• 3D contouring in any direction
• Best possible 3D contouring for all tines
• Clean forage, no losses

The KRONE Jet Effect ensures the tines will not dig into the ground when the rotors lower and lift. Emulating the touch-down and take-off behaviour of an airplane, The clever design of the rotor suspension ensures there is always a maximum of clear space between the tine and the sward when the rotor lifts and lowers out and into work – an intelligent system that helps protect the sward and avoids crop contamination.

The rotors suspend in a pull-type and cardanic configuration which provides exact guidance to the tines and optimum contouring – both in and across the direction of travel. This way the tines pick up every haulm but not a single grain of sand. Uncontaminated forage, minimum loss rates and high work rates - this is the Swadro definition of quality work.

The Swadro rotors are pulled in direction of travel. Its pull-type suspension in combination its central arrangement allows the rotor to stay level when lifting and lowering. Its weight is uniformly distributed to all gauge wheels, ensuring optimum contouring and minimizing contamination and losses.

• Sealed and maintenance-free rotor gearboxes
• Fuel-efficient gear ratio
• Lubricated for life with fluid grease

 The Swadro rotor gearbox is powerful and yet frugal in terms of tractor power. Thanks to its large gear ratio, Swadro requires only low pto speeds at minimum wear. Compared to other swathing systems, Swadro rotary rakes stand out for low input power and great fuel economy.

The weather sets the pace in forage harvesting. Maintenance- free and permanently liquid greased rotor gearboxes make the KRONE Swadro a very reliable partner in your harvest campaign. Swadro is always ready to go, ensuring dependable operation in narrow harvest windows. No time is wasted on service stops. Come rain or harvester.

No matter how difficult the conditions, the Swadro rotor gearboxes deliver reliable performance and great stability without any servicing or maintenance. Count on these qualities.

• Gauge wheels on high flotation tyres run very close to the tines
• The largest wheelbase on the market
• Adjuster changes the rotor angle across the direction of travel for optimum swaths and loss-free rakes.
• Caster steer wheels at front and rear (option) protect the sward

The wheels under the KRONE Swadro rotors never lose contact with the ground, not even the roughest terrain. The largest possible contact area and pivoting range in combination with suitable tyres ensures no blade is left on the sward and the sward is not damaged. Clean and intact swards are the cornerstone for top quality forage also from the next cut.

The guide wheels on the bogies run very close to the tines for effective guidance and contouring. As the wheels cover a large surface area, the tines pick up every single blade without contacting the sward. In addition, every model has individual setting options that help adjust the bogies to the specific conditions. The leading wheels are castering. High flotation tyres are options for soft and boggy terrain and two extra wheels are available for each rotor for work in very rough pastures.

An optimum rotor tilt across the direction of travel translates into minimal losses and boxy swaths. All Swadro rotors tilt as a standard feature. The lateral tilt controls the position of the tines relative to the ground and is set on the rear wheels of each rotor. In fact, the rotor should tilt slightly towards the swath in order to balance out the load the material puts on the tines. KRONE recommends a 1-2 cm tilt toward the swath.

• Maintenance-free
• Special Bainite hardness
• Dry cam track

The KRONE cam track features the unique Bainite structure which is obtained by a special hardening process. Accordingly, this cam track has a very durable surface and yet a flexible core, a combination that results in low wear. This type of coating also reduces rolling resistance for reduced friction, wear and power input.

Stand-out features of our DuraMax cam track is the extremely small diameter and steep track design. It is this unique design and its effect that lead to the formation of optimum swaths in all conditions. The small diameter of the cam track combines with the massive size of the rollers for smooth and low-wear operation. As the tine arms follow the steep curve the tines are promptly lifted out of work, forming boxy and optimum swaths in all conditions.

• Maximum stability and reliability
• Wear-free and gap-free folding arms
• Swift changeovers
• Pre-machined notch

Maximum stability and reliability The Swadro tine arms set the benchmark in terms of durability and reliable operation. The massive design of the arms with pre-machined notches makes these arms stand out in the rotary rake sector, because it withstands the highest loads and brings peace of mind in extremely difficult conditions

Each tine arm is controlled by its control shaft that is manufactured to precision-fit tolerances for exact fit in the control arm and precision tine control as the arm follows the cam track. It is this design that leads to those clean and lossfree rakes. Each tine arm is mounted on two ball bearings inside the hub plate. The two bearings are spaced wide for stable and smooth control of the shaft as well as reduced wear and higher work rates. The main part of the tine arm is the thick-walled and maintenance-free tube which is permanently and wear-free connected to the control shaft for reliable tine control without play. This is the secret behind optimum tine control and quality rakes.

