I have a 2001 Toro Z147 with a 17HP and the 44" SFS deck. It leaves a smaill (2.5" width) windrow about 3 inches inside of the discharge. At first I thought it was due to the rubber discharge chute deflecting the grass back. I took the chute off, same issue. The blades are Toro medium lift blades. Does anyone else have this problem? I have ordered a set of aftermarket Hi-lifts (Stens, I couldn't justify 55$ for something that may not fix my issue) to see if this fixes the problem. Otherwise, the mower cuts fine and stripes fairly well as is.
