39-53m³ Zelon CFS Forage Wagon


Zelon CFS - CFS efficiency from 39 m³

The Zelon now offers the Continuous Flow System (CFS) from a loading capacity of 39 m3. Given the increased fuel costs, the Zelon forage wagon is able to gain the significant benefit compared to other harvesting methods. The CFS unit enables you to load more tonnage per m3 - with less time and lower running costs.

 Zelon CFS Forage Wagon

This entry-level forage wagon is perfect for dairy farms with their own machinery or machinery cooperatives.

● Loading capacity, medium compression 39.1 - 52.7 m³ ● CFS accelerator drum ● Helical rotor ● 32-knife double sided knives ● Power required from 70/95 kW/HP


Continuous-Flow System (CFS)


Continous-Flow System (CFS)

Due to the interaction of the different components, the CFS unit ensures excellent loading performance and a low power requirement. The pick-up, CFS roller, rotor and double-cut cutting unit are optimally matched to each other. This results in an excellent cutting quality and power efficient drive, saving time and money.

Low power requirement

The newly developed pick-up and the "CFS drum" spreads out and disperses the swathe and feeds it over the entire width of the rotor and the cutting unit. The rotor, which is mounted 100mm higher, conveys the pre-wilted green fodder through the shortened conveyor duct into the cargo space, thus saving energy and reducing the power requirement by approx. 10%.

Full width filling

Thanks to the CFS roller spreading the forage over the whole rotor width, the material is loaded into the cargo space over its entire loading space. We measured 10% more weight per cubic meter. The CFS gives more weight than the competitors at the same capacity, making the tonnage capacity more important than the cargo space volume.

High Performance

A better filling spread also affects acreage performance. The areas to be harvested can be cleared quicker and the fodder is moved faster to the clamp. After all, time is money.

Optimum Adaptation to ground contours

Due to the design of the CFS drum, the pick-up is at a very shallow angle, such that the pressure exerted on the feed rollers is very low, which enables the pick-up to better adapt to the contours of the ground.

Furthermore, the green fodder is continuously and gently picked up due to the V-shaped helical arrangement of the pick-up tines. 

Tines are always picking up, but the V-shape means not all tines are touching the ground at the same time, preventing power peaks.

Protection of drives

Due to the homogeneous and continuous flow of material, the CFS conveying unit runs very smoothly and consistently, meaning there are hardly any peak loads. And if there are no peak loads, the complete drive unit will be free from excessive forces ensuring a long service life of the conveying unit and therefore of the entire forage wagon.

Longer service life of knives

As the "CFS" system spreads the grass evenly across the chopping rotor there is an even load on each of the knives. This means that knives wear more consistently and the sharpening interval is extended. On machines without a CFS system the central knives become blunt and reduce machine performance, this does not happen with a Strautmann "CFS" pickup. In addition, the knives are designed so that you are able to sharpen or replace only the blades that you need to, rather than all of the knives.

Conveying Unit CFS Conveying Unit

Conventional conveying unit:

The picked-up green fodder is delivered to the rotor without spreading-out effect. The rotor and the cutting unit are partially loaded.

CFS conveying unit:

The picked-up green fodder is dispersed by the pick-up and the accelerator drum and fed to the rotor and cutting unit over the entire width.

CFS Feed rotor

● Robust conveyor drum with helically arranged conveyor fins with Hardox tine plates ● Smooth operation, with no peak loads due to the helical rotor design ● One-sided, torsion-free drive of loading rotor due to low-maintenance gearbox ● Wide strippers with Hardox plates.

CFS Drum

Distributor drum between the pick-up and rotor. ● Delivers fodder from pick-up to the rotor ensuring low hp requirement ● Even, full-width spread of material due to the helical welded layer, so the entire rotor width is utilised, keeping a minimal and constant load on the machine. 

CFS Drum

CFS Cam-less pick-up

● Picking-up width of 1.70 m ● 5 tine rows placed in a V-shape for smooth and even material flow ● Cam-less pick-up with very few wearing parts and low maintenance, compared to traditional Cam pick-up systems ● Plastic strippers for minimum tine wear.

● Tandem axle assembly ● Spring-loaded tandem axle (40km/h) for optimum driving characteristics and easy towing ● Optional: Tandem steering where the rear axle freely follows the movement of the tractor and wagon. Active steering axle that utilises a second ball-joint on the drawbar which activates the rear axle as the tractor and wagon turns, helping prevent excessive tyre wear.

Electro-hydraulic easy-to-use control. The hydraulic valves are controlled via a control-box which is easy to operate and is mounted next to the tractor driver. Control lights for all vital functions ensure safe operation.

ISOBUS control

The optional ISOBUS control offers the driver easy operation without having to familiarise themselves with a new control box. Of course, the ISO suitability also creates the option of operation via existing terminals on the premises or on the tractor. Thus, interesting advantages of the valuable control terminals can be transferred to the machine use.

Central lubrication system

● Centralised grease lubrication system for all lubrication points on the vehicle.

32 knife cutting unit

● Easy cutting cut due to optimum geometry between the cutting knives and rotor ● Knife protection without use of tools ● Turn-able knives due to double-sided blade for longer sharpening intervals and better cutting quality ● Individual knife protection with knife quick-change system ● 32 knives, on one level for a cutting length of 44 mm ● In case of shortened knives, readjustment of the entire knife bar via upper link ● Hydraulic extending and retracting of the entire knife bar.

Strautmann knife protection - in-work Strautmann knife protection - safety break-back

Instead of the knife being pressured into the rotor, the knife is set up with a cam clutch tyre system. The spot-on triggering, without the spring counter tension, means a foreign object will trigger the knife to roll out of the work position, thus only blunting or damaging one point on the blade. A conventional knife protection will cause the foreign object to travel the entire length of the blade before releasing it, blunting or braking a large portion of the blade.

Transport floor

● Divided transport floor with 4 transport floor chains ● Hydraulic transport floor drive with two 10 mm high-strength chains and handy U-shaped steel sections ● Breaking load of 13 t per chain ● Automatic transport floor chain tightening ● Optional 2-stage feed motor ● Standard bumper buffer

A move to DIY silage-making using a forage wagon has helped one organic Somerset dairy get milk from forage up over the 5000-litre mark.

Proving that point, Somerset producers Rachel and Joe Horler have this year breached the 5000-litre barrier for milk from forage, taking the average yield from their 85 Holstein Friesian, Jersey and cross-bred cows to 7800-litres/year.

“We’re on a liquid organic contract with Coombe Farm and so our main driver has to be volume, but to do that we have to concentrate very hard on making sure our cows are as well fed as possible,” explains Mrs Horler.
