mountedbeddingfor round bales

Product overview
The HÉLICUT is a straw blower specifically designed to produce short straw lengths, meeting the needs of livestock farms looking for uniform, comfortable, and cost-effective bedding. Thanks to its high-performance unravelling system, large-diameter turbine and interchangeable screens, it allows the straw length to be easily adjusted to suit the requirements of each operation. Available in mounted or trailed versions, the HÉLICUT combines performance, ease of use and reliability to deliver fast, precise and consistent straw spreading.
