Over the last decade, a vital product in the domestic agricultural machinery market has been overlooked and forgotten. The crawler drag was not given its due importance until recently when an analysis of the subsidy problem related to it surfaced on the internet. To be honest, even the author had forgotten about the crawler drag until this recent analysis. However, the crawler drag is making a strong comeback, and here is a breakdown of what it entails.
Conservation tillage and being irreplaceable are two key benefits of crawling. This farming method can help preserve soil quality and reduce erosion, leading to improved yields and long-term sustainability. Furthermore, the unique ability of crawling to access hard-to-reach areas can make it an essential tool for farming operations. Overall, crawling offers a range of advantages that can make it a valuable asset for farmers seeking to optimize their operations.
Back in the day, the author didn't have to use too many words to get their point across. However, these days many individuals are unaware of certain terms, like "dragging". As a result, it's essential to reiterate the same ideas and refresh people's memory.
In order to protect the soil, the pressure of the grounding ratio needs to be kept low.
To prevent the formation of plough bottom in dry land and ensure that there is enough moisture to prevent drought, it is recommended to use crawler and towing operations. In paddy fields, it is crucial to prevent damage to the hard bottom layer, which can impact the normal cultivation process. Tests have shown that the specific pressure of wheel trailing ground is three times that of crawler dragging, resulting in a seedling emergence rate of only 30%-40%. However, opting for crawler dragging can maintain a seedling emergence rate of 80%-90%. Lastly, tugboat ruts in paddy fields can have a significant impact on rice planting and harvesting, leading to deeper mud feet and an inability to cultivate.
The benefits of deep turning load operation are quite evident, especially considering the significant traction force involved. This means that the force applied to the machine is significant, leading to more effective and efficient turning.
According to research, the traction force of a crawler tractor that weighs the same as a wheel tractor is 1.4-1.8 times more powerful. Furthermore, the traction efficiency of a wheeled tractor ranges between 55-65%, whereas the crawler tractor can reach 70-80%. Therefore, it can be concluded that although both tractors have the same horsepower, the effective power of the wheel trailer engine is lost by 15% more than the crawlers, making the latter more efficient in terms of traction.
Dragged by a wheel, the operation efficiency is 0.5kg to 8 taels.
The speed of tractor operations for farmland depends on the task at hand. For rotary tillage, the speed usually ranges from 5 to 6km/h, while ploughing operations have a speed range of 7 to 9km/h. Raking operations require a higher speed of around 10 to 12km/h. When it comes to tillage speed, there's not much difference between crawler dragging and wheel dragging. Both provide similar speeds and traction advantages for various farm operations, including plowing, raking, and sowing. Whether using wheels or crawlers, the speeds are comparable, and there's no significant difference in terms of performance.
4. Strong passability and climbing ability
The crawler tractor boasts a remarkable slope stability owing to its low center of gravity and high adhesion coefficient, which significantly minimizes the risk of overturning and sliding. Besides, its maneuverability is impressive, thanks to the small turning radius, and the cross-country capability is unparalleled due to its robust climbing ability, rendering it ideal for use in farmland and terraced operations in mountainous and hilly areas. Additionally, the machine is a top-tier all-terrain operating machinery, particularly after fitting it with rubber tracks.
