If cows could choose

Then they opt for optimum quality of roughage. A healthy cow gives stable milk production!

The quality of the roughage depends on the method of covering. It is all about good preservation, so a good covering system is essential in addition to the silo elements. This silo cover system ensures a fast, efficient and almost air and watertight seal of the roughage.

The silo cover system consists of a specially designed silo cover and a silo cover machine. Water trunks (105 kg / m1) have been applied along the entire length of the trench silo cover, these trunks are filled with (salt) water. This makes the rug tight, almost vacuum stretched over your roughage. The loss of roughage is thus limited to a minimum because almost no air and (rain) water can get between the rug and your roughage.

12 years of experience show that the elastic heavy cover ensures that the preservation of your roughage runs optimally. The cover has a weight of 1.7 kg./m2, is resistant to crows and provides an effective and fast airtight seal with an optimal water drainage.

This preserves the grass in a much shorter time, partly because many more sugars are left behind in the roughage and the less forcing becomes sensitive.

With this system, the conditions of the roughage remain optimal and it facilitates the way in which the cow stays in and out, keeping the cow healthy and giving a stable milk quality.

Convenience serves people

By using the machine in combination with the hydraulics of your telehandler or tractor with front loader, the rug can be rolled quickly and easily over the pit. This is all you have to do!

Less labor intensive – hydraulically mobile

The cover system is also hydraulically movable over the silo walls. This works quickly and efficiently.

The design of the silo cover is geared to improving the quality of the roughage, saving labor and the user-friendliness for the farmer. The expected service life of the cover is 10 to 15 years. The oldest covers are in the 12th season.

The advantages of the bunker covering system

By properly covering the roughage you get a considerably better quality feed for the cows and it works more efficiently.

Kornet offers a silo covering system with a elastic cover with a weight of 1.7 kg./m2 that is also resistant to crows. With an effective airtight seal and optimum drainage of rainwater and press juices, this rug improves the quality of the roughage.

  • Less labor intensive, no dragging with sandbags and tires
  • Reduction of labor costs; easy to use system saves time
  • Improved quality of the roughage, thanks to a practically air and watertight cover seal
  • The system fits on different types and widths of the silage bunker
  • Can be used on multiple and adjacent silage bunkers
  • Cover system falls under strict Danish regulations and environmental investment subsidy scheme
  • No more (black) silage plastic and (bird) protective tarpaulin needed
  • Almost no nuisance from vermin, due to a tight cover
  • Hydraulic system, no electrical power supply required
  • Virtually no rainwater in the hump, therefore almost no flush of silage juices
  • Optimal preservation process, due to gray color and the weight of the rug
  • Less strict requirements on silo bunker height thanks to stretchable cover
  • Now with an interchangeable role that can also be changed during interim ensilaging in the summer

Interim ensilaging

Because the tubular water pouches (± 105 kg. Per linear meter) presses like a wedge between the roughage and the bunker silage wall, a perfect seal is obtained. The heavy water tubes pull the elastic cover down, as it were, so that the cover fits tightly over your roughage like an elastic. The cover is crow-resistant and has the same properties as shrink-wrap.

You can easily pull the elastic cover off the roughage product in one go with the hydraulically driven machine. This is made possible by the fact that there are reinforced ribbons in the cover in the longitudinal direction. As a result, the cover cannot be pulled broken or porous.

When the cover has been removed, with interim silage, the sweet smell of the product meets you.

Even when the farmer opens the grass silage for the next layer of product, this is easy and fully automatic. The system runs perfectly straight onto the roll due to a fixed reference on the silage wall.

Cover roughage with the silage cover system

Covering your roughage is easy and fast! After ensiling and the ensilage is stuck in the bunker, it does not take much time to cover the ensilage bunker. You do not need any help from others to cover it, only a tractor with front loader, shovel or telehandler is required. Or possibly to move completely hydraulically!

Connect the covering machine to this and operate the machine via the hydraulics. From the back you roll the rug over the bump.

As soon as the carpet has been unrolled, you link the water tubes to the KCS filling system and the overflow system. The water tubes of the cover can now be filled. Filling the tubular water pouches is easy with the help of the supplied Kornet Cover Solutions filling system. With a bunker 40 by 10 wide, the water pouches are filled in about 40 minutes. You do not have to stay constant with this, it is protected with an overflow system. Only check regularly if everything is going well. If they are filled, disconnect the system.

Thanks to our extensive experience and knowledge, we can optimize the portal system for you so that it leads to a higher return.

Feeding with the silage bunker covering system

The extraction of the silage is easy and fast. You do not have to remove tires and gravel trunks first and uncover the silage bunker. Simply place the covering machine on the selected silage bunker, at the start of feeding. The next time you start feeding, all you have to do is connect the covering machine to your tractor with front loader, shovel or telehandler. The machine rolls up the desired number of meters of the cover, you decide how much roughage will be released. Then you disconnect the machine. All this takes just a few minutes. The covering machine remains on the silage bunker as long as you continue to extract feed from the bunker.

The cover system is particularly easy with severe weather conditions such as snow or wind. With the covering system you can still roll the cover easily in spite of the snow, as was evident in the winter of 2009/2010. This way you are always sure that you can feed.

Because the machine with the roll and the cover remain above the roughage, you work as it were behind a “screen”. As a result, your exposed roughage remains considerably drier, which offers you advantages if you feed by weight.

An overflow system at height ensures in all cases a good and even filling of the pouches. As a result, the water pouches always remain well filled with the correct amount of (salt) water.

Specific information about the KCS covering system

The covering system is supplied complete, including:

  • Covering machine
