In the following week, the trial production work progressed quite smoothly. After all, compared with the Dongfanghong series in the previous factory, the small tractor is much less difficult in all aspects, and the processing of various metal structural parts is no problem. In particular, Yang Zhi has directly adopted the mature experience of the current Dongfanghong series in accordance with the thinking of later generations, and followed its classic design. After all, although there are differences in body size, material designation, power configuration, etc., the design principle and overall structure are similar. It can basically be regarded as a miniature version of the current Dongfanghong series.

A little more troublesome is the engine. Yituo's own engine factory has never produced such small diesel engines, and if it is purchased, Jinyang Diesel Engine Factory has small engine products. But let's not talk about whether the model matches, it is still only in the trial production stage, the purchase volume is very small, and other manufacturers may not supply it. However, Yang Zhi directly adopted the safest and most secure method - to reduce the cylinder of the engine used in the Dongfanghong series. Although this was just a common move in the previous life, you must know that whether it is the luxury brand BMW, Mercedes-Benz and Audi, or the ordinary brand Toyota, GM, Volkswagen, under a series, many engines are reduced or expanded cylinder displacement and some technologies and components are added or removed.

But now it's 85 years, which is a bit shocking! At this time, most of the domestic manufacturers do not have the idea of serialization and modularization. As soon as it encounters new needs, it will be habitually redeveloped according to the indicators, not to mention the long time, and the risk is not small! Yan Xiaoming, who was distressed, of course knew the goods, and seeing that he could do it in such a time-saving and labor-saving way, he suddenly admired Yang Zhi so much that he threw himself into the ground.

The 45 diesel engine used in the Dongfanghong 40 tractor has a displacement of 3.6 liters, adopts a vertical, water-cooled and four-stroke design, and is a mature product that has been produced for more than ten years. The technology is not advanced, of course, but it is better than the durability of the leather. On this basis, the cylinder was reduced to 2 cylinders, the bore and stroke remained the same, and the other basic design remained unchanged. The rated power is 17KW.

Such an engine not only meets the requirements of small tractors in terms of performance, but more importantly, it is in line with the products of the current engine branch, with a high yield rate and a minimum cost.

Less than two weeks later, a day before the meeting of the new product development leadership group in the factory, a prototype of a small tractor was manufactured. Because it is a trial production, it is mainly to verify whether the overall performance and reliability meet the design requirements. Some details and overall workmanship are not particularly beautiful. After all, in order to save time and reduce expenses, many things are not re-produced, but are made from local materials and directly modified on the basis of Dongfanghong components. But in any case, two weeks of hard work finally came to fruition, Kuang Ping, Tang Xiaozhou, and Li Yang were excited, and even Yan Xiaoming and Zhou Dake, who were relatively calm and calm, were also full of joy in their eyes. Needless to say, the excitement of Wu Yanli, who was already lively, Chen Weiguo, who jumped up and down, also boasted about his achievements when he met people. Looking at these, Yang Zhi was also full of relief.

The next day, the leading group held a meeting directly at the car inspection site, and everyone came to the site to observe the test situation of the newly loaded car. As one of the core blocks, the car inspection yard occupies a considerable part of the area at the rear of the factory. Every new tractor that rolls off the assembly line is field-tested here to ensure proper operation. A large flat area next to it is densely packed with tractors. It turns out that as long as the products that pass the test are parked here. I saw that thousands of Dongfanghong tractors were neatly parked in rows and columns, and the body following the Soviet-style design was majestic and majestic. Being infected, also out of professional habits, Yang Zhi couldn't help but walk up and want to knock on these machines. Hey? When you take a closer look, you can see that there are indeed many traces on the majestic body from a distance, and even the paint is peeling off in some places! How can a new car be so dilapidated? Yang Zhi frowned. At this time, Wu Yanli's shout came from there: "Yang Zhi, come here." It's time to get started! Hearing this, Yang Zhi had to temporarily put aside his doubts. When I got closer, it turned out that the leaders had arrived, and the test master also drove the trial-mounted small tractor over and prepared to start the test. "Brother Zhi'er, what are you doing with those inventory goods at this time?" Chen Weiguo came over awkwardly. It turned out to be a stock car!? Now, Yang Zhi probably knows what happened just now.

