The Deere 6003 series high-power tractor was designed and manufactured by John Deere Company of the United States. It was introduced by John Deere Tiantuo Co., Ltd. in 2001. After two years of adaptability and reliability tests, it was promoted to bulk assembly in 2003. market. main feature
First, large displacement engine: using John Deere POWERTECH turbocharged engine, torque reserve
With a coefficient of more than 25%, the Model 6403 uses a 4045T Deere engine, four-cylinder, 2100 rpm, rated power of 106 hp and a displacement of 4.5 liters. Type 6603 uses 6068T Deere engine, six-cylinder, in-line, water-cooled, 2100 rpm, rated power 120 hp, displacement 6.8 liters.
Second, the assembly of imported gearboxes. The main gear lever adopts synchronous gear shifting, and the auxiliary gear lever adopts mesh shifting
The gears make shifts smooth and easy. The forward gear shift is 3 sections and 9 gears, and the back is 1 section and 3 gears. The traveling speed is JD6403 type is 3.0 to 29.5 kilometers/hour; the JD6603 type is 3.1 to 31.2 kilometers/hour. The design of the hydraulic oil filter cartridge is unique, and one maintenance is equivalent to replacing three filter cartridges at the same time.
Third, the unique front axle
The unique Caster/Action mechanical front axle provides greater traction. Steering cylinder and front axle
Cast into a monolithic, 12-inch caster caster makes the wheels slightly tilted when turning, turning into the underside of the frame, achieving a steering angle of up to 52 , with a turn radius of only 4.12 meters.
Fourth, hydraulic system and power output shaft
(1) The hydraulic system has various adjustment methods such as force, position and integration, and the suspension device conforms to the national type II standard.
It is matched with various farm implements produced in China, and there are many varieties of farm implements. The relatively independent hydraulic output valve assembly is very convenient to use and maintain.
(2) The two-speed power output shaft is fixed in the dry shaft sleeve and provides two rotation speeds of 540 and 1000 rpm.
It is convenient and quick to change, so long as the power output shaft is pulled out during the conversion, it can be inserted in the direction of change, and there will be no problem of oil leakage.
(3) The hydraulic pump is a double gear pump, and the flow of the pump at 2100 rpm is JD6403 type 53.3 liters/minute, JD6603
The model is 66.8 liters/set.
Fifth, the arc-shaped cab
(1) The cab maintains a circular design by Deere. High-strength skeleton used to meet -35°C
The safety requirements of anti-turnover impact in the state of In addition to the skeleton, the cab is made of toughened glass components, providing the driver with an excellent view, good sealing, and low noise.
(2) The interior of the cab is spacious and comfortable. All the foot pedals are installed above the floor with super noise-absorbing ability. The arrangement of the joysticks takes full account of the ergonomic requirements and is easy to handle. The rear window can be opened with one hand, and the working status of the suspension mechanism and the tow bar can be clearly observed.
