In order to protect the soil, it is necessary to ensure that the grounding ratio pressure remains low.
In order to prevent the formation of plough bottom in dry land and maintain soil moisture to prevent drought, it is recommended to use crawler and towing operations. This method is also effective in protecting paddy fields from damage to the hard bottom layer and ensuring normal cultivation. It should be noted that the pressure of wheel trailing ground is much higher than that of crawler dragging, which can result in a low seedling emergence rate of only 30%-40%. However, if crawler dragging is used, the seedling emergence rate can still reach 80%-90%. In addition, the tugboat ruts left in paddy fields can pose a problem for rice planting and harvesting, and even cause the mud feet to deepen, making it impossible to cultivate. Therefore, it is important to take measures to prevent such damage and preserve the productivity of the land.
The benefits of conducting deep turning load operation are significant due to the large magnitude of the traction force involved. Deep turning can yield better results compared to other turning operations due to its ability to handle a higher level of load with ease.
When it comes to comparing the performance of crawler tractors and wheel tractors, the former comes out on top. The traction force of a crawler tractor that weighs the same as a wheel tractor is around 1.4 to 1.8 times greater, which significantly increases its overall traction efficiency. While wheel tractors have a traction efficiency rate of around 55-65%, crawler tractors can achieve between 70-80%. As a result, with the same horsepower, wheel tractors lose an extra 15% of effective power compared to their crawler counterparts.
3. High operation efficiency
When it comes to farmland operations, tractors are an essential piece of equipment. They are used for the rotary tillage, plowing, raking, and sowing of crops. The typical speed for rotary tillage is around 5-6km/h, while plowing can be done at a speed of 7-9km/h, and raking at 10-12km/h.
Whether the tractor is equipped with wheels or crawlers, the tillage speed is comparable. But, the advantages of a crawler tractor become more apparent in the traction it can provide. When dragging heavy loads across the farmland, the crawler tractor can keep up with the wheel tractor without losing any speed, and its traction advantage remains visible.
4. Strong passability and climbing ability
The crawler tractor exhibits impressive slope stability against overturning and sliding. This is due to its low center of gravity and large adhesion coefficient. In addition, it boasts excellent maneuverability with a small turning radius and is capable of cross-country travel thanks to its strong climbing ability. These features make it well-suited for use in farmland and terraced operations in mountainous and hilly areas. It outperforms wheel dragging equipment, particularly after the installation of rubber tracks, allowing it to operate as an all-terrain machine.
5. Operation comfort
Nowadays, crawler tractors have undergone significant improvements to enhance their performance and user experience. Most models have embraced hydraulic power steering, fully enclosed shock-absorbing cabs, and optional air conditioning and heating systems. They also feature digital instruments that provide crucial information to the operator. These advancements have significantly reduced noise levels, improving driving comfort, and overall user satisfaction. Additionally, advanced technologies such as differential steering, single-handle or steering wheel steering control have revolutionized how operators handle the equipment. As such, handling comfort of crawler tractors is becoming better by the day, and it is fast catching up with its wheeled counterparts.
6. Utilization rate and maintenance convenience
Crawler tractors are not just limited to field operations, but they can also contribute to the development of farmland infrastructure and small water projects. By installing a blade on the tractor, it can be transformed into a versatile tool for excavation and leveling of earthworks needed for agricultural or water management projects. The diverse use of crawler tractors can significantly cut down the cost of maintaining and enhancing rural infrastructure while also aiding in the economic growth of such areas.
The crawler tractor is a versatile piece of machinery that can be used for various agricultural earthworks such as cleaning fish ponds, ditching, and slope ladders. Its comprehensive utilization rate surpasses that of wheeled tractors. The full frame structure of the crawler tractor allows for easy repair and maintenance, unlike the frameless structure of a wheel tractor, which requires disassembly for maintenance. This feature greatly facilitates daily use and ensures that the machine does not have to be dismantled to carry out minor repairs.
