I don't have a blade so I can't compare the two. Deere part number for the bed lift is AM138797. JDParts.com doesn't even list a part number for the cylinder on the blades.... I'm down to comparing the manufacturer's sticker on the side of my bed lift cylinder to your blade cylinder....

Hope this helps a little...and hopefully someone else will pop in here and reply with more info!
