It is recommended to provide a minimum output power of ≥ 100hp (75KW). The 9YYZ-1250 round hay baler uses 2 active driving rollers, 16 driven rollers, and 18 high-strength steel rods in its baling chamber. It is suitable for baling wheat straw, rice straw, corn stover, and various types of forage. It can maximize compression rate and improve rotation effect under various conditions, making the package shape beautiful and compact. Even under harsh operating conditions, it can achieve excellent product quality. The design of the hydraulic system regulating the bottom door ensures the high-speed and stable operating efficiency of the baler, providing safer and more reliable operational support for the operator. At the same time, the handheld Always HMI device has a simple interface and is easy to learn. It can complete the setting of bundling operation technical parameters such as bale density and number of winding circles. It can also easily view the working status of the baler and record the number of operations, making bundling operations easier.
