I am fairly new to your forum, have been reading it but very seldom post I enjoy the articles. I am curious to know if you can tell me what year the Massey Harris 27 combine used the Hercules jxc engine. It is my understanding that this engine was only used one year. Also if you would know the reason why they made this switch for one year? Can you also confirm the other engine they used in their other 27s was a continental. I am restoring a cletrac that had a jxd Hercules engine in extremely poor condition and my neighbor offered me the Hercules engine out of his 27. I removed that engine about 16 years ago and I'm finally getting to the restoration on the crawler. Now my good neighbor has since passed and I never asked him what year that combine was built and I would just like to know for the record. Thank you all for any help in advance.
