In small summer cottages, mowing - cutting grass - ants are often brought in places where, as they say, you should not meddle with a hand-held or any other mower.
For example, when treating a plot densely planted with cultivated trees, shrubs or flower beds.
Rescue structures made do it yourselfin which the working bodies are knives - cutters rotating with large revolutions in horizontal planes.
The simplicity and reliability of such structures is time-tested and adequately appreciated by fans to do everything with their own hands, and by specialists who already use rotary braids.
I hope that no less interest will appear in the published design.
Your attention is invited to a small home-made electric mower for work in areas with uncomfortable terrain or narrow approaches.
In a small area where there are no networks with a voltage of 220 V. And the design of the mower is such that it is available for DIY production even by a novice.
The “rotor-mowing” arrangement without “bells and whistles”: an electric motor with a cutting working knife — a cutter at the end of the shaft — is screwed to the base.
The required grass cut height, safety cover for touching the ground with a knife and easy movement of the electric braid are provided by skids adjustable in height.
And now about the features of the self-made "rotor - mowing". The base is cut from a piece of 3 mm sheet duralumin, not only is the electric drive mounted with a knife - cutter, but it is also an active part of the cutting apparatus. Due to the radial configuration, the base forms sheaves of grass, feeds them under a knife - cutter with the subsequent ejection of mowed grass to the side.
In contrast to the “store” lawn mower, the mowed grass here is not crushed several times, which significantly reduces the load on the knife and electric motor, but moves in a directed flow.
Grass is removed at the very base. But you can also mow it from the tops, gradually lowering the base of the electric braid to the roots. This is done when they want to chop the grass.
The stiffness of fixing the knife on the axis of the electric motor is achieved with two clamping washers and two nuts with engraving washers and careful balancing of the knife-cutter. The imbalance is eliminated by simply removing the excess mass of metal on the knife on the grinding wheel.
The engine in the "rotor - mowing" - 12 volts, 40 watts, which runs on a car battery
or on-board car network.
