Hi, I have a Scag Turf tiger 52" cut with approximately 400 hrs. About mid season I started having trouble with the fuses getting hot and melting also it started leaving the grass partially cut especially on the right side. I have changed the deck belt, the drive belts and the clutch and it still wants to kind of lay the grass down and not cut it. I have checked the deck to be sure it is level and checked the tire pressure. It seems as if the blades are not turning fast enough. I usually use the gator blades, but I went back to the regular blades, but no chance. I also checked the mandrels and they all seem tight. I have had it approximately 8 years and have had very little trouble with it replacing only one hyd. pump and the bearings in one mandrel. If anyone has any ideas they would be deeply appreciated.
