The 950B has a 3304 direct injection turbo, four-cylinder engine producing 155 flywheel horsepower (FWHP). It comes standard with powershift transmission and a sealed Z-Bar linkage.

The 950B was manufactured in the USA, with a 22Z prefix; in Japan, with a 65R prefix; and in Belgium, with a 63R prefix.

The 22Z has a rollover protection system.

The 65R and 63R are articulated vehicles with four speeds forward, four reverse, and flow amplified steering.
