Owners of beautiful and green lawns using lawn mowers may run into problems while working. In this article we will tell you how to repair gasoline lawn mowers with your own handsand also you will find out the common causes of breakdowns of this device.
Features of the structure of lawn mowers
Most mowers are driven by pushing from behind, but there are also models that can be controlled using the steering wheel. 
A specific type of device is designed for different jobs. Small ones deal with the usual middle section, and large mowers with steering control are used for large lawns.
But all devices have the same structure. Let's start with the case. Gasoline mowers have aluminum and steel enclosures.
With the help of the lawn mower that you choose to give, you can also mulch the lawn.Aluminum They are used much more often, because such a body is durable, lightweight and resistant to corrosion. Steel housings contain a powerful and heavy engine.
Electric Lawn Mowers gasoline is lighter and their body is made of ABS plastic. It is used to create car bumpers. 
The wheels of the mower should be large in diameter, so they will easily overcome irregularities. They also create less pressure on the ground and do not injure the lawn. Bearings will provide high reliability and durability.
Many manufacturers make the two front wheels swivel. This allows for increased maneuverability. The front wheels turn around an axis and due to this you do not need to raise the mower to change the direction. Let's talk about knives. All of them, as a rule, are rotary and are located on the working shaft. The diameter of the knives determines the width of the mower.
The rotor performs following functions:
- support knives at a certain distance from the ground;
- rotates quickly and cuts grass;
- has blades serving as a fan. The air flow from the fan carries cut grass to the collection box.
Collector - This is a big bag or plastic box with holes for air. It is easily removed and the content is discarded. 
Many mowers not only cut the grass, but can grind it into flour. This process is called mulching. In this case, do not use the grass collector, as the greens after mowing will serve as fertilizer.
Important! When working with the lawn mower, follow the safety instructions.
The main causes of lawnmower problems
Next, we consider the main causes of breakdowns of this unit and the corresponding types of repair mowers.
Rattling and crashing at work
If you hear a rumble and a rattle inside the mower during operation, this means that the engine bolts are loosened. Another option for extraneous sounds is a poorly fixed unit body. 
All this can be repaired. Check each mower bolt connection and, if there is an unacceptable play, tighten the loosened bolts.
Intense vibration when working
Another most common breakdown is strong vibration and sudden, uncontrolled movements during work. The problem is damage to the mowing knife or weakening of the cutting mechanism on the mower motor shaft.
In this case, you can simply tighten the loosened bolts or replace damaged knives, if you notice broken items.

Whistling while mowing grass
If you hear a whistling sound while the mower is operating, the problem is getting inside a foreign object. 
In this regard, the video in the aerator is blocked. To fix this problem, just turn off the movie and remove the unnecessary item.
Lawn mower reserves grass
If you notice that while mowing the grass, the mower leaves the green behind it - this means that the knives blunted. It is enough to sharpen removable knives or buy new ones.
The mower works intermittently or the engine does not start at all
If the mower works intermittently, this means that the drive belt has worn out and needs to be replaced. If during inspection of the unit you notice that the clutch cable is stretched - adjust it. 
Does the lawn mower start? Take the unit to a service center for qualified repair. The problem may be in the candles or making fuel. In such cases, simple replacement of a spark plug or refueling with gasoline will help.

Change of oil. In this case, the lawnmower engine must be still warm so that the remaining oil can be easily drained. When pouring oil, check its level. Carefully ensure that no dirt gets into during pouring.
At the end of each season we recommend replace air filter mowers. Since during work the dust settles in it. At this time, you can check the spark plugs. 
If you see that there is a small residue on the candle, white bloom or oil residue, then it will be enough to clean it or replace it with a new one. For any other damage, it is better to replace the spark plug immediately.
