How to reduce the speed of the walk-behind tractor

Why the single-axle tractor Oka does not start:

  • the tank is out of fuel;
  • the oil level in the crankcase is below normal;
  • the ignition system of the Oka walk-behind tractor requires adjustment, or is out of order;
  • carburetor adjustment required;
  • filters are clogged and require replacement;
  • Spark plugs are burnt out, smoked or damp;
  • oil seals are out of order.

For reverse:

The belt is dismantled manually by loosening the adjusting bolt. The new belt should not sag, nor should it be under strong tension. Correct tension is when the belt flexes slightly when applied by hand.

How to increase the speed of the walk-behind tractor

There are two ways to increase the speed of the walk-behind tractor:

  • installation of large wheels;
  • replacement of a gear pair.

Let us first consider how changing the wheels helps to increase the speed of the cultivator. The standard wheel size of almost all mini-unit models is 57 cm. When changing, tires that are 1.2 times larger in diameter can be installed. Usually, wheels of 70.4 cm are used. Despite the small difference, the speed of the walk-behind tractor increases markedly. If the arches into which the tires are inserted will allow you to insert wheels with a large diameter, then you can try adding centimeters.

Let’s consider how to increase the speed on a walk-behind tractor in the second way. Like any technique, the cultivator has several speeds, which are controlled by gears. Usually cultivators move at a speed of 2 to 15 km / h, while the large gear has 61 teeth, and the small gear has 12. To increase the speed, the gear pairs of the reducer are replaced. We increase the number of teeth, thus the maximum speed of the walk-behind tractor is achieved.

It is recommended that the replacement be carried out by professionals and preferably in specialized centers, since parts turned with a minimum error will affect the operation of the motor. Not only the replacement of the gear is important, but also the correct selection of the pulley.

What to do if the speed jumps out on the Oka walk-behind tractor, and the gear change does not work:

  • it is necessary to inspect and, if necessary, repair the gearbox. replace broken sprockets, chains, bearings, oil seals;
  • adjust the semiaxis decoupling mechanism;
  • check gear fixation.

We offer you to watch a video on how to change the bearing and replace the oil seal on the gearbox of the Oka walk-behind tractor:

Oka maintenance

Maintenance of the walk-behind tractor includes several stages:

  • Daily work before and after use.
  • Change of oil.
  • Scheduled inspection.
  • Long-term storage.

Lighting for the Oka walk-behind tractor

Many owners of this technique strive to modernize the device as much as possible, to further increase the comfort and ergonomics during work. One of the modernization methods is to install light (headlights).

It is not so difficult to make light on the Oka walk-behind tractor, it is enough to find and connect a generator of the required power to the unit. The connection algorithm is as follows:

  • a button is placed on the steering wheel;
  • the generator is attached to the walk-behind tractor;
  • headlights are attached to the front of the motorized device;
  • through wires, a connection is made from the button to the generator and to the headlight;
  • the wires are insulated.

The more powerful the generator, the brighter the light will be; many people prefer to install automobile electric generators on this agricultural technique. We offer you to watch a video on how to independently put the light on the Oka single-axle tractor:

Required materials and tools

To begin with, you need to accurately determine the technical characteristics of the structure: the type of transmission, its gear ratio, the distance between the shaft and the axle of the wheelset. The work will need the following tools:

  • welding machine;
  • electric drill;
  • a set of files and files;
  • measuring instruments (vernier caliper, ruler);
  • yew;
  • a hammer.

The tool must be visually inspected and checked.

Important! It is strictly forbidden to use a defective tool in order to avoid causing accidental injury to yourself and others.

Do it yourself

How to make a creeper for a uniaxial tractor with your own hands? The mechanism is very similar in design to a gearbox. Its inclusion in the work of the walk-behind tractor redistributes part of the tractive effort to additional attachments. The work on manufacturing the device can be conditionally divided into several stages:

Council. You should take up the manufacture of home-made devices only if you have experience and when assembling, strictly adhere to the algorithm of the necessary operations.

How to adjust the speed?

Sometimes it turns out that you want to change the speed of movement of your motoblock device: increase or, which happens quite rarely, decrease it.

To increase the speed of movement of motoblock units, one of the following two methods is usually used:

BCS 749 walk-behind tractor running Berta brand 26″ Flail mower

  • replacement of wheels with large ones;
  • replacement of a pair of gears of a reducer.

The usual wheel diameter of almost all motoblocks is 570 mm. Most often, when replacing, tires are selected with a diameter that is approximately 1.25 times larger than this. 704 mm. Although the difference in size is relatively small (only 13.4 cm), the speed of movement increases significantly. Of course, if the design allows for larger tires, you can try to increase the speed gain.

The gear pair installed in the wheel reducer usually consists of two gears with 12 teeth for a small one and 61 for a large one. You can change this indicator by 18 and 55, respectively (only for specialists in agricultural machinery service centers), then the speed gain will be approximately 1.7 times. Do not try to carry out the operation to replace the gears yourself: it is very important here to select not only high-quality parts with minimal errors, but also the appropriate pulley. The gearbox shaft retaining plate also plays an important role.

