Ok ...i know im opening my self up here because this is a dumb question .....but which way do the blades go? I recently bought a set of JD high lift blades for my 445 with 54 inch deck the parts guy told me to make sure i installed then correctly he showed me where JD stamps the part number into the blade he says this side goes up toward the deck ...ok i went back today and got another set of high lift blades for my 425 with 48 inch deck a different parts guy told me just the opposite he says the part number should face the ground? ? Is there a easy fool proof way to know? Go easy on me im new remeber....

The cutting edge should go away from the deck on normal blades. I have never used high lift blades so I don't know why HL blades would be different. IMHO.

Lex, If everyone knew everything there wouldn't be any place for all us guys to hang out and feel smart. The blades have a cutting edge and a curved lip. the curved lip should face up toward your mower deck. An easy way to tell is turn you deck on to see which way the spindles turn. Which ever way the spindles turns that is the side the cutting edge should face and turn.

The blades on my Poulan are marked "Grass Side" to help you install them correctly. JD blades are not. High lift blades are just like a little propeller. The curved parts of the blade and the ground beveled cutting edge should be facing up towards the underside of the mower deck.

Or, you could try my neighbor's plan. Just put them on and mow for a couple years and see whether you are actually cutting the grass, or just more or less blunt-force trauma-ing the grass into submission. Is there a good way to tell a neighbor he has his blades on up-side-down?

Yeah but at least he'll never need to sharpen his blades!:00000060:

Right after you ask if he made sure to change the winter air back to summer air in the tires. I love to pull that one!
