¹CPM (CLAAS POWER MANAGEMENT)

The technology.

Drive ratio 1:

In the first drive ratio the tractor can start up, reverse or remain stationary in powered zero mode. (There are no mechanical shifting operations in the transmission.) The stepped planetary transmission splits the power coming from the engine (from the left) into a mechanical component and a variable, hydrostatic component. When the tractor accelerates, the rotational speeds of the two clutch shafts become closer and closer until they are the same. The drive ratio changes automatically at this point without the driver noticing.

Drive ratio 2:

In the second drive ratio the power flow and functions in the transmission change. The hydrostats switch function. The stepped planetary transmission is intelligently connected with the hydrostats by means of the clutches. As a result, the stepped planetary transmission splits the power coming from the engine (from the left), then combines it again downstream of the hydrostats.

Superior transmission control.

Powerful acceleration, smooth deceleration and a fast response to changes in load: CMATIC powertrain management shows its capabilities in all conditions and for every task. Stay relaxed and focused throughout the working day so you can concentrate on more important things – CMATIC does the rest for you.

The change in function between drive ratio 1 and drive ratio 2 guarantees consistently high efficiency at all speeds. ARION 600 / 500 CMATIC tractors are especially powerful as a result.

Efficient and user-friendly.

With engine speeds of 1,500 rpm at a top speed of 50 km/h and 1,400 rpm at 40 km/h, ARION 600 / 500 tractors also demonstrate their full capabilities in transport operations. If the accelerator is not depressed, the transmission is in powered zero mode and maintains its position reliably without creeping or rolling. This means that the tractor can start up safely and easily at steep field entrances or road junctions, even with a full load.

The benefits for you:

• Completely smooth acceleration from 0 to 50 km/h (or 40 km/h), even under maximum load
• Low fuel consumption on the road as maximum forward speed is reached at just 1,500 rpm
• Powered zero mode makes it easy to stop on slopes and start off again without using the service brake
• Drive ratio changes smoothly and automatically
• You are always in the right drive ratio
• Two drive ratios, which change the power flow and processes within the transmission – consistently high efficiency levels for low fuel consumption and maximum versatility in all applications

Engine droop at the push of a button.

The engine droop value can be used for quick and easy regulation of the engine speed under full load. The CEBIS or CIS terminal clearly displays the engine speed at which the transmission reduces the speed.

When the engine speed memory is active, e.g. for PTO work, you can specify the difference from the saved engine speed at which the transmission ratio is reduced.

Clear benefits.

• No need to use the clutch when changing range
• Good gear spacing in all ranges
• Excellent efficiency in the field and on the road for low fuel consumption
• Creep gear options down to 110 m/h
• Convenient adjustment options with CIS or CEBIS
• High operating comfort with the DRIVESTICK or CMOTION
• CLAAS powertrain management for smooth changes in range and powershift operations
• SMART STOP: stop with the brake pedal without using the clutch
• HEXACTIV auto-shift function with cruise control
• Disable cruise control and engine speed memory using the throttle pedal
• REVERSHIFT clutchless reverser with electronic parking brake
• REVERSHIFT reversing function on the ELECTROPILOT four-way control lever

HEXACTIV auto-shift function.

Because you've got more important things to do, you can leave HEXACTIV to change gear automatically. You can configure the HEXACTIV auto-shift function with a wide range of well-designed functions according to your preferences and the job in hand. Three powershift unit modes can be selected via the CEBIS or CIS.

• Fully automatic: HEXACTIV shifts for variations in engine speed depending on engine load, vehicle speed and the driver's preference/accelerator position
• PTO mode: HEXACTIV shifts so as to ensure that the engine speed/PTO speed remain as constant as possible
• Manual mode: HEXACTIV shifts according to a fixed engine speed which is programmable by the driver

With suitable pre-fittings, a front loader or front linkage can be retrofitted at any time. As an option, a robust half frame can be fitted along the engine between the front axle carrier and transmission. This frame absorbs forces as they arise and, at the same time, can be used as a coupling point for the front loader brackets. These are simply bolted to the half frame and can therefore be retrofitted at any time. If the ARION comes with a factory-fitted front linkage or a front loader, the half frame is included in the scope of delivery. Naturally, access to all maintenance points is guaranteed whatever equipment is fitted.

CLAAS tractor concept:

A long wheelbase combined with optimum weight distribution (50% front / 50% rear) and a compact overall length guarantee superb flexibility and performance.

