maybe these pictures will help...not sure about how yours is mounted to the frame. Take the battery out if its under the seat and take a look see. First thing take the 2 belts off. since you are replacing the pulley go back with new belts and check the idler pulley also. After removing the belts just unbolt from frame to remove
Ok spin the variable speed pulley and make sure the bearings are good and check the long belt idler. Install new OEM beltsOk I got the 2 belts off of the variable speed pulley...the pulley moves freely up and down, so apparently that pulley is not the problem and no need to remove, correct?
So why is the mower not moving in 1st-4th speeds, only 5th and 6th speeds?
