Thank you for the photos Rod. My Brake drums do appear to have a ring nut ( got a lot of grease to clean up on one side and rust on the other) but there are also holes in the brake drum which I wondered if they were for pins or something. I have had other people talk about 6 bolt pattern but no one knows what I am talking about with the nut. The nut would appear to require a special spanner which I will probably have to fabricate.
I do need to fabricate up some stands to make jobs like that a bit safer I did have a couple of props in whilst I was unbolting the front but had to get them out the road so I could roll the front end out.
Cheers, Nathan

I think that the drums are a press fit onto the shaft with a keyway. Can't see any 6 bolt holes as yet but may turn up after a clean. Our Cropmaster is a press fit onto the end of the main axle and was a case of using 'jack bolts' to wind it off the axle and is why I mentioned those 2 holes in the drum. Are they threaded by any chance?

Nathan, I can not see any nuts. The brake drums are pushed onto a splined shaft, some of which is protruding from the drum. According to the parts book there is no locating device, such as a circlip, so probably just a tight fit. I have not had one apart. The shaft is hollow, and is sealed with a Welch plug. The drums appear to have threaded holes in them for extractor bolts. Screwing long threaded bolts into the holes may push the drums off. There should be solid enough cast iron behind the drums for the bolts to push against.