Some KRONE Swadro models have foldable tine arms either as a standard feature or an option for reduced transport heights. This unique folding mechanism reduces the transport height and width in a matter of minutes without requiring the operator to remove the arms and carry them to their holder on the machine, reducing the strain on the operator and saving time and money when changing fields. Belleville springs inside the arms connect the two parts reliably and fast, a solution that eliminates potential wear of a locking pin or hole. At the same time, the connection is gap-free and very durable to give reliable operation in many harvest seasons.

• Clean forage thanks to the Lift Effect
• High driving speeds without losses
• Increase in forage quality
• Reduced losses

All current ­KRONE Swadro models have the ­KRONE Lift Tines as standard specification. Kinked in two positions, these tines offer significant benefits that have been verified in ­KRONE field tests and a DLG Focus Test.

For more than 10 years, the KRONE Lift Tine has convinced our customers around the world in terms of quality forage and rakes. Kinked in two positions, the vertical tine lifts the material clear off the ground. This is the secret behind producing clean forage in difficult conditions. The Lift Effect sees the grass moving up the length of the tine. Even extremely wet and heavy material will not bend the tines which are up to 10.5mm thick and are coiled around large-diameter arms for greatest stability and tidiest rakes.

DLG confirms: Less contamination and fewer losses in the raking pass

• We place greatest importance on clean forage and an excellent raking
  quality. Therefore, we seek scientific evidence in confirmation to our
  visual assessments..
• Consequently, we submitted the KRONE Lift Tines to a DLG Focus Test in
  order to assess the level of crop contamination and rake quality and compare
  the results with other tine systems.
• The results were indeed very clear: The KRONE Lift Tines reduce crop contamination
  with raw ash to levels of less than 9% - at any forward speed.
• In addition, the special design of the tine reduces losses by up to 2.1%
  compared with other systems. Losses never reach 1.5% of the total crop
  yield, not even when work rates are high

• Flexible working widths. Maximum throughputs on forage wagons, balers and foragers
• High rotor lift-out on the headland. No disturbance of voluminous swaths
• Maximum operator comfortfor relaxed working on long harvesting days

Even swaths, high acreage output, clean raking paired with flexible adjustment options for all conditions are convincing arguments for the Swadro TC and TC Plus rotor rakes from ­KRONE. At the same time, the Swadro TC Plus offers the greatest possible operator comfort for the driver, so that even long working days can be approached in a relaxed manner.

All Swadro TC rotors have their work height adjusted down to the millimetre. This is done on a crank which is arranged on the outside of the rotor for easy access. A large scale helps operators to read the current position.

Those who often use the rake in varying conditions will find it helpful to opt for the electric rotor height control system. This is standard specification on all Swadro TC Plus models. From the cab-based control box, operators control two servomotors which change the rotor height conveniently and accurately. This control box also displays the current working height and raises the rotors individually.

Swadro TC 640 and TC 760 come with a standard mechanical working width control. The arms are extended and retracted to the required work/swath width by operating a crank.

All Swadro models from TC 880 onwards are adjusted hydraulically to the proper work width (option on TC 640 / TC 760). This is done from the convenience of the cab and assisted by a clear scale on the arm.

The rotors can be lifted out independently. This is standard specification on the TC 930 and TC 1000 and an option on all other Swadro TC models. This feature brings great advantages in wedges and along boundaries.

Strong coil springs transfer some of the weight to the main beam and the chassis as the rake is swathing along – for light treading on soft soils and clean rakes in any situation.

Swadro TC 1000 / TC 1000 Plus: Die zwei größten Modelle im Bereich der Zweikreisel-Mittelschwader bieten eine Arbeitsbreite bis zu 10,00 m. So werden auch Feldhäcksler und Ladewagen optimal ausgelastet. Eine Besonderheit beim TC 1000 ist die Federentlastung inkl. Einkreiselaushebung sowie das Sechs-Rad-Fahrwerk in Serienaustattung. Der TC 1000 Plus verfügt über ein Acht-Rad-Fahrwerk. Durch das Sechs- bzw. Acht-Rad-Fahrwerk wird der 4,20 m große Kreiseldurchmesser optimal entlang der Bodenkontur geführt. Durch die Kombination dieser Kreiselfahrwerke und der entsprechenden Kreiselentlastung bleibt auch beim Swadro TC 1000 / TC 1000 Plus das Futter sauber und kein Halm liegen.

