Familiarity with tractor spare parts seems essential for those who work in this field. The tractor is one of the most widely used agricultural transport machines, which is very complex and advanced, and many parts are used in its construction, and the tractor spare parts are very diverse. Many farmers use the tractor to plow the agricultural land or moving agricultural products.
Since this machine is widely used in agriculture, there is a high possibility that its spare parts such as felt bowl, clutch plate or hydraulic pump will have problems. Most of the consumable parts of the tractor must be replaced after some time of use. Therefore, familiarizing farmers with tractor spare parts and its consumable parts is inevitable. Some other important spare parts of agricultural tractors are felt bowl, cylinder head, cylinder, water plug, oil plug, hydraulic pump and valves. These parts are among the most important spare parts of the tractor and they play an important role in the correct operation of the tractor, and because they are under more pressure and are used a lot, the possibility of their breakdown and damage is very high.
Tractor engine piston
Head or crown, ring grooves, body or skirt, surfaces or supports and finger hole are the main parts of the piston.
Crown or head
The crown or head is the upper part of the piston, which is shaped like a circle. Usually, this part of the piston is made in different shapes. You can see the types of crown or piston head in the figure below.
Ring grooves
Ring grooves are another part of the piston. In the tractor engine, the grooves are where the rims are placed. Usually, each piston has 3 to 5 ring grooves. The oil ring is the lowest groove. The ends of the grooves have holes that are used to enter the oil into the piston.
Support or column
This part is another part of the parts that make up the piston. The position of these edges is between the grooves and their function or supports is to keep and help support the rims inside the grooves.
Piston body or skirt
Piston body or skirt It is another part of the piston whose position is under the grooves.
Finger hole
Finger hole is another part of the tractor piston. The connecting rod is connected to the piston through this hole. The surfaces around the finger hole are very thick, which makes this part stronger and more resistant.
Piston ring in the tractor engine
The piston ring in the tractor engine has the task of reducing and maintaining the contact between the cylinder wall and the piston and maintaining its necessary compression. to do This will prevent premature wear and friction.
The material of the piston ring is gray cast iron. The reason for choosing gray cast iron to make the piston ring is that the gray cast iron alloy has high resistance and does not show much sensitivity to heat. Gray cast iron has a very good elasticity.
Tractor piston rings
In general, gasoline engines have three or four rings and diesel engines have five, six or seven. They have a ring number.
Division of rings according to the task
Rings are divided into two groups in this respect:
- Dense or waist ring: compression or compressor rings prevent the escape of gas or its leakage.
- Oil ring: When the piston moves down and is in breathing mode, the role of the oil ring is to clean that part.
Tractor seat
Tractors are one-passenger vehicles and only one seat for the driver is installed in these devices. Therefore, this part of the tractor can be considered one of the important parts of the tractor. The tractor seat can be damaged for various reasons, including impact or environmental conditions. The reason this tractor seat plays a significant role in the tractor's performance is that the driver sits on the seat and controls the machine, so the tractor must have a comfortable seat that can sit comfortably and drive the tractor.
Tractor steering hydraulic pump
Another tractor spare part is the hydraulic steering pump. This part plays a significant role in the performance of the tractor. The role of this part is to inject hydraulic oil into the hydraulic system of the tractor to move the steering wheel easily. If this part has a problem, the driver will not be able to move the wheels of the tractor. This is the reason for the importance of this piece.
