I have a 2010 x320 riding mower. Used last summer for mowing and over the winter with the snow blade with no problem. Switched back to mower deck and on first mowing this week noticed steering to the left is no longer as sharp as to the right. It looks like the wheels turning to the left do not go the last inch or so to the stop, as they do on the right. Looking underneath, I do not see any obstructions to the rods or other pivot points. Any ideas why the turning radius is less than before to the left only ?? Thx for any and all help. Rick
