To the east of the town is a vast plain, which has now been reclaimed and turned into a continuous stretch of farmland. At this time, it is very lively, surrounded by people, and various machinery and vehicles are placed.

Today is the day of the acceptance of several newly developed vehicles and machinery of the Far Eastern Automobile Plant, where a group of members of the Standing Committee and members of the Board of Directors, as well as the heads of various departments and enterprises in Vladivostok, have gathered.

Several tractors and farm vehicles were dressed in red and green, and colorful flags were fluttering around, and the atmosphere was extremely enthusiastic.

After a short ceremony, today's acceptance work began. First of all, several walk-behind tractors, equipped with 15 horsepower and 18 horsepower single-cylinder diesel engines, drove "suddenly".

And there are several types of agricultural machinery hanging on this cultivated land to carry out various farming activities. These walk-behind tractors are mature brands that imitate modern society. Walking tractor is a kind of transportation and agricultural machinery popular in Chinese towns and villages, powered by diesel engines, and its small, flexible and powerful characteristics make it very popular with farmers.

The walk-behind tractor has the advantages of light weight, small model, flexible operation and strong adaptability, with different agricultural machinery, it can carry out a variety of field operations such as ploughing, rotary tillage, leveling, crushing soil, etc., with trailers, it can also be transported for short distances, and it is definitely an all-rounder in rural areas in the future.

This was followed by a demonstration of an agricultural tricycle powered by a 20 hp single-cylinder diesel engine. Agricultural tricycles are also a versatile means of transportation in rural areas. It not only has the advantages of simple operation, convenient maintenance, large load capacity, etc., but also has a wide range of application, and is an ideal means of transportation for grassroots villages with complex road environment, and has small requirements for road conditions.

This time, the Far Eastern Automobile Manufacturing Company developed a total of two tricycles. One is a normal cargo type, and the other is a dump type. It can not only be widely used in the fields of grassroots rural areas, but also can be used as a foundation in various places with difficult conditions and complex terrain

Finally, there is a small four-wheel tractor, using a 20-horsepower single-cylinder diesel engine, the prototype of which is an imitation of the Dongfanghong 180 small four-wheel tractor. Has a simple structure. It has the advantages of good work performance, high production efficiency and wide use.

Moreover, the traction is greater, the operation grade is more, and the climbing ability of mountain roads is strong. It is especially suitable for transportation operations in rural areas, and can also effectively carry out various field operations, including cultivated land, harrowing, rotary tillage, sowing, harvesting, field management, etc., as well as pumping, sprinkler irrigation, power generation, flour grinding, rice milling and other fixed operations, and can also meet the requirements of mechanized operations in plains, hills, pastoral areas, vegetable gardens and orchards.

In the future, Far Eastern Company will vigorously promote the popularization of walk-behind tractors, small four-wheeled tractors and agricultural tricycles in Far Eastern Company. The productivity of the Far East Company in all aspects of its work will be greatly improved.

The members of the Standing Committee of the Board of Directors were very interested in several types of tractors, which, judging by the current situation, were the most suitable for the Far Eastern Company. After all, the company's grassroots villages, infrastructure construction sites, mines and highway and railway construction sites are in urgent need of some mechanical vehicles that are convenient to maintain, simple to operate, and can be used in various complex road conditions.

Before the start of the acceptance work, the Far East Power Research Institute and the Far East Automobile Factory had already carried out a large number of tests on several tractors and agricultural vehicles, covering a range of thousands of kilometers, including tests on various complex road surfaces, harsh winter climates and complex weather conditions such as wind, snow, rain and fog.

The results of the test are very encouraging. The performance data not only met the design requirements, but also performed very steadily during the testing process. The Far East Power Research Institute and the Far East Automobile Factory are very reassured.

Now comes the highlight of the day, with two large steam-powered tractors about to begin testing. These two steam engines are 65 horsepower and 110 horsepower respectively, which can also be called large tractors.

Moreover, the tractor with a 110-horsepower steam unit is also divided into two types: wheeled and tracked. The 110-horsepower tractor is nearly five meters tall and more than three meters high, and looks like a small steam locomotive. There is also a high punishment, and there is a huge flywheel on the right side of the body. It made a huge roar and smoke, and those who didn't know it thought it was a train coming from a distance.

Wheeled tractors have wide iron wheels with a patterned rubber layer attached to the surface. Able to travel in a variety of road conditions. The horsepower is extremely strong, except for the slower speed, the other performance is very good. And it can mount a variety of agricultural machinery and construction machinery, and can undertake a variety of jobs. Crawler tractor, suitable for any road conditions to travel, walking on the cultivated land is extremely powerful and domineering.

Each steam tractor requires three or four people to drive, and the operation is a little cumbersome, and the speed is relatively slow, but the horsepower is strong, and the driving is very powerful. The steam tractor can not only tow a variety of agricultural machinery for farming in the vast fields, but also can haul cargo boxes as transport vehicles to carry large goods.

Moreover, the company's power research institute has also set up supporting external equipment on each steam tractor to act as a workstation for power stations, water pumps, sprinkler irrigation, flour grinding, rice milling and other activities. It can also be connected to various mechanical equipment as a power platform for various machinery.

The thermal efficiency of steam locomotive is very low, only part of the heat of fuel combustion in the boiler is converted into the heat energy of steam, and the efficiency of the boiler is generally 50%~80%. Steam works in the steam turbine, and the efficiency of the steam turbine is only 10%~15%. Therefore, the maximum thermal efficiency of steam locomotive is only 8%~9%. Moreover, it still consumes fuel when parking at the station, maintaining and staying in the locomotive depot, so the actual thermal efficiency is only 5%~7%.

But it is undeniable that there are a lot of steam engines, which are not only easy to operate and maintain, but also do not require high fuel, coal or wood can be used as fuel, and almost all fuel can be used to convert thermal energy into mechanical energy. The steam engine is also very suitable for high altitudes, and can still operate normally under low air pressure.

Before the development of the company's high-horsepower internal combustion engine, the high-horsepower steam engine will also be easy to popularize and promote in large quantities because of its low technical content, and will make great contributions to the construction of the Far East Company in all aspects in this special period.

"Tutu...... Sudden ......"

With a roar, several large steam-powered tractors roared out, and the thick smoke instantly filled the sky, like several steam locomotives driving off the tracks and running across the vast plains. (To be continued.) )
