I have a Craftsman 917-28857 46" Riding Mower. (YT4000) It only has 30 hours on it and I recently decided to add a Mulching Kit to it. I installed the mulching blades and now every once in awhile a can hear a tink noise like I am hitting a rock. It looks like the one blade is hitting the deck depending on where I am at in my yard. The blades were brand new out of the package so I know the blade is not bent.

Anyone encounter this before? Should I just try to uninstall and install the blade? Is it maybe something to do with the deck (which I did not touch). The regular blades I was using never had this issue.

Take a look at the blade as well as the deck and look for shiny spots that looks like something has be hitting. Sometimes grass clumps going through a mulching deck can back some weird noises also.
