- Good stability of the parked machine thanks to front and rear support jacks
The KRONE Vendro tedders impress by stable rides
and convenient changeovers that are executed
from the seat. With the rotors folded in, the rotary
tedders are compactly mounted on the tractor
and can be easily moved and parked to save space
thanks to the favourable centre of gravity.
The prop stand at the rear counterbalances the stroke of the damper struts as the machine is removed from the tractor. The stands raise the wheels from the ground avoiding tyre damage from long periods of storage.
In storage position the tedder rests on two wide stands rather than on its own wheels. In this position, it is also easily attached and removed from the tractor.
The tedders have mechanical or hydraulic damper struts depending on specification. Hydraulic dampers are available for all machines as an option. They bring the booms together – gently – as the machine is being raised out of work. Vibrations are absorbed directly so that the machine follows the tractor without rocking, even when cornering. so that every single blade of grass is picked up and tedded into perfect forage.
The headstock offers various coupling positions for the top link to implement various work heights. The top link goes in the elongated hole on those machines that have the leading gauge wheel. This type of attachment gives optimum contouring and ensures the material is picked up and spread cleanly and in a wide mat.
The V-shaped and compact supporting frame of the tedder ensures that the centre of gravity is very close to the tractor. This results in a low lifting force requirement which also allows smaller tractors to be used. Likewise, the front axle of the tractor is only minimally relieved and the steering behaviour is not impaired.
- KRONE OctoLink finger clutch – eight fingers make frictional Connections
- The driveline to the rotors is never cut
- No risk of driveline damage due to operator error
- Maintenance-free driveline minimises service and maintenance and maximises lifetime
All Vendro tedders benefit from the tried-and-tested KRONE OctoLink finger clutches. The rugged units require no lubrication at all. This is the kind of dependable and low-maintenance machine you have always wanted.
The eight-finger clutches make Vendro an enormous agile machine. They allow the outboard rotors to fold 180° towards the middle without any risk of damaging the driveline. Thanks to this enormous flexibility you can store the machine in tight space and travel at a reduced transport height.
Each rotor is driven by a well-proven finger clutch which consists of eight fingers that make a frictional and reliable connection inside the driveline. No matter which angle, the power flow to the next rotor is never cut off. The extremely robust finger clutches are absolutely lubrication-free, freeing you from time-consuming servicing and making you more productive.
- Standard overrunning clutch in the main gearbox maximises safety when turning off the machine
- Rotor gearboxes
- Maintenance-free and liquid-grease lubricated
- Long service life thanks to permanent lubrication and the cantilevered design
- Reduction gearbox produces small night swaths for faster wilting
The KRONE rotary tedders are designed to deliver perfect functionality. Key elements in this context are the main gearbox with a standard overrunning clutch and the maintenance-free and permanently lubricated rotor gearboxes.
It is possible to operate the rotors at lower speeds to produce narrow night swaths. This is implemented by optional ad-on gearboxes that are particularly beneficial in haymaking. In configuration two rotors form a pair each of which groups the material into one narrow swath that absorbs less moisture during the night and is spread again on the following day. This technique reduces the risk of variations in crop wilt in the same field.
The rotor gearboxes are mounted under the robust frame where they are safe from exposure to the strains of work and operation. Sealed and filled with semi-fluid grease, the boxes are maintenance-free and extremely durable.
All tedders have a main gearbox with overrunning clutch as a standard feature This clutch ensures that the rotary tedder can coast to a stop when the tractor PTO shaft is switched off. instead of stopping instantly when the pto is switched off, eliminating any risk of damage due to overrunning components.
- The rotor wheels run extremely close to the rotor providing optimum contouring
- Curved 3D tines lift and spread the crop perfectly
- Rotors overlap for clean and uniform spreads
- Optimum spreads for uniform wilting and highest-quality forage
The KRONE OptiTurn rotor design make real big-time. The special design sees the rotors overlap generously so the KRONE OptiTurn tines can lift the crop cleanly and spread it uniformly at an optimum width for fast wilts and optimum animal feed. This technology boosts your productivity not only in the field but also in the milking parlour.
The two shafts in one pair of tines are unequally long so their tips are always in parallel as they hover above the ground, lifting the material cleanly and without contamination. This so-called combing effect mixes the various layers of the mat for uniform and consistent wilts.
The tines are attached to the tine arms with an eccentric plate This allows you to alter the tine angle to one of three positions. The proper angle is important for good results in varying crop conditions and field contours.
Der neue dreidimensional gebogene Zinken sorgt für eine optimale Arbeitsqualität. Denn die doppelt gekrümmte Zinkenform verbessert die Aufnahme und Abgabe des Ernteguts – die Basis für sauberes und hochwertiges Futter.
