Last Fall I put a longer blade on the driver side of my EA82. I used a 17" on the right and put a 19" on the driver. There is room to do it. The thing was that it seemed to drag the motor down a bit and chatter more easily.

 

This Fall I put an 18" on the driver but dropped to a 16" on the passenger. It works fine, no chatter, no drag. I was thinking that I could probably have used the 19" again, with the other side reduced. It is nice to have the larger swept area on the driver side.

I Use both sides 18" on both my Subies... Larger Blades seems to Fail to Rub in their tops due to the Windshield's Glass Curve.

 

Kind Regards.