The Swadro TC 680 has a fixed 6.80 m work width, which makes it the ideal rake to work ahead of a compact round baler or forage wagon, producing swath widths that suit a narrower pick-up on a smaller harvester for optimum efficiency and cutting quality.

KRONE is the only manufacturer who markets twin-rotor centre delivery rakes which can rake all the material. To disturb and aerate dry and light material, Swadro TC 680 and 760 can be equipped with a KRONE development – the disturbing rotor. Positioned in the middle of the rake and carrying six tines, the hydraulic rotor disturbs and aerates all the material in the middle of the machine between the left and right rotors. This promotes uniform wilting and boosts the quality of hay and leafy forage such as lucerne.

The high-clearance frame and the high rotor lift-out allow the machine to run over massive windrows without disturbing them.

Swadro TC and TC Plus are attached to the two-point headstock by a ball bearing joint and a rod-steered undercarriage with articulated steering. This patented combination makes this KRONE rake a particularly nimble machine – a boon in awkward areas where no crop is left behind and shunting is eliminated. The machine simply goes into every corner of the field without manoeuvring. The articulated steering is an option on the TC 640.

The chassis of the Swadro TC rakes have standard 10.0/75-15.3 tyres and the ones on TC 880, 930 and 1000 run on 11.5/80- 15.3/10 PR tyres (left photo). All models from Swadro TC 680 can be fitted with 15.0/55-17/10 PR (right photo) tyres that suit softer soils or sloping fields. Both models offer a transport width of less than 3.00 m and the TC 640 can be clad with special AS tyres.

If the wheels are fitted with slim tyres, it will be possible to expand the track width by 6 cm (2.4"). Simply refit a distancer sleeve on the wheel arms and move each axle out 3 cm (1.2").

Great road stability and exceptional castering are the stand-out features of the chassis that is approved to 40 km/h (25 mph). Quick changeovers bring drown the transport height to less than 4 m (13'2"), fold up the rotors without removing any tine arms (except TC 1000) or guards and retract the telescoping arms to reduce the machine width.

• A controlled material flow through the machine for best rakes
• Boosted outputs from the forage wagon, baler or forager
• No roping for maximum harvester performance

­The KRONE Easy-Line increases rotor rpm on the leading units by about 25% compared with the rear units, so the leading rotors present the material in a wider mat to the ones at the rear which rake it into fluffy and boxy swaths. The Easy Line driveline ensures the material doesn’t drop back on the ground once it has been picked up. This explains why even the multiple- rotor rakes in the KRONE Swadro range ensure gentle treatment and minimal contamination even when several rotors work in sequence.

The KRONE Swadro four-rotor rakes have purely mechanical drivelines where every rotor is individually protected from overload for maximum protection from total machine failure. The drive power flows efficiently from the patented crash box on the leading rotors to the rear rotors. The straight driveline not only reduces the strain on the universal joints but also improves fuel economy.

• Entry-level four-rotor rake with variable 9.80 m to 12.50 m widths
• ­KRONE Easy-Line drive system: perfect swaths for baler, loading and forage transport wagon and forage harvester
• Simple and quick adjustment of the raking height with direct display of the set height
• Comfortable field change without getting down from the cab to under 4 m height and under 3 m width
• Precisely and infinitely adjustable hydraulic relief for optimum ground contouring
• Single-rotor lifting mechanism: ideal for swathing on wedge-shaped tapered surfaces

With the new Swadro TC 1250, ­KRONE enters the field of large area technology. Powerful components of the large professional machines combined with the simple operating philosophy of the twin-rotor rakes make the Swadro TC 1250 the ideal all-rounder for self-mechanised farmers, machinery syndicates and contractors.

The working width and also the swath width are adjusted hydraulically as a standard feature for fast adaptation to varying conditions. The arms telescope rapidly to the correct working width – wide when gathering the last cut for presentation to the forager or narrow for the forage wagon and round baler.

The TC 1250 with two-point headstock pivots in the lower links for smooth and stable rides on roads and in the field. Turning through a large angle, the headstock makes for tight headland turns and effective rakes in corners, a feature that saves valuable time in narrow harvest windows.

