Replacing a knife on a Husqvarna lawn mower. Allows you to store a large number…

DIY lawnage

The regular use of a lawn mower requires not only caring for it, but sometimes repair. In many cases, you can return the efficiency of the lawnical mower yourself. Husqvarna produces three types of lawnmands. Electric (power supply from household power supply 230 V), battery and gasoline. The first two types do not require gasoline and are easy to manage and maintain. But they also have problems with the mowing of grass.

one. The electric motor of the lawn mower does not turn on. The engine is launched by one key/OPE on the control panel. If the engine does not work in the OL position, then the battery may be discharged or the power is not supplied from the network. The status of the battery will show the LED charge indicator and at a low level it will require its recharging. In the network model, using a multimeter or indicator screwdriver, the presence of voltage in the nest of the power cord is checked. If it is absent, the cable itself is checked, which must be de.energized. By replacing the damaged area of ​​the cable and checking the voltage, you can start work.

Non.rhythmic operation of the electric motor. Contacts should be checked that could oxidize and began to poorly skip electric current. Contacts should be cleaned with sandpaper and degreased. Then a special conductive lubricant is applied to the contacts, which will protect contacts from oxidation.

Reducing rotation of knives. When mowing tall grass or hard herbal, cutting nozzles can clog with grass. Remove the battery and disconnect the network cable. Take a small stick and clean the space around the knives from compressed grass.

four. Bad mowing. The grass is not cut off, but is knocked down with knives. This suggests that the knives are dull. Completely turn off the power supply and remove the lawn mowers knives. We fix the knife in a vice and pull the blades using an abrasive bar. Blade sharpening angle 25. 30 °.

In lawnmands with a gasoline engine, problems most often arise that are characteristic of all internal combustion engines.

one. The engine does not start. Is there a fuel in the tank? If there is, then the fuel mixture must correspond to the proportions of the manufacturer. Then we turn the spark plug.

Candle raw (sprayed with a mixture). This indicates an excess of the fuel mixture due to improper tuning the carburetor. The candle should be thoroughly wiped, and pull the starter cord several times with a turned candle. This will clear the combustion chamber from excess mixture. Carburetor adjustment is carried out in accordance with the operating manual (section “Maintenance maintenance. Carburetor”).

The candle is dry. The fuel mixture does not fall into the carburetor. So the problem is not in the ignition. Check the candle for the presence of a spark and if it is, then check the fuel supply. With a weak supply or its complete absence, we replace the fuel filter, which is extracted from the gas tank through the filling hole.

The candle is covered with soot. Incorrect tuning of the carburetor or the fuel mixture is prepared incorrectly. The twisted candle is cleaned with an awl and sandpaper. The awl is cleaned the space between the central electrode and the threaded part. The side electrode is cleaned with sandpaper. Set a spark gap (clearance) between the central and lateral electrode. The gap lies within 0.5. 0.65 mm. Damaged sealing copper washer should be replaced. Putting on a turned outer tip and pulling the starter, check the presence of a spark. In the absence of a spark, the candle is replaced with a new one and if the spark does not appear check the high.voltage wire.

There is no necessary power. If the engine does not develop sufficient power, then it is most likely that the necessary pressure is not created in the engine cylinder to combat the fuel mixture. Most likely the reason lies in the wear of the cylinder-piston group. piston, piston rings or crankshaft liners. For a more accurate diagnosis, the compressometer is inserted into the candle hole and the pressure is measured with its help when compressed. If the pressure is lower than the required, then the piston group must be replaced.

The engine smokes. If at low speed the engine works fine, and smokes high and stalls, then the problem can be in the muffler. It should be removed and peeled with a metal brush. It is advisable to rinse the muffler using a special detergent, dry with a hairdryer and put in place.

four. The engine gets very hot. With prolonged work with clogged air filter, the lack of air flow affects. Remove the filter and blow out a clean air stream. Filter put in place. With severe wear and damage, the filter is replaced.

Simple advice. The lawn mower refers to garden equipment for a long service life and in many ways to avoid breakdowns and other problematic points will help compliance with the “maintenance schedule” (see. Law mowing manual).

If you notice that in places there remains downstream grass where you have already mowed, this means that your lawn mower simply does not cut it properly. The knives wear out over time and must be periodically changed in order to maintain the efficiency of your lawn mower. You will support your lawn more healthy if you mow it less often by a lawn mower with sharp and clean blades. Replacing knives is quite easy and quick, if everything is done right. Start from paragraph 1 to get more information.

  • Also, it is best to do this when there is no gasoline in the mower. Wait until you work out all the fuel, or drain it with a pump hose. Typically, such hoses are sold in any household or auto store. This will prevent fuel flowing to the mowing housing.

