When was the F-40 Introduced?

When was the Ferguson 40 tractor introduced to the market?

The Ferguson 40 was introduced in April, 1956 and produced through 1957. In 1958 the MF-50 was introduced, replacing both the F-40 and the MH-50.

The MH-50 was a source of major irritation for Ferguson dealers who rose up “en mass” demanding it be removed from the Massey Harris line along with all the Ferguson implements to go with it. The F-40 was an attempt to placate the Ferguson dealers and maintain a two line policy.
