Despite the fact that the blades of the lawn mowers are made of high-quality steel, from time to time they need to be updated. Fortunately, it does not need special skills and equipment for this, and today we will tell you how to sharpen the mower knife itself, without worsening the quality of the metal.
Cut the surplus of grass from the lawn, even if the mower knives have obviously blocked. However, while shooting will be flashed in the longitudinal direction, turning into a fringe. A few days after the cat, the grass will become Zhauki and a few more weeks will be hurt. The slice should be smooth and neat, then it will delay literally in a few hours and the lawn will always be juicy. This requires that the knife is sharpened almost perfect.

How to remove the knife with a lawn mower
Before proceeding with a partial disassembly of the lawn mower, you need to protect yourself and it. If a device with an electrically driven is enough to simply turn off from the network, then gasoline lawn mowers require preliminary preparation. First of all, you need to remove the ignition cap from the spark plug. Further, the fuel leaks should be deleted, that is, either drain the tank, or put a hermetic rubber membrane under the cover and overlap the fuel tap. Furning the lawn mower should only in the direction of the handle, unless otherwise indicated in the instruction manual. Before turning the lawn mower, do not forget to take the hose of the exhaust of crankcase gases so as not to pour oil.
In the lawn miles are used knives of different configurations. In the simplest case, this is an ordinary two-blade plate complex formHowever, the knife can be composite - the upper blade is intended for mulching beveled grass. There are also four-sabot knives that can be both composite and in a common database.
The knife can be mounted either by one bolt in the center through the shaped washer or two bolts with a landing on the centering hole or pin. In any case, the thread on bolts is right, respectively, you need to unscrew counterclockwise. To block the shaft from rotation, substitute a barbed bar, fastened to the ground. It is advisable to remember or outline the position of the blade (s), in order not to confuse anything at the reverse assembly. Twisted bolts temporarily push into loose holes.
Cleaning and editing
When the knife is removed, it needs to be the first thing to clean from the nanile dirt and hardened herbal juice. The easiest way to do this is to use metal crawling. The knife strip must be clean on all sides: not until metal brilliance, but without the smallest nagwood fragments.
Often because of getting into working area Solid objects, such as stones and sins, the blade is very significantly deformed. Most blades themselves are not direct, but the cutting edge and a strip of 10-15 cm from it should be examined for the availability of local bugs and curvatures. This is done using a short level line.
It is possible to straighten the blade with a conventional hammer, which has a slightly rounding edge. The knife is placed on an even massive support (anvil), then weak metal blows are attached correctly. You need to rule the knife, ranging from the edge of the curved area, gradually moving towards the center. The brown body of the blades is a small problem, but it is very important that the cutting parts are straightened into one straight line. You also need to check the discarding blades that are often inflicted from the blow. If on different shoulders, the blades will be rendered at different angles, it will worsen the air flow and the beveled grass will not be mulched.
Disassembly
If the knife for a long time It did not grind, on it with high probability will appear highlighted chips. They need to get rid of them, bringing the edge of the blade at a uniform angle along the entire length of the cutting plot. Please note that the edges on each side may be somewhat, in which case the lawn mower forms several cutting planes.
The lawn mowers knives have a one-sided sharpening, the descent of which is usually drawn up. To remove the descent under the right angle, you should use an electric sharpening with a carbonated stone, and in the absence of such a small file. It is very important to remove the metal evenly with both blades. Therefore, keep the same pressure and at least approximately consider the number of passes sharpened.
Small deviations of the sharpening angle are not critical, however, the greater the descents will be displayed, the greater there will be a knife resource. When removing the shape of the blade, it always moves on the grain to avoid the formation of large burrs and outflows. Use a grinder for pre-sharpening should not - overheating may degrade the quality of the metal. However, it is possible to install a petal or barbed disk for emery paper.
Sharpening blades
The purpose of the sharpening directly is the elimination of small edges and excavation of the descent into one straight plane. The presence of a "peel" on the blade leads to a rapid decrease in sharpness, and with a rounded descent, there is too much impact on the cut stems. In addition, the blade with a rounded form is polluted much faster.
The sharpening of the blade is best to make a flat emery bruse grain grain of about 400-600 grit, more "delicate" stones use no particular sense. Soak the lump in the water of water for 10-15 minutes and periodically wet during the sharpening. The knife also grows on the grain with a small break of the bar from the center of the styled area to the edge.