Turn off the spark plug. It is better to stay on the safe side if the ignition of oil or gasoline from the candle suddenly occurs due to a short circuit or electric discharge. If you raised the lawn mower correctly, such a problem should not arise, but it is still better to be on the safe side. [1] X Source of Information

Classification of knives for lawn mower

To provide the lawn mower to the lawn of impeccable functionality for a long period, you need to know which supplies to install on the tool, what knives are there at all. To equip modern braids for the lawn, cylindrical (drum) and rotary cutters are used. The dimensions of the cutting elements fluctuate in a fairly wide range. from 33 to 51 cm.

In the instructions for the operation of lawnmands, manufacturers indicate which knife is compatible with a specific model. If you install a smaller knife, labor productivity will decrease, if more, the load on the engine will increase.

The safety of the operation of the tool depends on the material of the knife manufacturing. Manufacturers produce stainless steel and plastic cutters. Steel cutting elements are more functional, they quickly and effectively cut vegetation, are considered more reliable and durable. But when the lawn mowed on a stone or another hard object is hit by a metal knife can fly apart and injure the operator. A wreckage of a plastic knife is more harmless. A universal plastic knife with a large number of blades not only cuts off, but also grinds the grass, after which it can be used to feed the lawn.

Configuration of knife blades

According to the configuration, knives for the lawn mower are classified into blatant and non.disabilities. The former can have a different number of blades, but not more than 8. In the shape of the blades, the knives are divided into:

  • Simple. the blades are made in the form of long rectangular segments;
  • pointed. endings are dihedral bayonets;
  • rounded. there is a smooth curvature of extreme faces.

Helpable knives are also called cutters. In appearance, cutting elements resemble a disc saw. The number of cloves can reach several tens.

Removing the descents

If the knife has not sharpened for a long time, excited chips will be likely to appear on it with a high probability. They need to get rid of them, withdrawing the edge of the blade at an uniform angle along the entire length of the cutting area. Please note that there may be several edges on each side, in this case, several cutting planes form a lawn mower.

Lugus knives have unilateral sharpening, the descent of which is usually turned upside down. To derive the descent at the right angle, you should use an electric sharpener with a carborne stone, and in the absence of such a small file. It is very important to remove metal evenly from both blades. Therefore, keep the same pressure and at least approximately count the number of passages of the sharpener.

Small deviations of the angle of sharpening are not critical, but the smoother the descents will be displayed, the more the resource of the knife will be. When deriving the shape of the blade, it always moves to the grain in order to avoid the formation of large burrs and mix. You should not use a corner grinder for pre.sharpening. overheating can worsen the quality of the metal. However, you can install a petal or plate disk for sandpaper on an angular grinder.

Sharpening of blades

The aim of sharpening is to eliminate the small chips of the edge and remove the descent into one straight plane. The presence of a “saw” on the blade leads to a rapid decrease in sharpness, and with a rounded descent, there is a too strong effect on the cut stems. In addition, the blade with a rounded shape is polluted much faster.

The sharpening of the blade is best made with a flat sandpaper granularity of about 400-600 grit, more “delicate” stones do not make much sense. Soak the bar in the washed water for 10-15 minutes and periodically moisten during turning. The knife is also sharpened on grain with a small length of the bar from the center of the sharpened area to the edge.

When sharpening, try to adhere to the same position of the stone to maintain a permanent angle. As with the removal of descents, sharpening should be carried out with the condition that the same amount of metal is removed on the opposite blades. This condition, however, is not necessary to strictly observe when sharpening four.lobed knives.

Engine. “heart” of the lawn mower

The motor is the most difficult and responsible module of the braids for lawns, so the repair service is one of the most popular. The engine consists of several interacting systems, the details of which are made with high accuracy.

  • The piston group is a mechanism that transforms the energy of the expansion of heated gases into the rotation of the shaft.
  • Power system. a group of devices that supplies, dosing fuel and participate in the preparation of the fuel mixture.
  • Ignition. a system that creates a spark in the combustion chamber synchronized with the piston movement.
  • Gas distribution. a mechanism that provides air intake processes and the production of exhaust gases.

As a rule, on the lawnmands, light two.stroke engines with air cooling are used. These inexpensive motors have a simple design, but are quite sensitive to the quality of configuration. For their maintenance, it is necessary to have appropriate qualifications and equipment. Some actions can be performed qualitatively only in the conditions of a specialized service center.

Executive and other systems

The executive organs of the mower include all the systems using engine energy. First of all, it is a knife that cuts the grass, and devices for its release, collect or grind and scatter. Self.propelled models have a drive from the engine to wheels. In order to change the height of the mowing, the braid is equipped with appropriate devices. They are distinguished by the convenience of use and the complexity of the design.
