Mounted rotary tedder SPIDER A 400|4 ALP

with gauge wheelswith hydraulic adjustmentfolding

Product overview
The four-rotor rotary tedder SPIDER A 400|4 ALP is designed to spread and turn forage evenly across the swath. Its rotor configuration and inward-folding outer rotors reduce transport width and enable operation in hilly and mountainous terrain.

Key features

• Hydraulic rotor folding: allows folding/unfolding of rotors from the tractor for simplified handling and transport.
• Pivoting 3‑point linkage: improves manoeuvrability and tractor following.
• Adjustable spreading angle: spreading angle adjustable from 12° to 18° (typical working range 14°–18°) to suit forage volume.
• Adjustable wheels and rotor height: wheels shift for edge tedding; rotor height adjustable with flexible hitch.
• Flat-steel spring tine holders: provide consistent spreading; tines of different lengths help protect the sward and deliver clean forage.
• Inward-folding outer rotors: reduce transport width and increase transport safety.
