Custom Flail Mower 3D Design

I am seeking a skilled designer to create a complete 3D model of a custom flail mower intended for mulching potato leaves. The design should be production-ready and compatible with CAD and CNC formats, with all necessary technical details for manufacturing.

Key Requirements:
- Develop a 3D model and renderings of the flail mower
- Include all part dimensions clearly labeled
- Provide technical 2D drawings and exploded views
- Suggest design improvements and suitable materials
- Deliver export files in STEP, IGES, STL, DXF, DWG, and native CAD formats
- Ensure compatibility with CNC and fabrication processes

Specific Features:
- Adjustable cutting height for versatile operation
- Use of steel for the main components to ensure durability and strength

Ideal Skills and Experience:
- Expertise in mechanical design and 3D modeling
- Proficiency in CAD software and CNC-compatible design
- Experience in designing agricultural machinery or similar equipment
- Ability to provide material recommendations and design improvements

Please confirm your timeline, cost, and any additional requirements needed to start the project. I look forward to collaborating on this innovative design. Thank you!
