I took my JD 727A yesterday to the dealer. The eye bolt that the belt tension spring hooks to was about rubbed all the way through. Its under warranty. I've only got 78 hours on it. I asked them about some blades and they gave me a price of about $21-$22 per blade. I side discharge and I was wondering where I should try to get blades at? Last year when I changed them I didn't remember them being that high.
