Mounted disc harrow Occitan series

semi-mounted2-sectionwith hydraulic adjustment

Overview
Occitan is a shallow stubble independent disc harrow engineered for high-capacity stubble cultivation and residue management. It is designed to reduce operational costs by processing large quantities of plant residues while offering easy depth control and integration with seeders for improved agronomic results.

Key points

• Non-stop spring-loaded safety with 2 discs per arm for uninterrupted operation.
• Large-diameter self-sharpening discs (Ø 620 mm) aggressive on residues.
• High underbeam and gang clearance to prevent clogging with heavy residues.
• Heavy-duty frame for high resistance in continuous use.
• Multiple roller options (8 types) to achieve different surface finishes and consolidation levels.
• Continuous hydraulic roller adjustment (standard on semi-mounted models, optional on mounted models).
• Depth is adjustable from the tractor cabin via roller control for simple operation.
• Side disc deflectors to direct soil flow (left deflector standard, right optional).
• Following harrows to level and channel soil before and after disc gangs.
• Maintenance-free bearings with reinforced sealing and lubrication; 3-year bearing guarantee across the Occitan range.

Agronomy benefits

• Residue decomposition: Evenly distributes crop residues and mixes organic matter into the surface layer to aid soil organic matter dynamics.
• Self-seeding management: Shallow passes (≤5 cm) lift and expose seedstock to promote germination; a finishing pass can reduce surface seed bank by ~40% depending on roller and moisture.
• Pest control: Mechanical action and surface drying destroy adults and eggs of surface pests (effective against slugs and surface insects).
• Soil warming: Aeration and moisture redistribution accelerate warming and support rapid germination.
• Soil–seed contact: Improves contact between seed, soil and moisture for reliable emergence and vertical root development.
• Erosion control: Disc and roller combinations structure the surface, break crusts, increase infiltration and create mulch/micro-furrows to limit erosion and evaporation.

Working part in detail

• Two disc types: large notched discs (Ø 620 mm, 6 mm thick, curved, self-sharpening) and mulcher discs for cutting and mixing residues; notched discs perform in heavy-residue conditions.
• Two discs per arm with 230 mm spacing; staggered arrangement increases clearance and visibility.
• Non-stop spring-loaded safety: release from 350 kg, peak resistance 420 kg at 10 cm, decreasing up to 18 cm to allow continued penetration and limit frame stress.
• Generous underbeam and gang clearances to avoid clogging: gang spacing varies by model (Occitan 50/60: 950 mm; T60: 1100 mm; T70: 1350 mm). Underbeam clearance: 725 mm.
• Up to three following harrows can be fitted to regulate soil flow between gangs and ahead of the roller for a leveled finish.
• Hydraulic roller adjustment standard on semi-mounted models and optional on mounted models; roller depth control accessible from the tractor cab.
