RX 400 GL Krone RX 400 GL Specifications & Technical Data (2016—2022)

RX self-loading and harvester-filled forage wagons

RX is KRONE’s latest generation of forage wagons. Offering capacities between 36 and 43 m³, these machines serve two purposes – as self-loading and as controlled-unloading forage wagons but also as silage trailers in the transport fleet serving the forage harvester. The optional 30.5-inch tyres offer a higher load bearing, easier pulling, better soil protection and enhanced road safety. This versatility is paired with an outstanding reliability and efficiency, making the RX a particularly productive machine.

The forager filled RX 360 GL/GD

The sturdy steel structure and the high 20 t gross axle weight rating make the RX 360 a dependable and cost-effective silage trailer in the haulage fleet that supports the forage harvester.

Being filled by the forage harvester

Offering volumes of 40 or 43 m³, an extremely high unloading rate and an impressive 24 t gross weight, the RX models make ideal silage trailers to run in the haulage fleet serving the forage harvester. Filled either by its pick-up or the SP forager, the RX wagon serves two purposes and is therefore a particularly productive machine.

The load area

The RX dual-purpose forage wagons with steel structures are made to excel in the toughest conditions. Choose a pivoting headboard or a rigid headboard with a top hatch to optimize the machine’s filling capacity. Unloading, the heavy-duty chain-and-slat floor feeds even heavy forage swiftly and consistently to the rear.

The pivoting headboard

The RX 400 and RX 430 models have a hydraulic headboard which pivots to various positions to support the filling process. For example, when the machine is filled by a forage harvester, the headboard pivots all the way forward to maximize the capacity and cut out the risk of losses. By comparison, when the machine is gathering material through the pick-up, the headboard is nearly vertical to optimize the filling process. Once the load area is filled, the headboard pivots towards the tractor to expand the load area by 4 m³, simply by using the space above the rotor. This way the RX runs much closer behind the tractor than other wagons of the same capacity. To speed up unloading, the headboard can pivot back and forth and support the work of the floor chain.

The headboard hatch

The RX 360 has a straight vertical headboard. When the combination is following the forage harvester, the tractor operator can open the top hatch towards the tractor for easier filling. The same hatch opens backwards when the machine is gathering crop with the pick-up.

The chain-and-slat floor

Four high-tensile and tube-steel floor chains with channel steel slats are driven by two hydromotors – one on either side of the machine – and advance quickly, fast and effectively clearing out even very heavy material. The chain-and-slat floor slopes at its front end, thereby shortening the passageway into the machine and reducing the strain on the crop as well as the input power whilst boosting the intake rate.

The lights in the load area

To improve visibility during the small hours and night, the loading area is lit by four LED light bars.

The automatic loading system and auto fast mode

For greater operator comfort and relief, the machine can be specified with optional sensors that start and control the chain-and-slat floor automatically. A sensor on the headboard measures the pressure that is exerted by the material, ensuring the machine is used to capacity during pick-up loading. Another sensor measures the current angle of the hatch when the filling level is high. When the preset pressures are exceeded, the chain-and-slat floor is started automatically. Depending on the current load, the auto fast mode switches the floor chain to a higher speed to speed up unloading.

The self-loading RX 360 GL/GD

The wide pick-up and cut-and-feed rotor feed the material effectively through a short feed chamber and across the full width of the load area. Arranged in close proximity to the wide rotor tines plates, the blades on the cutting system give scissor-like cuts.

RX picking up forage from the ground

The extra wide pick-up and feed rotor fill the load area quickly and uniformly, feeding the material through a wide chamber into the load area that can be expanded by pivoting the headboard. It is the extremely narrow gap between the blades and the feed tines that accounts for the superior cutting quality (scissor-like cuts).

The drawbar

Their long and slim drawbar gives the RX models extra agility for manoeuvring in tight turns. The standard suspension for the articulated drawbar absorbs shockloads and offers maximum operator comfort. Two massive rams on the articulated drawbar raise the laden machine and increase its ground clearance on the clamp. An optional automatic system stores and retrieves the two drawbar positions automatically.

The KRONE EasyFlow pick-up

The EasyFlow pick-up excels by virtue of fast, clean and thorough gathering – at high work rates and even in difficult conditions. More than that, the rugged EasyFlow with very few moving parts gives an exceptionally dependable performance.

The pick-up

Offering a work width as wide as 2 m, the EasyFlow pick-up effectively gathers even wide swaths and feeds the material in an extraordinary consistent flow to the feed rotor. Pivoting and spring-loaded, EasyFlow provides perfect ground contouring even in very rough terrain.

Double tines

The 6.5 mm diameter tines with large coils are particularly hard-wearing. Six rows of tines arranged in a wavy pattern ensure there is always the same number of tines in work, which eliminates load peaks and spreads the material consistently across the full working width.

