Introduction
Iseki ST40 Compact Utility Tractor
The Iseki ST40 is a compact utility tractor produced between 2001 and 2004 in Matsuyama, Japan. Distributed by AGCO, this machine is designed for versatile agricultural and maintenance tasks, offering a balance of power and maneuverability in a compact frame.
Engine and Performance
The tractor is powered by an Iseki E3CD 1.5-liter, 3-cylinder turbocharged diesel engine. It delivers a net power of 37.5 hp (28.0 kW) and a gross power of 40.1 hp (29.9 kW). The engine utilizes indirect injection and a liquid-cooling system, supported by an electric starter and glow plug pre-heating for reliable cold-start performance.
Transmission and Drivetrain
The ST40 offers three transmission configurations to suit operator needs: a 16-speed synchronized shuttle, a 16-speed power shuttle, or a 3-range hydrostatic transmission. All models feature four-wheel drive, power steering, and wet disc brakes for enhanced control. The drivetrain also includes a mechanical rear differential lock to improve traction in challenging terrain.
Hydraulics and PTO
The open-center hydraulic system provides a total flow of 9.6 gpm (36.3 lpm) at a pressure of 2130 psi. The rear PTO operates at 540 rpm and is independent, utilizing an electro-hydraulic wet disc clutch. An optional mid-PTO is available to power front-mounted implements, increasing the machine's utility.
Hitch and Dimensions
The rear Category I hitch features position control, with optional draft control and telescopic ends available. The rear lift capacity is rated at 2866 lbs (1300 kg) at the ends. With a wheelbase of 68.5 inches and a width of 60.2 inches, the tractor is sized for compact operation, while the two-post folding ROPS ensures safety and allows for height clearance in restricted spaces.
Conclusion
The Iseki ST40 is a robust compact utility tractor suited for professional agricultural applications, grounds maintenance, and small-scale farming. Its combination of multiple transmission options, hydraulic capacity, and compact dimensions makes it a versatile choice for operators requiring a reliable, multi-purpose machine.
