Rotavator Benchmarking and Reverse Engineering
Project Scope
- Phase 1: Market Study & Competitor Analysis
- Phase 2: Reverse Engineering, Design Verification, & Drawing Preparation
- Phase 3: Prototype Build Support
- Phase 4: Field Reliability Testing
- Phase 5: Spare Parts Catalogue Development
Business Challenges
- Determining the appropriate chain/gear reduction ratio for the primary and
secondary drive, with calculations for the required RPM (214 RPM with a
20-tooth and 19-tooth gear combination) for 55 HP PTO tractors with a 42-
blade configuration - Selecting the correct flange size and spacing to accommodate various
blade types available in the market, ensuring a cutting depth of 7 inches
(170 mm) - Customizing components based on customer requirements and addressing
field failures
ARi’s Solutions

drawings for prototype build (140 units within 1 month) - Provided support for prototype build issue resolution and testing
- Developed packing drawings for the gearbox, stub axle, and side door
- Updated CAD models and drawings based on feedback from prototype
build testing
ARi’s Value Proposition
- Accelerated product launch with 140 prototype-ready units delivered in 1
month - Reduced equipment weight by 50 kg, improving efficiency and
transportability - Enhanced reliability and performance, minimizing field failures and
maintenance - Enabled product customization for diverse markets, expanding customer
reach
