Big Pack 4x4 Krone Big Pack 4x4 Specifications & Technical Data (2011—2026)

Variable Fill System

With the Variable Fill System KRONE once again offers a solution to improve a farmer’s productivity. This is another classic example of the innovative force that characterizes KRONE designs. The VFS system combines the best features of continuous feed systems with the best features of volume-dependent systems and opens up completely new ways for KRONE balers to produce exceptional large square bales.

A new rear end

The rear end on the BiG Pack High Speed model features a substantially beefier frame to accommodate a hitch that allows bale collectors to be attached more easily.

Compressed air cleaning

The air pipes are arranged so that the entire knotter area is kept clean. Compressed air cleaning guarantees consistently high reliability of the knotters – even under extreme operating conditions.

Compressor onboard

Tractors that do not have compressed air systems, with KRONE no worries as you will get an onboard compressor as standard equipment. Compressed air keeps the knotters clean in all conditions, in all countries. Plus it has a quick coupler so you can blow down the machine yourself after the day's work.

The secret lies in the details

The new KRONE BiG Pack 4 x 4 High Speed delivers dramatically higher throughputs than its predecessor. The secret behind this is the 36 % larger feed chamber with a brand new VFS Variable Filling System. The four packer arms and the feeder arm are now equipped with more tines than ever before.

Strong rotor, strong cut

The large diameter of 550 mm (1'10") is impressive. The double tines in sets of three across the full width of the cutting and feed rotor pass the crop efficiently across the knives because of the V-shaped arrangement.

Wide Hardox plates on the feed tines

They result in higher throughputs, clean scissor-like cuts and harder wearing. The 20 mm (0.8") wide Hardox feed plates are a guarantee for quality forage. Any mushing is eliminated.

Finest quality cuts!

Select 16 or 26 knives to achieve nominal cutting lengths of 44 mm (1.7"). The knife control system activates half of the number of knives or deactivates all knives. As a result, the machine is conversed without tools and in no time at all. The feed tines are arranged in a V and are plated with wide Hardox steel to provide finest cuts, highest throughputs and maximum longevity. The knife floor is adapted to match the crop flow and increases machine efficiency.

The “Tray Principle”

The X-Cut cutting system has two knife drawers with either 8 or 13 knives. The drawers can be lowered hydraulically to install and remove the knives. For this purpose, the knife drawers or “divided trays” can be conveniently pulled outwardly to the side. The exposed knives can be removed for maintenance work or for changing the cutting length. The knives can then be refitted, all without tools!

Quick and easy

The central knife control system sets a variety of cutting lengths. Select half the number of knives to obtain a nominal length of 44 mm (1.7"); select the full set of knives for a length of 88 mm (3.5"). 0 position means the crop is not cut.

Chopping at its best

The cutting rotor is 525 mm (1'9") in diameter and features 88 pivoting knives in a helical arrangement. Rotating at 3,000 rpm, it feeds the material through a counter blade and on to the pick-up. The counter blade is made up of two bars, each equipped with 47 rigid knives. The bottom bar adjusts to one of five positions, the top knife to one of three, and all knives are reversible for a long service life.

X-Cut

The demand for cut straw is increasing. One more reason for optional equipment on the BiG Pack 1290 HDP X-Cut system with the proven 26-knife cutter. The number of knives can be selected from 0 to 26. With the knives in, you will achieve higher bale densities and finer cutting, which is desired by pig or poultry farmers for easier distributing.

Watching the moisture

Optional sensors are fitted in the side doors and transfer their measurements to the terminal, keeping the operator constantly up to date.

Delta Terminal

With the Delta Terminal, KRONE offers a convenient display that makes it easy to control and monitor the attached KRONE machine. The easy-to-read colour touchscreen gives the operator a full overview of all machine functions. In addition to that, the device is able to operate the machine on the basis of tractor data – provided this is specified accordingly – for example to automatically lock the steered axle when the combination reverses.

