Our 1941 built Fordson N type was 27 BHP, used until 1971,Dad replaced
it with a grey Fergie but that was a Diesel version.
Didn't they fit a 3 cylinder Perkins?

The original grey fergy had a 4 cylinder petrol engine that was based
on the same engine used in Standard cars, because they made them
in the beginning (AFAIK). Later ones had 4 cylinder diesel engines.
The diesel version had an interesting starter button. You had to
press a brass plunger, on the side of the gearbox with your right
ankle, and then push the gear lever into a special position.

When Massey Harris bought the company, the later Massey Ferguson 35
and 35X had 3 a cylinder Perkins diesel engines.
