Built by Iseki and distributed by White, this machine from the 1986-1988 era is a testament to reliable engineering, perfect for small farms, property maintenance, and a variety of agricultural tasks.

Engine Powerhouse

At its heart beats a robust Isuzu 3-cylinder diesel engine. This liquid-cooled marvel displaces 71.4 ci (1.2 L) and delivers a solid 21 hp (15.7 kW) at a rated 2600 RPM. With a compression ratio of 22.5:1 and glow plugs for pre-heating, starting is always a breeze, even in colder conditions. The single-stage air cleaner ensures longevity, making this engine a dependable workhorse.

Transmission Versatility

Maneuverability is key, and the Field Boss 21 delivers with a manual transmission offering a generous 12 forward and 4 reverse gears. Coupled with a standard 4x2 2WD drive system and an optional 4x4 MFWD, you can tackle varied terrains with confidence. The mechanical expanding shoe brakes provide sure stopping power.

Hydraulic Performance

This tractor is ready for your implements! Its open center hydraulic system operates at a robust 2064 psi (142.3 bar) and provides a total flow of 5.5 gpm (20.8 lpm). Combined with the reliable Type I rear hitch, the Field Boss 21 offers excellent hydraulic capability for its class.

PTO Options

Adaptability is enhanced with versatile PTO options. The Field Boss 21 comes standard with a rear PTO, and for even greater utility, a crankshaft-driven front PTO is available. This flexibility allows you to power a wide range of attachments, boosting productivity.

Compact and Capable Dimensions

Measuring 105.5 inches (267 cm) in length and 42.9 inches (108 cm) in width, with a wheelbase of 59 inches (149 cm), the Field Boss 21 is a compact machine. Its shipping weight of 1,584 lbs (718 kg) for the 2WD model makes it relatively easy to transport, while the two-post ROPS (with optional canopy) ensures operator safety.

Conclusion

"The Field Boss 21 is more than just a tractor; it's a reliable partner for those who demand efficiency and versatility in a compact package. Its Isuzu diesel engine, flexible transmission, and capable hydraulics make it an outstanding choice for a multitude of tasks. Highly recommended!"
