Twister B4 'Bucker' Debudder 

Bucking is a huge hassle. But the Twister B4 “Bucker” takes the hassle out of the debudding process by making advanced, patent-pending bucking technology available to your work flow. Designed and engineered using only top-quality materials, the Twister B4 bucking machine delivers continuous, dependable performance even under the most demanding conditions. The B4 is built to be flexible so you can use it on a table, stainless bench, accessory stand, or on your truck’s tailgate! The B4 was meant to work in any size grow operation that requires high-quality equipment without risk of downtime or machine failure.

With Twister’s “Swappable Cartridges” the B4 lets the operator remove and replace the bucking cartridges in moments, reducing downtime to keep your harvest rolling along. When you need to switch strains or it’s time to clean up, simply change to a clean, QA-approved cartridge and you’ll be back up and running in a flash. No need to have multiple machines waiting to be used while the others are being cleaned.

The B4’s “Active Gearing” is Twister’s patent-pending drive system that allows the Twister B4 bucking machine to adjust to the varieties of stem sizes to help mitigate downtime due to jams, clogs and other issues that result from feeding stems under other fixed roller designs.
