I can't answer your specific question, but I would encourage you to post this question in the Chinese Tractor forum further down the page. It is likely that someone there could help answer your question.
Go to TractorData.com - information on all makes and models of tractors and it will show you exactly what you want to know. It will either be a Massey Ferguson or Allis Chalmbers, I can be pretty sure of that. When you call them, ask for their specific model number, not the Hinomoto one and take your old one to match...
