A tractor transmission system is a mechanism that transmits engine power to the wheels of the tractors. It consists of many gears and shafts that work simultaneously to provide a variation in the speed and torque of the tractor engine’s power.
The tractor transmission system consists of several parts, including a clutch, gearbox, gear speeds, and brakes. A clutch is used to engage and disengage the transmission and the engine. After that, the set of gears present in the transmission system is used to control the engine power, torque, and speed.
In India, only manual transmission is provided in the gear system of the tractors. The automatic transmission system in tractors is not available in India, but other countries in the world have tractors with the automatic transmission system.
The transmission system is connected to the final drive, which transmits engine power to the wheels using the set of gears provided, thereby helping the tractor to move forward or reverse.
Overall, the tractor transmission system is an important part of a tractor that helps to control the power, torque, and speeds of the tractor. Let’s discuss the transmission system in detail, such as different types of transmission systems, tractor gears, and more.
A tractor’s transmission system is an essential part that ensures optimum engine power reaches the wheels of the tractor. The different types of gearboxes used in the tractors are sliding mesh, constant mesh, partial constant mesh and synchromesh. Let’s discuss each of them one by one with their advantages and disadvantages.
A sliding mesh gearbox is a manual type of transmission primarily used in tractors. It is the oldest and simplest type of gearbox.
In this type of gearbox, the gears are arranged on the main shaft and counter shaft. At a particular time, only one set of gears in the main shaft and counter shaft mesh with each other.
If two pairs get meshed at the same time, they will try to rotate the main shaft at different speeds, thereby resulting in the breaking of one of the shafts.
A constant mesh gearbox is also a manual transmission used in tractors and many other heavy-duty vehicles. In this gearbox also, the main shaft is splined. The gears on the main shaft are in constant mesh with the gears on the counter shaft.
However, some gears on the counter shaft are sliding back and forth to engage and disengage with the gears on the main shaft.
This process is done by disengaging the gearbox and the engine with the help of a clutch and then engaging the different pairs of gears on the main shaft and counter shaft with the help of a fudge.
The gear shifting process is smoother compared to the one in sliding mesh, making it better than the sliding mesh gearbox.
This type of transmission system is a combination of both sliding mesh and constant mesh gearboxes. In this gearbox, some set of gears in both the main shaft and counter shaft are always engaged (constant mesh), while some set of gears is engaged or disengaged as per requirement (sliding mesh). This type of transmission system is provided in many tractor models.
It is the most advanced type of gearbox provided in tractors in India. It is also a manual transmission system designed for smoother shifting of gears than the constant mesh gearbox.
In this type of gearbox, each gear consists of a synchroniser ring that helps to match the input shaft speed with the output shaft.
Once the operator changes the gear, the synchroniser ring helps to speed up or slow down the gear speed so that the gears can mesh easily without causing any damage to the transmission system.
In this gearbox, helical-cut type gear teeth are provided, which have angled teeth. These types of gear teeth are smoother than the straight-cut gear teeth and help in the smoother meshing of gears.
The overall gear shifting process causes fewer vibrations and helps in smoother transmission. The lifespan of a synchromesh gearbox is higher than the other types of gearboxes.
It is the combination of both synchromesh and constant mesh gearbox. In this type of gearbox, the lower gears (one and two) do not have synchroniser rings, while the higher gears (three, four and five) consist of a synchroniser ring. The gear shifting in this type of transmission system requires more skill and expertise compared to a full synchromesh gearbox.
Here, you will learn about the transmission system in the top 5 tractor brands in India. Let’s discuss them in brief.
John Deere tractor company uses the latest technology while manufacturing its tractors. The transmission systems provided in the John Deere tractors are collarshift transmission and synchromesh transmission. The brand also provided TSS (Top Shaft Transmission) in both types of gearboxes.
Mahindra Tractors is the topmost tractor brand in India. It manufactures tractors as per the needs of farmers and the working environment. The brand offers all types of transmission systems in its tractors, including sliding mesh, constant mesh, partial constant mesh, synchromesh, and partial synchromesh transmission.
Massey Ferguson Tractors is the sub-brand of TAFE Group (Tractor and Farm Equipment Company). It is among the top ten tractor brands in India that produce powerful tractors with efficient transmission systems. The brand offers different types of transmission systems, including sliding mesh, partial constant mesh, constant mesh, and partial synchromesh gearboxes.
Swaraj Tractors is one of the most popular names in the Indian tractor industry. It manufactures tractors according to the farming conditions in India. The Swaraj tractor gear pattern is operated with many transmission systems, including sliding mesh, partial constant, constant mesh, and synchromesh gearbox.
Sonalika Tractors is another famous name in the Indian tractor industry and is among India’s top 5 tractor brands. The Sonalika tractors consist of different transmission systems, including sliding mesh, constant mesh, and synchromesh gear. The company does not offer partial constant mesh or partial synchromesh gearbox in its tractors.
