Changed blades now belt won't tighten up?

I took the deck of my ariens yt150h riding mower to change the blades, got her put back together and now when I go to engage the blades I can see the engine pulley turning but the traction drive belt won't tighten up. Is there something simple I am overlooking? It worked fine before I took the deck off btw.

Here is the layout of my belts.

is it possible the spring came loose from the tensioner. that could be the only thing... unless you the deck is not back in the exact same location it was before the swap. even in inch off could make the difference.

Next question... why did you take the deck off?

The spring is tight on the tensioner. I'll check to make sure I put the deck back in the right position but I don't see how it could be off very much or else the pins wouldn't align.

I took the deck off to change the blades.

you should not have to remove the deck to change the blades....

the pins may have lined up but something must be off...

that diagram is not the diagram of the deck its the drive belt. is it possible the belt on the deck came loose?

stupid question I know.... but the belt is on the proper side of the tensioner pulley and the tensioner spring does put tension on the belt IE the spring is in the proper place...... if the deck belt is ok then the tension on the drive belt is the culprit... we know that the belt did not "grow" while it was off. we know that the engine side of the pulley did not move. so it's all about the tension... I know I'm, not helping much...sorry

Why would you take the deck off to change the blades. If worst came to worst and you really didnt want to go crazy trying to get it back to how it was you could just go get a shorter belt. Its got to be either the tensioner, the belt not being on correctly, or the deck is in the wrong position.

Are you 100% sure you have the right belt? Did you hold the new one up next to the old one and assure that they are the same length? Or did you just assume that it's the right belt?

So he did. It never occured to me that someone would take the deck off just to change the blades. Does he remove the engine to do an oil change?
