Having undergone a major facelift, the new KRONE BiG X 480/530/580/630 series models step out in style presenting the best of two worlds – tried and tested technology and innovative features. Apart from the new cab, the facelift focused on the optimised crop flow system and the move to Stage V emission standards.

New and high-comfort cab

The modified models now have a spacious cab that was sourced from the BiG X 680-1180 models and is available in two levels of specification: The standard-fit Premium cab has a terminal with 8″ touchscreen  and USB and camera ports. It also has a sun blind and wiper on the front window and two wipers on the side windows.

The optional Premium Comfort cab offers a leather clad steering wheel, a 12″ terminal with touchscreen and USB and camera ports, a cooled thermos box and sun blinds on the front, right and rear windows. The front window is kept clean by three wipers, the side windows by one wiper each and the rear window by one wiper, all being supplied with screen wash, ensuring operators enjoy 360-degree view of the machine and its attachments even in poor visibility conditions like rain or dust. Naturally, each cab version comes with a choice of comfort seats and halogen or LED light packages for optimum visibility at dusk or night. The package  can be complemented by optional lights on the steps and service points.

OptiMaxx CornConditioner with boosted friction surface area

Excellent forage takes an excellent quality of chop. Like the BiG X 680-1180 series machines, these modified models have the new OptiMaxx CornConditioner with teeth angled at 5°. The helical cut produces a shearing effect that gives intensive conditioning not only lengthwise but also transversely. Like all KRONE corn conditioners, the rollers measure 250mm in diameter as standard while roller length increased by 25% for a 25% larger friction surface area and most intensive treatment of kernels and fibres in all LOC ranges.

Available in two versions with 105/123 teeth or 123/144 teeth, the  105/123 tooth unit is ideal for medium and long LOCs whereas the 123/144 tooth conditioner is recommended for short to medium chop lengths. The speed difference is 30% as standard and 40% or 50% as an option.

Both CornConditioner versions are also available in heavy-duty specification with surfaces treated with the innovative Busa®CLAD technology for best wear protection and maximum service life in all harvest conditions.

The roller conditioner also impresses in terms of handling: The housing is mounted in heavy-duty bearings that withstand the enormous throughputs and offer exemplary ease of service and maintenance with bearings being easy to replace and pulleys easy to swap (to change over from a 30% to up to 50% speed difference). Cleaning the unit is equally straightforward thanks to large openings.

Another plus point is the massive and strong spring pack that allows the rollers to exert a consistently high pressure on the material. Frictional and reliable connection is provided by a standard-fit 6-groove drive belt.

The VariQuick system allows operators to change rapidly from kernel cracking to grass conditioning for  maximum flexibility and productivity in corn, GPS or grass.

Clean engine and narrow road width

All models are powered by tried and tested MTU engines of up to 653hp and all comply with Tier 4 final (USA) and Stage 5 (EU) emission standards. Mounted sideways, the engine sits right at the back for optimum weight distribution. Efficiency and fuel economy are implemented by the direct driveline to the crop flow system. On a side note, the BiG X 630 with MTU 6R 1500 engine is more powerful now (480kW/653hp).

Another strong selling point of these Big X models is their narrow transport width: Even when clad with 710/70 R42 tyres, these foragers measure only 3m in width for safe and convenient travel on public roads.

XtraPower 50 for Big X 480 and 580

The XtraPower assistance system is a unique and world-first KRONE innovation, a practical feature that brings maximum flexibility and books extra engine power into the machine depending on requirements and local harvest conditions. After the purchased machine is registered, the extra power is immediately enabled at and ready for retrieval whenever necessary. Available in 10 to 250 drum hour packages, XtraPower can only be retrieved in field work – so the extra engine power is used only on demand. No power is wasted. When no additional engine power is required, the driver selects “Pause” on the terminal and the machine returns automatically and immediately to its previous output level.  


Data management included

Another standard feature on the new Big X is an easy-to-use data management system which allows operators to use KRONE Smart Telematics from the customer web portal or the agrirouter, the universal data exchange hub. This way, the new BiG X models meet all modern data management requirements including machine data analysis, job logging and billing.

  • Convenient disc gap adjustment from the cab



A KRONE exclusive

  • Consistent performance with irregular crop flow
  • Extremely smooth running even on uneven swaths
  • High throughput
  • Top quality chop
  • Extremely user-friendly

Outstanding quality chop even in an uneven crop flow: The spring-loaded cutterhead floor is connected to the anvil of the counterblade at the front. This means that the clearance between the cutterhead floor and the knives is always constant. So any movement of the spring-loaded cutterhead floor to compensate for an uneven crop flow won’t affect the quality of chop.

Consistent throw with a tight crop stream: The spring-loaded backplate of the crop accelerator ensures maximum crop output in all conditions, filling the trailer to perfection.



