Replacing the Lawn Mower Drive Belt • AURAMM.RU

Drive belts on walk-behind tractors are one of the most important parts, since it is thanks to them that the force from the motor is transmitted. Their unsuitable condition or improper tension leads to a deterioration in the quality of tillage and can cause breakdown of the unit.

The main reasons why a product quickly loses its usefulness:

various cracks, cuts, abrasions that occur over time during operation;
Incorrect placement of pulleys. If the pulleys are not located at the same level, the product will bend and very soon fray;
incorrect installation;
low factory quality of the product.

It is also worth carefully monitoring the location of the belts on the Cascade walk-behind tractor after reinstalling the engine - it may be necessary to align the pulleys along the axes of the grooves.

If your walk-behind tractor is not subject to heavy loads, it is advisable to loosen the belt tension rollers. This will significantly extend its service life.

Features of belts for walk-behind tractors Cascade

There are not many models of Perm Cascade walk-behind tractors on the market. And the more difficult it is to maintain this type of equipment, since all components must be selected specifically for a specific type of equipment. After all, even belts from walk-behind tractors of the same company, but of different models, can differ significantly. And such an alternative will result in rapid damage to the part and, possibly, breakdown of the walk-behind tractor itself.

Therefore, when selecting a new belt, it is very important to check the data in the operating instructions and the markings of the old part.

How to replace drive belts on Neva MB-1 and MB-2 walk-behind tractors: step-by-step instructions

Based on the differences in the location of the belts on these two walk-behind tractors, we will consider the processes separately.

For Neva MB-1:

disconnect the shield by unscrewing 2 bolt ties and removing the protective casing from the gear pulley;
do not completely unscrew the connection of the guide pulley;
smoothly remove the reverse belt;
loosen the ties, move the limiter pins and remove the front transmission belt;
We take new serviceable belts and apply them to the grooves of the required pulleys. After this, we secure them with the bolts that were removed in the previous stages.

"Neva" MB-2:

disconnect the shield and casing;
be sure to remove the spring that provides tension;
unscrew the screw fasteners and unscrew the stops that hold the belt on the motor pulley. Before moving on to the next step, you need to make sure that the grooves of the motor shaft and gearbox are in the same plane. According to instrumental measurements, the non-flatness between them should not go beyond 0.01 cm;
if necessary, adjust the pulleys. The easiest way to do this is to move the motor in a longitudinal plane;
we adjust the tension pulley by adding or removing an element located between the disk and the bracket;
install a serviceable belt for the Neva MB-2 walk-behind tractor, starting from the gearbox.

Further assembly of the V-belt mechanism is carried out in the reverse order of the disassembly process. An important point that users often miss is the discrepancy in the range between the protective casing and the belt accessory. According to the technical documentation, it should be at the level of 2-3 mm.

What is the size of the belt on the Cascade walk-behind tractor?

Cascade walk-behind tractors have forward and reverse belts. As a rule of thumb, reverse belts are less likely to wear out because they are used less. Their markings and sizes also differ. For forward belts, these are products marked A-1180 and A-1213 GOST-1284. For reverse gear, these are products marked A-1400. The value “A” in this code means 13 mm.

The most suitable belt for replacement would be the belt from the Mole walk-behind tractor, some models of which have identical technical characteristics.

How to choose the size of belts for Neva walk-behind tractors?

To ensure good tension and long service life of not only the entire drive train, but also the transmission, the belt size must be precisely selected for the specific model of the Neva walk-behind tractor. Belts that are too long, as well as belts that are too short, will quickly wear out and create additional stress on the gearbox or motor.

It is not difficult to deal with this problem if you have at hand a detailed table with dimensions presented below.

For the most popular Neva models you will need:

drive belt type A-1180 – only for MB-2;
2 reverse and forward belts - Z(0)-1400 and A-1213 - for MB-1.

Craftsmen have learned to install automotive-type belts on such walk-behind tractors: AVX 13 × 1175, YaMZ-8401 from BelAZ, YaMZ-238AK, YaMZ-8401 and even from Don brand combines. Experts advise that the size of the selected belt, even if it is not original or not the one recommended by the manufacturer, should not deviate from the permissible value by more than 0.5-1%.

In addition to the above, before purchasing, it is necessary to externally check the belt: there should be no defects, scratches, protruding fibers, or bends that could harm the cultivator during operation. A high-quality belt is one that retains a clear factory pattern and does not stretch by hand.