Logically reasoning, reducing the speed of movement of the walk-behind tractor can be achieved by performing diametrically opposite actions. to reduce the diameter of the tires or the number of teeth on the gear pair.

A possible solution to increasing the speed is to adjust the throttle switch: when the machine is turned on, move it from the first position to the second. To reduce the speed of movement, return to the starting position. Of course, to change the speed downward, you do not need special reducers. it is enough not to switch to high gears.

Also possible solutions to the problem of increasing the speed of the walk-behind tractor are replacing the motor with a more powerful one and upgrading or installing a clutch system (in some outdated models it is not provided).

It can help to increase the speed (especially on uneven terrain or heavy soils, where slippage of the equipment is frequent due to insufficient weight of the unit) and the installation of weights. They can be made with your own hands from metal parts. Weighting structures are installed on the walk-behind tractor frame and wheels. For the frame, you will need metal corners, from which a self-made removable structure is formed, that is, you can easily remove it if there is no need. Additional ballast weights are attached to this removable additional frame. The wheels need discs made of steel and solid iron blanks with a cross-section in the form of a hexagon. These parts are welded and inserted into the hubs. For reliable fixation, cotter pins are used, which are installed in specially prepared holes.

Of course, if there are no round steel elements at hand, you can replace them with almost any material at hand: reinforced concrete products or even flattened round plastic flasks, inside which sand is poured.

Do not forget about maintaining balance: the weights on the wheels must be equal in mass, and evenly distributed over the frame, otherwise there will be a skew, due to which, when performing turning maneuvers, your unit may fall to one side.

To speed up a walk-behind tractor with a trolley in bad weather conditions. snow, slush, soil sour from torrential rains. you can put caterpillars (if the design allows). This method requires the installation of an additional wheelset and the purchase of rubber tracks of a rather large width. On the inner side of the track, restraints are attached to securely fix the rubber and prevent it from jumping off the wheel pair.

Also for this purpose, you can replace the native gearbox with a similar device with a low gear. to facilitate overcoming obstacles.

And do not forget about prevention: change the oil more often, regularly lubricate all the components of your mechanical friend, monitor the condition of the candles, replace worn parts with new ones.

If you take good care of the machine, follow all the recommendations for operating the device, carry out regular preventive maintenance, then a single-axle tractor will give the maximum of its capabilities in terms of speed and performance.

DIY creeper for walk-behind tractor

Auto mechanic specializing in agricultural machinery

Gone are the days when it was necessary to spend almost the whole day to cultivate a small plot of land and work for wear and tear. Well, whoever had a single-axle tractor. everyone in the district envied such an owner. This is not the case now. The motorized agricultural mini-machinery occupies a leading position in terms of the number of sales. Additional equipment that is used in walk-behind tractors and the power of a mini-tractor allow you to successfully process large areas of personal plots. Extra strength is required when working on heavy soils. For this, a reduction gear or the so-called creeper for a single-axle tractor is widely used.

They are installed together with pneumatic wheels and are practically not used on a wheelset with grousers. Reducing the speed and speed of the walk-behind tractor allows you to increase the tractive effort of the unit. It will not be difficult to make it yourself.

Ways to increase speed on a walk-behind tractor

Many farmers are interested in how to increase the speed of the walk-behind tractor. The most common agricultural technique is the single-axle tractor. With its help, the performance of work on land and personal plots is greatly simplified. Let’s consider how you can increase the speed on this technique. With an increased speed, the productivity and cross-country ability of the mini-car will increase, which can be used in any season and weather.

Drawing

When planning the execution of work, you should always remember the importance of drawing up diagrams and drawings. It is advisable that they be done professionally. The drawing contains all the data for the manufacture of the model and its operation: the required torque, the number of shaft revolutions. He accurately explains the principle of interaction of structural parts.

Victor, Penza:

“I have an Oka DM-1 with a 6 hp engine and so its main drawback is a lot of noise. Therefore, the engine mainly performs its functions at medium speeds. I have been operating for 5 years, there are no Комментарии и мнения владельцев, I don’t even consider replacing the belt and candles, these are consumables. My opinion: the most important thing is to change the engine oil once a season and clean the air filter. Alteration to this walk-behind tractor is not needed. I use my eye almost always in first gear, mainly for digging up potatoes, sometimes I also put a plow. I milling and using the machine with a trolley at second speed. Two speeds are enough for me, especially since the engine is powerful. The main disadvantages, in my opinion, are: it is difficult to check the level of the transmission oil, and it is difficult to change, you need to roll the hoot on its side. The handle bar is well adjustable. In general, I give a big plus to this technique “.

Nikolay, Rostov-on-Don:

“As the owner of this mini-tractor, I like the fact that ball bearings have been installed on the Oka for a long time, and if there is enough lubricant, the chains will live forever. In my village, all the neighbors have about 20 motoblocks, and all of them are Oka. There were never any problems with spare parts, and the chains never broke like in Chinese walk-behind tractors. They say that sometimes there can be a problem with switching speeds, but I did not experience such problems. Technique fire! “