When sharpening, try to stick to the same stone position to maintain a permanent corner. As with the remavation, sharpening should be carried out at that condition so that the same amount of metal is removed on opposite blades. This condition, however, optionally strictly observe when sharpening four-odd knives.
Edit edge
When the blades are sharpened, they must be corrected. This is done using a segment of moisture-resistant emery paper with a graininess of about 600-800 grit. Paper must be mixed with water and roll into a cylinder with a diameter of 100-150 mm.
Editing Pursuits the goal to remove the slightest burrs and obsolence, because of which the thinnest edge of the blade can wrap up. Folded into the cylinder sandpaper should be slightly pressing the shutter plane and stretch smooth motion from grain. It is also recommended to make a smooth shift from the center to the edges.
When breaking down and sharpening, all manipulations were carried out only with one side of the blade. In the process of editing, the knife is also processed from the back. Here the paper is pressed almost close to the body of the knife, but with a slight inclination towards the edge. The force of climbing the paper when editing is completely small, but the movements need to make quite a lot, achieving the elimination of large rinks on a brilliant descent, which remained after sharpening.
For reference: It is possible to sharpen the mower knife with a rejoint by analogy with a conventional manual oblique. This, however, requires a special fit - grandmother, as well as a specific skill. But with such a way of acuction, it is not necessary to balance the knife.
Checking balancing
Before installing the blade back, you need to make sure that its shoulders have at least about the same weight. Otherwise, when working, vibration will arise, which will not affect positively on the durability of the spindle.
Balancing is carried out mainly for double-sided single and constituent knives, four-haired are not so strongly susceptible to the imbalance. To check the knife, you need to push the smooth bar in the horizontal position. The blade is put on it through a hole in the center, after which attempts are held to install it strictly horizontally. If one of the shoulders weighs significantly more than the other, the knife will be steadily rotated in one direction.
The weight equation shoulder is carried out by stepping a small amount of metal from the back side of one of the shoulders of a knife. It is not necessary to achieve ultra-precise balancing, but the knife should be delayed in a strictly horizontal position for a few seconds. When balancing is carried out, you can put the knife in place and finally update the look of your lawn.
The blades of knives of various lawn mowers are almost always made of high-quality steel, however, despite this, they are still periodically to be sharpened. And the main thing is to do it so as not to worsen the quality of the metal. However, no special tools And the skills are not required for this, and to cope with such a task will be easily able to any dacket!
Why do you need to sharpen the knives of lawn mowers?
Of course, cut off the surplus of juicy green grass from your favorite lawn is quite real and a knife with dull edges. But the grass as a result of such manipulations will begin to settle down (this bundle will go preferably in the longitudinal direction), gradually turning into a neakkurat bchroma. And after a few days, she will unhappy at all and can even try for several weeks. That is why sections should always be neat and even - in this case, they are tightened only for some few hours and allow you to maintain a spectacular juicy green color of the lawn. And so that they were such, you need to periodically sharpen the knives of the used lawn mowers!Remove the knife
Before proceeding with such an important event, it is important to try to protect themselves to the maximum and the garden gadget. Especially concerns this gasoline lawn mowers (models with electric drive are easily neglected by elementary disconnection from the network): First, it is necessary to release the spark plug from the cap, and then you need to completely eliminate the likelihood of fuel leakage. It can be done in two ways in two ways - both by draining the tank and by placing under the cover of the rubber hermetic membrane and overlapping the fuel tap. If there are no other instructions in the instructions, the lawn mower turns exclusively towards the handle. And before making it, the hose intended for exhaust gases should be forged - it will help to avoid oil leakage.
Knives B. various models Lawn mowers can have the most diverse configuration, however, the threads on the bolts are always unscrewed the same - counterclockwise. And in order to prevent the possible rotation of the shaft, you can put under the knife firmly stunned into the ground bar. And, of course, so that nothing is impact, installing the knife back, it is important to try to remember or even draw the position of the blades.
What to do next?
The removed knife must be cleansed from hardened herbal juices, as well as the dirt nulissed on it. The easiest way to do is using metal crawts. Then the surface of the knife is examined for any curvature or bugs. If there are those of them, they are straightened by a conventional hammer with a slightly rounded edges of the slaughter. As a rule, the knife begins to rule from the edges of the curved area, gradually moving to its center. Also it will not hurt to check and often discarding the blades, because if they are flexing under unequal angles, it will inevitably entail a deterioration in the air flow, as a result of which the cutting herb simply will not be properly mulched.The next step is to remove the descent. First get rid of the elevated chips, deriving the edge of the blade under equal angle On the entire length of the cutting part. And to remove the descent under the desired angle will help a small file or equipped with a carbarund with a carbonic chicken. At the same time, it is important to try to remove the metal with a knife as closely. But the Bulgarian is not categorically recommended for these purposes, as it can significantly worsen the quality of the flavored blade.
