Greetings to all who like to craft, I propose to consider homemade, which will allow to clean up your site. It's about a small lawn mower with an interesting design. The homemade product is assembled on the basis of an old burned out grinder, thanks to which we turn low revolutions of the drill into high revolutions of the mowing knife. The assembly of the homemade product is quite simple and does not require special equipment and skills. The mower mows perfectly, and the drill drives the action. If you are interested in the project, I propose to study it in more detail!
Materials and tools used by the author:
Material List:
- a burned out Bulgarian (a reducer with a rotor);
- drill (as a motor);
- sheet steel and plates;
- bolts and nuts;
- wheels from an old trolley;
- iron rods;
- wire, plastic ties.
Tool List:
- lathe (optional);
- welding machine;
- grinder;
- roulette;
- marker;
- drill and crowns;
- a vise.
Homemade manufacturing process:
Step one. Grinder preparation
We take the old burned out grinder and disassemble, we need a gearbox with an anchor. This gearbox reduces the speed, but if you rotate it behind the outgoing shaft, the speed will increase on the rotor, and the lawnmower needs precisely high speeds, which the drill can’t give out. Among other things, a right angle is advantageous in that everything can be conveniently fixed.
We need to grind the shaft of the grinder so that it can cling to the drill chuck. The author used a lathe to solve the problem, but there are other ways. For example, you can rotate the anchor with a drill and grind the shaft with a grinder, the result will be no worse. And you can put an elongated nut and wrap a threaded rod turned to the desired diameter in it.
Step Two Frame
We assemble the frame for the grinder instead of the body, here we need plates and sheet steel. Note that the rotor will be a knife, so keep all the necessary distances for installing the blades.
We need to drill a hole in the steel plate for the armature bearing, we use a drill bit of suitable diameter. We fix the gear part to the frame with bolts and nuts.
Step Three Knives
We need a steel plate, cut it into pieces of suitable length and bend in the form of the letter "G". We sharpen the manufactured knives with a grinder and now we need to weld them at right angles to the rotor. We weld the knives so that they overlap each other.Of course, for knives you need to use good steel and harden it, then the blades will not be blunt for a long time.
Step Four Wheels
The wheels must be installed on the lawn mower; the author used wheels from an old baby carriage. To install the wheels on the frame, we bend from the bar parts in the form of the letter "G" and weld them to the frame.
Step Five Further assembly
At the end, we weld a simple design for attaching the drill, the author fixed the drill with wire, and the switch was pulled in the on state with a plastic screed.
We also make a protective shield over the knife from the steel plate so that a stone or a stick does not fly into the face. We also weld a handle from a piece of iron pipe.
The homemade product is almost ready, we install a socket with a switch on the handle and can be tested. The mower is ready, mows homemade without problems, the product is more like a small combine. The machine speed can be adjusted with a drill, and if the drill is a battery, homemade turns out and is still independent of the network.
This is the end of the project, I hope you liked the homemade work, and you found useful thoughts for yourself. Good luck and creative inspiration, if you decide to repeat this, do not forget to share your ideas and homemade things with us!
