full-time 4WD can also be engaged.
Hydrostatic Power Steering
Hydrostatic power steering reduces operator fatigue and simplifies maneuvering around trees and other obstacles.
Single HST Pedal
The powerful hydrostatic transmission offers quick response and excellent working speed, providing robust power for demanding mowing tasks. The single pedal design allows for easy directional changes and speed control (4WD: 20 km/h max. forward, 11 km/h reverse), freeing up hands for steering and implement control, thus increasing productivity.
Large Tyres with Wide Tread
Four large-sized tires with a wide tread pattern enhance stability and maneuverability on slopes, provide better flotation, and reduce ground compaction.
Tilt Steering Wheel
The tilt steering wheel is adjustable to multiple positions, ensuring optimal operator comfort and ease of driving.
High/Low Lever
A standard High/Low lever on all models allows for easy adjustment of mower speed to suit different terrains and situations.
Professional Mower Deck
A durable, hard-working deck designed for a wide range of mowing jobs.
Pro-Commercial Mower Deck
The Pro-Commercial mower deck features an inner baffle to prevent cut grass from discharging forward. A larger discharge chute improves overall discharge performance.

PTO Shaft Drive
Shaft drive eliminates belts and pulleys, ensuring smooth, direct power transfer from the engine to the deck and other PTO-driven attachments. This system requires less maintenance and offers greater dependability.
Multi-V-belt/Steel Pulleys
Heavy-duty cast-iron pulleys and a multi-V-belt drive system provide superior wear resistance, efficiently distribute and reduce tension, and prevent slippage during power transmission to the mower blades. This design minimizes the risk of damage and maximizes performance and power.
Swivel Anti-Scalp Wheels
Two large front wheels on the mower deck swivel independently through 360 degrees. These anti-scalp wheels keep the deck elevated above the turf, preventing unsightly damage.
Fabricated Deck with Sturdy Steel Construction
Unlike conventional pressed steel decks, the F-Series' fabricated steel decks are stronger and more durable, designed for years of reliable cutting performance with minimal maintenance.
6.0" Deep Mower Deck
The 6.0-inch deep deck design efficiently handles tall grass by allowing it to stand upright for cutting, resulting in faster mowing and a cleaner appearance.
Rear Discharge Mower
An optional rear discharge mower deck is available for applications where side discharge is not suitable. Offered in 60" and 72" sizes, these decks tilt up 90 degrees for easier cleaning and blade sharpening. They feature sturdy steel construction for durability and front lift arms positioned over the center of gravity for better control. Mulching kits are also available.
Mulching Kit (Option)
The optional professional mulching kit transforms the standard deck into a high-precision mulching unit, producing a finer mulch that is returned directly to the turf.
Simple Maintenance
Designed from the ground up for fast, easy maintenance.
Easy Maintenance
To minimize unproductive downtime, the F-Series is engineered for quick and simple maintenance. Features like the quick-release engine cover and the 90-degree tilt mower deck are designed to get operators back to work swiftly and keep them productive.
90-Degree Tilt Mower Deck
The mower deck lifts a full 90 degrees, providing unobstructed access to the blades and deck underside for simplified cleaning and maintenance.
Dual-Element Air Cleaner
This dual-element air cleaner helps maintain smooth and efficient engine operation. Only the outer filter requires replacement, while the inner filter can be cleaned with compressed air, contributing to reduced maintenance costs.
Integrated Radiator Screen
The easily cleanable radiator screen is integrated into the engine cover to ensure efficient engine cooling. A water temperature gauge and overheating alarm are also included to help prevent overheating.
New Digital Panel
The new, user-friendly LCD and LED digital panel provides vital information at a glance, including engine speed, remaining fuel level, water temperature, and hour meter.
Tool Box
Conveniently located under the seat, the tool box offers quick access storage for tools. It also serves as an ideal place to keep the operator manual for easy reference during operation.
Driving Comfort
The all-important key to safe, efficient, productive mower operation.
Comfort
Extended work hours can impact operator efficiency. Kubota F-Series mowers are equipped with a spacious operator platform and various features designed to ensure operator comfort and productivity in all working conditions, making a noticeable difference during long days.
Deluxe Seat
The F-Series offers a high level of comfort, starting with a deluxe high-back seat featuring four independent adjustments: weight control, lumbar support, back angle, and arm rests. This allows for a custom fit and optimum comfort for every operator. An optional air seat is also available.
Operator Levers
For enhanced ease of operation and convenience, the High/Low speed lever and deck-lifting lever are positioned next to the operator's seat. The lever guides are designed for quick, at-a-glance identification.
