Large and medium-sized tractor-mounted agricultural implements are designed for high-efficiency, large-scale operations, matching tractors with 50-300+ horsepower.
They focus on integration, precision, and multi-functionality-here are the core types and characteristics:
1. Soil preparation implements (core for large-area land sorting)
Combined soil preparation machines: Integrate plowing, harrowing, and leveling functions. Complete multiple operations in one pass to save time and reduce soil compaction. Suitable for large farms and contiguous plots.
Heavy-duty reversible plows: With 3-6 plowshares, they plow deeply (25-40cm) and turn soil evenly. The reversible design ensures flat plowed land and adapts to large-scale continuous operation.
Subsoiling and loosening machines: Equipped with high-strength shovels, they loosen deep soil (30-50cm) without turning the plow layer. Improve soil permeability and water storage capacity, matching medium and large tractors for dryland or compacted soil.
2. Sowing & fertilizing implements (precision and efficiency oriented)
Integrated precision seeding-fertilizing machines: Support variable-rate sowing and fertilization. Match with Beidou navigation to control seed spacing (2-15cm) and fertilization amount accurately. Save seeds and fertilizers by 10-15% compared to traditional equipment.
Large-area broadcast seeders: For crops like wheat or forage grass. Spread seeds evenly with a working width of 6-12m. High operating efficiency (80-150 mu per hour) to meet large-scale sowing needs.
Film-covered seeding machines: Integrate ridge forming, film covering, seeding, and drip irrigation pipe laying. Suitable for cash crops such as cotton, corn, and vegetables in arid areas. Improve seedling emergence rate and water retention.
3. Field management implements (for mid-late stage of large-scale crops)
High-clearance sprayers: With a ground clearance of 1.2-2.5m, they avoid damaging crop seedlings. Equipped with GPS positioning and automatic spraying systems. The working width is 8-20m, and the liquid tank capacity is 500-2000L for large-area pest control.
Mechanical weeding machines: Use rotary blades or hoe-type tools. Match with tractor power to remove weeds between rows. Reduce chemical herbicide use and adapt to green agricultural development.
Topdressing machines: Implement strip fertilization or deep fertilization. Directly deliver fertilizers to the root zone of crops. Improve nutrient utilization rate and avoid fertilizer waste in large fields.
4. Harvesting auxiliary implements (matching large-scale harvesting operations)
Forage harvesters: Cut, chop, and convey forage crops such as corn stover and alfalfa. The output is 5-15 tons per hour. Provide high-quality feed for large-scale animal husbandry.
Straw crushing and returning machines: Crush crop straw (wheat, corn) into 3-5cm segments and mix them into the soil. Working width is 3-6m. Improve soil organic matter content and reduce environmental pollution.
Root crop diggers: For potatoes, sweet potatoes, and other crops. Dig, separate soil, and collect tubers in one operation. Reduce manual labor and improve harvesting efficiency (30-80 mu per hour).
