Looking for replacement cutters

I have a Ryan core aerator that needs some new cutters. Not having any luck finding them in my area. A friend of mine said to try here. If anyone can help, I would appreciate it.

 

What is the name of the Ryan aerator and do you have a part number?

GA30? Greenaire II? Lawnaire IV? Lawnaire 28? Other?

 

I don't know the name of it or a part #. The only tag that is on it says- Ryan-OMC/Lincoln,Neb. and Model # 544859-8810 Ser.#132067. Hope this helps.

 

Can you post a picture of the unit?

Other items available for this unit also, but that should give you a general idea of what you can expect in costs.

3/4" closed looks like the right ones.
