John Deere customers in both commercial and residential mowing dislike the amount of time and effort it takes to remove the mower blades in order to sharpen them. Blade sharpness is important in maintaining the health and appearance of the cut grass, but it is a hassle to use tools to remove lawn mower blades and then put them back on after sharpening.

Deliverables

Propose a rotary blade design which allows for easy removal and attachment, but can also sustain the stress of frequent mowing. Attach sketches, mockups, or design drawings showing the attachment methods of your mower blades. Additionally, include a written description of your blade removal system to explain how it functions. Submit your design in PPT, PDF, or JPEG formats.

Avoid any ideas that have already been filed for U.S. patent. Focus on making your solution cost-effective and easy to implement.
