Accessories

Reverse gear

An optional reverse gearbox allows the Silo Twist DONAR to be used with both front and rear PTO, extending its range of applications. The system automatically adjusts rotation direction and speed to match the PTO output, ensuring consistent and reliable performance in all conditions.

Pivoting device

The pivot point positioned close to the three-point attachment allows a wide lateral offset and smooth movement away from the silo wall, reducing the risk of collisions and material damage. A dual-cylinder pivoting system ensures stable operation, while a locking block prevents unintended movement and increases safety during both work and transport.

Wide-angle PTO shaft

A standard PTO shaft is sufficient for most applications, thanks to the pivot point positioned close to the three-point linkage. In specific cases, such as tractors with higher mounting points, a single-sided wide-angle PTO shaft may be required and is available as an optional accessory for the Silo Twist DONAR.

Road lighting system

Optional road equipment improves visibility and safety during transport, especially for larger machines. The system can be quickly and securely attached, ensuring safe operation on public roads, including in low-light conditions.
