MFWD - ILS:

Advanced engineering in the John Deere 8R Series makes it easy to transport heavy loads while using less fuel. The Independent Link Suspension (ILS) with mechanical front wheel drive (MFWD) allows you to put more power to the ground – both in the fi eld and on the road.
Fuel efficiency is enhanced, as well. With 42 km/h AutoPowr transmission, the engine runs at only 1434 rpm. With 50 km/h AutoPowr transmission, only 1713 rpm are needed.

iTEC Pro productivity:

John Deere’s iTEC Pro system (intelligent Total Equipment Control) enables tractor operators to work faster and longer without tiring. As a result, owners benefit from comprehensive, highly automated operations for consistent quality of work, improved performance and the highest operator comfort.
The amount of work, time and costs savings are up to you:

1 - AutoTrac hands-free guidance reduces overlap by up to 90%.

2 - iTEC automates all machinery steps needed to accurately complete headland manoeuvres and is easily programmed or recorded via the CommandCenter display.

3 - iTEC Pro combines the functionality of both AutoTrac and iTEC to minimise overlap, cut input costs and help you work faster (available with GreenStar 2630 Display).

More hectares in less time.
All you need to do is define the accuracy of the correction signal you want to use with your StarFire 3000 or iTEC receiver to implement:

± 30 cm pass-to-pass accuracy with the FREE SF1 signal, perfect for tillage

± 10 cm pass-to-pass accuracy with the SF2 signal, ideal for fertiliser spreading and mowing.

± 2 cm repeatable RTK signal accuracy for the highest precision demands like seeding.
