My design approach is simply to help others; to give them the tools to thrive.
Final year project
Amputation and Death Prevention for Farm Workers Operating PTO Shafts
Final Design Solution
My final year project looked at redesigning power take-off (PTO) shaft guards for tractors, with the aim of preventing amputation and death for UK farm workers.
During the research stage, over 150 passionate farmers gave accounts of issues they had with traditional guards: they damage easily, are hard to use, and are ultimately not fit for the purpose of protecting workers from highly dangerous machinery.
The ‘Easyguard’ design philosophy is the ease of use; ease of installation; ease of maintenance and ease of replacement.
The clasp and hinge facilitate quick installation, while adjustable end cones make (often skipped) shaft maintenance easy.
Robust materials, modular part design and low-cost manufacturing processes make this a viable alternative to current guards.
Installation
Unlike current guards, which require a lot of steps and time to install, the Easyguard can be installed straight onto any already-installed shaft. Via a nylon bearing, the guard locks in two directions via clips, securing it in place. A metal rope connected to the tractor stops it from spinning.

Adjustable and Switchable Cones
A series of end cones can be installed onto the guard - removing the need to replace the entire guard if it's damaged, as well as offering a variety of shapes for different applications. (Implement rubber 'R' cone pictured).
To reveal the PTO shaft and universal joint for maintenance, the cone simply unclips and slides back, saving time and energy for the farmer.
