Zelon – exceptionally low resistance and small cut size

Compact dimensions, low power requirements and a continuous mass flow system are the main features Zelon advantages. As a result Loading is fast, feed is protected and fuel consumption is reduced.

This forage trailer Perfect for independent dairy farms or fleets that value high feed quality and low power consumption.

This is a great first step into silage trailer technology, starting with a loading capacity of just 24 m³. This self-loading trailer enables even smaller farms to benefit from the benefits of a powerful silage trailer for processing green fodder using their own machinery. Whether it is daily feeding of fresh grass or silage - This trailer ensures optimal work results and impressive performance.

STRAUTMANN Zelon: What Sets These Collection Trailers Apart

A steady flow of feed and lower fuel consumption

The Continuous Flow System (CFS) ensures a smooth flow of forage from the pick-up to the rotor. Thanks to the optimal coordination of all components, power requirements are reduced, the trailer is easier to tow, and fuel is saved.

39 mm cut for high-quality feed

37 double-edged Exact-Cut blades ensure a precise 39 mm cut. The blades are easy to flip and can be changed without tools, while the automatic safety system helps maintain consistent cutting quality and reduces downtime.

Cleaner feed and less wear and tear

The innovative Flex-Load pick-up with plastic tines adapts precisely to the terrain, reduces contamination of the feed with soil and stones, and features extremely low wear. A broken tine can be replaced in less than a minute.

High power output starting at 95 AG

Their compact design, low power requirements, and models with capacities ranging from 24 to 35 m³ allow them to operate efficiently even with lower-horsepower tractors. This makes them an excellent choice for dairy farms and farms that prepare their own feed using their own equipment.

Efficient loading with the Continuous Flow System CFS

Due to the smooth operation of various components continuous flow system CFS ensures excellent picking performance, requiring minimal power. The collector, flow roller, rotor and Exact-Cut cutting system are perfectly matched and complement each other.

The result is not only excellent chopping quality, but alsoengvas trailer towing, allowing you to save power, time and money.

1. Cutting system and rotor:

Precise grinding for perfect compatibility.
The finger plates welded to the rotor ensure a smooth and precise cut.
The small distance between the rotor fingers and the blades ensures extremely precise shredding with minimal power consumption.

2. Pick-up: gentle grass collection and even swath distribution

A simple, lever-less mechanism.
Plastic dividers.
1.8 m working width.
Six rows of tines arranged in a V-shape distribute the grass evenly.
To accommodate the additional flow, the reel is positioned very flat—allowing it to adapt perfectly to the ground surface.

3. Optimal filling across the entire width:

Reduced power requirements due to the rotor mounted higher up and the shortened transport channel.
The material is fed into the cargo area across its entire width.
Maximum and uniform compaction means more weight per cubic meter.

4. Flow roller: spreading material and fast filling

Faster charging with lower power consumption
The flow roller distributes the feed material through a special, welded layer
The material is evenly transferred to the rotor across the entire working width
Material acceleration ensures a continuous, uniform flow
Always uniform material supply from the gripper to the rotor
Feed does not accumulate or get stuck

Flexible loading – saves time and energy

The Flex-Load pick-up is designed based on Strautmann’s many years of experience. Its innovative plastic tines ensure exceptional wear resistance, adapt precisely to the terrain, and cleanly collect feed from the swath. Reduced wear leads to lower maintenance and operating costs.
