    I ran over a small cut down sapling stump and shut down mower... I could tell that something was different was barely discharging the grass clippings..and sounded different. I changed the blades and one shear key and didnt see anything else wrong...It did not fix the problem..

    Do the blades all rotate together or independently I dont remember them turning independently like they do now... what could i have broken.. thanks in advance..

    I have a hustler Z 23hp kaw w/60" cut.....It is not a motor problem at all It happened when I ran over the small tree stump.. They blades still turn but something is definitely wrong. It sounds like they speed up an then slow down and speed up and slow down...and the grass does not discharge very far..

    I changed the blades but something is still wrong...