The sturdy tine carriers are firmly bolted to the rotor. Thanks to their round tube profile, they are extremely robust and crop adhesion is effectively reduced. An additional ring underneath the tine arms provides additional stability to ensure that even large harvests are wilted reliably and uniformly.
For consistent spreads in any type of condition, the tine arms of two adjacent rotors overlap generously. A consistent mat of crop speeds up the process of wilting, allowing you to produce high-quality forage in narrow harvest windows.
Clad with big flotation tyres, the rotor wheels run as closely as possible to the tines for optimum contouring, avoiding unnecessary contamination for high-quality forage.
- Big flotation tyres for gentle treading and sustained sward protection
- Optimum rotor control for perfect ground hugging and clean forage
- Stable rides behind the tractor also in curved passes
- Anti-wrap guards protect the wheels in long-haulmed crops
Proper tyres are important in forage harvesting. Therefore the KRONE tedders run on oversize flotation tyres that provide accurate control to the rotor, keeping the crop clean and protecting the sward by minimising the ground pressure.
Anti-wrap guards come as standard on the KRONE rotary tedders, prevent-ing long-haulmed crops from wrapping around the wheels and legs and eliminating unnecessary hold-ups to free them from the grass. These anti-wrap guards can be complemented by extra plates for extra efficacy.
The large tyres in combination with their close proximity to the working area of the tines ensure that the rotors are guided evenly, even on uneven terrain. The tines are prevented from digging into the ground and the sward is protected from damage, thereby ensuring quality forage for the current and subsequent cuts.
- Altering the angle of throw alters the intensity of conditioning
- A steep angle controls tedding, a shallow angle controls turning
- Easy adjustment to 13°-19° angles without tools
Tedding or turning? Vendro allows you to change from tedding to turning or vice versa at the spur of the moment. Simply change the spreading angle and the crop is conditioned at the required intensity.
The spreading angle influences the intensity of forage conditioning: A steep spreading angle results in intensive conditioning and is used to ted the freshly mown crops. However, dry crops are gently turned at a shallow angle. This way you are able to operate the machine to your specific needs.
All tedders have this pin-and-hole system as a standard feature which allows you to alter the spreading angle within a range of 13° to 19°. The spring-loaded pin adjusts the angle quickly and easily in four steps. No tools required, no pins need cottering.
- Standard border spreading control avoids losses along boundaries
- Manual control is standard specification on Vendro 470 to 790
- Convenient hydraulic control from the cab is standard specification on Vendro 820 to 1120 and an option on Vendro 470 to 790 models
- Vendro C models optionally equipped with hydraulic border spreading curtain
We would be saving wrong if we wouldn’t make border spreading control a standard feature on the Vendro tedders. The system spreads the material towards the middle of the machine when tedding along field boundaries. You either set the mode from a straightforward manual control on the machine or hydraulically from the convenience of the cab.
The hydraulically controlled border spreading curtain of the Vendro C models enables forage distribution to be precisely controlled along the edge of the field. Thanks to this system, no forage is wasted and an even broad distribution is achieved.
The Vendro 470 to 790 models feature a manual setting as standard. The operator can adjust the border spreading system from the tractor cabin using a cable pull. For the Vendro 820 to 1120 and Vendro T 900 to T 1120 models, a hydraulic border spreading system is installed as standard (optional for all other models except the Vendro C models). This border spreading system is conveniently controlled from the tractor seat. A central hydraulic cylinder on the linkage enables the running wheels to be swivelled continuously for precise adjustment. This function also enables spreading uphill and ensures that the forage is evenly and broadly distributed, even on extreme slopes.
The Vendro models with three-point linkage and the Vendro T models enable the targeted spreading of forage from the edge of the field inwards thanks to their border spreading system. This means that no forage is lost. The linkage of the border spreading system connects all the rotary impellers and allows them to be adjusted simultaneously.
- Wide range of 4.70 m to 7.90 m work widths to choose from
- Mechanical dampers enhance ride comfort and road safety
- Standard mechanical border spreading feature for loss-free tedding along boundaries
- Headland position pre-setting feature is an option for all models
- Optional front-running gauge wheel for perfect ground contouring in heavy going
Looking for a tedder that offers uncompromised tackle for grassland and pastureland and yet treats your crop gently and makes it wilt fast? Then these machines are for you. Even the smaller machines with four or six rotors are high performers both in hay and heavy crops.
Mechanical dampers cut out sway as the three-point mounted tedder tracks behind the tractor on steep slopes and in curves. They also align the machine at centre and stabilise it in transport position. Mechanical struts are standard specification, hydraulic units are an option.
You can opt for an extra gauge wheel that runs ahead of the line of rotors, optimising their ground hugging ability in uneven terrain, avoiding contamination and boosting the quality of the forage.
The models in this range differ in rotor size and number of tine arms, giving you the perfect choice to buy the outfit that’s best for you, your business and your crops.
