picked up 1968 simplicity sovereign with variable-speed trans. no engine and the tractor was disasembled. the previous owner bought it, drove it around, and then pulled the engine and hydro lift off.
i have extra engines. i would like to fix this one up.
also he threw in a newer sovereign parts frame, and a set of nice rear case rims & tires.

Perry,
What engine and size did these have originally? It looks like another nice project for you. But, it is the wrong color.

my old landlord is a 10hp and this sovereign is a 12hp briggs.
i just happen to have a 12hp out of a wards on the shelf .

Nice one perry , good for you ,just keep the piccys coming .
wes

Perry looks like a good knock down model you found there.
Just curious...so many of the hydro GT's used the Sundstrand hydros...is that what Simplicity used too?
