Larger forager harvesters, Shredlage chippings and larger distances call for larger silage wagons. KAWECO’s solution: the RADIUM 255 and 260. With its 47m3-content the KAWECO RADIUM 255 is one of the largest wagons in the market, offering all the crucial advantages of the RADIUM 245 & 250. 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 enormous volume of a RADIUM 255 places a considerable burden on the undercarriage. To manage this, the RADIUM 255 is equipped with hydraulic axle suspension and hydraulic forced steering. The hydraulic axle suspension is fitted with a load-dependent two-chamber nitrogen suspension system. This suspension provides an optimum balance between load, suspension and speed, which creates ideal driving properties. The broad axle base, which is standard, allows for mounting the tires up to a height of 1500 mm (R30,5) without exceeding 4 meters (Including cover system).


The new RADIUM 2 is equipped with a super narrow drawbar. This makes the new RADIUM easy to turn in all circumstances. The narrow drawbar is specially designed in order to protect the steering cylinder (Standard with hydraulic forced steering). The long design of the drawbar makes the wagon comfortable to drive with. Optionally the RADIUM can be equipped with hydraulic drawbar suspension.

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 life-span. By bolting on the side posts we create a very lightweight yet stable side wall which can be easily be renewed.

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.
