Introduction l.jpg
Introduction

  • Project Goal:

    • Design a wheelchair lift and storage device for the John Deere Gator to make it handicap accessible and functional.

  • Prototype Criteria:

    • Modular, low cost (<$500), safe, effective, and maximize bed utility and functionality.


Assumptions l.jpg
Assumptions

  • Maximum wheelchair weight is approximately 50 lbs

  • User has use of both arms and hands

  • Used on John Deere 6x4 Gator

  • User will not have the wheelchair stored when tipping bed.

  • Folding wheelchair is used.

  • User can reach 1.5 feet behind on the driver side of the gator.
