I replaced the blades on my toro with some gators, It had the origional toros on it. The blades are pretty much the same, but the toros had a slight bend in them which made the cutting edge sit about 1/2" lower than the straight gators. Now it seems like they don't lift the grass where the front wheels went and after a day the grass is higher there. Could I add a couple washers to the top of the blade to space it down and try that? Or would that be dangerous? jim.
