This photograph was one in a series featured in the May 23, 1936 Pantagraph under the headline “Tractor Power and Tractor Care Growing in Importance on Farm.”This late May 1936 scene shows James Moberly (though which individual is James is unknown) of Funks Grove Township grinding valves and fitting new rings on his McCormick-Deering Farmall F-30 tractor. Moberly was preparing the tractor before his corn was ready for cultivation.
