Allis Chalmers 185
The Allis Chalmers 185 is a row crop tractor that was made from 1970 to 1981. It has a 2WD drive system and a 4x2 chassis, which means it has two big wheels in the back and two smaller wheels in the front. This tractor is good for working in fields with crops planted in rows. Under the hood, the Allis Chalmers 185 has a 6-cylinder diesel engine that is liquid-cooled. The engine size is average compared to other tractors. It can run at 2,200 rpm, which is above average speed. The tractor weighs 6,710 pounds, which is on the lighter side for tractors. It has a three-point hitch in the back, which lets it connect to different farm tools. The tractor also has two PTO speeds, 540 rpm and 1,000 rpm, for powering attachments. Farmers can choose to add a roll-over protection system (ROPS) and canopy for safety.
