    How do I loosen the tension on the control bar without loosening the control knob?

    In other words, I have the control knob turned all the way up for maximum tension on the belt and maximum speed but this causes the control bar to very tight to pull up on.

    Would a cable adjustment help?

    On my other toros it is much easier to pull up on the control bar yet they are still tweaked for speed.

    I had the same problem on one of my units. The problem is not the self propel cable but the carb cable. It is the one on the other side of the handle. You can check to see if it is the problem by squeezing the lever like you normally would for mowing and then you can feel the cable and see if it is unusually tight. If it is, you can move the "sheath" a little after you loosten off the nut that holds it to the handle.

    I have already tried loosening the "engine kill/start" cable but when I loosen it enough to reduce tension on the control bar there is not enough tension on the "engine kill/start" cable to pull the spring away from the ground.
    So I cannot start the mower without that tension on the start/kill cable.

    What about disconnecting that cable altogether and installing some kind of manual toggle like start/stop switch.

    Any suggestions on how to disconnect/bypass the brake cable?

    Does the Toro 21" Have a blade clutch?

    No blade clutch, no bbc, just 3 cables
    1. throttle
    2. brake/start/stop
    3. drive cable
