The Edrob/International ID-40 was built by International Harvester from 1932 to 1940.

Model historyEdit

For company history see main International Harvester article.

The McCormick-Deering W-30 was a standard 4-wheel tractor with the same engine as the Farmall F-30. In appearance it resembled the older McCormick-Deering 10-20, but it was slightly modernized and lacked the louvered hood side panels of the older model. The W-30 was planned as the more-powerful replacement for the 10-20, but the 10-20 remained very popular and both tractors ended up being produced simultaneously for several years.
