I have an Alroh 20" mower which I am guessing must be at least 40 years old. It goes well and I am wanting to remove the reel so I can take it in for grinding. I am having trouble figuring out how to remove the reel sprocket in order to remove the reel form the chassis.
Some pictures attached for reference. Is this a threaded sprocket perhaps? If so any suggestions as to how to remove as it seems to be locked on nice and tight!