- Wide range of 8.20 m to 11.20 m working widths to suit your Needs
- Standard hydraulic border spreading Control
- Standard headland position pre-setting feature on the 10-rotor models
- Big flotation tyres increase ride comfort and reduce compaction
- Hydraulic damper struts ensure excellent tracking and road travel without jolting
The 8- and 10-rotor machines offer many ground-friendly features that turn your crop into high-quality forage whilst minimising losses. All major functions are controlled hydraulically for high operator comfort.
The KRONE rotors are designed to run very close to the tines. In combination with the hinged frame sections and the double beam this translates into perfect ground hugging, minimum losses and cleanest forage.
You can conveniently preset the height to which you want to raise the machine on the headland so the outer rotors have the necessary ground clearance to avoid tedding the same area twice. This is a standard feature on Vendro 1020 and 1120 and an option on all other models.
The hydraulic dampers maintain a stable transport position and ensure quiet running behind the tractor. They also improve tracking in the field for uniform conditioning and optimum spreads.
All 8- to 10-rotor machines have hydraulic border spreading control that is conveniently operated from the cab. The system brings the machine at an angle relative to the border so all material is kept in the field.
- 9.00 m to 11.20 m work widths
- Two-point mounted Vendro T, Vendro C with pivoting drawbar – with three-point attachment as an option
- Standard hydraulic border spreading control - No losses along the edges
- Optimum centre of gravity - smooth ride
The new design of the trailed KRONE Vendro series, coupled with innovative techniques, optimised guards and an unbeatable operating comfort, is a clear statement of what it was designed for: maximum reliability, maximum efficiency and top quality forage!
The Vendro T range comprises three types with working widths from 9 m to 11.20 m. The machines are each equipped with their own running gear, making them ideal for use with small tractors which have little lifting power.
To optimally guide the rotors even on very uneven terrain, a front guide wheel is available as an option for the Vendro T models. This can be mounted on the left, right or both sides of the front part of the frame and can be continuously adjusted in height using a crank handle.
Two double-acting control units are required to operate all machine functions. By using an optionally available operation box, the machine's demands on the tractor can be reduced so that all machine functions can be operated with just one double-acting control unit.
The Vendro T is equipped with an oscillating two-point hitch which enables the machine to follow any ground contour and ensure ideal ground tracking.
The Vendro T running gear which also carries the lights folds up and sits atop the rotors during work. With the running in this position, Vendro achievs a uniform distribution of the load which in turn translates into a uniform spread across the full work width.
The entire folding process is carried out quickly and sequence-controlled via a double-acting spool. This cuts out the risk of operator error and minimises folding times. The use of check valves ensures that the booms won’t lower or raise erroneously and eliminate the need to operate a cable.
The transport chassis, which folds a long way down, gives the two lower rotors sufficient ground clearance during transport to prevent them from coming into contact with the ground, even uneven ground.
- Working widths of 11.20 m and 13.40 m with 10 and 12 rotors
- Low-maintenance drive train for maximum reliability
- Hydraulic axle relief for optimum forage quality and sward protection
- Optional hydraulic working height adjustment for convenient flexibility in varying conditions
The trailed models in the Vendro series not only
impress with their unique technology, such as
the OptiTurn rotor concept which ensures optimum
forage quality, but also with their extremely
robust design which offers maximum
reliability. Thanks to their special design and
the many technical features, the machines are
also extremely easy to drive and operate.
If the deflector curtain for limiting edge spreading and/or the hydraulic working height setting option are used, the corresponding hydraulic functions are preselected via an electric operation box. This allows the machine's range of functions to be expanded without increasing the tractor's requirements in terms of the required control units.
The Vendro C models feature mechanical working height adjustment as standard. A crank handle can be used to centrally adjust the working height of the tines for the entire working width. This way, you can easily adjust the height to varying conditions. The optional hydraulic working height adjustment can be used to adjust this setting conveniently from the cabin at any time.
In the working position, the transport axle is hydraulically relieved, thereby distributing the weight between the rotor wheels and the hitch. This prevents the transport wheels from rubbing on the sward when cornering tightly, while retaining their function as "guide wheels".
The C models are hitched via a reversible drawbar for top and bottom hitching and a drawbar eye (40 mm). On request, the drawbar can be fitted with a ball-head hitch 80 or a swinging drawbar for bottom hitching. The Plus models have a two-point headstock. To ensure optimum load equalisation, the two-point headstock is equipped with a tension spring which effectively prevents negative drawbar loads. This enables small and light tractors to be used safely.
The Vendro C models are equipped with a double-acting and a single-acting control unit as standard. The double-acting control unit is used to fold the machine sequentially from the transport position to the headland position and back again. The single-acting control unit is used to lower the rotor outrigger from the headland position to the working position and lift it back to the headland position. This means that the machine can be folded out of the cabin very conveniently and operating errors are ruled out.
