Every farmer who owns at least a small barnyard, there is a need to prepare fresh food, which the young and adult animals are more likely to eat.
It is for this and there shredders to create small fraction feed.
Use of the unit in agriculture
On all large farms there are choppers for grass, straw, twigs to prepare feed mixtures for chickens, rabbits and other animals. Often these units are very powerful and are designed to work with large volumes of feed. For small farms, where the livestock of animals is small, the use of such machines will not be justified. Undoubtedly, many companies are engaged in the production of small-sized small-sized grinders, but often their price is too high for the average consumer, and this has led many people to collect grass grinders with their own hands.

How to make a garden shredder
Hand crusher, hand-made, has many advantages. Its production is much cheaper than buying factory, because the necessary parts and parts can be found on hand. Such a device can be collected for the preparation of any specific feed. And then we look at several types of homemade shredders. 
The easiest way: use a drill
The design of the combine with the use of a drill as close as possible to the design of a conventional kitchen blender. You will need a drill with a power of at least 620 W, preferably a metal bucket (for grass) and a shaft with a knife. The basis of the design of such a shredder is a rod whose length is from 30 to 40 cm, and the diameter - from 10 to 12 mm, at the end of the rod there should be a thread of about 40 mm for fastening the blade (knife) between several nuts. The knife can be made from an old hacksaw blade, sharpening can be either one-sided or two-sided, or you can purchase a knife for a motor braid.
Did you know? You can build a structure for fixing the bucket - this will facilitate the grinding process.
From vacuum cleaner
The operation of such a mechanism resembles the principle of operation. food processor. Its advantage is high productivity and stationarity. It is also envisaged that the milled product will exit from the hole located at the bottom into the pre-filled bucket. 
For this unit, you need a vacuum cleaner, or rather its body: the most appropriate will be the old Soviet vacuum cleaner "Typhoon", but for lack of one you can adapt another one. You also need an electric motor of 180 W and more: it can be removed from an old washing machine. Blades, as in the past case, can be made from unnecessary hacksaw blade. A threaded sleeve for fastening knives with nuts must be cut out on the machine, its length is 40 mm.
In advance it is necessary in the tub, which we made of the vacuum cleaner body, to cut a hole for a cube-shaped platform on which it will stand. The engine is attached to the bottom of the tub, and then the knives are fixed with the help of 32 mm nuts. The opening for grinding should be 7 cm by 7 cm in size and located under the knives or on the side below.
Important! For greater stability, the tub must be welded to the frame.
From washing machine
The grinder from the washing machine is completely identical to that which is made from the vacuum cleaner - the only difference is its size. Here, the body of the washing machine is used as a container (as you prefer), and the sleeve should be at least 5 cm long. 
Important! In order not to overload the engine, do not lay too much grass.
Tips and tricks for making
For a container where the grass will be loaded, in principle, any metal cylindrical vessel of large volume can fit, even a large pan can descend. As already mentioned, as a knife, you can use regular wood saws, which have become unusable, but, based on reviews from various forums, the best option would be home-made knives from a band sawmill. And to reduce vibration during operation, two knives can be placed crosswise.
Did you know? In order that the device could grind branches, use the petrol engine.
Each of the above shredders has sharp blades, and they are also equipped with electric motors. And in order to work with these devices facilitated your housekeeping, and not caused injury, should observe the rules of safe behavior with cutting objects and electrical appliances, and most importantly - Protect the cutter from children.
The best grass for chickens is grasses of legumes and grain crops: alfalfa, peas, wheat and oats, as well as meadow grasses: dandelions, purslane and nettle.
