From the "iron teeth" to the intelligent center: the evolutionary history of the drive rotary tiller
In 1955, the first domestic walking tractor supporting rotary tiller was born in Henan, and 34 machetes made "cattle farming" history for the first time. Today, the horizontal rotary tiller has occupied 90% of the market share, the knife shaft speed has been increased from the early 180 to 250 RPM, and the output power of the tractor has been achieved to achieve the trinity of "ploughing, raking and breaking soil". On the production line of Shandong Aolong, the no-tillage fertilization and seeding rotary tiller is coming off the line - one operation is completed to turn the soil, sow and cover the soil, the efficiency is 4 times higher than the traditional way, and the cost saving per mu is 120 yuan.
The core mystery of the rotary tiller is hidden in the arrangement of the blade. The IT225 scimitar is distributed in a spiral, cutting in the opposite direction of the tractor, and the soil reaction forces create thrust, allowing the 30 HP tractor to move easily in the heavy soil. Tests conducted by an agricultural machinery factory in Jiangsu show that after optimizing the blade Angle, the energy consumption of the rotary tiller is reduced by 15%, the ploughing depth is increased from 12 cm to 18 cm, and the soil moisture retention capacity is increased by 20% while breaking the bottom of the plow.
Second, the "all-round player" on the field: When the scene innovation is carried out
In the terraces of Liupanshui, Guizhou province, the folding rotary cultivator shows its "deformation" trick - the width of the knife shaft can shrink from 1.2 meters to 0.8 meters, and it can turn flexibly between the 1.5 meters wide field ridge. This customized model for 1.2 billion mu of hills and mountains has increased the agricultural mechanization rate in Southwest China by 14% in five years. In the northeast black land, the rotary tiller equipped with the subsoiling shovel is creating new value: rotary tillage + subsoiling synchronous operation, breaking the 30cm plow bottom, increasing the depth of corn roots by 40%, and improving drought resistance by 35%.
The addition of intelligent sensors allows the rotary tiller to become a "land doctor". On the monitoring screen of a smart farm in Sichuan, the soil temperature, humidity and PH value beat in real time, and the rotary tiller automatically adjusted the ploughing depth according to the data. "Last year, the lodging rate of corn dropped 60 percent, thanks to these 'smart iron teeth.'" Farmer Li Jianguo calculates an account: the intelligent rotary tiller increases fertilizer utilization by 25% and increases production by 300 jin per mu.
Third, from "can work" to "wise farming" : the future has come to the three major trends
Energy-saving revolution: Weichai Rewo's hybrid rotary tiller is being piloting in Northeast China, with dual power of diesel engine and motor, fuel consumption is reduced by 18%, and it can work for 8 kilometers after charging for 1 hour. A more radical exploration comes from BYD, whose electric rotary tiller is equipped with blade kinetic energy recovery technology, energy utilization rate is increased by 30%, and it is expected to be mass-produced in 2026.
Joint operation matrix: In Shihezi, Xinjiang Province, a tomato harvest rototiller demonstrates the "all-purpose mode" - picking tomatoes at the front end, rotating tilling the soil at the back end, and simultaneously removing mulching film. This "harvest + land preparation" integrated machine has increased the mechanization rate of characteristic crops by 40% and reduced the cost per mu by 300 yuan. According to the data, in 2024, the sales of combined rotary tillers increased by 37%, becoming the new darling of the market.
Intelligent transition: The AI rotary farming butler developed by Jiangsu University realizes "remote diagnosis" through 5G networking. In Suzhou, Anhui province, operator Wang Qiang's mobile phone received an early warning: the temperature of the knife shaft bearing was abnormal. Three hours later, maintenance personnel arrived with the parts, avoiding a possible shutdown accident. This failure warning 72 hours in advance, so that agricultural machinery attendance increased by 45%.
Fourth, the "Chinese wisdom" in the land: the hard truth behind the data
Spring farming data in 2024 show that the national rotary tiller operation area exceeded 1.2 billion mu, and the mechanical tillage rate reached 97%. In Panzhou, farmer Feng Mingde's 120 acres of flue-cured tobacco land, the rotary tiller tills 10 acres a day, equivalent to the workload of 10 cows. More importantly, deep rotary tillage increased soil organic matter content by 0.5% and increased income by 300 yuan per mu. Behind these figures, the localization rate of the core components of domestic rotary tiller has exceeded 92% - from blade materials to transmission gears, from hydraulic systems to smart chips, Chinese agricultural machinery is getting rid of "ocean core" dependence.
Standing on the ridge in 2025, in the roar of the rotary tiller, there is the rice bowl philosophy of the Chinese people: when 34 pieces of scimitar turn up new soil, it is not only seeds, but also the temperature of science and technology. From the unmanned driving in the paddy fields of Jiangnan to the precise deep drilling in the northwest Gobi, this "steel dancer" is writing a new farming civilization - it makes the land healthier, makes farmers more decent, and makes Chinese grain more confident.