Cut the blade
For sharpening blades, a flat emery shelter usually use, which is ranging from 400 to 600 grit. Before proceeding with the drainage of the blade, the bar is recommended to soak minutes for ten and fifteen in soapy water. Periodically during sharpening this manipulation must be repeated. And the knife should be sharpened by stretching the bar in the direction of the center of the stacked area to its edge. At the same time, it is desirable that the stone is in the same position - it will contribute to the maintenance of a permanent corner. And, of course, with the blades of the knife should ideally become the same amount of metal!
The sharpened blades must also be "corrected" - for this it will take a small piece of moisture-resistant sandwich, the grain of which has a range from 600 to 800 grit. Paper is wetted with water and turn into a cylinder, the diameter of which reaches about 100 - 150 millimeters, and only after that proceed to "edit". And before installing the knife, it is important to make sure that the weight of his shoulders remained the same, otherwise (in case of unbalance) there may be extremely unwanted vibration. To check the balancing, first in the vice horizontally clamp a smooth bar, and then through the hole located in the middle, the blade is put on it and they also try to install it horizontally, watching his behavior - one shoulder should not significantly drag another. If the balance is not observed, then some of the shoulders are sharply some of the metal. And only after that you can set the sharpened knife to the lawn mower again!
The knife for the lawn mower has 2 cutting edges. In this case, the metal plate is monolithic, and not divided into 2 parts, as it is powered by one rotor. And this is precisely with this, the greatest difficulty is connected - the proper balancing of the knife. If one of the parts is broken more than the second, then will be unbalanced. The blade during operation will vibrate and accelerately wear the rotor drive. What kind of tools can be sharpened by knives? Could it be that you have to work a stone?
Required toolkit for sharpening
The first thing to pay attention to is how the knife is removed correctly. Lawn mower C. gasoline engine In no case cannot be deployed up the disc and protective casing, since oil and the harbores remaining in the cylinders will fall into the area of \u200b\u200bthe carburetor.
Turn the mower must need a side, and in the direction of control handles. If possible, it is advisable and not to do this, but take advantage of the overpass. On the extreme case, the lawn mower is simply placed on 2 stools, and then the knife itself is removed. To do this, it needs to be blocked (for example, scrap or wooden beam) And alternately unscrew 2-3 bolts from below. You should be neat, as the washers will be removed.
After removing the knife, it should be carefully examined for the presence of chips and sizes, which are obtained when the lawn mower is hit onto a stone or other solid object. If there are such, you need to remove them with the action. The easiest option is to rest all the edge. However, if you do it on one side of the blade, you will have to get the same and on the other, regardless of whether there are chips there. This is all done due to the correct balancing. Already further starts directly sharpening knives for lawn mowers.
For editing and sharpening cutting edges will be required:
- bulgarian;
- vice;
- drill with grinding adapter (discs);
- file;
- the skin (sandpaper) is about 250 grit.
It is necessary to start with the alignment of the cutting edge (if its stable). For this purpose suitable Bulgarian With grinding circle or grinding stone with a large graininess (up to 400 grit).
The standard sharpening angle is 30 ° (is carried out only on one side).
However, it is recommended to clarify this information in the instruction manual for the lawn mower. Some manufacturers of the edge on the knife for the lawn mower are made under 20-25 °. Thus, a large sharpness is achieved, but permissible wear before re-sharpening decreases.
How to make a knife sharpening
The easiest I. effective methodHow to sharpen knives for a lawn mower is to use a drill with an adapter for grinding discs. It is not worth counting on the "factory sharpening", as it is performed using a diamond disk, but it is possible to restore the cutting edge to such a method for 5-10 minutes.
The disc is selected with shallow graininess, in the range of 800-1500 Grit. For sharpening a traditional knife, 4-5 such skins will be required. During the heating of the edge, it is necessary to follow the balancing. To do this, it is enough to suspend the knife on the rope, skipping the one through the central hole for the attachment. If you turn into some of the sides, it will not, everything is in order. Otherwise, a slightly needed to go again with a skin on the opposite side for alignment of the weight.
