    I have a ferris 3100 that is not cutting very well, I put new blades on clean out deck but it seems like the grass is not getting cut not leaving a clean cut, I thought about trying to adjust the clutch but could not find the adjustment like on my other mower, could it be the clutch is going?

    Did you take the deck out of its transport position?

    I know, stupid question.

    Just a suggestion. I don't know much about ferris..
    Could be a belt slipping.
    Is the deck one or two belts.
    Or it could be a bad spindle causing to much drag on the belt which will cause the belt to slip.
    Or it could be the clutch.
    For me I would start with spinning the blades by hand one at a time and see if the belt slips on the pulley or the clutch is slipping.
    That should get you somewhere.

    I just checked by turning key to power but not running and turned on pto and I could turn the belt and feel the clutch turn so it must be the clutch going out I did check my other mower and could not spin
