How to replace a belt on a lawn mower

It is difficult to move the mower

  • When the lawn is difficult to move across the lawn, you may be trying to clear the grass too high and need to adjust the mowing level. If the rollers or wheels become stuck, inspect them to make sure there are no clippings of grass or debris. Most likely, they need to be removed and cleaned.
  • If air intake is obstructed, the lift will decrease on the mower’s airbag and make driving more difficult. Lack of air causes the engine to overheat. Turn off the power and remove any remaining grass from the intake grilles.

Rotary mowers

They have one knife horizontally mounted on the motor shaft. The high rotation speed allows you to cut both grass and other plants. Some models have replaceable discs with replaceable plastic knives. they are easy to replace if necessary.

Some mowers have wheels, but most models run on airbags. Here, the engine rotates the impeller, which propels the air masses under the hood, creating lift. The metal knife is under the impeller.

  • Lever arm
  • Emergency stop and lock buttons.
  • Switch
  • Electric motor.
  • Hat.
  • Drive shaft (motor).
  • Housings.

Replacing Drive Belt On Bosch Lawn Mower

The lawnmower is a great alternative to manual mowing, which makes it easier and faster to mow grass in various places, including when conventional mowing simply does not rotate. But for comfort and convenience, there is a sophisticated modern mechanism that requires constant attention and regular maintenance.

Regardless of the manufacturer, all devices have the same design. Therefore, the repair of a home-made VIKING mower is carried out in the same way as the repair of other brands: Husqvarna, Calm, Bosch, Gardena, Oleo-Mac. A homemade lawn mower will be no exception, but repairing a breakdown requires basic knowledge. Consider the most common causes of engine malfunction and have your lawnmower repaired locally.

The most common breakdowns

Any technique will fail sooner or later. It is important to know how to repair the mowers, because in all cases there is no need to contact the service center.

Alternatively, you can simply flip the blade over with plastic knives to increase or decrease the cutting height.

All types of equipment can have grass containers.

Some gardeners prefer one that cuts the grass as little as possible and leaves the crop on the lawn like mulch.

The technique does not turn on at all

Long and damp grass can easily cover knives. Remove the plug from the power source and use a wooden object to rotate the cylinder on the other side of the blade until movement is free. This technique cannot be used for gas mowers.

Rotak 32. installing belt tensioner

The cylinder lawn mower belt will wear out, stretch and may break. Remove the belt cover and check if there is a gap or if the belt has just come out. Loosen the mounting screws and slide the small drive pulley towards the large cylinder pulley. Slip the new belt onto the small pulley and slowly rotate the large one, gradually putting on the belt. Move the pulley to the side to tighten the belt, then tighten the screws.

Be sure to check the belt tension before installing the cover. deviation should not exceed 4 mm (indicator may differ slightly depending on the model, detailed information in the user manual).

The mower does not cut the grass

In most cases, blunt or badly damaged knives are the cause. For best results, simply change your knife every year. Choose a knife that suits your model. When the knife is dull, it can be sharpened with an electric sander or file. Be sure to wear safety glasses and gloves when sharpening. The sharpening angle on both sides is approximately 30 degrees.

In cylindrical mowers, the gap between the knife and the cylinder should be less than the thickness of the paper. Some of the latest models have built-in controls. Otherwise, you will need to use wrenches and screwdrivers to make the necessary changes. Make sure the gap is the same along the entire length of the cylinder. To check the adjustment, insert a sheet of paper between the cylinder and the knife while rotating the drum slowly by hand. Adjust gradually on both sides until the paper is neatly cut at each point of the stationary knife.

Cylindrical mowers

These include spiral blades, the combination of which resembles a cylinder. A large toothed pulley located at one end drives a belt (in some cases a chain) and, on the other hand, attaches to the other a small pulley attached to the motor shaft. The motor can also move the roller, which moves the equipment on the ground.

  • Lever arm
  • Emergency off button and safe lock button.
  • Switch.
  • Filter.
  • Air intake grille.
  • Knife clearance adjustment.
  • Fixed knife.
  • Knife cylinder.
  • Large toothed pulley.
  • Drive belt.
  • Drive pulley.
  • Height adjustment lever.
  • Electric motor
  • Rink.
  • Power cable.

As the cylinder rotates, the blades press the grass against the knife attached to the cylinder, thus creating a cutting effect that resembles the principle of scissors. Any damage, even the smallest, wear, improper attachment of the knife makes the equipment less efficient. The cutting height of the grass changes after adjusting the position of the roller or wheels located at the front or back of the knife cylinder.

What does it consist of

Let’s consider this issue using an example of the principle of operation of a belt for a vega x pj457 180j lawn mower. And so, from two rows of rings of infinite direction, which are located parallel to each other directly in the region of the groove of the multiple so-called “elements”. They, in turn, are attached to each other in the form of a kind of ring. This installation is made in such a way that the groove itself has the opportunity, let’s say, to open precisely to the peripheral outer side.

It is important that this very element has the presence of the surface of a part of a protruding guiding character. This is necessary in order to hold a kind of ring in such a way that the special rings included in its devices simply do not separate from each other and from the groove itself.

