Hi Jason, this machine was made in New Zealand by Morrison mowers and badged as a Scott Bonnar. It shares some of its heritage with the Victa Imperial. Its reel assembly is manufactured by Ransome (of which we have no information, as yet)
As I said in my previous post, it will be a learning curve for all of us.To answer your question specifically, I haven't got a clue, mate!
However, with Chris's help and pics, once the unit is disassembled, we may figure out how it is adjusted.
This will make a very informative archive.
