General information
The Patriot brand originally originated in America, and not in Russia, as it might seem at first glance. Later, walk-behind tractors under this brand began to be produced in China. Cheap labor in this country has significantly reduced the cost of the model. But at the same time, production is under the complete control of American specialists. Moreover, the Chinese Ural assembly plant meets all international standards. Many modifications allow you to choose the best option depending on the customer’s needs.
The Patriot Ural walk-behind tractor is considered more expensive than its Russian counterparts. The model range of the American brand is extensive and diverse, and in terms of reliability, Patriot products are in many ways superior to domestic models, which is an undeniable competitive advantage. The Patriot Ural technology has existed in Russia for quite a long time, and is among the most popular.

Ural ZID-4.5
This engine does not have any special distinctive technical characteristics from the UMZ 5V. The only thing is that it is capable of carrying out work on AI-72 fuel, but this affects the performance characteristics of the Ural walk-behind tractor.
A large amount of carbon begins to form on the cylinders and spark plugs, and the speed stability and overall power decrease.
Ural ZID 4.5 was produced as an experimental model, which did not find widespread use.
Ural with Chinese engines
Recently, Chinese engines for small garden equipment have become increasingly popular. They are distinguished by high technical characteristics, low cost and excellent quality.
The most popular manufacturer of such devices is Lifan, which is considered an analogue of the world famous Honda. At the same time, it costs several times less. There are a large number of videos on the forums about the process of engine conversion.
Purpose and design features
Patriot Ural is a durable device designed for processing soil of any complexity. The equipment is also suitable for transporting goods over short distances. The reinforced frame provides superior off-road capabilities. In addition to the frame, the design of the device may include additional attachments.
- The reinforced frame can serve as a handle for convenient movement of the walk-behind tractor. The frame also protects the motor in the event of a rollover. The main frame has several holes to which a “hitch” is attached, driven by a drive pulley. This equipment has the ability to bend in order to protect it from scratches and other external influences.
- Additional frame - located under the bottom of the engine compartment. By design, this is a simple technical addition, but it plays a very important role in terms of increasing functionality. The frame is so strong that it will support various containers and boxes, and at the same time protect the motor from collisions and shocks. For greater reliability, an additional frame is attached to the main frame and control handle.
- The walk-behind tractor is equipped with a three-speed gearbox and a belt clutch. The gearbox is made in a cast iron housing, which is very resistant to increased loads. Also, the cast iron construction avoids various leaks. The gearbox is convenient to operate due to the fact that its lever is located towards the operator.
- If necessary, you can remove the fenders and mudguards that trap clods of earth.
- The list of equipment includes a powerful headlight with effective lighting regardless of the time of day.
- Cross-country ability is improved by pneumatic wheels. Their impressive dimensions give confidence when overcoming bumps, bumps and other off-road elements.
- The design of the device includes a separate lubrication system. This means that there is no need to mix fuel and oil when filling. In addition, this system increases torque. The basic version of the walk-behind tractor includes tillage cutters, an S-shaped coulter, a bracket, discs and pneumatic wheels.
Ural with UMZ-5V engine
The engine of the Ural UMZ-5V walk-behind tractor is a 4-stroke, 1-cylinder gasoline unit with a volume of 475 cm³. The motor was originally created for use on self-propelled agricultural machinery and stationary installations. The power unit develops a power of 4.5 liters. With. at 2000 rpm. The plant allows a short-term increase in power up to 5 hp. With. by increasing the speed.
Long-term operation at high power is not allowed, as it leads to overheating.
The engine is equipped with an air cooling system. To cool the engine, a fan is used that forces air into a casing located around the cylinder and head. When operating a walk-behind tractor, it is necessary to regularly inspect and clean the cooling fins from dust and oil. Accumulated dust impairs heat transfer and causes local overheating, which leads to increased engine wear.
The motor is equipped with an automatic speed controller. For this, a centrifugal mechanism is used, which does not allow a rotation speed of more than 2350 rpm. When the speed is exceeded, the throttle valve shifts, which leads to a drop in rotation speed. The engine manufacturer prohibits self-adjustment of the rev limiter, as well as its use to control the speed.
The gas distribution system consists of 2 lower valves. Because of this, the engine has a low compression ratio of 6 units. The engine uses automobile gasoline A-76 (A-80) as fuel. The fuel supply is located in a tank located above the engine carburetor; the liquid is supplied by gravity. The fuel reserve in the tank is 6 liters, which provides an operating time of up to 4-4.5 hours. Operating time depends on the condition of the engine and the nature of the tasks performed.
The engine of the Ural walk-behind tractor is equipped with a 2-speed gearbox with reduction gears. The first speed reduces the rotation speed by 6 times and is used to perform work with a high coefficient of resistance (for example, plowing virgin soil). The second speed reduces the speed by 2.91 times and is used for operating the product with a trailer or when plowing soft soil. Switching the speeds of the UMB-K Ural walk-behind tractor according to the instructions is carried out with the engine not running.
The engine is started with a cord that is wound around the flywheel. Before starting, it is necessary to set the crankshaft to the compression end position. Starting the engine is permitted in 1st or 2nd gear of the motor gearbox.
The engine output shaft is equipped with a 2-ribbed pulley designed to transmit torque to an additional gearbox and to drive attachments. On the fan side there is a second pulley used to drive attachments that require increased rotation speed of the working parts. The clutch mechanism consists of belts and tension rollers.
