Here's what I have found.

E 067 = No PTO installed at the factory.

G 047 = 18.4-34 rear tires

H 086, I haven't been able to find, but it is the code for the rear wheel centers. Between this code and the PTO code, was this tractor built as an industrial?

A 403 is the style, that wasn't listed in the price sheets. I'll have to compare it to some others to know for sure.

B 007, probably the gas engine. I'll look into that more.
