With extensive experience, several techniques can be applied to significantly reduce fuel consumption and operating costs when using a cultivator in paddy fields. These methods not only improve efficiency but also ensure better performance and safety during operations.
First, try to use the "fast" gear whenever possible. If the field size is suitable and there are no obstacles like ditches or pits, the operator should consider using the high-speed gear. This involves increasing the throttle to a higher, yet appropriate, position so that the engine speed approaches or reaches its rated level. However, it's important to slow down when turning to maintain control and avoid accidents.
Second, maintaining an optimal cultivation depth is essential. The depth should be moderate—typically between 10 to 12 cm for paddy fields. Going too deep increases fuel usage, reduces comfort, and raises operational costs. At the same time, the width of the tillage should be maximized to take full advantage of the soil’s natural tearing effect. A width of 24 to 26 cm is usually ideal. Too narrow a width reduces efficiency and increases fuel use, while too wide a width may cause gaps between furrows, leading to poor results. To achieve the best width, make sure the wheels are close to the unworked areas of the field.
Third, keep the cultivation depth and width consistent throughout the operation. Try to move as straight as possible, and if you notice any deviation, correct it immediately. It helps to choose a target at the far end of the field and focus on maintaining a straight path. For irregularly shaped fields, it’s best to cultivate them gradually until the surface becomes smooth and even. Avoid placing your feet on the lifting pedals of the equipment, as this can interfere with depth control and lead to uneven tilling.
Fourth, operate the throttle gently and avoid unnecessary idling. Keep the machine running smoothly by minimizing stops and starts. Additionally, reduce the weight on the balance board—especially excess mud—if possible. This can help lower resistance and improve fuel efficiency. However, always ensure proper weight distribution to maintain good tilling quality and stability.
By following these practices, operators can not only save fuel and money but also enhance the overall effectiveness of their farming activities in paddy fields.