According to the repair instructions, the transmission crankcase of a walk-behind tractor with a UMZ-5V engine is filled with 1.5 liters of transmission oil. The substance is poured through a hole closed with a plastic stopper.
The standard set of attachments for the walk-behind tractor included a cultivator. To transport cargo weighing up to 350 kg, a 2-wheel TOP-350/350M trolley was used. When using a single-body plow, the installation of an adapter device is required, which is attached to the frame. The plow can be used in conjunction with metal wheels equipped with lugs. A mounted potato digger is used in conjunction with a plow.
Engine
Patriot Ural is offered with a single 4-stroke engine. The engine, called Patriot Garden, has a good margin of safety, despite the fact that it is assembled in China.
The engine supports 92 gasoline and does not require additional lubrication. Patriot Garden has a displacement of 220 cubic meters and a power of 7.8 horsepower. The unit is single-cylinder, with a tank capacity of 3.6 liters.
Operating and maintenance instructions
With proper operation and maintenance of the equipment, it can operate for a long period. The operating instructions are as follows:
- Equipment is assembled and installed, all elements are connected.
- Engines are supplied dry. This moment determines that you need to purchase a suitable lubricant and pour it into the structure. Some models work with a fuel mixture that includes oil.
- The first start must be done carefully. To do this, select idle mode, the engine warms up for several minutes.
- After working for the first 20 minutes, it is recommended to drain the old oil, after which new oil is added. This is due to the fact that at the time of grinding in the main elements, metal shavings may get into the lubricant.
- For the first few hours, it is recommended to use the cultivator at 2/3 power. This will eliminate the possibility of various malfunctions.
- At first, it is recommended to monitor the engine temperature, because... there is a possibility of it overheating.
- If the engine is unstable, you need to stop the walk-behind tractor and then find the cause of the problem.
- After operating the equipment, the surface should be cleaned of various contaminants. In addition, the condition of all main elements is checked, because further operation with malfunctions is not allowed.
Maintenance includes timely oil changes. In this case, you need to periodically add lubricant to the gearbox.

Owner reviews
- Alexander, St. Petersburg. I've been using it for three years, no problems. I actively use it for plowing and hilling. The model is powerful enough for my needs. Good maneuverability is ensured by reverse, and it is also more convenient to work with in difficult areas. I bought a mower and hiller, the functionality has increased several times. Average fuel consumption is around 2 liters per hour, at maximum load it reaches 3 liters.
- Alexey, Krasnodar region. Patriot Ural is a very good walk-behind tractor, but not without sin. It has a well-thought-out design, and at the same time, noticeable flaws. For example, I almost immediately noticed play in the control handle. The frame is welded unevenly, and besides, poor fastenings spoil the impression. Well done Chinese, they found something to save on. Despite the assembly flaws, the equipment drives and works normally. Consumes no more than 2 liters per hour.
- Pavel, Stavropol region. It’s a good walk-behind tractor; it will come in handy for plowing and harvesting. I have 20 acres, but the Urals have plenty of potential. I'm still happy with the car, after a year of intensive use.
- David, Yaroslavl. I love the American auto industry, including the Dodge Nitro itself. Patriot Ural is as reliable as my SUV. I bought an additional trailer, hiller and plow for it.
- Dmitry, Kaliningrad. My Patriot is much better than its Russian counterparts. It not only has an attractive design, but also high performance. The machine is very beautiful, and the power is quite satisfactory - a medium-power walk-behind tractor is enough for me. I didn’t even consider diesel options, since in Russia there are problems with the quality of this fuel. Over the past two years of use, the equipment has shown itself to be great. I replaced the clutch disc without having to call a technician. I will even say that this walk-behind tractor is like a construction set - it is easy to assemble and disassemble. It must be admitted that the Patriot Ural is noticeably more expensive than Chinese cars, although it is assembled in China, but using American technology. But I don’t pay attention to the assembly location; for me the main thing is functionality and reliability.
- Yuri, St. Petersburg. Overall I liked the walk-behind tractor, with the exception of some quibbles. For example, I would like to note that spare parts are quite expensive compared to their Chinese and Russian counterparts. But at the same time, the walk-behind tractor is famous for its greater endurance. After three years of operation, the clutch began to work every now and then - it turned out that this was due to a jammed handle. Otherwise, everything is normal, consumption is at the level of 2-2.5 liters.
Motoblock "Ural"
Motoblocks "Ural-UMP-5V" first began to be sold in the country just before its global redistribution at the dawn of the 90s of the last century. Since many people needed walk-behind tractors as a convenient and cheap technical tool, it became very popular in the USSR. In just a few years, its sales reached 150 thousand units. The optimal combination of its characteristics contributed to the popularity of the walk-behind tractor.
The developers were able to combine the high performance of the walk-behind tractor, which was achieved by a five-horsepower gasoline unit that accelerates it to a speed of 15 km/h, combined with battery power sufficient to cultivate up to 2 hectares of arable territory. In addition, the unit could transport cargo weighing up to half a ton.
The walk-behind tractor has a wide adjustable ground clearance, which allows the device to be used in different types of areas. But it is worth noting that the basic Ural model is not particularly multifunctional. It can only transport cargo and cultivate the soil. It will not be possible to mow grass, remove debris or snow using attachments with this type of equipment - such capabilities are not provided. But if you remake the design yourself, adding the necessary fastening units, you can expand its functionality.