The operator sets the height of each individual rotor manually on the crank and reads the current height on the large scale.

Swadro TC 1250 features a modern and appealing styling with a trapezium frame and massive tube steel arms that ensure high stability and longevity. The sloping panels keep the machine clean and country roads, too.

Compact by design, less than 3 m wide and less than 4 m high without folding the tines, this rake makes for convenient and safe travel between fields.

The transport wheels are clad with 500/50-17 tyres as a standard. Wider 620/40 R 22.5 flotation tyres are available as an option, offering a larger contact area for gentle treading and minimum compaction in softer soils.

In work, strong coil springs shift the weight of the rear rotors to the main beam and the chassis, thereby taking load off the rear rotors. By comparison, the front rotors have hydraulic suspension which is set steplessly on the on-board spool chest by switching from lift-out to suspension and vice versa, allowing the machine to adapt easily and conveniently to any terrain – for cleanest swaths and best forage quality.

The TC 1250 is entirely operated from the KRONE control box. Functions like individual rotor-lift out, swath width control or telescoping front arms are selected on the control box and executed by the tractor spools. Thanks to this selector box, the machine requires only one single-acting and one double-acting tractor spool. This gives you maximum operator comfort from an entry-level tractor.

The front and rear rotors are lifted out via sequence control. The shift gate on the front arm allows operators to alter the timings in line with the current forward speed and their needs. Highest acreages and yet maximum operator comfort. The leading rotors can also be raised individually as an option. In this specification, the operator pre-selects a rotor and then raises it by operating the tractor spool. After that, the sequence control system raises the opposite rotor and the rear units. Perfect rakes in the most awkward shaped fields. Another option allows operators to raise/lower the leading and rear rotors in pairs – either sequence controlled or in front/rear pairs.

• Variable work width from 10.80 m to 13.70 m
• Hydraulic rotor suspension
• Integrated vibration damping with Soft-Down automatic lowering mechanism
• Electric rotor height adjustment with two storable height settings
• Wide tyre package with 710 transport tyres and 16x9.50 rotor tyres optional
• Hydraulic beam control for less than 4.00 m transport heights
• ­KRONE Easy-Line drive concept for optimum swath shape and best raking quality

The four-rotor rake centre delivery Swadro TC 1370 not only comes in a modern design, but also with numerous technical highlights. These include convenient setting and adjustment options which greatly facilitate work and ensure optimum swathing results with high acreage output.

Telescoping hydraulic arms adjust the positions of the two leading rotors left and right separately. This way, the rake can vary its working width from 10.80 m to 13.70 m to adapt to varying field conditions. The rotors resume their previous positions automatically when lowering into work.

The swath width is adjusted irrespective of the work width by varying the distance between the two rear rotors between 1.40 m and 2.20 m. As another key feature, the tine arms on the rear rotors have five double tines which optimize the work and quality for the following harvester.

The hydraulic rotor suspension that is integrated in the lifting cylinders provides gentle treading also in difficult conditions. The system is set up steplessly and conveniently from the tractor and separately for the leading and rear rotors. The new and integral Soft-Down drop rate control lowers the rotors particularly softly into work – a boon for the quality of feed.

The operator controls the work height from the terminal so there is no need to dismount the tractor. You can either adjust all rotors at the same time or each rotor separately. Also, you can program two different heights to the system and retrieve them later by fingertip control.

620/40 R 22.5 transport tyres are standard specification. But you can also opt for hydraulic brakes and wider 710/35 R 22.5 tyres to improve the performance in boggy terrain. Both tyre sizes are small enough to ensure that the 40 km/h machine doesn’t exceed the statutory 3 m transport width.

The rakes that run on standard transport wheels have caster-steer bogies with pivoting wheels that are clad with 16x6.50-8 tyres. The rake can also take the wider 16x9.50-8 tyres on the bogies provided the tyres on the transport running gear are the optional 710/35 R 22.5 size. Both tyre sizes are also available for 6-wheel bogies with rear tandem axle.

You can set and retrieve separate lift-out heights for the leading and rear rotors from the tractor terminal. More than that, you can set the lift-out height and also time the front and rear lift-out according to the prevailing conditions, making the most of narrow harvest windows.

The beam lowers hydraulically to a transport height of less than 4 m, meaning you don’t have to fold or remove any tine arms.

The TC 1370 is attached to the tractor via the pivoting two-point headstock which allows the machine to follow tractor roll for agile manoeuvring. But you can also opt for a bottom-mount 80 ball hitch.