After sharpening using a disk, it remains only to perform the final liner of the blade cutting side. Experts recommend this to use grinding stones with very fine graininess, ranging from 1.5 to 4 thousand Grit.
For each side, the knife will have to spend at least 15 minutes, clearly withstanding an angle of 30 °. To achieve the most the best results SAMI top part The blades are made rounded. It should be borne in mind that with the final eyeliner, the angle changes to a larger 2-3 times. At first, the transition from 30 to 35 ° is made, then up to 40 °. Literally 2 passes after changing will be more than enough. Such a form of blades is done for greater resistance to the appearance of sowers.
The knife for the trimmer (referred to the model of the mower with an electrically driven) is sharpened by several times. There will have to use only a file or diamond sharpening. Perfect option — grinderwhere the disk with a diamond spraying. But as a rule, sharpening the knife for the electric lawn mower does not perform with their own hands. This is done by qualified wizards when using special equipment (laser heating edge).
Edit cutting edge after damage
If part of the cutting edge was damaged after hitting a stone or some metal detailsBut the knife itself was recently drained, then the most ordinary Musat will help straighten the situation. It is desirable to use high-quality variations from ceramics, and not from steel or aluminum coated with abrasive material. Even the Musat that is used to edit kitchen knives is suitable. The only warning is the walls of the tool quite quickly. That is, it is for editing the edge of the knives of the lawn mower to better use a separate device.
It should not be hoped that the first time it will be possible to achieve the perfect sharpening of the blade. SAMI frequent problemwhich arises from newbies - it is powering right corner at 30 °. For these purposes, a machine with stones (with large grains) from Lansky will be useful. it manual Machinewhich allows you to set a certain angle when driving grinding stone And to withstand it throughout the level of alignment / sharpening edge. There is such a set relatively inexpensive, and the set of stones is enough at least 20-30 sharpeners.
The blades of knives of various lawn mowers are almost always made of high-quality steel, however, despite this, they are still periodically to be sharpened. And the main thing is to do it so as not to worsen the quality of the metal. However, no special tools and skills are required for this, and any dacket will be easily able to cope with such a task!

The sharpening knives for the lawn mower must be performed at the first signs of poor-quality work. This may indicate an uneven bevelled grass, eliminated with the roots of bushes, an increase in the operation time of the tool, increasing fuel consumption. Unlike the braid, which was trying to work in the early morning, on dew, the mechanized tool is desirable to work with dry grass. Wet grass faster and much more densely scores the casing and other tool cavities. Therefore, in case of emergency work tool, it is first necessary to clean the casing from the pissed residues. After cleaning, it is necessary to inspect the cutting edges of the knives and determine the need for sharpening.
Unlike braid, to work which they tried in the early morning, it is desirable to work with dry grass with a lawn mower.
Tool preparation
Some manufacturers of mechanized lawn mowers do not recommend turning the tool so that the oil in the crankcase does not fall into the piston. This problem can be solved in two ways:
- merge oil from the lawn mower;
- install it on supports that allow you to work under it.
Most tools can be tilted towards the handles to move, after removing the grass drive. The space formed is usually enough to clean and access knives. On an electrified tool and trimmers with all types of drive knives, after cleaning, can be removed in any convenient position. When removing knives from any tool you need to take necessary measures Security preventing the device to start the device. If the tool does not have a shaft blocking function from rotation, you should fix the shaft of any affordable way. You can use a wooden segment of the required sizes as a knife stop.
Removing knives with lawn mowers
Good sharpening quality can be obtained when using a sandpaper with a device for treatment at a certain angle.
Knives on many models are mounted with a bolt, located in the center, with an extra washer or special bracket. The bolt needs to be replete with a horn key or head at 19. If the turning is difficult or lacking effort, you need to knock down the bolt with a hammer. Blows should be unsalted, with high frequency.
You can spend several series of shocks. If after that it fails to unscrew the bolt, the compound must be polished by brake fluid or peps-cola. Leave in such a state for several hours. Many specialists confirm the ability of peps-cola to facilitate the spout of threaded products.
You need to use different levers and amplifiers to be extremely careful not to break the head of the bolt or do not break the shaft fixing mechanism.
If it is impossible to remove knives independently contact the specialists or to the service workshop. With minor damage to knives and free access You can try to sharpen them without removing the tool.