Walk-behind tractor Cascade: replacing belts

To quickly and efficiently make a replacement on the Cascade walk-behind tractor, follow this algorithm:

Stop the engine and put the gear in neutral.
Remove the protective cover.
Remove the old belts.
Install a new belt. Remove the pulley from the engine, pull the belt onto the gearbox pulley, and reinstall the motor pulley.
Make sure that it is not twisted and that it is positioned strictly parallel to the grooves of both gearboxes.
Reinstall the protective cover.

Also, do not forget about the rules for storing and using the product itself to extend its service life. Do not bend or stretch it - this may deform and damage the part. Monitor the condition of the pulley and promptly remove minor defects (scratches, chips, scratches, cracks).

How to change the belt on a Neva walk-behind tractor?

The simplicity of the basic device of the MB-1 and MB-2 modifications allows you to replace faulty drive elements without seeking help from a specialized workshop.

To do this you will need:

Carefully remove the old belt, being careful not to damage the tension rollers and other important parts located nearby.

To do this, it is necessary to sequentially dismantle the protective shield and the main factory casing, built-in for additional belt protection; Carefully remove the spring from the structure, which is necessary to tension the drive element; Unscrew the fastenings in the form of screws and the standard stops that serve to hold the belt on the standard engine pulley; Inspect the location of the handle of the power unit shaft and gearbox - they must be strictly in the same plane. In the Neva MB-1 and MB-2 walk-behind tractors, deviations in the location of the handles are possible by no more than 0.1 mm; If there is such a need, adjust the location of the pulleys by carefully moving the engine in its longitudinal plane; Adjust the installation location of the tension pulley - this is necessary for the appropriate tension of the installed belt; Install a new drive element - it is important to start installing the belt from the side of the gear part of the walk-behind tractor. The video will tell you in detail about manually replacing the drive element.

The procedure for replacing belts is performed in the same way for both the Neva MB-2 walk-behind tractor and its analogue MB-1

In each case, before installing a new element, it is important to inspect the installation site and thoroughly clean it of debris, if necessary.

Belts for walk-behind tractor "Cascade"

Today, few people can boast of the desire to dig up vegetable gardens and fields, plant potatoes, and then harvest them.
This work is always fraught with health consequences. We live in a world where there is no point in doing everything manually, because there is special equipment for this. If you have a small area, then it is not advisable for you to purchase expensive professional equipment. Walk-behind tractors will do all the work perfectly. There is a huge selection of them on sale and it will not be difficult for you to choose the right model for yourself.

In this article we will talk about belts for walk-behind tractors. Although at first glance it seems that this detail is not the most important, the quality of tillage will directly depend on its characteristics. With insufficient tension and heavy loads, the shafts will slip, thereby preventing motion transmission. Simply, the walk-behind tractor will not work.

The importance of the drive belt in the design of Neva cultivators

The design of modern Neva walk-behind tractors is quite simple: there is a welded frame (supporting part) in which the engine is localized, the revolutions of which are transmitted to other components through the shafts. The chassis is usually represented by two small wheels. All mechanisms are controlled using combined levers located on the handles of the devices.

Any Nevsky walk-behind tractor contains 2 types of shafts:

Crank;
Spreading.

The job of the drive mechanism is to transmit speed from the crankshaft to the camshaft.

Depending on what acts as a belt, the drive can be:

Chain - represented by a hinged chain connecting the drive and the driven sprocket, between which the traction potential is transmitted;
Belt - transmits power due to friction forces.

The former are less difficult to care for, do not require stress and, when they are compact, provide good performance. Belts, with their price and simplicity, compensate for rapid wear and significant overall dimensions.

Thanks to the large number of modifications released under the Neva brand, they all belong to the group of belt-driven equipment. An important advantage of these cultivators is the overhead camshaft, which contributes to more efficient cooling and, therefore, less wear on the belts themselves.

Technical recommendations

Before choosing a walk-behind tractor, or rather its model or belts, in order to repair the unit, you should first study not only the characteristics of the equipment, but also the land itself, which will need to be processed in the future. If any spare part is selected correctly, the unit from the Salut company can easily cope with the following tasks assigned to it:

hilling;
harvesting;
plowing potato crops;
fertilization;
harrowing;
landing.

In addition to the characteristics of the future harvest, it is worth paying attention to the characteristics of the soil. If we consider heavy soil, the unit must be equipped with a powerful timing belt of the generator. Given its purpose, it is used to create a drive between the camshaft and the crankshaft. If the tension is insufficient, the shaft may pop out. This will also reduce the actual power of the device.

Important! Other dangerous situations may arise due to a diametrically opposite process. If the drive of the walk-behind tractor is constantly under increased load, this will lead to rapid wear of the elements of the running system.

