After pulling my mower out yesterday I noticed while mowing it was starting to slow down. Let off on the pedal then pushed back down and it seemed to work fine. It keeps doing this so I stopped and called the dealer who said to check the drive belt and the splined pulley. It is up under the seat area so I'm not able to see it very well.
Has anyone else had this issue and if so what did you find to be the problem? I did check the fluid level at the gear box and when I removed the plug it actually started flowing out like it was over full??
