I am having a problem with the blades not being even with one another. It has a two blade system, which i will call "drivers side and passenger side". I am noticing that the passenger side blade is cutting at a higher level then the drivers side blade. The difference in height between the two blades when they are in line with one another is 7/8''. I have replaced the blades and the blade stiffeners hoping for a cheap fix. After putting the new blades on i noticed there is still a difference in height between the blades when they are in line with one another. Are the blades suppose to be this way? Why am i getting a different cut height difference? PLEASE HELP!!! yard looks striped only because of the cut height difference between the two blades. :confused2: example of the height difference passenger side> ----____ <drivers side

Not to insult your intelligence but. Is one of them installed upside down?

Blades are on the correct way.
I've also made sure the deck was level.

I remember there were spacers on my old scag is there any on top of the blades? If not maybe you could find a washer that was 7/8 in thick to put on top of your blade to level out the cut.

Other things to look for are tire pressure wheel height adjustments

I have thought about going the washer route. It would make sense to me just to put a spacer between the blade and the, what I believe is the spindle. I wasn't to sure if that would be safe.

Would there be a way to check the spindle bearings with out taking it apart? I have no problem taking it apart to inspect.

A difference of 7/8" usually means something is not assembled correctly. Very dangerous to try to shim the blade out, you will not have enough bolt threads to hold a blade with a tip speed of 17,000.

I was hoping that you would have chimed in on this rivets. I'm completely lost on this issue.
I find it really odd that one day outta the blue this would happen.

Easiest way to check is to grab hold of a blade, and see if it moves up and down. On some mowers with really tight deck belts, may have to take the belt off, to make it easier to move blades.

You didn't hit anything did you. If spindle bearings are fine, and you didn't hit anything, then my next thought would be something has sprung the deck causing a height difference.
