    How do you properly measure your blade height? I've got my deck pitched forward around 1/2" or less. Do I measure the front, back, or center of the blade? It cuts good now, but I want all our mowers to cut at the same height.

    I turn the end blades 90 degrees to the direction of travel, and use a "blade height measuring tool" - Get one from your dealer.

    Very true, that's the only way your going to get them to cut the same height.

    If you get too much forward pitch the center blade will cut shorter than the two side blades. 1/8 inch is plenty.

    I use a 2 1/2" deep well socket. I set on the ground in front of the blade and raise or lower the tip till the socket will pas under the socket freely. Then move the socket to the back and raise the back of the deck up 1/8" higher that the socket.The socket acts as a feeler gage.

    In fact its best to check that the front tires are inflated to the max seting. And the back 2 or 3 pounds less than max. Plus set on the mower to make sure the blade is set with you on it so the blade will not change with your added weight in the tires.

    Interesting question I never ever have been concerned about what height I am mowing......just low in spring and raise it as summer goes on. My Scag has an indicator on it that says we are mowing at 3" at this time of season and I say no freaking way it is almost scalping but it looks nice so that is where I leave it set.

    Quick, easy and cheap way to measure blade heigth. With the mower on a level surface, take whatever is handy, remove the wad of chewing gum in your mouth, stretch it out and stick it on whatever you have, slide it across until it hits the blade, remove and measure from the bottom to the indentation. No need to buy a special tool.

    The height of cut is determined by the lowest point in the circle. It would be wise to check the blade at several locations and between blades on multi blade units to ensure uniformity.