EasyFlow 300 S, 380 S

The camless pick-up

  • More output, quieter running, less wear
  • Stepless speed adjustment from the cab
  • EasyFlow speed automatically adjusts to driving speed
  • Quick coupler with curved bracket for easy attachment and removal and excellent ground tracking
  • Six rows of tines arranged in W shape

Two work widths: Working at widths of 3 or 3.8 m using six rows of tines arranged in a W shape, the camless KRONE EasyFlow 300 S and 380 S pick-ups are extremely powerful and thorough. Depending on the swath width and your working speed, you can vary the speed of the EasyFlow steplessly from the cab. Alternatively, the speed can be automatically matched to your driving speed. The curved retainer bracket allows for a wide pivot range and makes the header easy to attach and remove.

XDisc 620

The direct cut head

  • 6.2 m work width
  • High throughput, low input
  • KRONE EasyCut disc mower technology – proven the world over
  • KRONE SafeCut: unique protection for mower discs
  • Powerful auger with replaceable Hardox wear plates

Cutting and chopping in one pass KRONE XDisc is the versatile specialist mowing unit for whole crop silage. It cuts the crop cleanly without wastage. The huge 900 mm diameter auger makes BiG X enormously powerful and has no trouble picking up very long, bulky material.

Safe as houses: If the system is suddenly overloaded, instead of the impact being directed fully onto the spur gears on the cutterbar, a roll pin in the sprocket drive shaft shears. A thread on the sprocket drive shaft jacks up the disc, lifting it out of the danger area and above the cutting paths of neighbouring discs. SafeCut protects the spur gear driveshaft and the neighbouring discs against damage. The roll pins can be replaced in just a few minutes and cost next to nothing.

SmartCut: stripe-free mowing – Because the mower discs turn in both directions, the disc paths must overlap precisely to ensure a clean cut. So there is a greater overlap between the cutter blades that rotate away from each other – perfect for stripe-free mowing. The larger gap between the blades rotating backwards ensures efficient output of large quantities of forage.


Efficient and effective

  • Variable-row widths of 4.5 – 9 m
  • Top quality chop, fewer overlength fractions as stalks are fed in lengthwise
  • Simple design reduces power input
  • Central drive shaft

Unique, powerful and efficient: Cutting at widths of 4.5 m to 9 m, the BiG X 480, 530, 580 and 630 models can take two or three-section maize headers that work at variable row widths. The continuously rotating collectors feed the stalks to the middle of the machine, where they are turned through 90° and pulled in lengthwise. Ideal for a top quality chop with fewer overlengths.


The engine

Powerful and fuel-efficient

  • 6-cylinder in-line MTU engines
  • Tier 4 final / Stage IV emission standard
  • Maximum constant engine outputs from 490 to 626 hp
  • Extremely economical, smooth running

BiG X 580 and 630 PowerSplit: PowerSplit adapts the engine output automatically to the harvest conditions. EcoPower is used in situations in which less engine power is needed. XPower delivers maximum output for tough conditions. This technology gives you more flexibility and saves fuel.

In-line engines mounted sideways: The engine is located right at the back of the machine and is mounted sideways for optimum weight distribution. The direct driveline to the crop flow components translates into great fuel economy. Common Rail injection technology makes these MTU in-line engines highly fuel-efficient.

The driveline


Strong and reliable

  • Simple design
  • Direct power transmission with extra strong poly V-belts
  • Long service life
  • Separate drive shafts on intake system and headers Reverses when cutterhead idle
  • Separate reliable hydrostatic pump drive

Clever design: The header and intake system are driven via oil pumps flange-mounted onto a gearbox driven by the engine via an extra strong poly V-belt. This concept allows the header and intake speeds to be adjusted steplessly.

Ground drive: The hydrostat pump is powered via a 5-groove poly V-belt driven separately by the engine which starts up automatically when the engine starts. The direct driveline works reliably, guaranteeing maximum safety.

Direct driveline – full throttle: The transversely mounted engine allows the hydro pump, the cutterhead, the crop accelerator and the header and intake pumps to take engine power efficiently off poly V-belts, eliminating the need for a power take-off gearbox. All crop flow components are activated via a belt clutch.

The running gear


Innovative drive train

  • Front wheel drive as standard, four-wheel drive optional
  • Strong Bosch Rexroth wheel motors
  • Traction control with three travel modes
  • Stepless speed range from 0 to 40 km/h

Front-wheel drive – four-wheel drive: BiG X 480, BiG X 530, BiG X 580 and BiG X 630 are available with optional hydraulic four-wheel drive via wheel motors. Machines with front-wheel drive have hubs on the rear wheels instead of wheel motors. Both drive trains are designed for speeds of up to 40 km/h.

Planetary gears: The wheels are powered by Bosch-Rexroth planetary gearboxes. This type of gearbox has the advantage that it spreads the load across several planetary wheels, delivering high torques in a compact unit.

A KRONE exclusive: The front wheels feature eccentric, height-adjustable wheel motors to maintain the position of the pick-up, intake system and cutterhead floor for the next pass, regardless of the size of the wheels. So an optimum, constant crop flow is ensured at all times.

Completely manoeuvrable: This drive concept with wheel motors has an extremely small steering angle of just 50° – perfect for tight turns and matching up to the previous row on headlands with an 8-row maize header.

Tyres with a purpose: The BiG X 480, 530, 580 and 630 models can take tyres up to 900/60 R 42. Large tyres ensure maximum ground clearance, lowest soil compaction and an extremely comfortable ride.

