Quality six times over

  • 6 pre-compression rollers for a top-quality chop
  • Hydraulic drive shaft: LOC steplessly adjustable from the cab
  • Adjusts automatically with AutoScan
  • Maximum protection against foreign objects: The long path from the metal detector to cutter head
  • Metal detection across the entire chamber width

Constant, safe, and convenient Six pre-compression rollers and an 820 mm gap between the leading roller with the metal detector and the rearmost roller not only enhance pre-compression but also protect the knives better against metal objects at high-speed intake.

The hydraulic drive shaft automatically adjusts the LOC in line with the maturity of the crop, which is detected by the KRONE AutoScan sensor. If the engine speed drops below 1200 rpm as the load increases, the header and intake system are stopped automatically while the cutter head continues to turn – because blockages caused by too low speeds cost time and money.

The system for your success

  • Perfect kernel treatment
  • Huge 250 mm diameter roller
  • Roll gap adjusted conveniently from the cab
  • Perfect treatment: the right teeth for your corn

KRONE corn conditioner cracks every kernel: The 250 mm diameter rollers have a larger friction surface area than the smaller diameter toothed rollers and can be operated with a larger roll gap for greater efficiency and fuel economy and better long stalk conditioning. The speed difference between the two rollers is 20% or, optionally, 30%.

Variable roll gap: The roll gap is adjusted steplessly from the cab in a range from 0.5 to 10 mm via an electric motor. The operator can see the current setting on the display.

Standard toothed rollers: The rollers on the standard corn conditioner have 105, 123, 144, or 166 teeth. The huge 250 mm diameter rollers allow you to step up your work rates and forage quality levels.

Hard chrome coating: Featuring 250 mm diameter rollers with 105, 123, or 144 teeth, the chrome-plated corn conditioner is exceptionally durable and will give you an extremely long service life.

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 cutter head floor is connected to the anvil of the counter blade at the front. This means that the clearance between the cutter head 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 the 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.

Adjustable crop throw 

  • Optionally adjustable crop throw
  • Tight crop stream even with a long crop throw
  • The shorter the crop throw, the less power is needed
  • Fill the trailer accurately with no spillage

Short crop throw: For a short crop throw with the trailer driving alongside, the crop stream leaves the spout at a lower speed. This saves power, which can be used to boost chopping output.

Long crop throw: With the trailer following behind, the crop stream needs to be ejected from the spout at a higher speed. A strong, tight stream is needed to cover the long distance over the tractor to the rear wall of the trailer.

Neat filling – efficient and effective

To avoid spillage while filling the trailer, the crop stream must be tight and the crop throw must be set to the exact distance. The operator can adjust the crop throw from the cab quickly and easily by adjusting a hinged flap in the backplate of the crop accelerator. As the accelerator needs less power with a short crop throw, the freed-up engine output can be used for chopping, thus increasing throughput.

Crop accelerator: The paddles are designed for high crop output and guide the crop flow towards the middle.

Adjusting the crop throw distance: The crop throw is controlled via the hinged flap on the backplate of the accelerator. For a short throw, the flap is tilted out of the crop flow, so there is little contact between the crop and the accelerator. For a long throw, the flap is tilted into the crop flow, so there is more contact between the crop and the accelerator.

Joystick control: The crop throw is quick and easy to control with the buttons on the joystick control panel.

Armrest buttons: Additional control buttons are provided in the armrest for extra convenience.

Stepless electric motor control: The hinged flap on the backplate of the accelerator is adjusted steplessly via an electric servomotor.

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 cutter bar, a rolling 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.

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.

Grass chute or corn conditioner

  • Switch quickly from grass chute to corn conditioner and back
  • Easy change thanks to the drawer system
  • No complicated changeover: done in just a few minutes
  • Corn conditioner is quick and easy to remove

Installing and removing the corn conditioner is quick and easy to install and remove. Once you have disconnected the grass chute, you simply tilt the corn conditioner downwards over the gliding plane. Two hydraulic drums make for easy handling and very fast set-up times.

Drawer format for a quick change: With VariQuick, BiG X can be switched from maize to grass mode and back again in no time. The sliding rail enables the grass chute and the corn conditioner to be moved together as one unit with a hand pump and positioned at the appropriate point in the crop flow. For longer use in the grass, the corn conditioner can be folded down and removed completely to the side.

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 cutter head 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 cutter head, 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.

Innovative drive train

  • Front-wheel drive as standard, and 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 cutter head 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.

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 gives 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 color 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 cutter head drive.
