Rotary cultivator coulter mounting method
The plowshare's coulter comes in two types—left and right—and is installed in different ways depending on the farming needs. Here are the main installation methods:
1. **Staggered Installation Method**
This is a common approach where the left and right coulters are staggered and symmetrically mounted on the cutter shaft. The outermost blades on either end of the shaft are bent inward slightly. This method uses a rotary flat surface, making it ideal for flat or level field work. It ensures even soil cutting and is widely used in standard tillage operations.
2. **Inward Installation Method**
In this setup, both the left and right coulters are bent toward the center of the cutter shaft. After tilling, a raised ridge forms in the middle of the field. This technique is particularly useful for deep tillage and allows the machine to cross over furrows and fill them in during the process. It helps in creating a more uniform seedbed and improves soil aeration.
3. **Outward Installation Method**
Here, the left and right coulters are bent outward, away from the center of the cutter shaft. However, the blade at the very end of the shaft is bent inward. This configuration creates a shallow furrow in the middle after tilling, which is beneficial for combined operations like demolition or rotary tilling. It allows for better debris management and can be effective in preparing fields with uneven terrain.
When installing the blades, always follow the correct order and pay attention to the rotation direction of the knife shaft. The blades should be evenly distributed along the centerline of the cutter shaft, ensuring symmetry on both sides. Avoid placing the blades back into the soil, as this can cause damage to the machine and reduce its efficiency. Proper installation not only enhances performance but also extends the lifespan of the equipment. Always double-check your setup before starting any operation.
