Earmarked for its full line of tractors will see the updated name and numbering system apply to its new 5D, 5E, 5M, and 6D series tractors.

"This new system allows customers to more quickly and easily identify the engine horsepower of a tractor, its capability, and its size by looking at the hood decal," Mr Platz said.

Each new tractor model number has six available positions.

The first position is a number and represents its size.

The second, third, and fourth positions are numbers and denote the tractor's relative metric engine horsepower according to 97/68/EC standards.

The fifth position is a letter and indicates its capability and/or price level within its family.

Deere says letters at the beginning of the alphabet will indicate a tractor has lower levels of capabilities when compared to other models in its family. More advanced specification machines will sport letters towards the middle and end of the alphabet.

Meanwhile, some tractors also will have a sixth position to designate a specific configuration such as a high-crop or narrow-profile tractor, or to show that it has tracks.

This new system does away with the word thousand in the series title.