Kitted out well


Down to the very last detail

  • Best night vision
    Optional LED lighting kit
  • Huge optional spare fuel tank: carry up to 1450 l diesel
  • Easy access to service and maintenance points

Turn night into day: Sixteen headlights light up your work area perfectly, making night shifts less stressful and safer. An optional LED lighting kit enhances visibility even further.

Up to 1,450 l fuel on board: The huge, basic specification fuel tank holds up to 1,220 l diesel. And there’s also room for 115 l urea on board. So there’s no need to stop what you’re doing to refuel. An auxiliary 230 l diesel tank and a 275 l silage additive tank are available as an optional extra.

Everything within sight: The optional LED maintenance lights give a clear view of all drive assemblies and maintenance points in the dark. Optional LED lights are also available for the access ladder.

Plenty of room: There’s plenty of room between the cooling system and the crop flow on the BiG X 480, 530, 580 and 630 models, giving easy access to all components for cleaning and maintenance.

The cab


The ultimate level of comfort

  • Spacious
  • Maximum operator comfort
  • Excellent all-round vision

Wider, quieter and brighter: The wide cab with its narrow posts is spacious and gives the operator the best possible view of wide headers. The double floor keeps noise in the cab to a minimum. Sixteen H9 lights provide perfect illumination, and LED lights are available as an option.

Everything within sight: High side windows and slim posts give the operator an unobstructed view of the spout even with filling heights as high as 6 m, making filling trailers safer and more efficient.

Ergonomic, convenient and easy to use: The ergonomic joystick with user-friendly icons gives the operator fingertip control of multiple machine functions. Designed specifically for BiG X, the slim stick sits comfortably in the hand. With more than 20 programmed functions, it not only controls ground speed and direction of travel but also the header and spout.

Clutter-free: The controls for lights, heating and air conditioning are arranged on a panel above the front windscreen. The Follow-Home function lights your way as you get down from the cab. After you switch off for the night, some headlights stay switched on for several minutes, allowing you to find your way safely.

Little helpers: The control box records all the machine data and displays it on the high-definition colour screen. Various settings can be changed on it, such as stepless LOC adjustment. The clearly designed control unit next to the seat houses all controls that operate the various machine functions, including ground drive and cutterhead drive.



DigitalSystems is the electronic control system from KRONE that optimizes machine utilization and operator comfort. It gives peace of mind in tough conditions and displays all relevant harvest data.

AutoScan: The photo-optical sensor in the middle of the maize header measures the maturity of the plant and automatically adjusts the LOC. Green maize is cut to longer lengths for a better structure and to reduce silage effluent in the clamp. When harvesting dry maize, the material is cut to shorter lengths for more effective compaction in the clamp. AutoScan reduces operator effort and saves fuel, because the stalks are only cut as short as necessary and not as short as possible. AutoScan comes as standard with all KRONE machines and is not an expensive extra.

ConstantPower: ConstantPower automatically adjusts the machine‘s ground speed to the engine loading. Select the desired engine loading at the touch of a button and the machine will adapt its ground speed fully automatically to the crop and material being harvested. This standard feature reduces operator stress and ensures maximum throughputs with minimum fuel consumption. In combination with AutoScan, this system takes the overall quality of chop and machine performance to a whole new level.

ForageCam: As an optional extra, a CCTV camera on the spout remotely transmits footage to the forager’s in-cab terminal and to the terminal on the trailer. The CCTV camera helps the operator utilize the full load space in the trailer and reduces fatigue at the same time. The system can be expanded to communicate with multiple receivers on all the trailers in a large haulage chain.

RockProtect: The six pre-compression rollers are powerful and soft at the same time. The optional RockProtect system provides intelligent protection from damage by stones as it halts the pre-compression rollers fully automatically within milliseconds after the system detects a stone. The operator sets the sensitivity of systems. More protection – more peace of mind.

ISOBUS autoguidance: As an optional extra, BiG X can be supplied ready to accept various manufacturers’ ISOBUS guidance systems. On the move, the operator activates autoguidance using the KRONE joystick simply by pressing a button, then watches the system guiding BiG X down the track. Autoguidance reduces operator fatigue, boosts work rates in broadcast seeded crops and increases efficiency.

NIR crop moisture sensing system: The optional NIR sensor provides exact information on crop moisture levels. The information can be allocated to the area harvested in the customer memory. The NIR sensor is easy to install on the BiG X spout and is protected from damage by a cover.

CropControl: The optional KRONE CropControl yield metering system measures the volume of crop harvested quickly and accurately at the touch of a button. With CropControl you can seamlessly document yield information on all fields harvested.

AutoCalibrate: AutoCalibrate is the re-mote calibration tool for the BiG X‘s yield metering system. It operates via a weighing system installed on one of the trailers in the harvest chain. Both the trailer and the BiG X forager are equipped with data loggers that communicate via a mobile network. Calibration takes place while the ‘calibrating machine’ is being filled. AutoCalibrate is highly accurate and is the first system of its kind to eliminate the trip to the weighbridge.
