    Guys, I have a 2006 John Deere 717A with around 1200 hours on it. The problem is when I engage the blades the blades are very slow to come up to speed. The belt does not squeal or there are no strange noises such as clutch chatter or anything. If the deck is up they do not seem to come up to speed at all, then if you put it down they come up to speed. Its weird. Has anyone ever seen this? Thanks guys.

    A loose belt doesn't always squeal, Check it for proper tension...... If it is in fact tight check the bolt holding the clutch on, If they loosen the clutch can separate causing a wider air gap and slippage. If both the above are tight your likely looking at a new clutch......

    I agree with Restrorob. Last spring I had a similar problem with a Dixie Chopper that had a stretched belt. The deck to motor belt would vary in tension as I raised and lowered the mower deck. I was convinced it was something more involved than just the belt, seeing as it had worked fine prior to parking it for the winter. I later figured out it had stretched out from contact with excess grease from a spindle. New belt fixed it.:dancing:
