• Frame Assemblies: Side panels, middle frames, lighting brackets, perforated plates, and structural supports.
• Bearing Assemblies: Flanged bearings, circlips, washers, and bolts for roller and axle support.
• Axles and Wheel Assemblies: Separate listings for Vitu 300 and 400 center and side frame axles, including universal joints, lockpins, wheel nuts, tyres, and axle tubes.
• Brake Systems: Mechanical brake shoe assemblies, hydraulic brake cylinders, compressed air brake components, relay valves, safety valves, hose assemblies, and brake proportioning valves.
• Seed Metering and Soil Preparation: Leaf springs, toothed discs, levelboard holders, tram liners, seed hopper frames, dosing devices, and safety screens.
• Electrical and Lighting Systems: Front and rear LED lighting components, wiring harnesses, connectors, switches, and seed flow control modules.

3. Technical Specifications and Parameters

• Fasteners: Metric sizes from M6 to M22, strength classes 8.8 to 12.9, zinc-plated or stainless steel finishes.
• Washers and Circlips: Defined dimensions (e.g., U-washer 60x36x3 mm, hardened washers 17x45x6 mm) for secure assembly.
• Lockpins and Spring Bushes: Dimensioned by diameter and length (e.g., 28/105/138 mm) for precise fit.
• Bearings: Conical roller bearings (30207, 30215, 32211), SKF bearings for durability and smooth operation.
• Tyres: Standardized size 240/75-17.5 with 6-hole rims and ET0 offset.
• Hydraulic Components: Pumps (NPH-51RAL 7021), valve blocks with electronic switching, load holding valves, pressure filters, and quick release couplings with specified torque values.
• Electrical Components: LED lighting systems with mounting hardware, cable harnesses with ISO-BUS compliant connectors, and seed flow control sensors.
• Seed Metering Wheels: Cellular wheels with groove widths from 15mm to 60mm for different seed types.

4. Notes and Validity

• Parts lists are valid for machines manufactured from 2018 onwards, with some components specific to production years (e.g., lighting systems before and after 2022, air ducts before and after 2019).
• Ordering instructions emphasize specifying hose lengths in meters for hydraulic and air duct hoses.
• Multilingual descriptions facilitate international use and accurate part identification.

5. Recommendations and Best Practices

• Always use exact part numbers when ordering to ensure compatibility.
• Observe specified bolt grades and torque settings to maintain structural integrity and safety.
• Ensure proper installation of locking devices such as castellated nuts with split pins, lockpins, and retaining rings to prevent loosening.
• Follow hydraulic plans and bleed hydraulic cylinders and hoses before installation to avoid air entrapment.
• Regularly inspect grease nipples and lubrication points, especially on brake axles and bearings.
• Use specified washers and spring bushes to enhance durability and reduce wear.
• For electrical systems, install wiring harnesses with correct connectors and protective casings to maintain system integrity.
• Maintain seed flow control systems with appropriate sensors and numbering sets for accurate monitoring.

6. Summary of Document Structure

• Multilingual parts lists organized by machine assemblies: drawbar, frame, bearings, axles, wheels, brakes, hydraulics, electrical, seed distribution, and soil preparation.
• Detailed technical specifications for fasteners, bearings, hydraulic components, electrical systems, and seed metering devices.
• Assembly instructions and notes on machine-specific configurations and production year applicability.
• Tables summarizing key components by section, highlighting functions and critical parameters.
