The 604 tractor is a wheeled tractor widely used in agricultural production. The following is a detailed introduction:
Performance Parameters
Engine: Typically uses a four-cylinder inline diesel engine with a rated speed of approximately 2200 rpm, a nominal power of 60 horsepower, and a measured net power of approximately 45-50 horsepower.
Peak torque can reach approximately 200 Nm, with a power reserve coefficient of 1.2, making it well suited to short-term overload conditions and heavy-duty operations.
Transmission: Most are equipped with an 8+8 shuttle shift, and some also feature a crawler gear. The gear range generally ranges from 0.3 to 30 km/h, with crawler gear speeds capable of as low as 0.5 km/h, meeting the specific speed requirements of operations such as precise seeding and furrowing.
Tire Configuration: Common front tire sizes are 6.5-16mm, and rear tires are 11.2-28mm.
Paddy field tires with a tread depth of 25mm or greater can improve sinkage resistance by 40%. Dryland tires typically have a contact patch of 0.32 square meters and improve traction by 15%.
Hydraulic System: A rear-mounted independent oil pump with a flow rate of approximately 25L/min and a lifting capacity of 1.2 tons or greater is available, making it suitable for implements such as 1.5-meter rotary tillers. A response time of 3 seconds or less enables rapid raising and lowering of suspended implements.
PTO Shaft: Features dual-speed outputs of 540/760 rpm, with a 1000 rpm option available on some models. This allows for compatibility with a variety of agricultural implements, such as straw returners and balers.
Power output stability is ±3%, minimizing equipment failures.
Technical Advantages
Power Optimization: Some 604 tractors utilize turbocharging technology, resulting in a power reduction of ≤10% at altitudes above 1,500 meters, compared to ≥25% for standard naturally aspirated models.
Fuel Economy: Fuel consumption is ≤7.5L/100km, approximately 12% lower than comparable models. Based on 200 hours of operation per year, this translates to an annual fuel cost savings of approximately 3,000 yuan.
Comfortable Control: Equipped with hydraulic power steering, a steering wheel angle of ±50° and a turning radius of ≤4.5 meters, this improves maneuverability by 30% in operating environments such as orchards and greenhouses. Some models also feature a cab with sound insulation and double-glazing, keeping in-cabin noise levels to ≤85dB, reducing the risk of hearing damage.
Reliable Structure: The chassis is reinforced, with a main drive shaft diameter of 45mm, 10% thicker than competing models, and a gear module of ≥3.5, resulting in 25% improved impact resistance. The transmission and rear axle are sealed to IP67 and can withstand short-term wading operations up to a depth of 50 cm.
Applicable Applications and Supporting Agricultural Implements
Applicable Applications: The 604 tractor is a small to medium-sized agricultural machine suitable for a variety of terrains, including hilly and plain terrain. It can be widely used in fields such as tillage, transport, and light agricultural operations.
Supporting Agricultural Implements: A variety of agricultural implements are available to meet different operational needs, including rotary tillers, conventional plows, hydraulic reversible plows, straw returners, trenchers, and bulldozers.
