   We are having some issues with our 2010 Toro 4500D mower. Over the past several weeks, it seems our 4500D is leaving a whole lot more clumps primarily in the mornings.  The engine RPM sounds about right, but it almost sounds like the decks are not at the same RPM they used to be.  When you follow the mower you can just see the clippings hitting the rear part of the deck and just dropping straight down.  All the blade motors seem fine.  I have only had this mower for  couple years so we are still learning all the components.  Any ideas or suggestions?

   Before assuming something bad, has all the PM been done at the proper times? Something as simple as a filter can cause this. Are the blades sharp, is the grass growing faster than usual? If it's the growth slow the mow speed down some. Has cut height been lowered? The clumping can be caused by several seemingly small things all happening at the same time. Use the kiss method to figure this out.

   How many hours? Very common for deteriorating relief valve o-rings to cause that after x amount of hours.
