RADIUM 245 & 250

The KAWECO RADIUM silage wagons are a proven concept. Over the years, over 2.100 silage wagons have been produced by KAWECO, which all found their way alongside forage harvesters across the globe. Their extremely sturdy and stable build, based on its origin as a corn silage wagon, makes the RADIUM wagons unique.

The RADIUM silage wagons are available in 4 types:

  • 2-axle RADIUM 245, 250 and 255 series
  • 3-axle RADIUM 260 series

The RADIUM was updated to the 2.0 version in 2019. The most important changes are the design, the total height below 4 meters including R30.5 tires, and the faster unloading.

Let yourself be surprised by the high unloading speed!


The RADIUM 245 and 250 all come with a boogie-suspended undercarriage, with a trailing-steered rear axle. As an option, hydraulic steering and suspension can be provided. The boogie suspension ensures that high peak loads are compensated for and that these are not passed on to the chassis and the superstructure. Even on the grass of corn silages the undercarriage provides great stability of the wagon. The steered axles ensure as little damage as possible to soil texture, and tire wear is significantly reduced as well. The drawbar of the RADIUM 245 and 250 comes with a suspension of plastic bellows; as an option, the wagon can be equipped with hydraulic drawbar suspension.

The undercarriage consists of two stable and sturdy UNP-beams onto which all the essential components are welded. This construction method guarantees maximum strength during the severe conditions of the harvest. By means of twist locks, the superstructure can easily be attached to the undercarriage, and torque is hardly transferred from the chassis to the superstructure.

The superstructure

The RADIUM was the first silage wagon with a conical superstructure: the rear is 5 cm wider than the front. This guarantees a good unloading process, no matter which silage product has to be unloaded. The conveyor floor is galvanized for the longest possible lifespan.

Front wall

The front wall of the silage has been made from a grid plate, so that driver has a perfect view of the loading process of the wagon. The top part of the front wall can be lowered hydraulically, which makes the loading easier during the mowing of a new corn field. An alternative solution for the fast and easy mowing of a new corn field is the tipping RADIUM series; this version makes it easy to follow the forage harvester backwards.


The tailgate has mechanical transport protection to ensure safe transport. Hydraulic cylinders first lift the tailgate vertically so that it is released, after which it can be opened. The new RADIUM has a completely closed tailgate to make sure no silage is lost along the way.

Conveyor chains

All RADIUM silage wagons are equipped with 4 strong and durable chains that are driven by a double gearbox. The heavy chains and double drive make for easy, fast and reliable unloading. The no-maintenance conveyor chain is placed between the chassis and the superstructure, so that it is protected optimally. The new RADIUM 2.0 unloads considerably faster than its predecessor, so it was decided to work with a different type of chain.

Wagons without silage beaters have a hydraulic drive, wagons with silage beaters are equipped with a mechanical drive. The silage beaters are also mechanically driven and they are linked through a chain transmission. Automatic chain tensioners ensure the perfect chain tension at all times.

Silage beaters

The RADIUM silage wagons can also be fitted with silage beaters, which ensure an equal distribution of the silage product over your silo. Thanks to the equal distribution over the complete length of your silo, you will need less time to level the silo with the wheel loader/tractor. This results in a higher silage quality and a higher capacity of your harvesting team.

Driven axles

Thanks to the very stable construction method of the undercarriage your RADIUM can be equipped with driven axles. In the most extreme cases up to 9,000 additional tractive power can be transferred to the chassis.

The axles are driven mechanically; this mechanical drive provides traction in any situation and the wagon will continue to run as long as the tractor delivers power. It is also easy to realize a longitudinal or transverse press. To guarantee the safety of the system and the driver KAWECO uses a engageable clutch. This ensures that in every situation the drive train can be disconnected.

A big advantage is the lower fuel consumption due to a more even distribution of the power in both the tougher conditions in the field and on the silage. No extra tow tractor is needed when the conditions in the field become heavier or the silos higher. Unloading at the silo at all times so there is no need to push silage against the silo and more time is left for dividing and locking the silos.


Mechanical transmission instead of hydraulic transmission on P-trailers. (Standard on S-trailers).


Cover to prevent falling loads. This cover folds to both sides of the trailer.

Side marker lights LED mounted on the side (3 pieces).

Raising the superstructure of the silage wagon makes it easier to start in a new field when driving backwards.


In addition, the bottom chain is relieved more during the unloading process.
