Allis Chalmers 6140

The Allis Chalmers 6140 is a utility tractor made from 1982 to 1985. It's a 2WD tractor with power steering and a synchromesh transmission that has 10 forward gears and 2 reverse gears. This tractor is powered by a Toyosha diesel engine with 3 cylinders and 40 horsepower. The engine is liquid-cooled and naturally aspirated, which means it doesn't use a turbocharger. The 6140 has a Category I three-point hitch that can lift up to 3,200 pounds, which is very high for its class. It has an independent PTO that runs at 540 rpm. The tractor weighs 4,000 pounds and measures 131.5 inches long, 68.1 inches wide, and 87.8 inches tall. It has an open operator station, but a ROPS (Roll-Over Protective Structure) and canopy were optional. The 6140 also features mechanical wet disc brakes, an open center hydraulic system, and agricultural tires on both front and rear. Some special features of the Allis Chalmers 6140 include a mechanical rear differential lock and inboard planetary final drive. It also has top-link draft sensing, which helps control the depth of implements. The tractor's engine displacement and power output are below average for its class, but its hitch capacity is very high. This makes the 6140 a good choice for farmers who need a compact tractor that can handle heavy lifting tasks.