Towards a digital future

With the ISOBUS BiG Pack, KRONE customers can already make a huge step towards a digital future today. Yet it’s up to you how many steps you want to take at a time. The KRONE Delta terminal is extremely easy to operate and offers a colour touchscreen, which makes all machine data readily viewable. The inclusion of the ISOBUS CCI Terminal in your order opens up virtually unlimited potential.

ISOBUS tractor terminal

All ISOBUS machines from KRONE can be operated from an existing ISOBUS tractor terminal. Simply connect the baler to the tractor terminal and use the same familiar interface. In addition, control units such as the WTK joystick can bring further ease of operation, depending on tractor specification.

As an alternative

Further flexibility in tractor mounting is provided with a drawbar ball (K 80 system) coupling system. Whether using this system or the standard drawbar mounting system, the KRONE BiG Pack balers are designed to fit all makes of tractors.

Machine options

Everything under control: You can opt for a reverse-drive CCTV system that comprises a camera and a colour screen, which has a second port for a second camera. The CCI Terminal is also compatible with the camera.Documentation: Documentation is becoming more and more important in modern farming, especially when the bales are produced for customers abroad. To cater for these situations, KRONE offers a bale tagging system that is available for all KRONE big balers and that automatically attaches an RFID chip to every finished bale. The chip contains all important information, which can be read with a scanner as often as required.Harvesting quality: The optional moisture sensor updates the operator on the current crop condition, displaying the information on the cab-based monitor. The system gives an alarm whenever a preset parameter is exceeded.The precise weight: Would you like to know whether the bale weight meets the requirements of your customers? Then, the optional bale chute with integral weighing system is just the right technology for you. The terminal now displays not only the weight of every single bale but also the total weight of the finished baling job.

BiG Pack with variable feed system

I like the feeding system on the KRONE baler. It seems to be more gentle on the hay. The maintenance part of the KRONE baler is very attractive as well; the auto lube system greases everything but the drivelines. It’s also a very smooth running baler, which equates to less wear.

KRONE BiG Pack

With the KRONE BiG Pack, you are always one step ahead. Baling up to 25% heavier bales with the BiG Pack HDP model and tying up to nine small bales into one big bale with the MultiBale system, you will be ahead of the field, using first-time innovations that you won’t find anywhere else.

BiG Pack: The product line that secures Success

With a KRONE large square baler you purchase experience and competence in baler design. From experience KRONE knows the widely differing field requirements and offers a complete baler range with standard bale chamber dimensions. Internationally recognized innovations, such as the Variable Fill System (VFS), the unique MultiBale model and the camless EasyFlow pick-up are some reasons for the success of the KRONE BiG Pack. It is a fact: KRONE makes what customers want.

BiG Pack 890 (X-Cut)

The smallest of all BiG Packs. With four double knotters and Bale chamber dimensions of 80 cm (2'7.5") height and 90 cm (2'11") width, this machine has proven itself, not only in straw, but also in heavy wet Silage.

BiG Pack 1270 (X-Cut)

This machine is used in conditions because of its chamber dimensions of 120 cm (3'11") height and 70 cm (2'4") width. Six Single or Double Knotters provide for well-shaped baling in Straw, Hay and Silage.

BiG Pack 1270 (X-Cut) MultiBale

With this version you can pack up to nine small bales in one large bale. Your benefits: The large bales can be cleared quickly from the field and the small bales can be easily distributed.

BiG Pack 1290 (X-Cut)

The firm bales with 90 cm (2'11") height and 120 cm (3'11") width is accepted by farmers worldwide. Because of the large bale dimensions, this machine works mainly in straw and hay, but in some countries it is commonly and successfully used in silage as well.

BiG Pack 1290 (X-Cut) HDP

Make bales like bricks. The High Density baling system and the longer bale chamber lead to an increase in bale weight by up to 25 % over traditional systems. This pays for itself quickly when transporting straw.

BiG Pack 4x4 (X-Cut)

With 130 cm (4'3") chamber height you are making fewer bales per acre, saving time and labor costs and clearing the field quickly. This baler is used mainly in straw and hay and can be equipped with the X-Cut cutting system.

