Twice tested: ARION 660 is fuel-efficient, comfortable, and versatile.

The ARION 660 scored highly on power and economy in the DLG Powermix test, thanks to CMATIC transmission and 205 hp. The trade journal profi judged it to be an economical and extremely well-connected all-rounder in the field, around the yard, and on the road.

The suspension.

Full suspension. Four suspension points mean that the cab is fully isolated from the chassis, preventing impacts and vibration from reaching the driver. Longitudinal and lateral struts join the suspension points and keep the cab stable when turning corners or braking. An adjustable torsion strut allows you to choose between three different suspension hardnesses. The entire suspension system is completely maintenance-free.

PROACTIV front axle suspension: CLAAS suspension kinematics in ARION 600 tractors produce outstanding drive characteristics. Widely spaced suspension cylinders and roll stabilization on bends guarantee vehicle stability and safety, while the double-acting suspension with load change compensation and 4-inch suspension travel deliver outstanding ride comfort.

CMATIC continuously variable transmission

Forget everything you thought you knew about continuously variable tractor transmissions. CMATIC from CLAAS will change your mind forever.

Our continuously variable transmission increases your efficiency. The machine operates at the optimum speed at all times, autonomously – ensuring genuinely impressive ride comfort, yet simple operation. So you can focus all your attention on the job at hand and benefit from long-lasting transmission quality.

HEXASHIFT

With HEXASHIFT, you can shift effortlessly through all six powershift speeds and the four automatic ranges using your fingertips, or you can shift automatically using the HEXACTIV power shift unit. Overlapping powershift speeds allow the full output potential of the engine to be utilized and provide smooth range shifting on the road.

Operator assistance systems and data management.

There is no substitute for experience. It's what allows you to respond quickly and appropriately to the challenges you face in your daily work. When you're dealing with difficult terrain or changing soil conditions, you have to make decisions very quickly to get the job done right.

Data has long since become an indispensable operating resource. To profit from its full potential, you should take care of your data with as much attention as you do your machinery fleet. And that includes making sure all systems, machines and processes are meaningfully connected and the data generated is sent to the appropriate place for analysis.

CEMOS drivers are unbeatable.

CEMOS is the most comprehensive operator assistance system for tractors on the market. It helps you find the optimum settings for the tractor and implement. In a benchmark test, independent test institute, DLG, confirmed that CEMOS increased the work rate (acres/hr) by up to 16.3% and decreased fuel consumption (gal/acre) by up to 16.8%.
