Application scenarios
Fertilizer with Seeder Drill Series (Classes 1-4)
1. Fertilizer with Seeder Drill (Corn Precision Fertilizing Seeder)
1.1 Product Performance: Possesses all the performance characteristics of a Variable Speed Rotary Tiller; can complete, in one pass, tillage, stubble removal, seeding, fertilization, soil covering, and compaction—various cultivation and sowing operations. By replacing different components, it can sow a variety of crops including wheat, corn, soybeans, rice, rapeseed, buckwheat, and highland barley.
Adapts to dry and hard soils, semi-paddy fields, semi-sandy soils across the country; suitable for areas with two harvests per year, one harvest per year, fields with high stubble, fields where straw has been crushed, and can be directly drilled without clogging. It supports no-till seeding, full-tillage seeding, as well as land preparation and seeding following deep plowing.
Can be used with tractors in the 50–180 horsepower range.
Equipment features:
1.2 One machine for multiple uses: a Rotary Tiller, a Seeder, and a Fertilizer Applicator all in one; it can perform both conventional tillage and no-till seeding; it can sow not only wheat and corn but also rapeseed, barley, buckwheat, rice, sorghum, and other crops.
1.3 Possesses all the features of a three-speed Variable Speed Rotary Tiller:
1.4 High Efficiency and Low Consumption: The consumption of the Rotary Tiller and the benefits achieved by the no-till seeder.
The reasonably designed and compact seed-fertilizer applicator is closely fitted to the Rotary Tiller blades. It ingeniously utilizes the vacuum zone created by the Rotary Tiller to apply fertilizer and sow seeds simultaneously. As the soil is thrown up and then falls back down, it naturally covers the seeds without increasing the tractor’s horsepower consumption. Whether you’re pulling a Rotary Tiller or an equally wide rotary seeding and fertilizing machine, fuel consumption remains the same—yet you earn more money while using the same amount of fuel.
1.5 Invention Patent Technology for Wide-Row High-Yield Wheat Sowing: This technology features a sowing strip 12 cm wide per row, with each row equivalent to 3–4 rows in traditional seeders. It addresses the longstanding issue of manual broadcasting, where seeds are scattered indiscriminately without any ventilation strips, leading to poor ventilation and insufficient light exposure. It also resolves the problem with conventional wheat strip-sowing machines—though they do have ventilation strips, the narrow seedbeds result in overcrowded seedlings, further impairing ventilation and light penetration. In the wide-row system, each individual seed occupies a larger area of soil (while the empty spaces remain unchanged), ensuring excellent ventilation and light transmission. As a result, the effective tillering rate of wheat is significantly higher—around 30%—leading to more spikes per plant. Since the 1980s, this technology has been promoted from Shaanxi Province across the entire country. Under comparable conditions, it can increase yield by 10–15% per mu. Starting from 2023, it has been designated as a key promotion product in Shaanxi Province and has been submitted to the Ministry of Agriculture as part of the “Wide-Row Groove Sowing Project” aimed at boosting wheat yields.

Note: The origin of YAAO wide-width broadcasting
The wide-width seeding device is a wide-width seed-metering device developed by YAAO in 1986, based on the rotary seeding and fertilizing machine. In 1982, this machine won the Third Prize for Scientific and Technological Progress at the ministerial level, and in 1987, it received the First Prize for Scientific and Technological Progress from Shaanxi Province. YAAO was the drafting unit of the national standard for rotary seeding machines. In 1988, the machine was awarded the Gold Prize under the Spark Program by the State Ministry of Science and Technology. In 1991, it was presented as a state gift by the former President Yang Shangkun to Mexico—30 units were given as gifts.
1.6 Invention Patent for Anti-Clogging and Weed-Removing Blade: No clogging even with high stubble and thick stalks; precise and meticulous soil preparation ensures high yields. By scientifically harnessing the high-speed rotation (inertia) of the Rotary Tiller—operating at over 360 revolutions per minute—the machine promptly clears weeds from between seed tubes and on the seedbed, whether the corn stalks are standing upright or the fields are covered with wheat straw after harvest. This thoroughly resolves issues related to machinery passability as well as the risk of seedlings being damaged and production being affected due to excessive straw and weed buildup on the seedbed.