Rock Solid Bales

The Variable Fill System (VFS) from KRONE provides rock solid and well-formed bales, even in small windrows and at reduced forward speeds. The principle of the VFS system: First, the packer and feeder tines convey the crop into the feed chamber where it is collected and pre-compressed. At the point when the feed chamber is completely filled, the feeder rake conveys the crop into the bale chamber.

The density is maintained across the chamber width

As one sensor on either wall measures the actual force of the stroke. A control system compares this measurement with the parameter set by the operator and corrects the pressure exerted on the chamber doors as necessary.

Powerful and safe

The KRONE big balers have extremely long plungers, which support the work of the needles. The plunger on BiG Pack 890 operates at 50 strokes/min, the plunger on BiG Pack 1270 and 1290 at 45 strokes/min and the unit on BiG Pack 4 x 4 at 38 strokes/min, ensuring quiet and smooth operation.

The funnel shaped bale chamber is the answer

For highest bale densities the BiG Packs have long, funnel-shaped bale chambers with spring loaded hay dogs on the sides and top. The round ends of the doors guarantee smooth bale edges.

Bale for bale, consistency in length

The star wheel is mounted in a central location in the bale chamber floor. The bale is pushed over the star wheel providing an exact bale length measurement.

Full hydraulic power for rock solid bales

Up to 6 hydraulic cylinders (depending on machine model) operate the upper and side bale chamber doors for highest continuous loading in the bale chamber and bale ramp.

In best shape

BiG Pack will be the baler for you. Produce rock-hard bales of uniform densities and with tidy and smooth edges. These are the qualities that made BiG Pack famous. The on-board hydraulic system with automatic baling force control ensures the shape is maintained and the edges are tidy, even in moist conditions and varying crops. The long funnel-shaped baling chamber with its haydogs to temporarily retain the crop warrants highest baling densities.

Simple and robust by design

The BiG Pack balers have a hydraulic bale chute as standard specification. The chute may be fitted with an optional and integral weighing system.

The double knotter function

During the baling process, upper and lower twine strands are fed to the bale. These are tied together at the start (starting knot 1) and at the end (ending knot 2) of the bale that is being formed. The lower twine is guided through the needle by a tensioning system that surrounds the bottom and the two ends of the bale. The upper twine is supplied to the bale directly by a tensioning system and does not run through the knotter like a Single knotter. This ensures that the machine can be driven with maximum baling force in all crops without dropping strings.

Always a perfect knot

Highly compressed and well-tied bales are always guaranteed with the KRONE knotting system. This knotting technology operates with six knotters (four knotters in the BiG Pack 890) with absolute reliability. All KRONE large square balers with more than 700 mm (27.5") bale chamber height have double knotters as standard. The BiG Pack 1270 is available with single knotters or optionally with double knotters.

Sure-footed

In storage position the machine is set down on a hydraulic height-adjustable parking jack. The hydraulic parking jack is available as standard for the BiG Pack 1290 HDP and BP 4x4. It is optional for all other balers.

BiG Pack 890 VFS (XC)

Standard equipment is four double knotters, seven spring loaded hay dogs in the bale chamber and three hydraulic cylinders for the upper and side bale chamber doors. Because of the narrow chamber width, the X-Cut cutting system has a maximum of 16 knives.

BiG Pack 1270 VFS (XC)

For highest baling densities this machine has seven spring loaded hay dogs in the bale chamber and four hydraulic cylinders for the bale chamber doors. It is possible to choose between single and double knotters.

Balers that do not compromise

The KRONE large square balers are classic examples of exceptional baling density, output and comfort. With their different chamber dimensions and many unique features, the BiG Pack 890 VFS (XC), 1270 VFS (XC) and 1290 VFS (XC) work in worldwide conditions with absolute success in straw, hay and other crops. With a KRONE large square baler you have the right machine in your fleet: Reliable, powerful and designed for versatile application. Your customers enjoy well-shaped bales and you enjoy satisfied customers.

