I have a 2012 Polaris ranger 500 midsize crew. When riding around after a few minutes I slow down to stop and the motor bogs down due to the clutch not disengaging. 1 of the 3 fingers hangs up. I have to pull the cover off and bump the finger and the clutch releases to normal position. Any idea of what may be causing this. I have looked but I can not see anything broke or loose. I'm out of ideas and after about a dozen times of this happening I'm getting frustrated.
