Smooth and precision-driven Vendro 820 - the key to even spreading and efficient drying!
This mounted tedder with 8 rotors and a 8.20 m working width provides maximum comfort for the operator, effectively accelerates the drying process, and delivers high-quality forage. It is perfectly suited for forage where achieving a higher dry matter content is desired or when there is a need to quickly dry wet forage before the next rain arrives.

Even drying and improved forage quality
As the harvesting window narrows, achieving optimal dry matter becomes challenging. KRONE's innovative OptiTurn rotors and 3D tines offer a unique solution with their three-dimensional shape, ensuring even and wide spreading that accelerates drying - improved water evaporation, increased air circulation, and superior forage quality. Reduce supplementary feeding, prevent feeding stress, and enhance animal health.
Adjust spreading angle to suit conditions
Whether it's silage in spring or hay in summer, different spreading angles are crucial for desired results. The Vendro hay tedder offers high processing for quick silage drying and gentle turning for hay. The angle is adjusted without tools - choose flat spreading (13° and 15°) for even hay distribution, or steep angles (17° and 19°) for optimal drying. The results are uniform drying and homogeneous distribution of dry material in your forage.
Timing is crucial in a narrow harvest window to save costs!
Being able to start tedding hay quickly when the weather allows is essential to avoid losses. With the Vendro, you're always prepared with minimal setup time, and maintenance is easy with just a few lubrication points. Krone's rotor gearbox also provides high reliability and stability, allowing you to work undisturbed during the forage season, save costs, and achieve high reliability.
Even drying with ground-following rotors
The OptiTurn rotor design is a crucial and specific feature of Krone's tedders. The unique design allows the rotors to generously overlap each other, and the OptiTurn tines can lift and evenly spread the crop with an optimal width for the best possible drying. The rotor arms are securely bolted to the rotors with an additional plate under the tine arm, providing a robust construction capable of handling large volumes of grass. Underneath each rotor, the rotor wheels with large tires are positioned extremely close to the rotor, ensuring optimal ground following without the risk of contaminants in the forage.
Smoother and more even spread with OptiTurn tines
The curved 3D tines with a thickness of 9.5 mm lift and toss the material to achieve clean and high-quality feed with even dry matter. The tines are attached with an eccentric plate allowing adjustment of the tine angle in three positions for optimal results in varying crops and terrain. To not miss any forage in the field, the tines are unevenly long in a pair, keeping them parallel above the ground, contributing to uniform wilting and optimal work quality in the new 3D tine system.
Reliable gearboxes for higher safety and longevity
The rotor gearboxes are mounted beneath the robust frame, where they are shielded from the strains of work and operation. They are both maintenance-free and lubricated with liquid grease, ensuring extended lifespan and trouble-free operations. Additionally, the gearboxes are independent of the frame, eliminating concerns about leaks, even in the toughest terrain.
Smooth and precise operation with damper braces
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. Also, they absorb shockloads and vibrations and take out sway when tedding in curved lines so that every single blade of grass is picked up and tedded into perfect forage.
Effortless angle adjustment for superior results
All Vendro models feature a hole system that allows you to easily adjust the spreading angle in four steps, ranging from 13° to 19°, without the need for any tools. A flat spread (13° and 15°) ensures even distribution and gentle hay turning, while steep angles (17° and 19°) provide optimal and more intense drying. This way, you can customize the machine's performance according to your specific preferences and keep the feed on the right side of the field edge to minimize losses.
Designed to assist with the drying process
The OptiTurn fingers generously overlap to lift the crop without contamination and distribute it evenly. With the right spreading angle, the optimal width for quick drying and good feed quality can be achieved. Close to the rotors, support wheels are positioned to ensure optimal ground contour following and prevent feed contamination. This technique enhances productivity not only in the field but also in the milking parlor.
Optimized reliability with OctoLink
The reliable OctoLink finger couplings are used in all Krone teddes. Each rotor is driven by a proven finger coupling with eight fingers, creating a strong and dependable connection within the driveline. Regardless of the angle, the power flow to the next rotor remains uninterrupted. The extremely robust finger couplings are completely lubrication-free, allowing you to save time on maintenance, increase productivity, and save money.
Maintenance-free and protected driveline saves fuel
OctoLink couplings ensure seamless operation without the risk of driveline damage due to operator errors. The coupling isn't damaged if the driver accidentally forgets to disengage it when folding the machine! With eight fingers creating couplings, the driveline to the rotors is never broken, ensuring uninterrupted power transmission. The OctoLink coupling allows for low power losses in the driveline, resulting in fuel-efficient use. Take advantage of a maintenance-free driveline that minimizes service and maintenance requirements while maximizing its lifespan.
Streamlined folding with double-acting mechanism
Experience the convenience of Vendron's hydraulic folding and unfolding of side sections between working and transport modes. Sequential control during the folding and unfolding of side sections eliminates the need for sensors and cable wiring. The side sections are secured in the folded position with hydraulic locking valves. Enjoy improved control of the folding and unfolding process, and increased efficiency!
Compatible with smaller tractors for higher flexibility
Experience the benefits of the shortened mounting concept, placing the headstock closer to the tractor. This minimizes front axle relief and ensures compact dimensions. The headstock features pendulum suspension, providing stability and ease of movement. Enjoy an effortless operation with little to no lifting power required.
Anti-wrap guards for smoother workflow (option)
KRONE tedders come equipped with anti-wrap guards as standard, preventing long-stem crops from getting caught around wheels and support legs. This minimizes unnecessary stops and ensures a smooth and efficient workflow. For enhanced effectiveness, the anti-wrap guards can be supplemented with additional plates, providing extra protection and uninterrupted operation.
