The pedal for the swing boom control won't press either right or left. It was very tight a month or so ago, but now won't depress at all. Anyone have a clue whats going on. Nothing about adjustment in the service manual.
When I bought a '05 305 cr around 2010 the swing peddle also quit, I took the peddle its self apart and found out the little knobbs/balls that push down were seized up probably from lack of use, I not familiar with your machine layout but I think I had to take the shroud off under the cab and take apart the valve from there. Be careful because there are small washers and parts that can fall out and its easy to loose them with the oil that will flow out. You may just want to try lubing it with WD40 or Kroil from the outside first.
