1. Preparation before starting the machine
Before using the machine, it is important to perform a thorough check to eliminate potential problems and effectively prevent accidents. Generally, the diesel engine and chassis should be checked for oil, gas, or water leaks. Check whether the diesel engine has sufficient cooling water. Check the level and quality of the lubricating oil in the engine crankcase. Check the oil level in the gearbox gears. Unscrew the oil check screw on the crankcase, and gear oil should flow out from the screw hole. If there is a lack of oil, add more. Check the tension of the triangular belts. If the belts are too loose, they should be adjusted. Check the tire pressure. If the pressure is too low, they should be adjusted.
2. Starting the diesel engine
Pull the tractor's clutch and brake lever to the "engage" position. Place the gearshift lever in neutral. Return the throttle lever to its starting position. Open the decompression lever with your left hand and grasp the starter handle with your right hand, then crank the diesel engine crankshaft. Gradually increase speed, quickly release the decompression lever with your left hand, and continue cranking the starter handle at a faster speed with your right hand until the diesel engine ignites.
After the diesel engine ignites, check whether the oil pressure gauge rises. Listen for the sound of the diesel engine running. Observe the exhaust smoke. Once everything is confirmed to be normal, let the diesel engine run for a while to allow the water temperature to rise to between 40 and 60 degrees Celsius.
3. Exit the Tractor
After the engine has warmed up, you can begin moving forward. When you begin moving forward, raise the front support of the tractor. Do not grasp the steering handle, and pull the lever control bar sideways until it cannot be pulled any further. Pull the clutch and brake lever to the "clutch" position. Move the shift lever to the desired gear. Move the clutch and brake lever from the "clutch" position to the "engage" position so that the tractor begins to move slowly. Control the throttle according to the size of the tractive load.
4. Shifting Gears
During tractor operation, when the load and road conditions change and it is necessary to adjust the tractive force or driving speed, you can shift gears. Before shifting gears, quickly pull the clutch and brake lever to the "clutch" position. Place the shift lever in the desired position. Push to the left for low gear and pull to the right for high gear. Slowly engage the clutch and the tractor will reach the appropriate speed.
5. Steering
The billet tractor is steered by controlling the left and right steering handles. When turning, first reduce the accelerator pedal and slow down the driving speed. Then, squeeze the right steering handle to turn right. Squeeze the left steering handle to turn left. To make small directional adjustments while traveling straight ahead, it is not necessary to squeeze the steering handle; simply push the control bar. When using the seat device, push the right pedal forward to turn the tractor right, and push the left pedal forward to turn left.
6. Brake and Stop
The brake lever of the billet tractor is integrated with the clutch lever. The clutch crankshaft and brake lever are also integrated into a single component. When the lever moves from the engaged position to the disengaged position, the brake lever's oscillation angle is small and has no braking effect. As the lever is pulled further back, the brake lever's oscillation angle increases, and the brake begins to operate, stopping the tractor. If you are towing a trailer, you must also depress the trailer brake at the same time. After the tractor stops, release the brake. To prevent the clutch spring from aging, place the clutch lever in the engaged position, let the diesel engine run at low speed without load for a few minutes to allow the water and oil temperatures to gradually drop, then turn off the throttle and shut off the engine.
Please note that you should not suddenly increase the throttle before turning off the engine. After turning off the engine, close the fuel tank switch. Turn the flywheel so that the piston is at top dead center. This can better protect the machine.
Product Introduction: The billet tractor is a dual-purpose tractor, both pulling and driving. It has a compact structure, is durable and reliable, easy to handle, has good passing capacity, and is equipped with a seating device. The billet tractor has greater power and higher efficiency. It is suitable for work in rice fields and drylands, as well as in orchards, vegetable gardens, and hilly areas. With the corresponding agricultural implements and accessories, it can perform plowing, rototiller cultivation, soil preparation, furrowing, sowing, transporting, and other work. It can also be used as a stationary work engine for irrigation and watering, water spraying, threshing, flour milling, fodder processing, etc. This machine has the advantages of a simple and compact structure, easy operation, low weight, reliability, easy repair, and good ground clearance. This machine is widely suitable for work in rice fields and drylands in flat, mountainous, and hilly areas. With the appropriate agricultural implements, it can perform a variety of tasks, such as plowing, rototiller cultivation, harvesting, sowing, threshing, and dewatering. It can tow a trailer for short-term transport and is equipped with lighting devices, allowing it to be driven at night.
The billet tractor is a small tractor. In Europe and the United States, it is known as an orchard tractor. It is a multipurpose travel machine primarily used for traction and transportation, and is powered by systems such as the engine, chassis, and electrical systems. The billet tractor moves thanks to the power of the internal combustion engine, which is transmitted through the transmission system. The drive wheels acquire traction torque and, through the tread patterns and tire surfaces, exert a small horizontal and rearward force (tangential force) on the ground. This reaction force is the tractive force (also known as forward force) that propels the tractor forward. It has a simple structure and low power, making it suitable for cultivating small plots of land. The driver holds the handlebar to control the tilling mechanism and tows or drives agricultural implements to perform work.
Features:
This product features high power, small volume, low weight, easy starting, low fuel consumption, good reliability, easy operation and repair, and wide application. It is widely used as a supporting engine for machinery such as billet tractors, agricultural tricycles, water pumps, generator sets, small boats, crushers, small engineering machinery, etc. It is also used in conjunction with rototillers and microcultivators.
Plowing Work
When the billet tractor pulls a simple two-way plow, one of the drive wheels is on the uncultivated soil and the other drive wheel is in the plow furrow. The coefficient of adhesion between the two wheels and the soil is different, and the slip rate is also different, causing the equipment to tend to deviate in one direction. For the Dongfeng-12 billet tractor, the following adjustments can be made to resolve this problem: Adjust the gap value (swing gap) between the two left and right adjusting screws.