The operating structure of the Swadro TC 1370 combines clarity and convenience. Regardless of whether the tractor's ISOBUS terminal, the CCI 800, CCI 1200 ISOBUS terminals or the ­KRONE DS 500 are used, the entire machine can be set up on just two operating levels.

The SectionControl feature lifts and lowers the individual rotors separately to avoid multiple rakes in awkward patches. The feature reduces operator stress and boosts productivity thanks to faster headland turns.

With the DS 100, KRONE offers a simple operation unit for the Swadro TC 1370. In combination with a UT terminal on the tractor, the DS 100 can be used as a convenient operation unit, for example directly on the armrest of the driver's seat. As an alternative to the DS 100, the ISOBUS-compatible CCI A3 joystick can be used in the same way for comfortable, fatigue-free operation of the Swadro TC 1370.

• Variable work widths 10.00 m to 19.00 m
• Stepless swath width control from 1.60 m to 2.80 m
• Automatic rotor overlap control
• Intelligent steering of the transport chassis

With the Swadro TC 2000, ­KRONE is setting standards in terms of acreage output and raking quality. With a flexible working width between 10.00 m – 19.00 m, acreage outputs of up to 20 ha/h are possible. The enormous working width reduces the overall length of the swaths by up to 30 % and therefore also reduces the number of passes of the following harvesting chain per ha to a minimum. In addition, the Swadro TC 2000 increases the recovery performance of the following harvesters by up to 15 %. This means that the forage harvester or loading and forage transport wagon is always optimally utilised, especially in cuts with low growth.

The rake can vary its work width between 10.00 m and 19.00 m hydraulically, producing swaths that match the capacities of the following harvesters. To do that, the two arms extend and retract on a sliding carriage so the two rotors in the pair will always rake up the same amount of material, producing uniform and consistent swaths that suit exactly the capacity of the following harvester.

Not only is it possible to adjust the working widths to needs but also to adapt the swath width. This is done by adjusting the rear rotors hydraulically and steplessly between 1.60 m and 2.80 m which is preset on the terminal. The technology helps form perfectly boxy and high-volume swaths for round balers and forage wagons.

The automatic folding feature: A hydraulic sequence control manages the individual steps, taking off stress and strain from the operator.

The compact DS 500 terminal has a 5.7" colour display. Operation is either via the twelve function keys or via touchscreen according to the driver's needs. Using the optional ISOBUS joysticks makes operation even more convenient. This relieves the driver in the best possible way, even on long working days.

With the CCI 800 and CCI 1200 operating terminals, ­KRONE offers two ISOBUS-compatible touchscreen terminals with an 8" or 12" colour display. In addition to the main screen, up to two other screens can be displayed alternately. For example, it is possible to switch between the assignment of the joystick, the Section Control function or a camera image while working.

The use of the automatic part-width Section Control reduces the driver's workload considerably, especially when swathing wedge-shaped areas. It detects areas which have already been worked and automatically raises the rotors, thereby preventing the same area from being worked twice. This optimally relieves the driver and allows him to fully exploit the performance potential of the Swadro TC 2000, even on long days.

The axle on the transport chassis is switched off during work This feature ensures uniform and straight swaths that keep the following harvester happy.

The steered axle is activated automatically when the rotors are being lifted out of work. At this moment the chassis is steered via a rod – a detail that ensures maximum agility in headland turns and cuts turn-around times.

The extra cylinder on the steering linkage helps manage narrow field and farm gates and clear awkward patches. This means that even the smallest field entrance can be mastered without manoeuvring.

The Swadro TC 2000 is pulled over the lower links of the tractor. The movable headstock Cat. II/III compensates for uneven ground. The stable support jack ensures a high degree of stability when parking.

Running on big 800/45 R 26.5 tyres for good road stability, the transport chassis is approved for road travel at 40 km/h In addition, the ground pressure is kept low and the sward is sustainably protected.

The Ackerman steering system on the transport chassis can be operated in two ways: either passively via a linkage or actively via a hydraulic ram. Excellent castering, manoeuvring in tightest space and easy steering are the qualities that make this chassis stand out from everything else.

The extra hydraulic steering system will be appreciated by those who seek tighter turns to manage narrow gates and by those who do a lot of countersteering in sloping fields. A hydraulic cylinder on the steering linkage adjusts the turn angle or ride behind the tractor.
