Rescued a Scott Bonnard reel mower model 590 from a roadside collection and with a bit of TLC have managed to get it going pretty good. I'm a novice when it comes to reel mowers so I have lots of questions to ask the gurus out there. For this post, I would like to find out more on the height adjustment for this model. I have included photos.

I assume that the height adjuster is the item in the bottom right corner on my photos. There is a plastic cover with circle marks on it which screws onto a thread. There is also a metal flange which looks like a '3 leaf clover'. Which of these items needs to be turned/screwed to affect the height adjustment? I have tried turning both clockwise & anti-clockwise but seems to have no effect on the height adjustment. Maybe it's not working/busted and I need to get creative and find a workaround? It looks like the height adjustment is linked to the roller at the front - raises or lowers the roller - is that correct?

I look forward to any feedback.

Cheers
Pat (Carn the PIES !)
