I have recently acquired a 2000 MTD Yard Machines model 13A6672G129, and I'm going through the process of tuning it up.
I'm at that point where I've successfully removed the mower deck and have turned it upside down on a workbench to remove the blades for sharpening. I am attempting to remove the blade wth the logic that this particular flex nut should be loosened by going counter to the direction that the blade turns in order to cut the grass, which cuts in a counter-clockwise direction (again with the deck upside down on a workbench). Therefore, the loosening should go in a clockwise direction.
A general rule of thumb is the retaining nut or bolt will always tighten opposite of the rotation of the object. Take your bench grinder, the right wheel is secured with a right hand thread nut, the left wheel with a left hand thread nut.
