John Deere 8440 Specifications and Technical Data you can find on this page. The JD 8440 has a 6-cylinder diesel engine that powers it. The engine is very large and has a displacement of 7.6 liters. Engine power is directed to all 4 wheels through a gearbox that gives the tractor a total of 16 speeds when forwarding and 6 when reversing.

The total weight of the John Deere 8440 amounts to 9797 kg (21,600 lbs), which is much heavier than almost any utility tractor, but for a tow tractor, it is quite reasonable. All four tires on the tractor are exactly the same size. Each of them measures 18.4-34 (18.4 inches wide, 34 inches in rim diameter). Double wheels can be added to give the machine extra grip when working with very heavy loads. The JD 8440’s wheelbase is huge, measuring 3.17 m (125 inches). This tractor comes with a standard cab, which means it is suitable for virtually any condition.
