Rotavator New Product Development

Project Scope


  • Phase 1: Market Study & Competitor Analysis

  • Phase 2: Concept Design, Brainstorming & Validation

  • Phase 3: Prototype Build & Field Testing

  • Phase 4: Manufacturing Implementation

  • Phase 5: Manuals & Spare Parts Catalogue Updates


Business Challenges


  • Selection of the correct chain/gear reduction ratio for the primary and

    secondary drive, with calculations for the required RPM (240 RPM with a

    21-tooth and 18-tooth gear combination) for 70 HP PTO tractors with a 56-

    blade configuration

  • Determining the appropriate flange size and spacing to ensure a cutting

    depth of 8” (200mm)

  • Providing ongoing support for resolving prototype build issues and

    conducting testing


ARi’s Solutions


  • Released part (sheet metal, gearbox casting, and machining) and assembly

    drawings for prototype build (150 units within 1 month)

  • Validated product design for structural strength within an accepted stress

    level of 250 MPa

  • Provided support for resolving prototype build issues and conducted testing

  • Updated CAD models and drawings for manufacturing based on feedback

    from prototype build testing

  • Updated product manuals and spare parts catalogue


ARi’s Value Proposition


  • Enabled rapid prototype delivery (150 units) to support early field trials and

    production planning

  • Reduced product weight by 80 kg, enhancing fuel efficiency and operational

    performance

  • Ensured consistent cutting depth (200 mm), improving field output quality

  • Accelerated transition to mass production with ready-to-use assembly jigs

    and documentation
