Welcome!
That model was never sold in the US but the same thing was sold here as the Massey Ferguson 1030 and I think also as an Allis Chalmers.
Owners loved them but there were never many sold here so if someone needed parts, it might take a while to obtain them. I think most parts were available here through Massey Ferguson parts channels.
The Massey Ferguson forum here might have someone who can give you specific advice.
I just Googled 'Hinomoto E2304 Massey' and found several discussions of your tractor that might answer your questions.
