John Deere has announced several new models of tractors for its new 2012 line of farm equipment. While the agricultural giant has kept some of the traditional features found in the 8440 Tractor, there have been key additions to its 9560R Tractor to meet the growing demands of the industry.

The John Deere 8440 Tractor was part of the Iron Horses Series that was manufactured from 1979 to 1982. Built in the original Waterloo, Iowa factory, the machine was a smaller version of the 8640 model, according to Tractor Data.

Featuring a six-cylinder diesel engine that could produce 215 horsepower and a claimed PTO rate of 179.83 horsepower, the 8440 was a smaller tractor from the agricultural giant that packed a lot of punch.

Along with the potential for raw power, the engine was four-wheel-drive and featured extensive take-off ability from the rear of the vehicle. The 1,000 rear RPMs that were featured helped to give the model a rear life capability of 8,545 pounds, Tractor Data reported.

The machine had a wheelbase of 125 inches and weighed more than 21,600 pounds, and had a fuel capacity of 156 gallons. The hydraulics system could hold 35 gallons and had two flow valves.

John Deere combined the raw power of its past models with the new technology that it has been designing in the new 9560R Tractor.

A completely redesigned hydraulics system can be found in the new model, along with selective control valves that allow for greater potential for GPM.

Compared with the 215 horsepower that the older model offered, the 9560R Tractor comes with 560 horsepower and a claimed 319 PTO horsepower. The increased power is supported by a redrawn cab design, that offers more comfort and visibility for the driver, reported Ag-Power Inc.

The newer model also comes with an abundance of comfort-based improvements that will allow for easier operation and maintenance, which include Field Cruise capabilities, an iTEC (Intelligent Total Equipment Control) system and adjustable flood lights for night operation.

An AM/FM radio, convenient storage space, battery boost terminal and a heater and air conditioner are also improvements that John Deere has made on the previous models of tractors.
