Hi Micka Sorry I forgot to tell you the diameter of the 9C diwith the blades attached was 18 inches exactly/
See you now have the (b blades and are looking for felts etc If I see any lurking about in the old boxes I will put them one side and let you know.
Went down the farm looking for a 9B disc etc but came up with a box of ealy model side covers which I have put on Ebay Also some 9C discs which will go on tohight Cheers Joe Brown
Thanks again Joe B, when I asked for the 9C disc diameter I actually meant the disk itself, but do not worry about it since I have just put my new 9B blades on my 9B disc I have found some more info.
Above I mentioned the 9B blades and the 9C blades were the same length, this is not correct, I found the 9B blades a 120mm and the 9C are 122mm. After removing the 9C blades from my mower and installing the correct 9B blades with the 3/8 hole and not 1/2inch I now have about only 1mm of blade sticking out from the mower base, so I am now happy and also happy I have it correct. Thanks Martin.
