    Dan,

    According to the book, the blades should be perpendicular (90 degrees) to each other. One straight up and one straight across. If you remove the cover and look closely, you’ll see a small lever on the RH spindle. Loosen the four RH spindle bolts and use the lever (pull back toward operator) to tension the timing belt, then retighten the spindle screws. The manual says “moderate tension 8-12 lbs or about a half inch deflection at the midpoint).

    Hope that helps.

    if it's timed right them maybe you could have a blade hitting the deck somewhere?

    Danzo,

    If you can't find the lever, or if it has been removed, you can still adjust the belt. The important thing is that the Right Hand spindle uses slots to mount. The LH uses round holes. The slots are not very long (or the blade can be moved over and hit the deck) but should be long enough to get the proper tension.

    Loosen the foru RH spindle mounting bolts and "Pry" the spindle outboard as far as possible, hold it and retighten the bolts. That's the best you can do.

    If you have a new belt the only other thing to do is look closely at the sprockets to make sure they have all thier teeth. If they have all their teeth and you have a new belt and it still hit's, I'd call the factory service department.

    But don't let the blades it or you'll do a lot of damage.

    Ohh -- are the blades level or has the deck been bent once before?

    Good luck!

    Is it a cogged (timing) belt or just a regular V belt? If it is just a regular V belt the blades are to long for your application. The only way blades will stay in time is if it is using a cogged belt with cogged gears the way the OLD Cub Cadets used to do back in the 60's. Normally decks are set up with the blades a little offset (one farther forward than the other). Than you use blades that will litterally over lap but won't hit unless they are too long.

    I realize I am reviving a 6 year old thread but I just used this that I found through the thread search to fix my 33 wb that just destroyed a set of blades. This saved me alot in shop fees and I kind of enjoyed working on my own stuff anyways.