1.7 Technical patent for the contour-following system: The unique contour-following depth-limiting system comprises front and rear contour-following wheels, a central pull-rod with slotted holes, and a dual-beam, dual-suspension mechanism. This system completely solves the challenge of inconsistent seeding depths caused by suspended implements and eliminates hydraulic losses in tractors, thereby reducing driver fatigue. Most importantly, it ensures stable and consistent tillage and seeding depths.
1.8 The corn planter is equipped with a new-generation finger-type metering device independently developed by YAAO, featuring high precision and a single-seed sowing pass rate exceeding the national standard by 85%, reaching 95% of the imported standard, and achieving a success rate of 96-99%. Its stable quality and high precision extend the national three-year warranty period to six years. Compared to conventional precision planters on the market, under the same quality conditions, its speed can be increased by more than 60%, rising from 5 kilometers per hour to 8-10 kilometers per hour.
1.9 Species-specific, alternate-row layered fertilization technique: Apply wheat fertilizer at a depth of 5 cm in the center row and corn fertilizer at a depth of 5 cm on the side rows. Compared to the conventional pre-sowing broadcast application method, which has an effective utilization rate of only 30%, this technique achieves a fertilizer-saving rate of over 30%.
1.10 Labyrinth-type weed and dust-proof ring: The weed and dust-proof ring is installed at both ends of the blade shaft to prevent straw, weeds, and dust from damaging the blade shaft and oil seals.
Differences from peers:
1. The rotary seeding and fertilizing machine is an invention of YAAO, the drafting unit of national standards, and the largest domestic manufacturer of combined machinery. Its products can perform both no-till seeding and full-tillage rotary seeding operations; by simply replacing different subassemblies, it can also perform rotary seeding and no-till precision seeding of corn. In contrast, competing products can only perform no-till seeding of wheat or corn, and their row spacing and cutter shaft speed cannot be adjusted.
2. Wide-row wheat seeding yields high productivity, while finger-type precision corn seeders offer high accuracy and excellent efficiency.
3. The compaction unit of our factory adopts a split, detachable structure and operates in single-row compaction mode.
4. Front and rear contour following, with stable seeding depth.
5. Wider (50, 35) plow blades—high strength and 40% longer service life.
6. * Compared with similar products, this machine performs smoothly and efficiently on dry, hard ground, and exhibits excellent passability on wet, sticky terrain. It boosts crop yields by 10–15% and reduces fertilizer use by more than 30%. Operating it can increase net profit by 80–140 yuan per hour. For farmers, it can cut costs and increase income by 170–248 yuan per mu.

In 15 minutes, you can till and sow 1,900 meters with a working width of 2.2 meters. Dividing this by 666 and then multiplying by 60 minutes gives: (1,900 meters × 2.2 meters ÷ 666 ÷ 15 minutes × 60 minutes) = 25 acres per hour. If you work 8 hours a day, you can till and sow 200 acres—compared to the previous 167.5 acres—resulting in an additional 33.3 acres tilled and sown each day. At a rate of 50 yuan per acre, this translates to an extra income of 1,665 yuan per day (or 8 hours). This represents a 19.8% increase in productivity. If you work 10 extra days each year, you’ll till an additional 333 acres, earning an extra 16,650 yuan annually. Over five years (50 days), you’ll till an additional 1,665 acres and earn an extra 83,250 yuan. |
In 18 minutes, 1,900 meters of land are cultivated at a working width of 2.2 meters. Dividing this by 666 and then by 18 minutes, and multiplying by 60 minutes yields: 20.9 acres of land cultivated per hour. Multiplying this hourly rate by 8 hours of work per day gives a total of 167.5 acres cultivated and sown per day. |
