Welcome to Tractor Forum Lez!
The John Deere 2450 was a grey market tractor of sorts. It was manufactured for export to Europe and other overseas countries. Some Australian ads for sale refer to it being 70 hp. It is probably comparable to the John Deere 2440 in that respect.
I would advise you to check with your local John Deere dealer to verify if they still carry or can get parts for this tractor. Since you are in Ireland, the Deere dealer specs. and info. will be geared towards European specs.
