Yanmar AF-22 Compact Utility Tractor
The Yanmar AF-22 is a compact utility tractor produced between 1992 and 1997 as part of the AF-24 series. Designed for versatility in agricultural and land management applications, this machine combines a liquid-cooled diesel powertrain with a compact chassis to provide maneuverability in confined spaces.

The tractor is powered by the Yanmar 3TNS82 engine, a 1.4-liter, 3-cylinder diesel unit. It produces 21.7 horsepower (16.2 kW) at a rated speed of 2500 RPM. The engine features a 82 x 90 mm bore/stroke configuration. The transmission system offers two main configurations: a 16-speed shuttle shift or a 16-speed four-speed power shift, both equipped with a creeper range to facilitate precise speed control during specialized operations.
Mechanical Specifications and Handling

The machine has a wheelbase of 153 cm, a total length of 287 cm, and a ground clearance of 31 cm, contributing to its stability and ability to navigate rougher ground.
