Motoblock kadvi mb 1d instruction manual. Motoblock "OKA": owner reviews

Motoblocks of the Kaluga plant KADVI of the OKA series are a truly popular unit for performing a wide range of agricultural and household work. The basic design has a good supply of hours. OKA is affordable for a wide range of consumers. Motoblocks of this manufacturer and series have been used since the eighties and are familiar to the consumer.

In this article, the author tried to reveal the maximum strengths and weaknesses of the OKA using the MB-1D3 walk-behind tractor as an example. The article used material from the official documentation "Operation manual" 005.45.0100 РЭ1. I also tried as much as possible to gather the information posted on the sites involved in the sale of agricultural equipment, to reveal the proposed topic as much as possible, using a number of published videos and user reviews.

The history of the creation of a walk-behind tractor

OKA motoblocks is the consumer name for motoblocks made on the basis of the MB-1 produced in the eighties, a compact apparatus up to 100 kg dry weight capable of performing various tasks. This device can be useful, both on a household plot, and in a small farm land. It can also be useful for the mechanization of labor-intensive processes in certain areas of large farms. Comes with a pair of rubber wheels and four cutters.

For quite a short time, this model range managed to get several modifications. This is primarily due to the engine, it has become more powerful. Improvements also affected the control system. Metal rods were replaced with cables. A weak point in the gearbox has been eliminated. All these changes have fully affected the MB-1D3 released in 2010.

Along with the above model, there are earlier modifications in the implementation, and even on the official website, sometimes the information is contradictory and contains a number of inaccuracies. In this regard, when choosing a model, you should carefully read the attached technical documentation, which is made at the highest level, in order to make the right choice.

Technical characteristics of the MB-1D3 motoblock

The motoblock is similar to most of this class. It is made on a metal frame in such a way that it is possible to hang removable equipment on it. At the same time, its own dry weight does not exceed 100 kg. Overall dimensions 1500x600x1050. Ground clearance 140 mm. Transport track adjustable 310, 570 mm.

Pulling force 100 kgf. Able to move in 2nd gear at a speed of 9k m / h. In first gear - 3.6 km / h. The turning radius is 1.1 m, the width of the treated surface is no more than 1200 mm. Plowing depth up to 320 mm.

Motoblock engine

This model is equipped with an engine of its own production KADVI DM-1M1 8-strong engine of domestic production. It is, on average, 8 kg heavier than its foreign-made counterparts, but at the same time, the torque is higher, and among the analogues presented in this line of OKA motoblocks, it is the strongest.

A few words about the design and principles of operation.

Four-stroke, single-cylinder, air-cooled, service life 5 years. According to consumer properties, it belongs to inexpensive, economical engines. In the course of production and operation, it underwent a number of modifications, it previously had a 6.5 horsepower engine, which put it at a disadvantage compared to domestic competitors.

The engine is equipped with a float carburetor. Plastic filters used in the carburetor make it easier to start the engine and provide it with throttle response and economy. A box-shaped muffler was designed for this engine model, which made it possible to reduce engine noise by a third. Due to the use of connecting rod bearings of a new type, it was possible to increase the engine resource by 3 times.

It is noted that the ignition system is designed in such a way as to make it easier to start the engine, regardless of climatic conditions. The accompanying documentation contains a number of recommendations for the operation of the engine. Not unimportant is the fact that the engine runs on fuel from AI76 to AI93.

Tests at factory stands have shown that, with proper operation, the engines of this model are capable of operating for 2000 hours without major repairs.

Motoblock reducer

Two-speed chain reducer with reverse at both speeds. The advantages include ease of maintenance and reliability of gearboxes of this type, the availability of spare parts in stock. Reducers of this type, if necessary, can be easily modified. The weak point of this type of gearboxes is needle bearings, but in models manufactured after 2000 this is already history.

After purchase, the device is ready for operation, the gearbox is filled with gear oil. It is worth remembering that the first 30 hours of operation of the purchased walk-behind tractor is a running-in period. Therefore, in order to avoid failure of the device, do not give maximum loads.

Regarding the gearbox, it is worth saying that with proper care it works up to 3500 hours without major repairs.

Clutch

Performs the function of a torque transmission mechanism from the engine to the gearbox. As in many foreign and domestic counterparts, the clutch in this model is V-belt. This is due, first of all, to the safety of operation of these units, to prevent damage to the gearbox and or engine. Also, the use of this type of clutch reduces the cost and efficiency of repairing problems that occur with the clutch. To extend the life of the drive belts, the machine must be warmed up before starting active work.

Brief overview of OKA models

Below is a table of modifications and characteristics of the engines used in them.

Next, consider attachments, which can be divided into several groups.

Attached equipment to the walk-behind tractor

Unfortunately, there are a lot of inaccuracies on the manufacturer's website in the description of both attachments and attachments, the site is clearly not being developed. To clarify the relevance of this or that information presented on the site, you can contact the manager. When writing the article, a lot of information was taken from the websites of companies involved in the sale of this equipment.

Attachments can be divided into several groups.

Active - equipment that is driven by a gearbox pulley:

• cultivator cutters (included in delivery);
• lugs - used to improve traction with the ground;
• rubber wheels;
• wheel weights.

Active equipment with V-belt clutch drive:

• mower;
• snowplow;
• brush active;
• potato planter;
• root crop grinder;
• branch shredder;
• water pumps.

Passive equipment:

• harrow and plow;
• hillers;
• potato digger;
• transport cart;
• motoblock shovel.

Operation and reviews of walk-behind tractor owners

Given the experience and a number of improvements, the OKA MB-1D3 is a noteworthy small-scale mechanization machine. The range of its application was described above, but I would like to dwell separately on the direct operation of the mechanism.

The purchased walk-behind tractor must be inspected before assembly, make sure that all the parts indicated in the passport are present. Make sure the warranty card is correct. If everything is in order, using the detailed diagram, assemble the device.

Before the first start, you should make sure that the transmission and engine oil are available. It is recommended to change the engine oil after the first 5 hours of operation. In the future, not so often, every 25-30 hours. The transmission oil is changed every 100 hours of operation. Total before overhaul 80 oil changes in the engine 1000 liters of gasoline. Transmission oil before gearbox overhaul 35 times.

In one of the walk-behind tractors, the owner said that he used the old MB-1 series walk-behind tractor, produced at the Kaluga plant in the eighties. With him and body kit remained. He took a modernized version of MB-1D3 for himself and noted the fact that the new model has a modified gearbox, namely (replacement of needle bearings with bearings according to GOST8338-75 - bearing 306). I was pleasantly pleased with the refinement of the control system, now some operations can be performed without turning by the walk-behind tractor itself, which was impossible on older models. As for the engine, a reduction in noise levels was noted.

A review was left in an online store that sells spare parts. The buyer thanked for the sale of the reducer and was delighted by the fact that new design reducers are now being sold.

Often, in addition to positive reviews, you can read or hear about the “disadvantages” of a V-belt drive - belts often break. As a rule, this is due to the fact that operating instructions are ignored.

One of the negative reviews was a review left about an adapter plate for an imported engine, a video was attached to the review, in which the plate was torn in several places. The above can be supplemented by the fact that a video was published with an imported engine with strong vibration.

Often there are improvements associated with the weighting of the unit to perform various operations. A video on reworking the reverse gear, or rather, on transferring it under the right hand, can be very useful.

One of the videos shows the use of a segment mower from a SALYUT walk-behind tractor. The mower is also great for all modifications of the OKA walk-behind tractor.

Equipment: cutters, pneumatic wheels, axle extensions, additional wings, coulter. The manufacturer has the right to change the configuration without prior notice.