Note: Conventional rotary seeders lack front and rear contour-following and anti-entanglement/anti-clogging devices, resulting in a 19.8% lower tillage and seeding efficiency compared to the YAAO model. |

| For wide-row seeding of wheat and rice, use a wide-row spacing of 12 cm. The seeding of wheat and rice is accomplished via a spring-loaded mechanism. The seed board evenly distributes seeds into the soil, forming a 12-cm-wide seed band that enhances soil utilization. Under the premise of use, the wheat empty strip remains unchanged. Taking 2BFG-3/8(20D) as an example: seedbed The sowing area is 12 cm × 8 rows = 96 cm; whereas the comparable product on the market is 3 cm × 12 rows = 36 cm. The YAAO will soon be adjusted to 7 rows (no-till seeding): 12 cm × 7 rows = 84 cm; it's also higher than the same row. The product measures 36 cm, representing 233%. The seeds are not crowded, and each individual seed occupies a large area of soil, resulting in strong seedlings. The width is typically around 12 cm, enabling a rational arrangement of the wheat population structure and enhancing ventilation and light penetration. Achieve high single-seed tillering, thereby saving more than 306 seeds and increasing yield by over 10%. |

| Save 30% on seeds | Sowing rate: 30–50 jin per mu. Based on 30 jin, 30% equals 9 jin. At 2 yuan per jin, 2 yuan × 9 jin = 18 yuan (savings per mu). | Saves 18 yuan per mu in seed costs. Ten mu save 180 yuan in seeds, hundred... Saves 1,800 yuan per mu; for 1,000 mu... Save 18,000 yuan on seeds. |
|
| Increase production by 10%-15% High-yield areas increase production by 10%. Increase production by 15% in low-yield areas. |
Yield per mu ranges from 1,000 to 1,500 jin; taking 1,000 jin as the base, the yield increase is calculated at 10%. Thus, 1,000 × 10% = an additional 100 jin per mu—each jin is small. Wheat: 1.7 yuan × 100 jin = 170 yuan. |
Increased efficiency by 170 yuan per mu, An additional 1,700 yuan in efficiency per ten mu. An increase of 17,000 yuan per 100 mu. An increase in efficiency of 170,000 yuan per thousand mu. |

2. Invention patent products of the anti-sticking and anti-blocking rotary seeding and fertilizing machine series ((1)-(3))
The origin and features of the anti-sticking and anti-blocking rotary seeding and fertilizing machine,
1. First, in recent times, the government has been focusing on grain production. In regions such as Anhui and Jiangsu, farmers have shifted from cultivating one crop per year to two crops per year—first wheat, then rice. Moreover, most farmers primarily rely on working away from home, leaving them with only limited time for farming during holidays. If there’s excessive rainfall, they can’t wait until the soil moisture reaches an optimal level before planting; instead, they’re forced to sow seeds into sticky, muddy soil.
2. Second, the government now requires conservation tillage and direct seeding—specifically, direct seeding on fields where all straw is returned to the soil. As a result, the original rotary seeding and fertilization method encounters issues such as sticky soil conditions, leading to blockages in fields with high stubble and thick stalks, which in turn cause gaps in rows, broken furrows, and low seeding efficiency. To address these challenges, we have developed a series of anti-blocking rotary seeding and fertilization machines.
(1) Dual-axis anti-sticking and anti-blocking rotary seeding and fertilizing machine
3. Next-generation patented product: Matching horsepower 120–160
4. Possesses all the features of a variable-speed Dual-Axis Rotary Cultivator and a variable-speed Rotary Tiller:
5. Anti-sticking patented product: The fertilizer tube is positioned inside the knife roller, with a spacious double-row arrangement both in front and behind the seed tube, and an anti-sticking plate design. This reduces machine adhesion and improves passability.
