One of the most common questions buyers ask when choosing an electric lawn mower. Which knife drive is installed? Today, manufacturers use two types:

  • Straight;
  • Belt.

Belt as a drive: what is good and what is bad

During belt transmission, the mechanical energy of rotation of the engine shaft to the knife shaft is transmitted using a flexible belt and two cylindrical pulleys (master and driven). The belt is pulled on these rollers, forms a closed structure. The main element of the transmission. In fact, a flexible belt. It is made of rubber or dense synthetic fabric.

The belt can be:

  1. Flat;
  2. Toothed.

Why is the belt needed in this design? The engine that is installed in this type of lawn mower. Brush. And the number of revolutions can reach several tens of thousands, so there is no way to install the knife directly. And the gearbox in this case can add extra weight, inconvenience in maintenance and high cost of repair. A belt. The cheapest and most practical option to reduce speed and a person can independently replace without visiting service centers. Now let’s look at all the pros and cons of a belt drive.

For all its simplicity and lightness, the belt drive often gets accusations of low productivity, quick wear and the need for frequent replacement. Why is this so? At the beginning of the article, I hinted at the correct application of the technique and compliance with the grass mowing regimen. I did this on purpose, because users often neglect the rules of mowing grass. It must be mowed in the morning no earlier than 10, but no later than 11 hours. Then it can be easily mowed, the mower does not overheat, and on a hot summer day, when the temperature can exceed 30 degrees, you will not harm either yourself or the tool with which you work. If you try to adhere to this rule, then the probability of failure of both the belt and the entire assembly is reduced.

Benefits:

  • Simplicity and profitability of production;
  • No additional parallel shafts in the composition;
  • There is protection against overload and jamming;
  • The level of vibration and noise is attenuated by special dampers-gaskets, which increases the service life of the lawn mower;
  • This unit does not require lubrication and high maintenance costs;
  • In case of failure, the repair price may not be so high and in most cases, you can fix the lawn mower yourself.

Disadvantages:

  • There is a large load on both shafts;
  • Low belt service life;
  • Recommended operating temperature. Not higher than 35 degrees;
  • The increased size of the case, which is not always acceptable;
  • For less wear and tear of the belt drive, it is necessary to periodically adjust the tension roller.

Direct drive. Advantages and disadvantages

With direct drive, the mower has an induction motor. It does not require replacement of brushes, there is no additional unit where it is necessary to change the belt. The mower body can be a little smaller and lighter. And if a powerful motor is also installed, then this is a rather serious argument that may lead you to buy just such a lawn mower. And if you look at all these facts, a logical question arises. Why make a belt driven lawnmower, because an asynchronous line has so many advantages? In fact, there are also pitfalls, and quite substantial ones.

As we know, in our country, unfortunately, there are old power grids and the voltage, as a rule, does not correspond to 220V there. Practice shows that outside the city in private homes, where electric garden equipment is mainly used, the voltage is, on average, at around 180 to 200V. What is the danger for an induction motor? He cannot gain the required number of revolutions, his efficiency drops, and the knife, in turn, ceases to mow grass effectively. In the brush. The opposite is true. It increases the starting current to maintain the desired speed and maintains operational efficiency. But because of this, the engine heats up faster. Let’s look at everything "behind" and "against" direct drive.

Pros:

What Wire Is Needed For A 1400 Watt Lawn Mower
  • High efficiency and great durability;
  • It has low noise and reduced vibration transmitted to the body of the lawn mower;
  • The service life reaches 3-5 thousand hours, especially when installing universal swivel joints in the shaft;
  • Gives high torque at low engine speeds.

Minuses:

  • Heavy in weight, although smaller in size than the belt structure;
  • Price may be higher than belt drive;
  • When a knife of a lawn mower hits a stone or a thick branch, the overload goes directly to the engine, which is fraught with serious damage and complete failure, which, in turn, can lead to the replacement of the lawn mower completely.

Findings

As you can see, belt and direct drives are characterized by efficiency, efficiency, weight, size and even price. But their main difference is reliability and durability. Therefore, when choosing, you need to build on the working conditions of the lawn mower.

Identify the main points for yourself:

  1. How often will you mow? If rare, the grass will be tall and stiff. So, it’s better to take a lawn mower with a reliable direct drive. For fast and frequent mowing, a cheaper belt drive is better. Moreover, with frequent operation, the belt will wear out and burst quickly. It can be easily and simply replaced;
  2. What is the area of ​​the lawn? For small lawns and lawns there is no need to pay big money for direct drive. For a large territory, it is worth spending money, because the mower will have to work for a long time, and a stable asynchronous motor with direct transmission. Much more reliable and powerful.

In general, the direct-drive design, although a bit heavier and more expensive, will last a very long time without breaking. Especially if, before mowing, clean the area from stones and thick branches and take care of stable voltage. And if there is no way to do this type of cleaning, then it is quite possible to stop on a lawn mower with a belt drive.