At this time, the test installation machine Qì has already driven into the parking lot and started the test run. Yang Zhi could only let go of what he was thinking about first and pay full attention. I saw a small tractor carrying goods along the flat land, slopes, gravel roads and small ditches, and after running two laps, it stopped smoothly in front of the viewer. The test master got out of the car, and wanted to describe the feelings and specific situation of the test to the people present: "This new car is good, the uphill is vigorous, the driving is relatively stable, and the noise and vibration are not too big" Hearing the approval of the test master, the young people who developed new products were naturally very satisfied, and the factory leaders also nodded frequently. Knowing that he was going to demonstrate in front of the leader, the test site naturally sent an experienced master Huang. You must know that Master Huang is over 60 years old and has been responsible for testing since the construction of the factory. In decades of conscientious work, these hands don't know how many tractors they have touched, whatever model you have, drive it in his old man's hands, and you can touch it clearly whether it is good or not!

For this old man, whether it is character or technology, the factory is well-known. The old man is also a national model worker, with deep qualifications, and has received an audience from the founding president and the prime minister. His recognition is tantamount to setting the tone for this new product. It was Liu Yajun, the deputy director of production who was resistant to small tractors, who was ready to pick and choose, but he had to give up when he heard the words.

Naturally, everyone was happy with the test. "The test results are good, which shows that the decision of the factory is very correct. Under the strong leadership of the party committee of the factory, with the efforts of all young workers, our new products have a smooth start, and I hope you will make persistent efforts and continue to carry forward the style! When the small tractor project is a complete success, the factory celebrates everyone! Chen Deshan, who has always been strict, also gave full affirmation. Yang Zhi is not too surprised, after all, there is a tow production and processing foundation, plus so many professionals to join, the risk of small tractors with low technical content is naturally not large. "This new car is good, the uphill is vigorous, the driving is relatively stable, and although the cab is open, the noise and vibration are not too big" recalled Master Huang's words, although he was more recognized, why was he inexplicably a little worried.

As soon as he entered the office of the technical department separately from the factory leaders, Chen Weiguo immediately restored the prototype: "Don't pretend to be deep!" I've been tired for more than a week, how about we go dancing in the evening? "In this era, when disco was first introduced to China and became popular, his mention was immediately approved by several people." Wrong! Yang Zhi screamed, waking up Wu Yanli and the others who were discussing the evening arrangement, and the little girl was a little unhappy: "Yang Zhi, don't be surprised if you don't agree!" ”

Ignoring Wu Yanli, Yang Zhi instructed: "Weiguo, there is still some time before getting off work, you hurry up to the workshop to get the information for this period, and then go to the finance department to bring our expenditure report for this period of time." Suddenly, he was a little confused when he heard the words, but Chen Weiguo had always been very convinced by Yang Zhi, so he went without saying a word. Letting Chen Weiguo go to Yang Zhi was also considered, after all, there was only a little more than an hour before getting off work. Where to delay for a while in the middle, it will be too late today. And those numbers Yang Zhi must get today, let Chen Weiguo, the son of the factory director, go, and the time loss in this regard can be minimized. After all, everyone has to give some face, and Chen Weiguo's self-cooked personality is also quite open.

"Let's get busy with ourselves first, I'll make sure of something, and we'll add it up later." Let the so-called few people return to their respective positions first, Yang Zhi once again confirmed his worries. It turned out that in the impression of the previous life, small tractors were driving slowly on the road, making loud noises and crackling, and the vibration seemed to be not small. But just now, Master Huang said that "the driving is stable, and the noise and vibration are not big", which is very inconsistent. Therefore, Yang Zhicai always felt a little weird. However, you have to see the report to be sure.

After about half an hour, a humming sound approached. Yang Zhi knew that Chen Weiguo was back, this guy was really fast! When he got the list of materials and the cost settlement table for trial production during this time, Yang Zhi sighed in his heart! I saw that the total cost was written: 1200 yuan!

You know, in the mid-80s, the average person's monthly income was less than 10 yuan. For example, the average worker in the factory is about 5-9 yuan, and the working experience is longer, and the overtime is about 10 yuan. Yang Zhi is a college student, and his salary is relatively high, and he is in the factory, and he is only 12 yuan a month. And this 1,200 yuan is to remove some waste and detours in the trial production process, and the actual cost is at least seven or eight hundred yuan, which is the total income of ordinary people who do not eat or drink for 6 or 7 years!

And that's just the cost of materials. In addition to this, the total cost of a commodity also includes transportation, as well as various intermediate links, as well as the necessary profit. If you count all of these, even if Yang Zhi is not very clear about the price of other products, for Yang Zhi's positioning of the product, this price is definitely too high!

At this time, Yang Zhi finally confirmed his suspicions. The test car is really good in terms of noise and vibration, but at the cost of a significant increase in cost. After all, this tractor is used for transportation and production, and at this time, the comfort is far from being considered, but the cost of purchase is real!

Yang Zhi told the big guy about this, and the young people who were originally happy were stunned!
