Working principle of pre-cutting system

Special knives are used to cut plants that will be packed in a bale net wrap, twine or stretch film with a baler. They are fixed on the rotor, which is located behind the baler. In this way, the feed stuff passes through this pre-cutting system before entering the bale chamber.

Benefits of pre-cut feed stuff packaging

Due to the fact that the length of the plants becomes shorter after cutting, they can be packed more tightly. That is, after pressing, each bale becomes heavier and fuller. This makes them more stable in terms of their shape and at the same time heavier.

The more feed stuff is pre-cut into a bale, the heavier, denser and more dimensionally stable it is. Thus, such bales will remain without deformation even when stored on top of each other. But it is this type of storage that allows them to take up less space.

1. The more feed stuff can be packed in one bale wrap net, the less packaging material will be spent on the same initial amount of workpiece. And although the pre-cutting system slightly increases gasoline consumption, it reduces the consumption of packaging material. This speeds up and simplifies the work of the baler operator and the farmer in the future.
2. The advantages of heavy bale nets over standard ones are also at the stage of transportation. In this way, it is possible to transport more kilograms of feed stuff at a time: a bale net wrap takes up as much space as a regular bale net, but contains more feed inside. This is also an advantage at the feeding stage, as the farmer gets more feed stuff by opening such a bale wrap net.
3. If it is a net wrap for sale, then it will also be more profitable and interesting for buyers to purchase more filled ones. Since in this case they can significantly save on transportation from the seller’s warehouse to their own farm, for example, by shipping once or twice instead of two or three.
4. If a farmer prepares a feed mixture for his animals instead of feeding a single product directly from the bale net, then it is easier to use pre-ground feed stuff. Bales after pre-cutting are easier to break into pieces that are easy to work with mixers. The result is a more evenly mixed feed stuff.
5. Another unexpected and non-obvious, but important benefit of using pre-ground feed stuff: there is less waste due to falling out of the feeding bunk. After all, if, for example, a cow begins to chew hay, then those parts that will be behind the mouth fall to the ground. After that, the animal no longer eats it. Accordingly, part of the feed stuff simply becomes waste. On a diet pre-cut into 4-6 inches of food, the animal consumes a significant portion of it. That is, the efficiency of feeding increases.
6. Animals also prefer foods that are shorter in length, as they are easier and faster to chew. At the same time, the efficiency of feed stuff consumption increases. Some farmers have already noted an increase in animal weight and productivity of about 10% after switching to a diet with pre-ground hay. 10% increase in profits from beef cattle is a pleasant increase in a farmer’s income.

Summary

Balers with pre-ground systems are more expensive than conventional balers, but they save on packaging materials. Investing in this equipment brings significant benefits to the farmer through increased forage efficiency and other additional benefits that are possible from higher bale density and shorter forage length.