Considering all of the above, we can conclude that the efficiency of the walk-behind tractor depends on the correctness and quality of the choice of any element of the system.
At the same time, the manufacturer does not set restrictions related to the selection of spare parts or their analogues. This is interesting: the dimensions of the belt for the Oka walk-behind tractor.

How to replace the belt on a walk-behind tractor with your own hands?

If the owner of the unit sees a problem that has arisen, he must put the gearbox in neutral, turn off the engine and move the device to the place where repair work is carried out;
The protective cover and worn belts should be removed. If they are not completely torn, but are in critical condition, cut them with scissors and remove them;
If a person sees that one of the belts is still in good condition, both products should still be replaced, because when installing a new one, the level of tension will change and it will bear the main load, thereby reducing the period of quality operation. Therefore, pair replacement is a charming procedure;
It is necessary to remove the pulley from the engine drive shaft, and put new belts on the pulley located on the gearbox shaft of the walk-behind tractor, which cannot be removed;
We take the “separated” pulley and carefully pull the belts onto it. Only after completing the “changing of clothes” do we mount the part on the motor shaft. An important point: we must not forget about the key, because without it the pulley will not rotate;
When installing the belts, you need to place them on top of the tension rollers and make sure that everything is done correctly (there is no distortion);
At the end, place the protective cover in place and enjoy using the walk-behind tractor with new belts.

The size of the belts on the Cascade walk-behind tractor and the procedure for replacing them

Different units use belts of different sizes. Thus, the Cascade walk-behind tractor uses A-1180 or A-1213 GOST 1284 belts for forward travel, and A-1400 belts for reverse travel. The prefix “A” stands for 13 mm.

Before proceeding with removing or replacing the belt, it is necessary to dismantle the protective casing, unscrew the pulley, which has three streams; it is attached with a key and a locking ring to the shaft. When removing the ring you need to be careful not to break it. The material from which it is made is very fragile.

Next, we should move the reverse belt pulley forward to tighten the three-groove pulley, after which we can remove the belt without interference. If it is simply very worn, you can cut it off with a knife.

Next, we check the belts and, if necessary, replace them with exactly the same ones. If there are two of them on the walk-behind tractor, then it is better to replace both of them at once. If you replace only one belt, they will have different degrees of tension, and the new one will take on more load, which will lead to its rapid wear.

We begin to assemble everything in reverse order. We tighten the belts onto the gear pulley, then install the motor pulley, check the tension rollers and make sure that the belts are installed evenly, without distortions. Don't forget to put the protective covers in place and secure them.

A cultivator is a technical tool that performs the following functions:

weed control;
plowing the soil;
loosening;
applying various fertilizers to the soil.

During intensive use, some components and parts of the unit may become damaged.

. Therefore, you should purchase the necessary spare parts in advance (perhaps on the day of purchase of the cultivator itself). This will allow it to return to functionality immediately after a breakdown.

The main elements of the cultivator are a gearbox, levers, a fuel tank, a frame, a motor, a support, a wheel, and a blade of the working element. Torque transmission is ensured by a gearbox that is built into the engine.

The knives of the machine are designed to cut layers of soil, easily mix and chop them. Operating the device is effortless.

The Mole cultivator has gained popularity among gardeners and gardeners due to the fact that it carefully removes weeds and mixes various fertilizers with the soil.

Prominent representatives of the same reliable and high-quality equipment are cultivators, and. For more information about the work of the Mole cultivator, watch the video:

All this contributes to intensive plant growth and large yields.

The Mole is a model of a Soviet and Russian cultivator, which began production back in 1983. Its production was established by the Moscow Machine-Building Enterprise named after. Chernysheva.

It is a leading company in the defense-industrial complex, employing the best specialists in the country. Now the production of the Mole cultivator has been established in the city of Omsk.

Today the complex includes several production facilities:

Belt

From time to time, when operating the Mole walk-behind tractor, you may notice the belt slipping.

This problem can be avoided by installing 2 belts. Proper installation requires an oversized idler pulley with driven pulley.

The roller is placed on bearings. To improve the cultivator, you only need to remove the old one and install a new roller.

The unit uses an A-750 drive belt.

It is 750mm long, 8mm high and 13mm wide.

Product composition:

cord;
wrapping layer;
technical volcanic rubber.

The main task of the belt is to transmit torque from the motor to various components of the device. The belt is marked according to size (mm). Can be used at temperatures from +30 to +60 degrees.

Used in traditional drives, used in agricultural units. The belt is one of the most important elements

cultivator. In order for the device to work at full power, original belts are required.

The belt for the mole 710 cultivator is installed on units with a Russian engine. The profile of the product is 13 mm.