Working principle of the anti-sticking and anti-blocking rotary seeding fertilizer applicator: During operation, the rotary tiller blade 2 rotates, and the fertilizer tube 3 is positioned in front of the rotary tiller blade shaft 1. Wet, sticky soil clumps are crushed and thrown upward by the rotary tiller blade 2, then ejected backward. The anti-sticking plate 5 protects the seed tube 4 from adhesion at its front end. The fertilizer tube 3 is located in front of the rotary tiller blade shaft 1 and within the working trajectory (rotational range) of the rotary tiller blade 2. An anti-sticking plate is installed between the outer diameter of the rotary tiller blade 2 and the cover to prevent sticking. Meanwhile, since the fertilizer tube 3 is positioned in front of the rotary tiller blade shaft 1, during the movement of the rotary tiller blade 2, the blade continuously scrapes downward and forward, removing any soil clumps adhering to the fertilizer tube 3, thus ensuring smooth passage. Consequently, this anti-sticking and anti-blocking rotary seeding fertilizer applicator fundamentally solves the adhesion problems between the fertilizer tube 3 and the cover, as well as between adjacent fertilizer tubes 3. The seed tubes are arranged in two parallel rows with ample spacing between them; additionally, the wide-width wheat seeder (seed-dispensing device) has been optimized and modified to further reduce adhesion between seed tubes, thereby effectively addressing the issue of sticking between seed tubes.
1. The bottom of the fertilizer pipe is designed with MN13 high-strength, wear-resistant material to form an excavating plow tip, ensuring smooth operation on sticky soils without clogging, sharper cutting edges on hard soils, and a wear resistance lifespan 3 to 5 times longer than that of conventional plow tips.
2. Stainless steel fertilizer hopper with increased capacity, capable of holding 800–1,000 jin. Available in two- and three-hopper configurations.
3. The elastic scraper board effectively removes soil from the compaction roller, while the spring tines break up surface-scale crust and loosen compacted soil.
Compared with similar products, dry and hard soils can be tilled deeper or broken into finer soil clods. On wet and sticky soils, the machine exhibits excellent mobility. It can increase yield per mu by 10–15%, reduce fertilizer use by more than 30%, and help farmers save costs and increase income by 170–248 yuan per mu (compared to variable-speed rotary seeders). Additionally, operators can enjoy an additional net profit of 80–140 yuan per hour.

2. Possesses all the features of a variable-speed rotary spreader:
3. Anti-sticking patented product: The fertilizer tube is located inside the knife roller, and both the seed and fertilizer tubes are arranged in two parallel rows with ample spacing. Equipped with an anti-sticking plate design, this equipment experiences less adhesion and boasts improved passability.
4. Fertilizer application rate adjustment: Available in two types—standard and variable-speed.
5. Sowing methods: There are two types—broadcast sowing and furrow sowing.
Compared with similar products, this machine ensures smooth seeding on dry and hard soils and exhibits excellent passability on wet and sticky soils. It boosts yield by 10–15% per mu, reduces fertilizer use by more than 30%, and enables farmers to save costs and increase income by 170–248 yuan per mu (compared with variable-speed rotary seeders). For operators, it generates an additional net profit of 80–140 yuan per hour.
(3) Four-speed integrated shaft anti-sticking and anti-blocking rotary seeding and fertilizing machine
1. Next-generation patented product for 2024; matching horsepower: 120–180
2. Possesses all the features of a single-axis anti-blocking rotary tillage fertilizing seeder:
3. The difference lies in
(1) The single unit features two variable speeds and, when paired with the main unit’s two speeds, can achieve four different rotational speeds.
(2) The biggest highlight: The through-shaft design eliminates the issues of adhesion, congestion, and leakage in the intermediate transmission housing.
(3) High input shaft height: Compatible with a wide range of applications, at 560 (between G:535 and H:610).
(4) Compaction method: The same as for the flat seeding and dual-axis anti-sticking rotary tillage fertilizing seeder.
Compared with similar products, this machine ensures smooth seeding on dry and hard soils and exhibits excellent passability on wet and sticky soils. It boosts yield by 10–15% per mu, reduces fertilizer use by more than 30%, and enables farmers to save costs and increase income by 170–248 yuan per mu (compared with variable-speed rotary seeders). For operators, it generates an additional net profit of 80–140 yuan per hour.

