Straw cutter with knives from a circular saw blade

In every household plot after harvesting, the question arises of where to put on the tops, weeds and other wastes of country livelihoods. First to first, it will be an excellent compost, but if you put all this in its entirety, the process of decay will last a long time. And now, many gardeners are adopting all kinds of choppers. A thing is very useful but, accordingly, costs money, like any thing in our world. How to be a simple person, it is natural to assemble a similar unit do it yourself from improvised means.

So our author has long dreamed of such an installation in order to grind the tops and straw, as he wants to engage in the cultivation of oyster mushrooms, and for this we need a straw chopper. For the substrate, it is best to use chopped straw - this increases the productivity of mushroom growth.

What did the author need?

Materials: circular saw blade, metal 4 mm, electric motor 220 V, bolts, nuts, screws, copper wires.
Instruments: welding machine, grinder, drill, set of keys, screwdriver, wire cutters, hammer

First of all, the author sawed all the metal in size.

The main element is knives, the author makes them from a circular saw blade

Everything is sawn very evenly, as the knives must be the same even in weight to avoid vibration.

These are the calibrated knives

Subsequently, the frame and the drum were welded.

Then the author mounted the knives on a rotating disc

The last one was a bunker for loading straw or tops.

The engine is installed. So the straw chopper is such an irreplaceable thing in a summer house.
