I just got a used MTD riding lawn mower model 13A4065-129. I replaced all of the belts and sharpen the one blade. When I go to cut grass, everything is turning and working but not cutting. It is sucking in leaves and sticks but just not cutting the way it should. What could be the problem??

Don't get mad at me , but make sure the blade is on right.

Did you inspect the blades to make sure they were put on in the proper direction and now up side down ?

It is turning clockwise with the blade going forward. That should be correct, right?

It should be stamped on the blade. It shows the direction or says "grass" so you know how to install it.

Yes but I meant did you put the fin up and the sharp side down

I'll look tomorrow and check. Could have done that. Thanks
