But if the farm has a lot of chickens and grind the grass every day, it takes a lot of time and is pretty boring. You can fix the situation and make a grass chopper for the hens yourself. Its design is simple. To begin with, four legs from the old stool are connected in pairs. They put a tray of boards eighty centimeters long. And the front knives are fifty centimeters taller. In them grooves are cut, which end below the tray bottom. The groove has a width that allows the blade of the braid to move freely, to the blunt end of which the handle is welded.
The point of the braid is attached to the foot pedal by means of a system of levers. There is a grass chopper for chickens on this principle: with one hand the homemade knife is pulled up. Vegetable mass with the other hand is pushed to the cutter, and the foot presses on the pedal. Grinded grass begins to pour into the container, which was previously set for this purpose.

To make the structure stand, you need to attach the legs to the bottom. As an upper container, you can use an old saucepan. To do this, a hole should be cut from the side and it should be paneled with sheet metal. Through it will come out the processed material.
From the lengths of the saw, knives are made and fixed on a bush fifty centimeters high. You can make it yourself or order it to a specialist. A hold the entire structure will be a rack of durable material, for example, the legs of the stool. For fastening works, water nuts are best suited.
Further work with the engine. It is removed from the pulley. He is no longer useful in the work. The motor is fixed to the casing with clamps, which are at the same time and tightening the design. The inner diameter of the hole at the top of the cylinder must be the same as the diameter of the shaft in the engine. Fixing drilled two holes with a diameter of eight millimeters. They are coated with thread M8, to which are fastened the bolts. Before the pinned sleeve on all sides of the shaft, made a small indentation. For output of processed raw material under the knives of the hole. If it is not possible to make a hole at the bottom of the top container, it must be cut on the side.