Large becomes small

During operation the driver sets the required small bale on the control panel in the tractor cab. The bale length of the small bales can be set continuously from 45 cm (1'6") to 135 cm (4'5") on the control terminal of the Comfort controller. The smaller single bales are bound by two strings, while the entire bale is tied with four strings. Naturally, you can also work with conventional full-size single bales, all tied with six strings.

MultiBale – An EXCLUSIVE from KRONE

Up to nine single bales in one large bale. The award-winning MultiBale method simplifies handling. The length of the small bales can be adjusted from 30 cm (1') to 135 cm (4'5"). In operating the MultiBale, a conventional large bale, up to 270 cm (8'10") long can be baled, which contains up to nine smaller bales. The MultiBale system provides its owner with access to a wider customer base and outstanding flexibility in bale packages.

An operator’s dream come true from KRONE

The MultiBale system for KRONE BiG Pack large square baler 1270 VFS (XC) with double knotters and Comfort controller. With MultiBale, the field is quickly baled and large bales made of small bales can be delivered to the customer. The length of the entire bale as well as the number of small bales can be set conveniently and simply on the terminal in the tractor cab. The MultiBale system has become a very popular model straight after its introduction to the market, because it has filled a significant need and wish of contractors and farmers. To make small conventional bales from a high output large square baler, to reduce costs, time and handling.

For highest density

The plunger is designed and reinforced for maximum strength to withstand the highest loads. Six hydraulic cylinders generate the force on the side bale chamber doors allowing the operator to make rock solid large bales.

The world’s biggest square bales

KRONE BiG Pack 4 x 4 is the ideal machine to get fields cleared quickly and efficiently. A 4ft x 4ft baling chamber produces bales of 3.20 m (10'6") in length and 5 m³ in volume – there is no other machine that can match this. These massive bales suit farming needs as well as industrial applications.

The integral pre-chopper

PreChop is the integral pre-chopper for the KRONE BiG Pack 1270 XC, 1290 XC und 1290 HDP XC big baler ranges. Equipped with 88 rotary knives and two fixed counter banks of knives in a staggered arrangement, the unit chops the crop to nominal lengths of 21 mm (0.8"). More than that, PreChop defibrates the stem visibly. The defibrated crop flows smoothly through the baler and is baled into well-shaped bales that are easy to handle.

A modular system

So you want to use a PreChop system on your BiG Pack XC big baler? No problem, because your baler offers the flexibility to do just that. Its drawbar extends to provide sufficient space between the chopping unit and the tractor’s rear wheels. The chopper itself is activated/deactivated conveniently from a mechanical gearbox. You can also use the baler without the PreChop unit: Just raise it 52 cm (1'8.5") clear of the ground and run over swaths without the PreChop unit picking them up.

Easy removal

You can easily remove the PreChop unit when you don’t want pre-chopping for an extended period. Simply remove the pins and the driveshaft and then pull the unit out to the side on its transport rolls.

BiG Pack High Speed – baling at two different pto speeds

KRONE BiG Pack High Speed helps you to respond to any situation and application. Operate your BiG Pack baler at 1,000 rpm and 45 strokes/minute in big swaths and reduce pto speed to 800 rpm and stroke frequency to 36 strokes/minute when baling in low-yielding crop. At either speed, the bales are as hard as rocks while fuel consumption goes down.

High load capacity

The plunger is centered in the chamber by the huge bearings. It can be adjusted in height by eccentric adjustment bolts through the bearings. Plus scrapers are equipped front and back of the bearings to clean the track out for that extra reliability.

Suitable for all tractors

The V-shaped drawbar is sturdy, adjustable in height and highly maneuverable when driving around the tightest corners. The PTO shaft is supported by an intermediate bearing position between the baler and the tractor providing a noticeably quiet, smooth operation of the shaft.

Flying high

The huge bevel gearbox in combination with the nearly 600 kg (1,323 lbs) flywheel can cope with more than 830 kW/1100 hp and efficiently absorbs peak loads on the plunger. The slip clutch is arranged in front of the flywheel to protect the driveline on the tractor while a cam clutch protects the machine’s driveline.

