Powerful and Clean
The M5660SU takes tractor performance to the next level in power even as it reduces emissions. The powerful 56 hp engine features Electronic CRS Common Rail direct fuel injection for better fuel economy. For cleaner emissions, the M5660SU is equipped with a Common Rail System (CRS) and Diesel Particulate Filter (DPF) that work together to ensure compliance with the latest EPA Tier 4 final emission regulations.

Hydraulic Shuttle
New to this class of tractor, the M5660SU’s hydraulic shuttle provides smooth, quick, and effortless shifting between forward and reverse via a single lever, eliminating the need to depress the clutch to change directions. Conveniently located next to the steering wheel, the hydraulic shuttle lever boosts productivity in any job that requires lots of forward/reverse movements, such as front loader work.

F8/R8 Transmission
A new transmission provides 8 forward and 8 reverse speeds spread across four synchronized main shift speeds and high/low speed ranges, letting you choose the right speed for the task at hand.

Ergonomical Lever Layout
All levers, including the main shift lever and hydraulic shuttle lever, are located within easy reach from a sitting position. Drivers won’t have to extend awkwardly or uncomfortably while performing tractor operations.

Live-Independent Hydraulic PTO
The M5660SU offers smooth and self-modulating hydraulic independent PTO. A PTO brake ensures smooth stops while maintaining PTO shaft speed. The shaft can be rotated 60 degrees for easy hook-up even while the engine is off.

If you're looking for an economical alternative, M5660SU models offer an optional economy PTO. This system can save you money as well as reduce operating noise. Simply select "540E” and the PTO shaft rotation speed is maintained at 540 rpm while the engine speed runs at 1828 rpm with limitation to 2132 rpm, thereby reducing both operating noise and fuel consumption.

3-Point Hitch
Rear-mounted implements can be attached quickly and easily to the Category I and II 3-point hitch, thanks to the adjustable top link, turn-buckle type lift rod, and telescopic stabilizers. The hitch provides ample lifting: up to 3307 lbs. at 24 inches behind the lift point.

SCD Type Rear Remote Valve
The M5660SU offers one rear remote valve as standard equipment and up to three as options. SCD type is self canceling detent, and FD type has a float detent.

Telescoping Lower Link
Now standard equipment on the M5660SU, Kubota’s telescopic lower link ends and adjustable lift rods ensure quick and simple attachment and adjustment of implements.

High Capacity Fuel Tank
The M5660SU now offers an ample 17.7-gallon (67 liter) capacity fuel tank to keep you working longer between fill-ups.

Bevel-Gear Front Axle
A bevel-gear front axle provides excellent maneuverability and an astonishingly tight 55-degree turning radius, letting you work efficiently in narrow spaces. Standard features include a differential lock on the rear for increased stability and traction when working under difficult ground conditions.

High-Back Bucket Suspension Seat
The M5660SU takes operator comfort to an all-new level to keep you working efficiently and with less fatigue. The high-back bucket seat features lumbar support to help you work efficiently and comfortably even when the work day is long.

New Dash Panel
A redesigned dash panel with LCD display provides you with all the information you need to work efficiently and keep your M5660SU in peak condition. The easy-to-read gauges and indicators include a fuel consumption meter, parking indicator, ECU and fault code indicators.

Constant RPM Management
The M5660SU is equipped with a constant rpm management system that maintains a constant rpm rate regardless of the terrain. When traveling across hilly terrain, simply turn the Constant RPM Management switch to "On”, and the M5660SU will maintain a constant travel speed as well as a constant PTO rpm rate when using PTO-driven implements. Constant rpm management improves work accuracy without the need to constantly adjust the travel speed and PTO shaft rpm rate.