It is worth noting that the surface called “guide” produces a formulation of a kind of pushing force in the direction of the inner side of the belt, thereby allegedly pushing one specific ring to one of the special end surfaces. This pushing component itself, which is directed to the inner region, produces a kind of attachment precisely to the lateral outer side of the ring, which is currently being pushed.

Lawn mower belt: aspects of selection and replacement

Today, most of the population uses such an indispensable and practical agricultural device as a lawn mower. Naturally, this tool has not only a high level of functionality, but also quite productive.

In addition, if you have at least minimal skills in the field of mechanics, then this kind of process will go smoothly and without any problems. For example, repairing STIHL mowers can be done with your own hands using seemingly ordinary things that can be found in any home.

Probably, it is not worth reminding that the drive belt is simply an indispensable and important element of the lawn mower mechanism, namely the drive area. It is important that the belt can undergo any breakdowns, let’s say, it can be stretching of its base, or it even broke, then naturally, in this case, you will not be able to use your technique, at least until you replace the old belt with a new one.

First of all, you should, from cover to cover, as they say, read the instructions for your device. Since, despite the general direct similarity between lawn mowers, the differences between them can also be quite significant, so you should not risk it, but you need to be as ready as possible for the process of replacing the belt.

After the necessary element is purchased, you can actually prepare for the replacement process. To do this, prepare a place where the “update” will take place. Since a clean surface and organization will positively affect the work itself.

So, the replacement process has begun. To begin with, using a wrench, unscrew the spring, coil, support element, actually remove the entire assembly.

After that, it is necessary to remove the belt itself, which is damaged, as well as its direct guides. It is important to note that in most cases they are made from clamps of the metal direction. You will need this information in the process of selecting the necessary components for replacement.

You must remember that you need to hold the belt while removing this type of addition. And only after they are removed, you can remove the belt itself. It is worth noting that it is much easier to remove these guides by using an adjustable wrench in the process.

Remove them together with the bolts themselves. In addition, pay due attention to their condition, since if they are rusted, then it is more expedient to simply replace.

The next step in our work is direct replacement. To do this, you need to get the purchased belt itself from the package, as well as a kind of sub-belt. After that, install a new belt and its actual guides and, using an adjustable wrench, simply tighten them.

Then try starting the engine of your lawn mower and observe how the belt behaves. You must remember that the belt must not catch on other elements, and pay due attention to whether it rubs against any surface. If the process goes, say, so correctly, in this case, you can safely collect the “node” back. All replacement is completed, and you can start working!

Choice aspects

First of all, it is worth noting that the high-quality work of a lawn mower directly depends on how much its owner looks after it, as well as how often the necessary diagnostic and repair work is carried out. over, timely replacement of consumable materials is also important, in fact, which also include belts intended for this kind of technology. So, it will not be superfluous to find out, for example, about the necessary spare parts for the mtd lawn mower.

It is worth noting that it is this important and irreplaceable element of the device that most of all requires attention and is most often replaced with a new belt. It is important that each product of this kind necessarily undergoes a kind of certification, this is what you should pay due attention to when buying a belt.

Considering the fact that lawn mowers today occupy a leading position among agricultural technology, it can be unconditionally concluded that the demand for this additional element will never fall, at least until humanity so rapidly acquires this kind of equipment for its lawn.

Actually, let’s now figure out what kind of belt you need to buy for your “iron pet”, as well as what you should pay due attention to in the first place in order to make a correct and practical purchase.

  • the brand of the belt itself;
  • its immediate dimensions.

In most cases, the greatest demand is for the original kind of wine code, but if such belt size indicators are not available, then you will need to personally measure your belt.

To do this, it is necessary to measure both the height and length and the width. Therefore, you can easily find the best option for your lawnmower. And this article will tell you how to choose a lawn mower.

How does it work

First of all, it is worth noting that a kind of transmission, which has gears in the gear direction, directly ensures a certain change in the gearbox, which has gear steps. The same applies to the continuously variable transmission, which in turn is responsible for the direct variation of the gear ratio.

It is these features that are available as a kind of transmission, designed specifically for the return of power, which is produced between certain rotating elements.

It is important that when the belt itself rotates a pulley of a leading character, and which at this moment, let’s say, is applied to the pulleys, leading and driven, then this becomes the cause of a certain friction force, which is observed precisely between the pulley, leading and special element.

At the same time, a so-called “compression” force arises, which in turn applies directly to the elements themselves in exactly the direction in which they are located, that is, in the direction where the greatest coefficient of their thickness is relative to the torque of the driving pulley.

At a time when the force of a certain compression is already “sent” to a special element, which actually fully maintains contact with the driven pulley, then the force of a kind of friction produces a formulation precisely in the part where the pulley, driven and the element are in contact.

Consequently, by means of this kind of mutual transmission of force, a torque is produced intended for the movement of the follower pulley. Actually, in this way, its operating power is transmitted to the belt itself. You can find out exactly where the belt is located in such units on the example of the device of the Polish rotary mower.
