Introduction
Challenger MT275B Utility Tractor
The Challenger MT275B is a compact utility tractor produced by Iseki in Matsuyama, Japan, between 2005 and 2008. Designed for versatility, it serves as a robust solution for a variety of agricultural and maintenance tasks.
Engine and Performance
The tractor is powered by an Iseki E3CD-VTB10 liquid-cooled, 3-cylinder turbocharged diesel engine. It delivers a gross power output of 40.1 hp (29.9 kW) and a net power of 38 hp (28.3 kW). The engine features indirect injection and a 1.5-liter displacement, supported by a dual-stage dry air cleaner and a glow plug pre-heating system for reliable starting.
Transmission and Drivetrain
Operators can select between three transmission types: a 3-range hydrostatic transmission, an 8-speed SynchroShuttle, or a 12-speed PowerShuttle. The PowerShuttle variant allows for shifting between forward and reverse without using the clutch. The machine is equipped with four-wheel drive, power steering, and a mechanical rear differential lock to ensure traction in varied field conditions.
Hydraulics and PTO
The hydraulic system utilizes an open-center design with a maximum system pressure of 2276 psi (156.9 bar). Total hydraulic flow reaches 12.7 gpm (48.1 lpm) on SynchroShuttle models. The Category I rear hitch provides a lift capacity of 2800 lbs (1270 kg) at the ends. Rear PTO operates at 540 rpm, with an optional 2000 rpm mid-PTO available for additional equipment compatibility.
Dimensions and Chassis
The MT275B features a 69.7-inch wheelbase and a ground clearance of 14.1 inches, providing stability for utility work. It is equipped with wet disc brakes for consistent stopping performance and features a two-post foldable ROPS for operator safety.
Conclusion
The Challenger MT275B is a reliable compact utility tractor well-suited for small-scale farming, landscaping, and property maintenance, offering a balance of maneuverability and operational flexibility.