The guide wheels

The EasyFlow pick-up is guided by two small side-mounted gauge wheels. Adjusted without tools to alter the pick-up height, the guide wheels are castering and can pivot flexibly for effective tracking in curves without scuffing. Two extra guide wheels at the rear are an option for EasyFlow for optimum ground contouring in very difficult conditions and on boggy terrain.

The rotor

The KRONE cutting rotor is designed to give exact cuts in large volumes of crop. The 88 cm diameter rotor works at a width of 176 cm and has its tines arranged in helical rows. The tines have 22 mm wide hard-wearing plates and strippers made of high-tensile Hardox steel. The design ensures that the tines feed any crop dependably through the rows of blades, achieving precise scissor-like cuts and filling the machine fast and evenly.

Weighing system

The optional weighing system uses sensor pins on the chassis and on the articulated drawbar to determine and store the weight of the load.

The crop press roller

The crop press roller supports the work of the pick-up by ensuring the crop is gathered cleanly and in a consistent flow. The height is adjusted easily to suit the current crop, the swath volume and ground speed.

The KRONE cutting rotor

The cutting rotor on the RX forage wagons offers many advantages. Powerful and low-maintenance, the rotor operates very smoothly and feeds the crop super gently and consistently into the machine. The rotor blades give exact cuts, stay sharp for a long time and are very easy to replace.

The rotor drive

The rotor is driven by a massive and enclosed spur gear. The rotor is driven by a massive and enclosed oil-immersed spur gear capable of withstanding extreme strain.

The blade cassette

The blade cassette lowers hydraulically and swings out to the side for convenient blade replacement. After the blades are unlocked on a central lever they are removed and swapped conveniently.

Blade group control system

The central blade group control system controls the cutting length. The operator selects the blades in sets of 46 or 23 to achieve nominal chop lengths of 37 mm or 74 mm. When all blades are retracted there is no cutting.

The individual blade protecting system

Each blade is individually protected by a tensile spring, the tripping force of which can be adjusted centrally and steplessly. After the blade has tripped, it resumes automatically its cutting position.

The KRONE on-board electronic system and the operator terminals

The KRONE Comfort electronic system brings fun to field work, making the dual-purpose RX forage wagons easier to use and faster, too. The wagons can be operated from two different terminals that cater for two different applications.

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 (WTK) and CCTV camera for added comfort.

CCI 1200 terminal

CCI 1200 is the universal terminal for ISOBUS-compatible machines. Offering a large 12-inch colour touch screen and all Delta functions, CCI 1200 allows users to split the screen to see all machine control elements on one screen and the camera footage on the other.

Existing third-party terminals

If the tractor has an ISOBUS terminal, you can use this to control the electronic system on RX. In this case, there is no need for a KRONE terminal and operation is even more convenient.

Forage Wagon Features

The sturdy 36 m³ steel structure, the headboard with its hydraulic hatch, and the massive running gear with tandem axles and a steered rear axle make the RX 360 a full-fledged dual-purpose forage wagon. It can also be ordered as a GD version with solid steel sides and discharge rollers at the rear or as a GL model with solid steel sides but no discharge rollers.

Safe road travel

The long and slim drawbar, the tandem axles, the steered rear axle, and the short chassis give the RX 360 outstanding agility for safe manoeuvring in fields and on public roads.

Safe road transport

The long articulated drawbar and the steered tandem axles with hydraulic levelling optimize the machine's ride and stability in the field and on public roads.

Attachment, drawbar and chassis

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 comfort and safety to the operator. Specified with ball hitch, articulated drawbar, tandem axles, and tyres that suit individual conditions, an RX dual-purpose forage wagon is the machine of choice for excellent performance in all applications and conditions.

Tractor attachment

All RX models hitch to a bottom-mount 80 ball. Approved for tongue loads of up to 4 tonnes, these machines offer great agility at minimum wear.

The Tandem running gear

The rear and front axles in the tandem assembly are levelled hydraulically for a uniform weight distribution at all times, ensuring smooth rides and optimum stability. A range of tyre options is available to suit all harvest conditions, and sloping mudguards prevent the crop from collecting.

Steered rear axle

A mechanical forced steering system is available as an option on the rear axle. The steering rod makes headland turns easier, reduces scuffing and tyre wear, and is easily unlocked for quick attachment and removal. The forced steering system is set up and controlled with the help of pressure gauges. An electronic forced steering system is also available, allowing operators to intervene in the steering, for example, in sloping fields or on the clamp, to counter drifting.

Unloading via discharge rollers (GD version)

The discharge rollers unload the material in very uniform mats. Available in sets of two or three, the bottom rotor always spins at a higher speed. All rotors in the assembly have their tines arranged in a 'V' and are driven by the clutch-protected tractor driveshaft, a concept that makes for efficient and fast unloading.
