I built a tool a while back for starting my mower etc using my battery drill. Quite a lot of old people (like myself) contacted me looking to purchase a unit. I have developed the unit and now have a few for sale if anyone's interested. It can be seen in actions on YouTube at https://youtu.be/OuEHyDzbimg or go directly to https://www.pullstarters.com
All comnents are most welcome.