| (Average annual) Shaanxi Market | (Average annual) | Five-year savings of 3,500 yuan | |
| Save 306 seeds | In Anhui, the seeding rate is 50–80 jin per mu. Taking 60 jin as the average and multiplying by 30% gives 18 jin. At 2 yuan per jin, this amounts to 2 yuan × 18 jin = 36 yuan (savings per mu). The daily seeding rates are 60, 80, 100, and 150 jin—let’s take (80 mu) as our benchmark. Calculation: 0.36 yuan × 80 mu = 28.8 yuan; daily seed cost savings: 28.8 yuan × 50 days = 144,000 yuan; five-year cost savings. |
One day (8 hours) saves 28 B0 yuan in labor costs; one year (10 days) saves 28,800 yuan in seed costs; five years (50 days) save 144,000 yuan in seed costs. | |
| Increase production by 106-15% | Yield per mu ranges from 800 to 1,100 jin; taking 800 jin as the base, with a 10% increase in yield, the additional output is calculated as follows: 800 × 106 = 80,000 jin. The increased yield per mu is 880 jin - 800 jin = 80 jin. At 1 yuan per jin, the additional income per mu is 80 jin × 1 yuan = 80 yuan. With 80 mu (average daily) and 50 days (10 days per year for 5 years), the total cultivated area over five years is 4,000 mu. Given the product’s lifespan of five years, the total additional income over five years is 80 yuan (additional income per mu) × 4,000 mu = 320,000 yuan. | Daily (8 hours) production increase fee: 6,400 yuan; annual (10 days) production increase fee: 64,000 yuan; five-year (50 days) production increase fee: 320,000 yuan. | |
| Save fertilizer | Anhui: The recommended fertilizer application rate is 80–140 jin per mu; taking 80 jin as the standard, trench application can increase fertilizer efficiency by more than 4096%. Calculating based on a 30% increase, 80 jin × 30% = 24 jin (fertilizer savings per mu). At 1.2 yuan per jin, this translates to 28.8 yuan saved per mu. Thus, 28.8 yuan × 80 mu = 2304 yuan (daily fertilizer savings). Over 50 days, this amounts to 2304 yuan × 50 = 115,200 yuan (total cost savings over five years). | One day (8 hours) saves 2,304 yuan in fertilizer costs; one year (10 days) saves 23,040 yuan in fertilizer costs; five years (50 days) save 115,200 yuan in fertilizer costs. | |
| Five-year increase in seeding efficiency | 1,200 (per capita income increase) × 50 days (life expectancy of five years) = 60,000 yuan (five-year increase in net profit) | Annual (10-day) net profit: 12,000 yuan; Five-year (50-day) net profit: 60,000 yuan. | |
| Total cost reduction and efficiency improvement | Note: Among them are the clothing industry cooperative, farming households, cost-saving and efficiency-enhancing initiatives, agricultural machinery cooperative, machinery purchasers, and cost-saving and efficiency-enhancing measures. | 650,535 yuan 624,700 yuan 71,335 yuan |

| Note: Benefit Description | 1. The four-speed common-axis benefit is based on the sowing, fertilization, and fertilization standards for certain regions of Anhui Province in 2020. | ||
| 2. The increase in production is based on the figures measured over many years by YAAO, which has expanded from Shaanxi Province to multiple regions across China since the 1980s, as well as by Shaanxi Yilin University of Science and Technology. | |||
| 3. The increased efficiency achieved by machine operators through seeding is based on the higher yields obtained nationwide, while maintaining seeding quality that is equivalent to or even surpasses that of locally comparable machinery. | |||
| 4. The above three items are all estimated based on the minimum standards. | |||
Note: With the exception of the model specifically designed for Anhui, all other seeders can be used.
3. No-till wheat seeding and fertilizing machine
No-till fertilization and seeding for wheat, mustard, and oats in dryland areas of northern regions. In areas with two harvests per year or one harvest per year, the entire process—including furrow opening, straw crushing, fertilization, seeding, soil covering, and compaction—can be completed in a single operation on either the root-recommended surface or the surface where all straw has been fully crushed.
