THE AGRO 6-liter tractor from Deutz-Fahr cuts a narrow path. The four-axle prototype is only 6½ ft. (2 meters) wide so it can be driven down European roads. The new tractor is Deutz-Fahr's largest with 600 hp. A Deutz engine with 8 cylinders and 60-liter capacity powers the mammoth machine. The tractor will handle many types of equipment — from fertilizer and seed tanks to large sprayers and tillage equipment.
