GST Biostar
Multi-purpose rotary hoe designed to improve soil health, boost fertilization efficiency, and enhance farming productivity.
Built for Precision and Performance
GST Biostar is designed for weed removal with minimal impact on surrounding crops. Its star wheels uproot weeds at a depth of 2–4 cm (0.8–1.6 inches), protecting deeper-rooted plants and ensuring clean rows without chemical input.
The stable, balanced frame maintains full ground contact across uneven or compacted fields – no support wheels needed. Its gentle tilling action breaks up crusted topsoil and improves soil aeration, enhancing water absorption and creating a healthier start for emerging crops.
Ideal for both organic and conventional systems, GST Biostar also prepares clean, aerated seedbeds for cover crops. When paired with our back seeder or front tank, it allows for accurate and effective cover crop planting in a single pass.
Easy Transport & Folding Design
GST Biostar features a hydraulic folding system that allows for quick transition from full working width to a compact transport position. With a transport width under 3 meters, it meets road regulations while maintaining a large working capacity in the field.
Designed for farms of all sizes, the foldable frame makes road travel safer, storage more convenient, and transport more efficient – all without compromising durability or in-field performance.
Optimized for Speed
Engineered to handle faster passes while preserving field quality.
Durable Build
Built with high-quality materials for durability to withstand tough conditions.
All-Terrain Use
Suitable for different crops, soil types, and field conditions.
GST Biostar FAQs
Common questions about GST Biostar, If you need more details, feel free to contact us directly.
What makes GST Biostar different from traditional rotary hoes ?
Unlike traditional rotary hoes, GST Biostar features a support-wheel-free design that ensures superior ground contact and reduced maintenance. Its unique star wheel configuration delivers precise weeding, soil aeration, and crust breaking.
Do I need to drive fast ?
For optimal performance, GST Biostar should be used at speeds between 15–25 km/h (9.3–15.5 mph). The rotating stars rely on forward motion to effectively remove weeds while maintaining precision.
Does GST Biostar damage crops ?
GST Biostar is engineered to target weeds while preserving crops. Its rotating stars remove weeds at a depth of 2–4 cm (0.8–1.6 inches) without disturbing crops with deeper root systems. Plants taller than 3 cm (1.2 inches) can bend and pass beneath the rotating stars without being buried by soil.
Can GST Biostar be used for cover crop seeding ?
Yes, GST Biostar works seamlessly with our back seeder or front tank to ensure precise seed distribution. As the rotary hoe loosens the soil, it creates optimal conditions for seed placement, promoting strong germination and uniform crop growth.
