A lawn mower, today, is almost indispensable for those who have a cottage or a country house.
It doesn’t matter how often you drive out of town, but if you have your own house there with at least a small lawn, you will have to cut it one way or another. For these purposes, there is a lawn mower - an optimal device that combines all the necessary functionality.
It is mistakenly believed that a lawn mower is something well-established and having one specific model. In fact, this type of device has a huge number of variations: from mini cars to fairly large-sized lawn mowers. That is why, thinking about how to make this type of technical device yourself, you need to understand what you want to see in the end.
Where to begin?
You should definitely start by selecting all the details. Since you use a washing machine as the source, you will need:
- Wheels In this case, you can use the pram or trolley: borrow the details from them.
- Metal sheet. Be sure to observe the thickness when choosing: it should be 2 - 4 mm.
- Knives. Kitchen will not work, but from tool steel just right.
- Water pipe. It will serve as a hilt for your future lawn mower and that is why it must be thin.
- Power cable, respectively.
- Directly switch.
Let's go through the details
Returning to the theme of the engine. This is a very important part, so some factors must be observed.
Conventionally, you can focus on a 180 W engine with a start relay and, of course, a capacitor (suitable for the simplest and no longer needed washing machine, ideally if it is a washer of the old Soviet “origin”, since the inherent heaviness here will be just the way).
But the wheels can not only be taken from a pram or trolley, but also made with your own hands. In this case, you will need plywood and bearings directly. When installing, keep a distance of 5 - 6 cm from the ground. This segment is due to the height of mowing the grass. As for the number of wheels, it all depends on the model you will be making.
For example, 4 wheels is the most optimal option, as the machine gains stable stability and will evenly mow the lawn. Three wheels are a more economical option, but there will be practically no differences in performance, unless an individual feeling of comfort and some moment of aesthetics: no more. Two wheels are good in that they provide the ability to quickly maneuver. You need to adapt to this, and after that it is a very convenient option.
The metal sheet also cannot be chosen at random. First of all, dimensional parameters: 30 to 50. This is the approximate point from which we need to move further.
The width of the frame, as a rule, is realized in approximate frames from 30 to 50 cm. This is the most optimal option. With depth, you also do not need to overdo it: it is enough only if the engine does not crawl out of bounds.
Knives must be made of mild steel, and the size should vary between 2 - 3 mm (length) and 20 - 50 mm (width). Pay attention to the steel itself: it should not be fragile. For example, a hacksaw blade for wood has everything you need in order to use it as a lawn mower knife. The handle is welded to the lawnmower itself: do not forget to leave a place for winding the cable!
The manufacturing process is not as complicated as it seems, the main thing is to approach it wisely and adhere to the prudently outlined plan.
Allocate one day to build a lawn mower: one day is enough for you and proceed. To get started, take the chassis from the cart, you can strollers and use it as the basis for the subsequent installation of the metal sheet.
Next, take the pipes and make a pen. Its shape should resemble the letter “p” with individual errors, that is, you equate this element for yourself. We make the height in accordance with the growth and weld to the existing platform.
We cut a hole in the same platform: the motor shaft will be placed here. Pay attention to the front of the frame: you will need to make a protective arc or the grill itself, but always from mild steel. In principle, the grill is even better, because it can in some way provide you with security. This applies to cases where the knife slides directly from the shaft or helps to make a certain fixation for the stems, as a result of which smooth beveling will be ensured.
Regarding the fastener process: fasten the grating strips (upper and lower) using bolts, then screw on the wire previously prepared for this. This type of grill provides clearance for the knife. According to technical parameters, it is 1 cm in front, and 2 cm from the bottom and, respectively, from above.
Finally the engine. As noted earlier, it is installed directly on the platform. On the shaft itself, you will install a knife that has already been sharpened, and in the middle, pre-make a hole. The installation of the knife must be treated carefully, namely: twist the knife in your hands, of course carefully. If the knife rotates easily and without any obstacles, then this is what you need.
With all this, you should not forget about safety. Do not turn the mower in the rain or when the grass is still wet.
Nevertheless, this is a self-assembled lawn mower, not a factory one, and the wires can first fail, and secondly they are so insulated that you can completely trust them.
Of course you should not give a lawn mower to children. The lawn mower is not a toy! Finally, before mowing the lawn, check the grass for any foreign objects. And if the knife sticks, do not try to solve the problem until the lawnmower is de-energized.
Thus, it is not difficult to assemble a lawn mower on the basis of the details of the washing machine. Adhering to the above plan and adding a little effort, you will get a working machine that will serve you for more than one year.
