I started building an RC lawn mower, using a powerchair for the base. Unlike many you may see on YouTube. I am making it with tracks for the base unit. The lawn mower will be attached to one end of the base and pushed or pulled when mowing. (See image 1.0 )

Then I started thinking about other ways the base could be used. I have to use a box scraper for my gravel driveway. I could drag that with this base unit. So instead of pushing the lawn mower, I could make a lift for on the one end of the base unit that the lawn mower could connect to. Then when needing to drag the driveway I can change out the lawn mower for the box scraper and drag it.
As of 8/12/2021 this project has not been complete. But I have lots of pictures of what has been done so far.
