Your picture is of an early seventies Ford by Jacobsen.
It would be an LGT 100, 125, 145 or an LGT 165.
Depending on the engine horse power. If it has a ten horse it should have a gear drive not a hydro. Ford used the same model designation on the next model Tractors from the late seventies. Yours is an open side model.
The later ones are referred to as closed side models. All open side LGT"s used the same hood. Unfortunately, whoever added those numbers to the data plate did not get the right. The O9JC number would be for the mower deck.
The model number should have been 32XX.
Those are great tractors. I have two. It"s worth getting a hood.
