Snowblower Attachment HELP!!!

I have a 1995 Yard Machines 690 16HP series tractor, specifically a M/N 135O695G000 making it a 1995. I picked up a 190-491-000 36" snowblower attachment in great shape. I know by looking at the manual for my tractor that this is the right snowblower for my tractor. I got the channel assembly attached with the drive belt around the PTO. The belt seems too tight. I mean it seems right for if the deck was lowered(for when the snowblower would be engaged), but went I raise the lever that should lift the snowblower and disengage the belt) the belt doesn't loosen up enough to allow the belt to stop grabbing on the pulley's. I haven't attached the snowblower part yet only the channel assembly. At this point I know as soon as I started the tractor the pulleys in the channel assembly would be turning. I tried adjusting the ferrule which should allow adjustment for this issue, but that too doesn't do enough. My only other guess is that when I do attach the snowblower to the channel assembly that if will effect this. But that to me doesn't make sense. I would think you should be able to detach the snowblower but leave the channel assembly there and the PTO not turn the pulleys on the channel assembly. I tried looking at different year snowblowers to see if there were different size belts but they all seem to be the same. Looking for somebody to help that may have this same setup or has seen this before.

The only advice I may give you is it is probably the right blower but wrong belt.

I have a Cub Cadet with the Fast Attach plate that attaches my MTD blower onto the bottom of the frame. It fits several tractors besides my Cub LT1050, but to use it on some of the others I would have to put an additional pulley on the plate and use a different belt.

I may be right and I may be wrong, but I would route a piece of small diameter rope around the pulleys with the PTO off and mark down the length (after loosening the adjustment back to where it was a little loose). Then do the same with the PTO engaged. That would give you at least an idea of the belt length you would need to fully engage the PTO and have it run, but also the minimum it would take to get it to disengage.

I also forgot to say, check your routing. Its possible to get it routed just a little wrong and have it come up short, but still work or be longer and not want to work at all. Just a thought.
