AX 280 HL Krone AX 280 HL Specifications & Technical Data (2017—2022)

The load area

The sloping floor on AX increases its throughput rates and minimizes tractor input. The extremely robust chain-and-slat floor offers stepless adjustment of its advancing speed, a feature that has been asked for by many farmers.

Height control at your fingertips

The articulated drawbar offers hydraulic height control which can also be operated from an optional button on the headboard. The optional auto control feature allows operators to retrieve the stored field/road position of the drawbar easily and fast. The latter increases the ground clearance by up to 60 cm for easier manoeuvring on the headland or clamp.

The pick-up

The camless EasyFlow pick-up has only few moving parts and runs extremely quietly, causing little wear. Boasting a wide work width, it gathers wide swaths tidily also in bends. Undulations are no problem at all, thanks to the pivoting suspension along with the gauge wheels. Working at a width of 1.8 m (to DIN 11220), the pick-up gathers wide swaths no problem and feeds the material to the rotor cutter in a very consistent flow. Excellent ground contour following comes from the pivoting suspension and the leading gauge wheels that pivot sideways and also offer height control without tools.

Perfect control

Your can order two optional gauge wheels to run at the rear and outside the tractor wheelings to optimize contouring and minimize contamination in very difficult conditions.

Delta terminal

The Delta terminal has a 5.5-inch touch screen, a touch pad with 12 function keys and one dial. From here, operators control all loading and unloading functions, collect and store machine data and carry out diagnostic routines. They can also connect an optional joystick (AUX) and a CCTV camera for added comfort.

More operator comfort

The CCI 1200 operator terminal with 12-inch touchscreen offers the same features as the Delta terminal plus it allows operators to split the screen in two views. For example to see all machine control elements in one view and the camera footage in the other.

Consistent crop flow at all times

The crop press roller has a chain that allows operators to easily adjust the work height to ensure a uniform and consistent crop flow in varying crops, swath volumes and at varying ground speeds.

Strong tines

The 6.5 mm diameter double tines with large coils are particularly hard-wearing. Arranged in a wavy pattern, six rows of tines feed the material from the ends to the middle of the rotor, thereby preventing crop from building up as the machine travels through bends, for example, and spreading it evenly across the full width of the rotor cutter.

Powerful and low-maintenance operation

Powerful and low-maintenance, the AX rotor cutter operates very smoothly and gently. The blades give exact cuts, stay sharp for a long time and are very easy to replace.

The rotor

Measuring 760 mm in diameter and offering a working width of 1.47 m, the rotor cutter was developed for filling a high-capacity wagon. Its tines are arranged in six helical rows and have 25 mm Hardox plates for long service life. The scraper elements, too, are made from hard-wearing Hardox steel. The design ensures the tines feed the crop dependably through the blades for precise and scissor-like cuts and fast and uniform fills.

The blade cassette

When all 32 blades are set to cutting action, the system achieves a nominal chop length of 45 mm. The blade group control system allows operators to select the blades in sets of 32, 16, 16, 0.

Operated from one lever

After the blade cassette lowers and the blades are withdrawn to '0' position, operate a lever on the left side of the machine to remove the blade cassette.

Pulling out to the side

After the cassette is released, it easily pulls out and swings alongside the machine for easy blade removal and replacement.

Locked in place automatically

After the blade cassette moves back into its working position, it locks home automatically on the right machine side.

Universal Forage Wagon

The large choice of available extensions makes the KRONE AX a universal forage wagon. Collapsible hay extensions allow the AX to enter low buildings or pass under low gates, whereas steel extensions give it a head start as a self-loading forage wagon. Additionally, it can take silage extensions, including the headboard hatch, which make it the perfect dual-use forage wagon and silage trailer.

Collapsible hay extensions (FL / FD)

The AX 250 L/D model has hay extensions that collapse hydraulically. With the extensions down, the machine easily passes under low gates. The top ropes, the slide cover in the front section, and the rear cover ensure no material is lost in transport.

Steel extensions (GL / GD)

All AX forage wagons are available with the extra strong steel extensions. The crop is secured with top ropes that ensure nothing is lost during transport. The steel tailboard is operated automatically by two single-acting rams.

Silage extensions (HL / HD)

The AX 280 and 310 can be specified with optional silage extensions. These include a silage hatch at the top of the headboard. Operated hydraulically, this flap moves forward for filling from the forager ahead. Without top ropes, the AX suits not only applications in which the material is collected by the pick-up but also when the wagon is filled by the forage harvester.

Robust design

The forage wagon is a heavy-duty machine thanks to its channel-steel frame. The hot-galvanized and powder and plastic coated sides are high-quality and extremely durable. The sloping mudguards avoid crop collecting here.

Perfect pick-up loading

The chain-and-slat floor slopes 100 mm at the front, which reduces the length of the feed channel and thus the amount of power required to feed the material into the load area, enabling a faster and gentler crop feed.

The KRONE automatic loading system

No matter whether your AX self-loading wagon has the entry-level auto loading or the optional PowerLoad system, each system ensures the machine is filled to capacity whilst maintaining compression at optimum levels. With the wagon filled to capacity in each haul, you are cutting down on your transport costs.

The automatic loading system

This optional system activates and controls the chain-and-slat floor with the help of sensors. One sensor measures the pressure that the material exerts on the headboard, while another sensor at the top of the headboard scans the current angle of the silage hatch. The chain-and-slat floor is started automatically as soon as the pressure scanned equals the set pressure. Depending on the crop, it is also possible to use the two sensors independently of each other.

Using both sensors

The PowerLoad floor chain varies its speed relative to the pressure that is detected by the sensor on the headboard. This system helps distribute the material evenly and preserve an optimum feed quality. Operators can enter the target pressure on the cab-based terminal.

The KRONE on-board electronic system & operator terminals

The KRONE on-board electronic system clearly enhances the operation of the AX forage wagon. Available in Medium and Comfort specification, the system is operated from various terminals, each catering for different applications and needs.

Alpha control unit

This is the base specification level for the AX forage wagon – the Medium on-board electronic system complete with the Alpha control unit, which operates the pick-up, the articulated drawbar, the chain-and-slat floor, and the tailgate.

Suspension system, drawbar and running gear

Varying harvest conditions, difficult situations on the clamp, high payloads, and long-distance travel at speed call for a running gear and a drawbar that offer maximum strength and stability as well as superior operator comfort and safety. Choose between the top-mounting hitch ring, the bottom-mount pivoting drawbar, the ball hitch or the articulated drawbar. This and the caster-steer tandem axles with either mechanical or hydraulic suspension allow you to specify your machine to your individual needs.

Ball hitch

The bottom-mount ball hitch 80 brings great agility, minimizes wear and offers tongue loads of up to 3 tonnes.

Suspended drawbar

A suspended drawbar is available as an option on the AX and is a particular boon during long-distance travel on bumpy roads.

Great stability

The caster-steer axle assembly with hydraulic auto-levelling has two separate hydraulic circuits. The system reduces the risk of machine roll when working in sloping fields or travelling through bends. The AX manages undulations with ease as the oil flows from the cylinder on the front axle to the cylinder on the rear axle and vice versa to compensate for roll. This way the machine weight is uniformly distributed to all wheels as the machine is entering the clamp.
