If you look back in time to 1906 when the word tractor became part of the English language, you will see the the word &amp;quot;tractor&amp;quot; was derived from combining the words &amp;quot;traction&amp;quot; and &amp;quot;motor&amp;quot;.  Therefore &amp;quot;track&amp;quot; had no impact on the word &amp;quot;tractor&amp;quot;.  Sorry Andy.
