I was reading how to check blade height, according to manual.

It states to place deck in center position and measure the front

and rear of the blade. In that middle position I can't get my arm

under or see even the blade.

I was wondering if anyone knows what the max blade height

should be? I was hoping between 3-3 1/2 in, but I don't know

how to get it higher even on the last notch.

Thanks in advance.