Long wheelbase and excellent weight distribution:

• High driving comfort
• Good and safe road handling
• High tractive power and performance due to low ballast requirement
• Higher lifting capacity thanks to improved stability
• Optimises fuel consumption
• Lower ballast requirement protects the soil and guarantees dynamic road transport

Short overall length:

• Good manoeuvrability
• Short trailer combination on the road
• Good visibility
• Good guidance of front-mounted implements

Automatic PTO engagement/disengagement can be adjusted continuously based on rear linkage height. Simply move the rear linkage to the position required and press and hold the automatic PTO button. The required engagement/disengagement position is now saved.

Implement attachment is very straightforward as the PTO stub rotates freely.

PTO with the right engine speed.

A press of a button on the rear mudguard is all it takes to switch on the rear PTO and then activate the engine speed memory. Just set the right engine speed for the attached implements in CEBIS in advance. This is recommended for all operations when you routinely use the external PTO switch. It saves time and makes your job easier and safer.

The front linkage has connections for one spool valve and one free-flow return line

Hydraulics that get the job done.

• Load-sensing hydraulic system for all ARION 600 / 500 models with 110 or 150 l/min output
• In the CIS version: four mechanical spool valves on the right side console and ELECTROPILOT built into the armrest to operate two electronic spool valves
• In the CEBIS or CIS+ version: up to six electronic spool valves can be operated from the armrest – up to four of these with the ELECTROPILOT. Spool valve operation can be assigned to the F buttons on the CMOTION, multifunction armrest or ELECTROPILOT to make combined operating processes easier.
• Additionally in the CEBIS version: thanks to free assignment and prioritisation of the spool valves, every driver can configure CEBIS to suit their personal preferences and the task in hand. The frequently-used hydraulic functions are positioned side by side for smooth operation.

Hydraulic power throughout.

Power Beyond connections are provided at the rear for implements which have their own control units.

The benefits of this are:

• Hydraulic oil is supplied to the attached implement as required
• Large-diameter pipes, flat-seal hydraulic couplings and non-pressurised return flow reduce power losses

• Manual or automatic lower link stabilisers
• Wheel slip control
• Hydraulic top link
• Robust and simple top link holder
• Practical ball holder at the rear
• External controls on both mudguards for the rear linkage, PTO and electronic spool valve (depends on installed equipment)
• Wide range of hitching options such as drawbar with hitch ball, automatic clevis, pickup hitch, CUNA

Direct adjustment.

The main rear linkage functions are directly accessed via push buttons and dials on the right-hand B-pillar:

• Raise and lower
• Vibration damping on / off
• Lock rear linkage
• Activate slip control
• Lifting height limiter
• Lowering speed
• Draught and position control
• Adjustment of wheel slip control

The convex rear window and swivelling seat provide an excellent view of the implement and unimpeded operation of the rear linkage controls. The conveniently located controls enable the driver to optimise the rear linkage settings while work is in progress.

Front linkage and front PTO.

All ARION models feature a front linkage and front PTO:

• Three positions for the front lower links: folded up, fixed working position and float position in slotted hole
• Double-acting lift rams as standard
• Short distance between front axle and mounting points for improved guidance of front attachments
• 1,000 rpm PTO
• External control of the front linkage and double-acting spool valve in the CEBIS version if fitted.

With a choice of over 18 front loader models in three series, you'll be ideally equipped whatever the job.

• The large, one-piece bonnet opens at the press of a button, providing access to all the engine maintenance points
• The oil can be checked and topped up on the left-hand side of the ARION when the bonnet is closed
• All daily maintenance tasks can be carried out without tools

Long oil-change intervals (engine 500 h, transmission and hydraulics 1,500 h) save a great deal of time and money. This means that less valuable working time is lost during the season and the tractor is where it should be – at work.

Fresh air for full power.

The large intake panels in the bonnet provide plenty of fresh air for cooling and for the engine air filter. Low flow rates at the intake panels help them to stay clean and permeable at all times.The radiator assemblies are supported by a robust frame and gas-filled shock absorbers open the radiator panels to two positions for thorough cleaning. Cleaning can therefore be carried out safely and conveniently as required. The air filter is in an accessible location in the cool zone in front of the radiator panels so there are no obstacles to removing it. The generously sized air filter is designed for a long service life. Coarse dirt particles are removed in the filter housing, further extending the cleaning interval.
