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.
