It features a 2-wheel drive (2WD) system and a manual steering setup, making it easy to maneuver in tight spaces between rows of crops. The tractor is powered by a 4-cylinder, liquid-cooled diesel engine made by FIAT.

It has agricultural tires on both front and rear, suitable for various farm tasks. The tractor's compact size, measuring 113.5 inches long, 43.25 inches wide, and 51.125 inches tall, makes it ideal for working in orchards and vineyards where space is limited. With an operating weight of 3350 lb, it's a relatively light tractor, which helps reduce soil compaction.
