For cultivating land in small areas, it is good to use lightweight motor blocks. One of the great options is the Plowman MZR-820. This device is capable of processing up to 20 acres of soft soil. Consider its features in more detail.
The manufacturer advises in conjunction with a walk-behind tractor to apply:
- hooks for soil;
- potato digger;
In some cases, the use of snow blowers, dump shovels and rotary mowers is allowed. By default, the Plowman 820 walk-behind tractor is equipped with a four-stroke Lifan 170F motor. This device has proven itself on many other agricultural machines. The total power of the power unit reaches 7 liters. with. At the same time, he makes up to 3600 revolutions per minute. The capacity of the gasoline tank reaches 3.6 liters.
The motor-block petrol TCP820PH is unsuitable for industrial agriculture. It is much better suited for manual processing of private gardens and gardens. In this case, the functionality of the technique is quite sufficient. The cast iron chain gear guarantees long-term operation even in harsh conditions.
Other characteristics are as follows:
- starting with a manual starter;
- Belt drive
- varying the depth of tillage from 15 to 30 cm;
- processing strip from 80 to 100 cm;
- a pair of front and one reverse gear;
- compatibility with hinged systems from "Cascade", "Neva" and "Oka".
Since the “Plowman 820” is very noisy (the sound volume reaches 92 dB), it is not recommended to work without an ear plug or special headphones. Due to strong vibration, protective gloves must be used. Every year you should contact the service center to carry out maintenance. It is advisable to pour AI92 gasoline into the engine. The gearbox is lubricated with 80W-90 brand gear oil.
Given the requirements of the assembly instructions, the first start-up is carried out, completely filling the tank with fuel. Also completely pour oil into the motor and into the gearbox. First, the walk-behind tractor must work at least 15 minutes in idle mode. Only after warming up they start work. Break-in duration is 8 hours. At this time, it is unacceptable to increase the load of more than 2/3 of the maximum level.
The oil used in the break-in is poured. Before the next launch, you will need to pour in a new portion. Systematic maintenance is carried out after 50 hours. Check for mechanical damage. Be sure to clean the fuel and oil filters.
Consumers consider this walk-behind tractor not only easy, but also convenient to drive. The launch is as quick as possible. Failures of starters are extremely rare. Engines can confidently work for at least 4 years. However, the instruction will have to be read thoughtfully, because often it is written very vaguely and unclear.
Motoblock rides pretty fast. "Plowman" has a reverse mode and consumes exactly as much gasoline as indicated in the description. Hard land cultivation presents some difficulties. The device moves on dense ground very slowly. Sometimes you have to go through each lane twice to process it as efficiently as possible.
How to make the device heavier?
To partially solve the above problem, you can weight the walk-behind tractor. Self-made weighting materials are no worse than those made at the factory.
Weighting is especially relevant:
- when working on virgin soil;
- when you need to climb a slope;
- if the ground is saturated with moisture, causing the wheels to slip very much.
It is important to remember: any weighting materials should be mounted so that they can be easily removed. The easiest way is to increase the weight of the walk-behind tractor by adding loads to the wheels. It is most beneficial to make cargo from steel barrels. First, the billet is cut into 3 parts with a grinder so that the height of the bottom and top is from 10 to 15 cm. Steel strips are used to strengthen the welds.
After this, the workpiece must be drilled through 4 or 6 times through so that the bolts can be screwed in. In some cases, steel washers are added, reinforcing the structure. Bolts should be selected more authentically, then fixing empty tanks on the discs will be simple. After installation, sand, crushed granite or brick chips are poured into the tanks. To make the filler denser, it is abundantly moistened.
Disassembled steel weights can also be used. They are prepared from hexagonal rods, the size of which allows you to easily enter the workpiece into the opening of the chassis of the walk-behind tractor. Having cut off a couple of short pieces from the profile, they are welded to the disks for the gymnastic bar. The axis and profile are drilled through to drive the cotter pins. You can further increase the weight of the walk-behind tractor by welding pancakes from the bar to the plates.
Sometimes these kinds of supplements look ugly. It is possible to improve the appearance by welding unnecessary clutch baskets from the cars of the Volga automobile plant. These baskets are painted in a random color. Some owners of motoblocks prepare cargo from reinforced concrete. It is poured into the reinforcement cage.
When wheel weights are not enough, weights can be added to:
In these cases, the center of gravity of the walk-behind tractor must be taken into account. Bolts with a cross section of 1.2 cm and a length of at least 10 cm are welded onto the steering wheel bracket. The frame is welded from a corner, then holes for bolts are punched in it. The frame is carefully adjusted to the frame, painted and attached. Cargo must be of appropriate size.
Why is the machine smoking?
Although the appearance of smoke at the Plowman motoblock is a relatively rare occurrence, nevertheless, it should be treated as carefully as possible. The emission of white smoke puffs indicates oversaturation of the fuel mixture with air. Sometimes this may be due to the ingress of water into gasoline. It is also worth checking if there are any oil clogs on the exhaust duct.
What else do you need to know?
Plowman motor-blocks can be operated in any weather conditions that are typical for central Russia. Humidity and precipitation do not play a special role. In the manufacture of a steel frame, reinforced corners are used. They are treated with a substance that inhibits corrosion. Each seam is evaluated on special production equipment, which allows to increase the share of quality products to 100%.
The developers were able to make an excellent cooling system. It blocks piston overheating even at extremely high air temperatures. The transmission housing is strong enough so that the gearbox does not suffer during normal operation. Sophisticated geometry of the wheels reduces the complexity of their cleaning. In the construction of the walk-behind tractor there is also a power removal shaft, which significantly increases the functionality of the device.
Using the unit, it is possible to plow the virgin soil with a single-body plow. If you need to process black soil or lightweight sand, it is recommended to use trailers with 2 or more shares. With "Plowman 820" are compatible both disk, and turnouts. If you use rotary mowing machines, you will be able to mow about 1 ha during daylight hours. Together with this walk-behind tractor, it is advised to use rotary snow blowers.
Having hooked a rake to the Plowman, it will turn out to clear the territory of the site from small debris and old grass. Also, this walk-behind tractor allows you to connect a pump with a capacity of 10 liters per second. It will also serve as a good drive for electric generators generating up to 5 kW. Some owners make "Plowman" the drive of various crushers and artisanal machines. It is also compatible with uniaxial adapters from a number of manufacturers.
