The sample of the small agricultural walk-behind tractor has been manufactured, and Lin Cheng took Mao Xiaoli and other sales staff to the R&D laboratory with great interest to see the sample of the small agricultural walk-behind tractor.

"Han Ke, Mr. Kobayashi is here!" Xiao Li, a staff member of the technical department, saw Lin Cheng and others coming over, and immediately ran into the R&D room to report to Han Jianjun, the head of the R&D section.

"What, what are you talking about?" Han Jianjun was studying how to reduce the manufacturing cost of walk-behind tractors, but he didn't hear Xiao Li's words clearly.

"Han Ke, it's Mr. Kobayashi, Mr. Kolin has come to inspect our technical department. Xiao Li Miao stepped forward and said loudly.

"Oh, why didn't you say it earlier, hurry up and clean up!" Han Jianjun said anxiously.

At this moment, Lin Cheng's voice had already come in: "Don't bother, I'll take a look at the sample of the tractor, and I'll leave after reading it, I won't disturb you." ”

As soon as the tractor was mentioned, Han Jianjun's spiritual head came, he didn't even care about wiping his hands stained with diesel, took Lin Cheng's hand, and said: "Mr. Xiaolin, you came just in time, this small agricultural walk-behind tractor you designed is very easy to use, it is simply a lucky star for farmers and friends, and they will not need to plough cattle in the future." ”

As he spoke, Han Jianjun stood in front of the tractor's operating position, holding the handles on both sides of the tractor with both hands, simulating the operation action.

Seeing Han Jianjun constantly playing with the tractor like an old naughty boy, Lin Cheng also became interested, and went here to touch where to pinch, pretending to be an agricultural machinery expert, in fact, in addition to knowing a little bit of the structure and principle of the tractor, he knew all the other tricks, and he didn't know anything.

Han Jianjun thought that Lin Cheng was an expert, and once again took Lin Cheng's hand and said: "The walk-behind tractor is composed of an engine, a transmission system, a braking system, a walking system, electrical equipment, and a working device. We can simply divide it into two parts: engine and chassis. Don't look at its many parts, faults can be found by listening, seeing, smelling, and touching. ”

"I'll take a look. Lin Cheng followed Han Jianjun's instructions, conducted a detailed inspection of the major components of the tractor, and then pondered for a long time, and said: "The traditional walk-behind tractor has several difficulties that are very worthy of our attention, especially the shortcomings of the tractor starting difficulty, we must improve, especially the ambient temperature is too low, diesel problems, oil circuits, improper engine adjustment, low cylinder pressure will make it difficult for the machine to start, we must study these problems in a targeted manner." ”

"Secondly, the smoke exhaust problem of the engine, when the mixed gas in the engine can not be completely burned, a large amount of black smoke will be discharged, which is toxic gas and can easily pollute the environment, so we must control it. If the whole sky is dark after the farmers use our agricultural machinery, and people often get sick, then they might as well continue to use the cattle, and in the long run, it is easy for the environmental protection bureau to catch the handle. ”

"In addition, the engine overheating, insufficient oil pressure, difficult gearing, steering misalignment, brake misalignment and other tractor problems that are prone to occur we must pay attention to, in the design and production process, we must work hard to practice, in order to produce a good product that farmers can trust. ”

"That's great!" Han Jianjun slapped his thigh, then turned to Xiao Li and said: "I'll just say, Lin is always the designer of small agricultural walk-behind tractors, how can he not know how to do it, just a few words to point out all the problems that this machine is prone to, if our technical department can come up with a way to solve these problems, I am afraid that farmers and friends will not compete to buy our products!"

Lin Cheng was secretly refreshed when he heard this, but he said modestly: "Don't, don't say that, I'm just a Zhao Kuo on paper, and the specific work has to rely on you to do it." ”

"Mr. Lin, you are so modest!" Although Han Jianjun is a technical nerd, he can be regarded as self-taught for sycophants.

"By the way, how many of these products have been made, can you go to the cultivated land to test it?" Lin Cheng asked.

"There are three units, and there is a one-acre test field behind our factory, where you can try it. Han Jianjun said.

"Then let's go there and try it, practice will make you real!" Lin Cheng said with a smile.

"Okay, just listen to Mr. Lin. Han Jianjun responded.

……

The factory wants to test new products, and the middle and senior leaders who learned the news have come to see the excitement, after all, the success or failure of this new product determines whether the new machinery factory can be reborn, and it is a matter of great importance.

In order to more intuitively reflect the advanced nature of agricultural walk-behind tractors, Han Jianjun did not know where to find a middle-aged farmer and a ploughing ox, and divided a rice field into two parts.

Lin Cheng's interest was very high, and he volunteered to be the referee, he brought a stopwatch to time, pressed the button and shouted: "Ready, start!"

The "boom ......" tractor began to warm up, and the middle-aged farmer skillfully waved his whip and drove the plough oxen to plow the ground.

At the beginning, the middle-aged farmer was an old crop handle, and he was very skilled in plowing, and he quickly pulled away a distance, while Xiao Li was not familiar with the performance of the machine at all because he was driving a tractor for the first time. As a result, Xiao Li became more and more flustered under the gaze of everyone, and drove the tractor directly into the ground.

Han Jianjun's face turned a little dark, and he hurriedly ran forward to help pull the machine up, while the leaders who were watching the excitement next to him also had ugly faces and started talking about the machine.

"It's over! What kind of broken machine did the technical department make? It stopped cooking as soon as it started!"

"Shh......h , your voice is quieter, I heard that this machine was designed by Mr. Kobayashi himself!"

"We all know that Mr. Kobayashi has no hair and can't do things well, but how can the people from the technical department play with him?

"This ......"

Of course, Lin Cheng also heard these discussions, but he had been sitting firmly in Diaoyutai and turned a deaf ear to these criticisms.

At this point, everyone decided that the tractor was going to lose the race, because after a few minutes had passed, the middle-aged farmer had already turned around, and the tractor had just started again.

However, as the game continued, everyone was dumbfounded, and after Xiao Li was familiar with the performance of the machine, the tractor actually caught up in just a few minutes.

In the end, it only took Xiao Li 20 minutes to drive a tractor to plow half an acre of land, while the middle-aged farmer took a full hour to plow the land.

It is clear which is better and which is inferior.
