Effective Swadro S 420 - the key to an effective forage harvest!
This single-rotor rake has a working width of 4.20 m. It is designed with smart features that provide clean forage of maximum quality and makes the job easier for subsequent machinery. With its size and flexibility, it is ideal for slightly smaller fields, and it also requires minimal maintenance.

Let technology assist you in achievinng clean forage!
The Swadro is designed to ensure minimal waste and clean feed. A test conducted by DLG (Deutsche Landwirtschafts-Gesellschaft) showed that Krones Lift Tines reduce soil and gravel contamination in the feed, regardless of working speed, and minimize losses by up to 2.1% compared to other systems. Furthermore, it is lifted in and out of operation in a way that prevents the tines from hitting the ground, thus avoiding feed contamination or damage to the ground surface.
Timing is crucial in a narrow harvesting window to save money!
The aim is to consistently achieve maximum forage yield, even on small and medium-sized fields, but it requires the rake and tractor to be available at precisely the right time. Swadro S can be connected to various tractors, from large to small, to maximize flexibility and work when the timing is right.
Minimized downtime with field repairs!
If accidents occur, quick recovery is crucial as the value of forage diminishes with downtime. On the Swadro, a rotor arm can be swiftly replaced in the field without any oil spillage, saving time and money while also eliminating concerns about contaminated forage.
Reliable machines are the best friend of forage harvest!
Krone's Swadro models requires minimal maintenance due to its low-wear maintenance-free cam track and the hermetically sealed, lifetime lubricated main gear box. The combination reduces wear and upkeep costs, ensuring the rake is always field-ready. Only a daily visual inspection and lubrication of the power transmission shaft are needed, other maintenance is performed between harvests for a more efficient season. Farmers First Maintenance offers ready-made maintenance plans that contribute to reduced downtime, extended lifespan, and better resale value.
Clean forage and high work rates!
The robust Krone Lift Tines effortlessly lift heavy and wet crops off the ground. With a double bend design, they facilitate upward movement of forage along the tine. Compared to straight tines, they allow higher driving speeds without increasing losses or contamination. DLG (Deutsche Landwirtschafts-Gesellschaft), conducted a test showing that Krones Lift Tines reduce raw ash contamination in forage by less than 9% regardless of driving speed. They also minimize losses by up to 2.1% compared to other systems.
Change tine arm directly in the field
As most farmers have experienced, it is easy to bend a rotor arm when being in a hurry, and then, it's important to get back up and running quickly, as the value of the forage decreases with every hour of downtime. On the Swadro, a rotor arm can be quickly replaced in the field without any oil spillage because of the dry DuraMax cam track. It also has double ball bearings for stability, smooth control, and reduced wear. The durable tube is maintenance-free, securely connected to the control shaft for reliable and precise tine control.
Guaranteed function and reliability!
Maintenance-free and permanently lubricated and sealed gearbox make the Swadro a highly reliable partner in the harvest, regardless of the weather. This rotor rake is always ready for work and ensures reliable operation during the narrow harvesting window.

Protects the sward and produces clean forage!
Krones Jet Effect is inspired by an aircraft's takeoff and landing behavior in its rotor suspension design to ensure that there is always a maximum free space between the tine and the grass surface when the rotor is lowered and lifted out of operation. Without this margin, damage to the grass surface can occur, allowing weeds to grow, which in turn deteriorates the quality of the forage. However, with Swadro's design, these damages can be avoided, the tines last longer, and the result is clean forage.
Perfect swaths even in though terrain
The Swadro rake eliminates tailing, increases maneuverability, and ensures precise work with mechanical damper braces and a 20° steering angle. It effortlessly self-centers behind the tractor, handles sharp turns, and maintains stability in challenging field shapes. Achieve neat work and straight, boxy swaths for seamless integration with following machines.
Boxy and optimal swaths in all conditions
The Krone DuraMax cam track has a small diameter and steep track design made of special bainitic hardening that enables the tine arms to smoothly follow the curve and lift the tines out of work quickly and with ease. This innovative system ensures the formation of boxy and optimum swaths in all conditions, regardless of the terrain or crop density.
Effortless spring-assisted folding for seamless operation
On the entry-level machines, the curtain can be manually folded and extended to achieve the desired swathing width, with the assistance of a spring. This not only ensures quick setup but also activates a torsion resistance mechanism on the rotor, safeguarding it against operator errors. For added convenience, hydraulic curtain folding is available as an optional feature.
Can be used even with the smaller tractor and has low fuel consumption
The Swadro rake's rotor gearbox has a large gear ratio, ensuring low PTO speeds and minimal wear. This makes it compatible with small tractors, offering flexibility during harvest. The headstock has two positions for lower link attachment: a closer position for smaller tractors, reducing front axle load by up to 10%, and a longer position for bigger tractors with optimal maneuverability and large tires.
Achieve precise height control for optimal results
When it comes to height control, accuracy and reliability are paramount. That's why the Swadro rake is equipped with a manual crank that allows you to set the working height with millimeter precision, ensuring accurate ground contouring. With an easy-to-read scale, you can effortlessly adjust the rake to match the cutting height of your mower, eliminating guesswork minimize losses without contamination.
Tilt control for maximum efficiency
The lateral tilt control, set on the rear wheels, ensures minimal losses and the formation of boxy swaths. By tilting slightly towards the swath, the load on the tines is balanced, leaving no grass blade behind, even in heavy material. With an adjustable tilt using a pin/hole setting system.
