Introduction
Kubota M5660SU Utility Tractor
The Kubota M5660SU is a utility tractor produced between 2015 and 2025, designed for versatile agricultural and field operations. It balances compact dimensions with mechanical robustness, adhering to modern emission standards.
Engine and Performance
The tractor is powered by the Kubota V2403-CR-TE4, a 2.4-liter, 4-cylinder turbocharged diesel engine. It delivers a net power of 56 hp (41.8 kW) at a rated 2600 RPM. The engine utilizes common rail direct injection and includes a diesel particulate filter (DPF) to comply with Tier 4 emission regulations.
Transmission and Drivetrain
The drivetrain features an 8-speed forward and reverse shuttle transmission, utilizing a hydraulic shuttle for directional changes. Power is managed through a wet disc clutch, and the tractor is available in either two-wheel drive or four-wheel drive configurations, supported by mechanical wet disc brakes and hydrostatic power steering.
Hydraulics and Hitch
The hydraulic system is an open-center design providing a pump flow of 10.6 gpm (40.1 lpm), with options for one to three valves for external implement control. The rear hitch is a Category II/I type, equipped with telescoping lower links and position control, offering a lift capacity of 3307 lbs (1500 kg) at 24 inches behind the lift point.
PTO and Operator Environment
The independent rear PTO operates at 540 and 540E RPM, engaged via an electro-hydraulic wet disc clutch for smooth power transfer. The operator station is equipped with a two-post foldable ROPS for safety, providing a balance between protection and accessibility in low-clearance environments.
Conclusion
The Kubota M5660SU is a reliable utility tractor suited for small to mid-sized farming operations and general land maintenance. Its combination of a Tier 4 compliant engine, standard hydraulic shuttle transmission, and flexible Category II/I hitch system makes it a functional choice for diverse implement-based tasks.
