    I have a 05 super z 27 horse 60 inch. I put some high lift blades on it and when I mow the mower is bogging down. and losing a lot of power. How do you raise the rpm's on the mower. with a 27 horse it shouldn't be bogging down at all should it?

    RPM adjustment is done with a cable adjustment and possible governor adjustment.
    If this is something you have never done before I would let a dealer do it.
    If you don't have means of reading the RPM's you could go to high and cause engine damage or pre mature engine failure.

    Depends on which " high" lift blades you got. The 27 HP is not enough for the 1.5" high lift .

    Measure the higth of the sail. If its 1.5" high, it will put extra load on your 27HP. I have seen this blade advertized as high lift by some companys and " super high lift" by others.

    I know from your post that you are running the same blades as I am. I have the same mower. I have found that I needed to raise the deck about 1/2" higher than I normally would cut and that eliminated most of the bogging down. I think the slight bogging that occurs is minor compared to how well the blades cut. Perhaps tweaking the RPMs a bit may be helpful overall though. Let us know if you do it and how it works for you,
