Got someone coming this afternoon to pick up the riding mower to fix issues. After the last mow of the year last summer, the right side blade got very "wobbly", and could not be tightened. Mower is four years old, so about time to start having issues I guess. Yard is about ready to mow again, so need to get the thing up and running well. I'm not "mechanically inclined", so if I tried to fix it myself, it would most likely become in worse shape.
