Product Advantages

1. 50HP Moderate Power for Efficient and Economical Operations on Small and Medium-Sized Plots:

The HH504 tractor is equipped with a 50-horsepower engine, delivering power precisely matched to the operational needs of family farms, orchards, and small, hilly plots of 20-80 mu (approximately 16-18 acres). When tilling a 10-mu (approximately 16-18 acres) plot of corn or soybeans, it can drive a 1.8-meter-wide rotary tiller at a speed of 5-6 km/h, completing 4-5 mu (approximately 16-18 acres) of tillage in one hour, achieving a tillage depth of 20-22 cm. This eliminates the inefficient tillage depth associated with 30-horsepower models, which suffer from insufficient power, nor the high fuel consumption associated with 70-horsepower models, which suffer from overpower when operating on small plots. Based on an average annual operating time of 800 hours, this tractor can save approximately 1,200 yuan in fuel costs compared to a 60-horsepower model, achieving both efficiency and economical operation for small and medium-sized plots.


2. 4WD: Stable Operation in Various Terrains:

Thanks to its four-wheel drive (4WD) system, deep-tread paddy field tires, and reinforced front axle, the HH504 offers exceptional maneuverability in complex terrain, including muddy paddy fields, rain-soaked slopes, and gravel fields. For example, before transplanting rice seedlings in the rainy spring paddy fields of southern China, the 4WD system evenly distributes power to all four wheels, preventing single-wheel slippage and muddying, ensuring the tractor's smooth travel along the planned route and maintaining a ±3cm deviation in the transplanting position. When transporting fertilizer on a gentle 12° slope in a northern hilly orchard, the tractor maintains stability even on fallen leaves or small gravel, preventing fertilizer spillage. Compared to two-wheel drive models, the interruption rate of operations in complex terrain is reduced by 70%, effectively preventing delays to the farming season due to terrain problems.


3. Flexible Design for Unobstructed Operation in Narrow Spaces:

The HH504's dimensions are optimized for confined environments, such as small and medium-sized plots of land and orchards. Its minimum turning radius is only 3.2 meters, and its width is limited to 1.6 meters. When weeding in apple orchards with a row spacing of 2.5 meters, it can easily maneuver between rows of trees without scratching trunks or branches. When operating in small vegetable gardens (3-4 meters wide) near rural residential plots, it can turn and U-turn flexibly, eliminating the need for repeated adjustments and significantly reducing operation time. Furthermore, its moderate height allows for easy storage in simple 2.2-meter-high agricultural machinery sheds, addressing the limited storage space for small and medium-sized farmers.


4. 50HP Power: Strong Adaptability, Efficiently Connecting to Various Agricultural Implements:

The 50-horsepower stable power output is compatible with a wide range of agricultural implements commonly used by small and medium-sized farmers without requiring additional modification. The rear three-point hitch can attach a 1.5-meter-wide seeder, a 1.2-meter-wide trencher, a 200-liter crop protection sprayer, and more. The PTO shaft speed can match a conventional 540 rpm, meeting the power requirements of most agricultural implements. In spring, a seeder can be used to sow vegetables with a seed spacing error of ≤2cm. In summer, a sprayer can spray a 5-mu orchard in under an hour. In autumn, a trencher can be used to dig 25cm-deep drainage ditches in a vegetable garden. This multi-purpose machine offers greater adaptability compared to specialized agricultural implements, reducing farmers' tool procurement costs and improving agricultural machinery utilization efficiency.
