The three images shown here were drawn with TurboCAD v9.5 Professional.  Drawing in 3D was still a fairly new undertaking for me at this point so the images may lack some of the refinement that came later.  It's always good to keep one's early work so that I and others can see that learning from experience does happen.

 

Though lacking in cosmetic appeal, the drawings do have all the necessary dimensional requirements to actually build what they represent.

 

The roller shown here is commonly used in the Mississippi Delta farming region to flatten the top of and firm up "rowed-up" beds prior to planting cotton, corn or soybeans.  The purpose of the beds is to keep the young plants above water after heavy rains and also to allow planting in dry conditions where the top of the row can be knocked off with a row conditioner exposing the moister soil that lies underneath. 

 

This version is completely generic and not copied from any other commercially manufactured roller that I know of.  This image imbodies my thoughts on how the tool should be built. 

 

The race cart frame shown at the bottom is a project that I started but never finished.  One day I will complete it.
