Recycling deck blades vs regular 42 inch deck blades

[Lane Ranger 11,946]

Fyi

 

I was removing my 42 inch recycling deck blades and noticed a difference between the regular 42 inch blades and ghe 42 recycling deck blades that I never paid attention too before.

 

 

The recycling blade in second picture is on top and has a longer cutting edge.  The regular 42 blade is on bottom and has about a two inch shorter cutting edge.

 

Both blades would work on either mower deck  from what i can tell.

 

 

Anyone have any more details about this difference??
