Owners reviews

Leonid, Samara:

“I have an electric mower k-CMI 1000, which I received as a gift from a cousin. I am happy with it! Of course, the time of use is not enough to make global conclusions, but at the moment I like it. It is not too heavy, only 7 kg, so easy to transport and work with. At the beginning it was hard, but Motokos is really useful in the garden. With a regular mower it is very difficult to mow weeds, to cut or pull. I recommend this product! “

The brand CMI is part of the OB chain of stores, under which they sell very affordable garden equipment, including gasoline lawn mowers.

The distinctive feature of such lawn mowers is a very low price, while the quality is at the level of slightly more expensive Chinese counterparts.

That is why you should not expect from CMI CMI brand products or fantastic reliability. All of them are designed only for home use and mowing small well-made lawns or lawns.

Why choose CMI gasoline lawn mowers?

The main reason for choosing these machines is their cost, because the cheapest model costs 8.5 thousand rubles, while the performance of models from other manufacturers is noticeably lower.

Moreover, when buying a machine at the OSH Hypermarkets, the buyer receives a warranty, which allows warranty repairs at special workshops.

Addresses and contact information of these workshops can be found in Obi Hypermarket by contacting a manager or a salesman. In the same workshops you can buy everything for maintenance and self-repair gasoline lawnmowers Obi.

Popular models

OB offers a small range of gasoline lawn mowers under the brand name CMI, and all of them are very popular with those who need the cheapest garden equipment. These lawn mowers are used only occasionally to mow small lawns or lawns near the house.

SMI 2,5 HP.

Although this mower is the cheapest one, it mows lawns much faster than many more expensive models.

The cutting height range is 25-75 mm, which is enough for all well-maintained lawns, but due to the low engine power (2,5 L) it cannot be used for cutting high grass.

The body and deck are made of impact-resistant plastic, so the device turned out to be very light (21 kg), which means that it is also good for physically weak people, such as women or teenagers who do not have a lot of muscle strength.

However, this plastic does not tolerate a lot of vibration, so attempts to storm the bush will result in cracks in the body, causing the motor unit to loosen and the mower to break quickly.

The design of the deck allows you to mow grass almost close to obstacles, and the small size makes the device very maneuverable.

The lack of lateral and rear discharge limits the possibilities of use, so this model can only work in mowing and coarse mulching mode.

The lack of wheel drive is not a serious disadvantage due to the low price and low weight, so even a physically weak operator will not have to strain too much to move the mower forward.

Here are the advantages of the model:

  • Low weight, so even women or the elderly can work with it;
  • The large mowing width speeds up mowing the grass.


  • Plastic body does not tolerate engine overload.
  • Lack of rear and side discharge modes deprives the mower of versatility;
  • The underpowered engine makes it impossible to handle weeds and tall weeds.

This small lawn mower is designed for cutting grass on small, complex-shaped lawns, where its size makes it difficult to use larger and more productive models.

Small mowing width (40 cm) slows down the mowing, but thanks to this the device is very maneuverable and lightweight (23 kg).

Mowing height range is 25-75 mm with separate adjustment (5 definitions). It is enough for efficient mowing of grass 10-15 cm in height.

Higher vegetation is recommended to mow in 2 passes, the basic amount of the surplus grass will be mowed in the first mowing, but the surface of the mowing area is very uneven, and the second pass will give an even surface of the mowed grass.

The CMI C-B-40 can only operate in rear discharge mode, including the use of a 45-liter grass bin. This makes the mower a very versatile mower. Therefore, it is purchased only in cases where only this type of weed ejection is required.

The cost of such a mower on the OSH website is about 10,000 rubles, and the significant advantage is the two-year warranty.

Here are the advantages of the CMI C-B-40:

  • Due to its small size, the device is well suited for cutting grass on landscaped areas of complex shape.
  • The low weight allows this mower to be used even by women and the elderly.
  • The warranty period is 2 times longer than most Chinese devices.

Here are its disadvantages:

  • The lack of side discharge and mulching functions limits the use of the mower;
  • Small mowing width slows down mowing the grass.

CMI C-B-46.

Medium-sized mower with mowing width of 46 cm and a Briggs & Stratton engine.

For some reason, the manufacturer has not indicated the power, which means that the device is not designed for overload conditions and is intended for mowing grass only on well-maintained lawns.

The mowing height is standard for all CMI models and is 25-75 mm. Grass box capacity .

The CMI C-B-46 mower has a rear discharge for the grass catcher box connection, so it is not universal.

Like other CMI models, this model is lightweight (22.5 kg) and has no wheel drive. However, this is not surprising for a device that costs 13,000 rubles.

Here are the advantages of the model:

  • Due to the low weight, women or the elderly can mow the grass.
  • The enlarged grass catcher box is less likely to be empty.

The disadvantage of the CMI C-B-46 is that the manufacturer specified the engine power, it is impossible to determine the suitability of the machine for mowing tall grass and weeds, as the higher the vegetation, the more power the engine requires for its effect.

CMI C-B-51.

The cutting height range is standard for a CMI mower (25-75 mm, center setting), engine power is not displayed, so the machine cannot be used for mowing tall grass or weeds.

The weight of the device is 32 kg, and the drive on the rear axle facilitates the work of the worker, because he does not have to push the CMI C-B-51 in front of him at the expense of his muscle power.

The average cost of this device is 15,000 rubles, and it also comes with a two-year warranty. This device is equipped with a “4 in 1” system, which we told you about here.

Here are the advantages of the model:

  • Large mowing width speeds up the mowing of the lawn;
  • Rear axle drive relieves the operator and allows him to work with the mower in a more comfortable environment;
  • The 4-in-1 system makes the mower versatile.


  • The model is not suitable for mowing tall grass and weeds;
  • Small wheels make it difficult to mow grass on uneven areas.
