Ranking of the best lawn mower knives for 2020

For summer residents and gardeners, summer is a hot season, when you need to have time not only to grow all the plants, creating comfortable conditions for them, but also to ensure that the adjacent territory is well-groomed. In order for the site to have an attractive appearance, it is necessary to mow the grass at least once a week. Electric and petrol lawn mowers and trimmers are used for this purpose.

If the site is neglected and overgrown with weeds, or you need to remove thickets of cultivated plants (raspberries, etc.), ordinary fishing line will not cope with the task assigned to it. For this purpose, you need to purchase a special knife. It can be supplied complete with the mower, or purchased separately.

In this article, we will tell you how to choose blades for an electric and gasoline lawn mower, we will rate their popular models based on customer reviews, and also decide what to look for in order not to make mistakes when choosing.

Selection criteria for knives for gardening equipment

In the minds of ordinary people, the cutting elements of such devices should resemble a kitchen knife, but this is completely wrong. First of all, let's define its purpose. Unlike fishing line, the blade acts on the stems in such a way as not to chop them into small pieces, but to cut them exactly (this does not apply to mulching modifications). In order to do this, they have a peculiar shape - curly with a certain sharpening angle. You can also find models with a mulching function - cutting vegetation into pieces.

• Functional.

There are three main types of cutting elements on sale - straight, curly, mulching. The first type is distinguished by a flat surface, as well as rectangular edges. The peculiarity of the curly nozzle is that it bends at a certain angle from the center to the edges. The latter type has a special shape, reminiscent of the English letter Z, and there may be (not always) notches along the edges. It should be noted that the functionality of most attachments implies mulching, but this function is more pronounced in a specialized blade. In almost all such rigs, the edges are curved to one side. This is done so that the grass is "attracted" to the rotary element, and after cutting it is transported in a certain direction to the compartment for collecting vegetation. The cutters may look different from each other. They can be bladed and in the form of a cutter. Models of the first type can be of three varieties - straight, with rounded edges, with pointed edges. Milling (disc) models in appearance resemble a sprocket from a bicycle - an even and straight disc from the middle goes to sharp multidirectional edges.There are also modifications with a stepped transition - each element is located slightly higher than the previous one. The length of the protruding edges can reach several centimeters.

• Dimensions.

Manufacturers recommend choosing a cutting element of such a size that it is equal to the mowing capacity of the device. If you choose a smaller product, the mowing effect will be worse, and if you choose a larger one, damage to the instrument motor or injury to the operator may occur. The required characteristics can be found in the lawn mower passport. According to the manufacturer's recommendations, you need to buy a cutting element from the company that is listed among the acceptable ones. Despite the fact that on the market you can find special adapters that allow you to attach a blade from another manufacturer that is not intended for use in this brand, experts do not recommend doing this in order to avoid equipment damage.

• Manufacturing material.

According to the advice of experts, it is recommended to buy products made of stainless steel. They have increased strength characteristics, as well as resistance to moisture and plant sap, which will quickly damage the steel product. The minimum indicator of hardness on the Rockwell scale is 55 units and above. The worst parameters will lead to the fact that the tip will quickly become dull and require sharpening. There are also plastic knives. They are considered safer to work with, since when hitting a stone, the rig can fly apart and hit a person. Due to the softer structure and lighter weight, the plastic product is not capable of causing significant damage to the operator.

Sharpening rules

Separately, it is necessary to mention the sharpening of the blades. It is carried out at an angle of 30 degrees. A sharper angle will make the point too thin, it will be damaged from the slightest contact with coarse plant fibers. An obtuse angle will break the plants, not cut them, which will affect the quality of the mowing. It is recommended to sharpen the cutting element once a season - at a moderate load. Removal and installation of the plate should only be carried out by qualified personnel, as improper installation could result in injury to the operator. To remove the product, it is necessary to unscrew the fastening bolt from the head, then carefully remove the element. It is recommended to carry out all work with gloves, as you can accidentally cut yourself.

If you notice that vibration appears during the work, it is recommended to check the balance of the plate. To do this, it must be removed and hung on a nail with a wide head. If the knife tilts to one side, it is necessary to align it. To do this, you need to carry the cutting element to the turner, and he will grind off the excess metal. It is worth noting that this is not the best way to solve the problem, and the best way is to find the money to buy a new attachment.

What to do if the lawnmower stops mowing

Most often, there are two situations in case of problems with mowing: the grass is not mowed, or the rotor with the cutting element does not rotate at all. In the first case, there can be two options - the blade is dull or damaged (the problem is accordingly eliminated by sharpening or replacing the device), or the cutter is incorrectly installed (according to the rules, there must be a distance of at least one millimeter between the stationary head and the rotating part).

There are situations when the rotor does not rotate. To solve the problem, you need to do the following: check if something is interfering with the free rotation of the cutter, if grass, rope or other foreign object is wrapped around it, if the drive belt is torn, if the power cord is connected, if the switch is functional, there is whether the voltage in the mains, whether the motor has overheated (a heat regulator is usually built into such a technique, which controls the maximum permissible temperature in order to avoid damage to the motor).
