[AT] 1949 Case VAC is home.

[charlie hill]

That's right George.  The old JD's pulled a low frame on wheels that just 
skimmed over the tops of the cucumber vines.  It had seat on it so that the 
folks could sit and pick the cucumbers.  Passing by on the highway you could 
barely tell the tractors were moving.  My guess is maybe .2 of a MPH at 
best.  I didn't know the farmers so I never stopped to look at the rigs.
