Hi Nicholas and also Mod CJ,
Firstly a warm welcome from myself to the ODK Repair Forum.
What you have there is a very early series 2 (twin railer) model 45 that's displaying the first lot of twin ID plates fitted over the top of each other. These are the last of the brass ID plates before swapping over to Aluminum, also your Kirby HK25 sports the larger fuel tank which was mostly fitted to the higher powered HK30 3HP model power plant, but certainly is original and looks far better than the smaller unit.
I very much support what CyberJack has suggested and that is what do you intend to use the mower for ? (cutting grass I hear you laughing), but what we are referring to is if you intend to use it as a daily driver or more of a show piece restoration ?
As far as getting the edger pulley off, just put a rag around the PTO shaft to protect it and use a pair of stillsons over the rag to clamp the shaft and then use a spanner on the lock nut that holds the pulley on and turn in the opposite direction to undo it.
Hope this helps.
Cheers,
BB