Starting off easy

KRONE offers a hydraulic starting aid for its 1290 HDP and 4×4 BiG Pack big balers. A hydromotor accelerates the almost 600 kg (1,323 lbs) flywheel to more than 300 rpm before the tractor pto is engaged – obviously, from the cab terminal.

With full load

Rising fuel prices and highway toll charges increase freight costs dramatically. For this reason it is very important that a truck with a permissible gross weight of 40 t is fully loaded, as the costs remain the same even if the payload is not fully utilized. Tests have shown that up to 5 tons more can be loaded with the HDP bales. The calculation is quite simple: At an unloaded weight of the truck of 15.5 t you come to 24.5 tons load with HDP bales 500 kg (1,102 lbs) in weight, to only 19.5 tons with bales 400 kg (882 lbs) in weight.

BiG Pack 4 x 4

KRONE BiG Pack 4 x 4 – that’s the formula for a huge 4ft x 4ft baling chamber and a host of innovative details. The bigger pre-chamber and the completely redesigned EasyFlow pick-up with active drive accelerating roller results in throughputs that are unprecedented. The massive, high-momentum flywheel and equally massive gearbox compress the material up to 38 times per minute, making rock-hard bales – powerfully and gently at the same time. KRONE BiG Pack is the formula for sheer efficiency.

EasyFlow: The camless pick-up in a large square baler

With the EasyFlow pick-up, KRONE offers for the first time a camless pick-up that functions without a complex cam track control. The secret of this pick-up is the wave-shaped design of the tine bands, which provides the effect of tine retraction without the cam track drive. EasyFlow can work at 30% higher speed, allowing for increased ground speed and throughput.

The advantages are obvious

The EasyFlow pick-up has clearly fewer moving parts due to the elimination of the traditional cam drive design. This results in lower wear, leading to reduced maintenance and service costs. EasyFlow operates at approximately 30% higher speed compared to conventional systems. An improved throwing effect enhances the crop’s transition from the pick-up to the bale chamber, thereby improving the pick-up’s capacity and making the BiG Pack even more efficient.

Maximum Pick-up capacity

Making a great feature even better is the continuous crop flow provided by the roller crop guide with an integrated deflector plate. The forage is not pushed upwards; instead, it is pushed onto the tines, which is crucial in lumpy windrows. This design ensures consistent crop flow and full utilization of the exceptional pick-up capacity.

The solution for higher operator comfort

The drive through universal shaft with an integrated ratchet clutch responds to pick-up overload, eliminating the need for changing shear bolts.

Direct-Drive

The cutting and VFS rotor is driven directly off the main gearbox. Drive protection is provided by the integrated cam-type clutch, which protects the cutting rotor against overload and resets itself automatically.

X-Cut safety

The spring protection for individual knives ensures trouble-free operation if foreign objects are picked up. The knives conveniently push back into their working position after the foreign body has cleared.

Exceptional protection of the entire drive

At the front, the BiG Pack is protected by a friction clutch. In the case of overload on the machine side, an automatic ratchet protection clutch is activated.

Without diversions

The power transmission to the packer gear and the knotters occurs directly through drive shafts instead of chains, which are prone to wear and tear and require maintenance. Customers can be assured of comfort, convenience, and reliability with the KRONE direct drive system.

Self-contained, onboard hydraulics

The hydraulic circuit is supplied from a separate onboard oil tank through a high-pressure pump driven by the main gearbox. This means the oil circuit is independent of the tractor hydraulic system, thus eliminating a possible source of contamination.

Good lubrication saves on repairs

The established standard automatic lubrication system has been expanded on the BiG Pack 4 x 4 and now also lubricates the pick-up chains. Of course, this does not mean that any of the other grease points are neglected.

The tandem axle with a parabolic sprung boogie

The large swing distance gives advantages when in transportation and also reduces the ground pressure as it transmits uniform pressure onto the ground.