Methods of sharpening knife
After removing the knife, you need to correctly appreciate its condition. Knives of many models pass special thermal processing to increase hardness. Typically, such data is specified in the manufacturer's instructions. If there are dents and bends, the knife can be aligned with a hammer on a smooth solid surface. Optimal option will be use blacksmith Anvil. In the absence, you can use the railway railway, cut smooth sheet metal The thickness of more than 16 mm or the segment of metal rolling sufficient strength. The product that is cracking during alignment is not further processing. Knives can be molded in the following ways:
Sharpening operation is more convenient to perform with a fixed tool by moving the knife in a circle.
- hand tool;
- bulgarian with a set of circles;
- electric drill with a nozzle;
- emery machine.
After aligning the knife and removal, the dentin on the edge can be sharpened. Depending on the availability of the work tool, you can perform different ways. For most options, it is desirable to have plumbing vice capable of securely fix the part in the desired position. Small damage can be removed when processing a file or a coarse-grained stone for sharpening. The final knife turning should be performed by fine-grained stone or sandpaper 0th or 1st room. Manual sharpening requires certain physical effort and time spending. You can speed up the process in the presence of an electrician with an appropriate nozzle. The emery wheel with the shaft must be fixed in the drill cartridge, connect drill. Knife secure in any available way. Run drill, start sharpening the edges. The effort should be small, moving the circle over the surface smooth. You can not overheat the edge of the knives. When working the knife periodically needs to be wetted. More convenient will be the option on the contrary: if possible, fix the drill, move the knife by stone.
Processing Bulgarian
Cannon dents can be aligned with a hammer on a flat solid surface.
If the knife has significant damage, it is easier to cut the cutting edge to the desired distance and sharpe again. For trimming, you need to measure the necessary size using a caliper or other marking device with the required accuracy.
At the same time you need to remember the balance of the knife. Crimping should be performed on both sides to the same value. After trimming, you can sharpen the surface. Sharpening operation is more convenient to perform with a fixed tool by moving the knife in a circle.
If there is speed controller on the grinder, it is desirable to choose the optimal mode of operation of the tool so as not to overlay the cutting edges.
For sharpening, it is necessary to change the circle from the cutting destination to the sharpening, remove the metal at the required angle until the sharp edge is formed. Sharpening before required quality Performed by stone or sandpaper manually.
Sharpening knives on the sandpaper
Good sharpening quality can be obtained when using a sandpaper with a device for treatment at a certain angle. It is necessary to install a coarser-grained stone, fasten the knife in the device, adjust the sharpening angle. Process cutting edges to complete alignment. Then change the circle to fine-grained, sharpen to the required quality. Processing must be performed by smoothly moving the knife, without stopping and sharp movements. In the absence of a device, you can sharpen a knife holding it in your hands. If in the set of the emery machine there is a felt polishing circle, the surface of the knife can be treated to a mirror gloss. This processing will allow to extend the life of the knives and the entire tool. Metal will become more resistant to corrosion. The surfaces will stick less grass creating an imbalance during operation. The load on the bearings and the power unit will become below.
For grinding surfaces you need to install a felt circle on the machine. Run the machine, on the rotating surface to apply a goe paste (slightly press the lump of paste to a circle). The coating should be uniform. Then take the knife, press the surface to the felt circle and move in any direction. When processing, it is important to ensure that the cutting edge and other angles do not come towards the rotation of the circle. All edges need to be grinding only at the output position. Oncoming traffic will damage the circle and possible injury. When the color of the circle surface is changed from green to black, you need to re-apply the paste layer and continue processing. It is necessary to monitor the knife temperature. The operation of grinding is also capable of cutting the metal edges.
Balancing a knife
After sharpening the edges of any of the described methods it is necessary to check the balance of the knife. Under the balance, the same weight of the products of the product is meant. In the mounting hole you need to insert a pin, a nail, a screwdriver or any row of round. Raise to a small height. If the knife saves a strictly horizontal position, everything is in order with the balance. With a slope into one of the parties - the balance is broken, you need to restore it. Restore can be quite simple. On the outgoing down side, you need to remove some metal in the same way as the sharpening was performed. Metal needs to be removed from the little, periodically checking the equilibrium.
Conclusion on the topic
For long-term operation of knives in spring period After the snow, it is necessary to carry out the cleaning of the spacing area.
Collect and remove stones, bottles, metal and other items. If there are hemp from bushes, herbal bumps them also need to remove and level the surface of the lawn.
