Czech segment-finger mower MF-70
Walk-behind tractors are used in small farmsteads. The owners of a walk-behind tractor will be able to prepare the land before planting, carry out maintenance or harvesting, remove snow in winter, and level the lawn in summer. To carry out the work, additional equipment is required: a plow, a mower, a rake, etc. Narrow-profile equipment is produced separately, which costs less than a walk-behind tractor and copes with certain tasks no worse. This includes the mf 70 mower. Let’s take a closer look at the design of the motorcycle model, its pros and cons. And the photos and videos in this article will help the reader better understand what will be discussed.
Application of a small motor mower
The Czech mower is an independent piece of equipment, powered by a small but powerful motor. The model is produced by the Czech company “Agrozet”. The company has been operating since the post-war years. They specialize in the manufacture of small agricultural machinery and various equipment for walk-behind tractors and mini-tractors.
The mf 70 mower has been designed for mowing soft grass. But the equipment has additional functions: snow removal and transportation (for transporting light loads). In fact, the equipment can replace a low-power walk-behind tractor in a small farm.
Thanks to its unusual design and low weight, the equipment can easily cope with grass in the most inaccessible corners of the site. And the price, which is lower than for walk-behind tractors of similar power and functionality, made the model popular in Russia. New and used models are brought to us. You can easily find them online at a more reasonable price. You can see in more detail how the fm 70 model of motor mower works and looks in the photo in this article.
Model description
The Czech mower MF 70 looks very similar to a walk-behind tractor with the corresponding attachments. The power plant is located on a two-wheeled frame, which has bifurcated control handles. In front of the device is a header, which is driven by the engine. Torque is transmitted via a shaft, which allows to significantly increase the resource of this element in comparison with chain and belt structures.
Despite its significant weight, operating the mower manually is not difficult at all. The support wheels also communicate with the engine, so no effort is required during operation.
Engineers carefully selected the weight and location of every part of this device, which allows for maximum comfort and controllability.
The mower can work in small areas
Features of the mower device
The peculiarity of the mower design of this model is that the operator of the installation is behind and can very accurately control the direction of movement of the equipment. In this way, a high level of operational safety of the equipment is achieved. On the steering wheel there are controls for speed, clutch, brake, and if necessary, you can also turn off the engine in an emergency using a special switch. In addition, the control can be adjusted in height.
In a motor mower of this type, the gearbox plays a load-bearing role. A gearbox is installed at the rear, which has 2 speeds for moving forward and one in the opposite direction. In the front part there is a power take-off shaft, with the help of which the header is driven. In addition to its main purpose, this mower model can also be used as a snowblower . For this purpose, a special attachment is installed instead of the header.

Device
The main feature of this motor mower can be considered a somewhat unusual design if you compare it with a walk-behind tractor. The load-bearing part of the walk-behind tractor was the gearbox housing. The rear part housed the gearbox, and the power unit was attached to the gearbox housing. On the sides of the gearbox there were wheel flanges in which the brake mechanisms were located.
In the front part of the gearbox there was a power take-off shaft housing, which was also intended to secure the working parts. This housing housed the shaft as well as the clutch. The mower's steering wheel was attached to the upper part of the gearbox, to which the controls for the accelerator, gearbox and clutch, power take-off shaft clutch, and brakes were located. The steering wheel itself was height adjustable.
The power plant used on the MF 70 mower was designated 1Z 22. This is a single-cylinder, two-stroke unit, the cylinder was located vertically. It was cooled by air. The power supply system is carburetor. The power plant was started using a manual starter.
Torque from the crankshaft was transmitted to the gearbox through a friction clutch. The box itself had two speeds for moving forward and one for reverse. From the box, torque was transmitted through a gearbox to the wheel drive shaft via a worm gear. The wheels on the MF 70 were pneumatic.

Working body
The main working body, the mower, was fingerless, segmented. The cutting apparatus consisted of a supporting beam, a segmented cutting blade, and a drive mechanism. On the sides of the beam there were shoes, with the help of which the height of grass mowing was adjusted.
The drive mechanism of the cutting apparatus was located in the housing. The assembly of the MF 70 mower with the working element was quite simple: The housing of the drive mechanism was put on the housing of the power take-off shaft, and the shaft itself was engaged with the drive mechanism. And the body of the working body was fixed with a locking pin.
Instead of a mower, the MF 70 could be equipped with a moldboard bucket or an auger snow blower, or a rotary mower consisting of one mowing rotor.
A coupling device was located under the gearbox housing under the power unit to connect the mower to the trailer.
Cost of equipment
Despite the fact that the mower of this model was developed in the last century, high-quality assembly and the use of durable alloys make it possible to operate such a device for an almost unlimited time. It will not be difficult to purchase the necessary spare parts for such agricultural machinery, so even old products can be restored almost to factory condition.
Used but in good technical condition models are sold at a price of 40 thousand rubles. You can reduce the price as much as possible if you look for a faulty mower that can still be repaired. Sometimes, such a model can be found at scrap metal collection points and purchased very cheaply.
Specifications
Before you buy an MF 70 mower, you need to carefully study the characteristics of such a device. Only by comparing the product with other similar installations, as well as with walk-behind tractors equipped with special attachments for mowing grass, can you make the right choice. The main technical parameters of such agricultural machinery are:
- Maximum speed (in second gear): 6.9 km/h.
- Operating speed: 2.5 km/h.
- Productivity: 0.3 Ha/h.
- Engine type: single cylinder, two stroke.
- Engine displacement: 218 cm3
- Engine power: 5 l. With.
The mower's tank capacity is only 5 liters, but given the small engine power, there is enough fuel to perform a large amount of work without refueling.
Engine
The MF 70 mower is equipped with a KAWA 178F two-stroke engine, which is lighter compared to a four-stroke product. The use of such a device makes it possible to reduce the weight of the equipment and thereby compensate for the relatively higher fuel consumption when using a power unit of this type. Also, for the normal operation of such a device, it will be necessary to add special types of oil to gasoline to lubricate the crank mechanism and the cylinder-piston group. To prepare the fuel mixture, you must adhere to the ratio of 1/40.
Power 5 l. With. quite enough for processing areas even with complex terrain (slopes up to 25 degrees inclusive). Despite the relatively modest performance, the engines of this model have a long service life, and repairs to the power unit can be done with your own hands. Maximum engine power can only be achieved at speeds of about 3500 rpm.
The mower runs on gasoline fuel
Dimensions
The overall dimensions of the device will be especially important when placing the unit for storage, as well as when mowing in small areas. The presence of fruit or ornamental trees on the site can also become a serious obstacle to work if the dimensions of the equipment are too large. The mower of this model has the following dimensional characteristics:
- Width: 1400 mm.
- Length: 1750 mm.
Thus, having a width of only about one and a half meters, the mower of this model can easily move between the rows of bushes and trees, of course, provided that there is not a large amount of growth in the grass that the cutting part of the device is not capable of mowing.
Fuel consumption
To maximize the service life of your mower, you must use only high-quality fuel. Its consumption will also depend on the type of fuel, because if you fill the gas tank with raw fuel, you will need much more of it to complete a standard amount of work than high-quality gasoline.
Fuel consumption also depends on other indicators. For example, an engine with a worn cylinder-piston group will consume significantly more gasoline than a new unit. If high-quality fuel is used and the mower is operated with a working power unit, then a consumption of about 2 liters per hour is considered normal for this engine model.