It features all the characteristics of the YAAO variable-speed rotary seeder, employs an invention patent technology to prevent clogging, and performs meticulous soil preparation in the seeded area while leaving the fallow strips uncultivated. The straw is finely chopped and evenly spread across these fallow strips. As a result, the seeded bed has fewer weeds, ensures that the full amount of straw is distributed without causing blockages, and allows for precise, fine-tuned soil preparation that boosts yields. After seeding, a seedbed with 15 cm-wide, 15 cm-deep furrow strips is formed, along with 20 cm-wide fallow strips and 12 cm-wide single-row compaction zones within the seeded strips. This achieves wide-band trench seeding with minimal tillage (see diagram).
Difference from a variable-speed rotary tiller:
1. Increase the line spacing by 5-6 centimeters.
2. Single-line suppression.
3. The centers of the cultivation belt, the seed-fertilizer management system, and the single-row compaction roller are aligned in a straight line, front to back, at the same position.
Compared with similar products, this machine ensures smooth seeding on dry and hard soils and exhibits excellent passability on wet and sticky soils. It boosts yield by 10–15% per mu, reduces fertilizer use by more than 30%, and enables farmers to save costs and increase income by 170–248 yuan per mu (compared with variable-speed rotary seeders). For operators, it generates an additional net profit of 80–140 yuan per hour.

At a charge of 35 yuan per mu, this means an additional 350 yuan per hour. Multiplied by 8 hours per day, that’s an extra 2,800 yuan per day. This boosts efficiency by 60%; 2,800 yuan/day × 7 days of sowing per year = 19,600 yuan/year in additional earnings. Over 5 years, this amounts to 98,000 yuan in additional earnings: 98,000 yuan × 5 years = 490,000 yuan in total additional earnings over 5 years. | Note: 5,000 m × 2, cultivation width of 2 mu ÷ 666 = 16 mu of cultivated land per hour × a fee of 35 yuan per mu = 560 yuan per hour. | Compared with its peers, YAAO has a daily net profit of 2,800 yuan, an annual net profit of 19,600 yuan, and a five-year net profit of 98,000 yuan. |
4. Oilseed and Wheat Dual-Purpose Fertilizer with Seeder Drill
(1) This machine is a new-generation equipment jointly developed by Xi'an YAAO Agricultural Machinery, Northwest A&F University, Shandong Academy of Agricultural Machinery Sciences, building upon the nearly fifty-year-old, mature technology of the YAAO brand wide-width, high-yield rotary seeding and fertilizing machine.
(2) Possesses all the features of a single-axis anti-blocking rotary tillage fertilizing seeder:
(3) The difference lies in
1. Equipped with a multi-functional seed-metering device, it can sow wheat, highland barley, as well as oilseed rape; and also small-grain economic crops such as buckwheat and sorghum.
2. The seeding rate is adjusted using a stepless transmission technology, enabling precise, convenient, and accurate adjustment of seeding rates for wheat and rapeseed. Powered by ground wheels, this system is stable and reliable, capable of meeting the seeding rate requirements—from 3 liang to 80 jin—for various regions and different planting patterns.
3. Reduce seed usage by 40% (from 400–500 grams per mu for rapeseed to 200 grams), while increasing yield by 15–20% (from around 400 jin to 460–480 jin per mu).
4. By replacing the compaction roller, installing the intermediate furrow-opening device, and replacing the drive motor, this equipment can be adapted for cultivating semi-water paddy fields and muddy fields in southern regions.
Trial Report on the Rapeseed Sowing Base in Qinghai Province
Compared with similar products, this machine ensures smooth seeding on dry, hard soils and exhibits excellent passability on wet, sticky soils. It boosts yield by 10–15% per mu, reduces fertilizer use by more than 30%, and enables farmers to cut costs and increase income by 170–248 yuan per mu (compared with variable-speed rotary seeders). For operators, it generates an additional net profit of 80–140 yuan per hour.
