I have a Honda also and I frequently wish it could go higher, also! I don't know the answer to your question, but I am curious to see the answer because I have a lawn care business, and most of my customers only want me to mow once a week. Now it is fine, but in spring, you cut off around 4-5 inches!! I wish it went higher so I could cut it once and then do it again after lowering it, since I have to do it twice anyway since it clumps!!
