Need to removal the front axle on my GT18 and it is quite puzzling. It appears that the PTO tube is locked to the axle hub with a tensioning bolt, but once that nut is untightented I'm not getting too far. I need to removed the PTO tube from the axle hub ID before I can remove the axle from the frame. Has anyone gone through this, where some helpful hints might help me accomplish this? Hate to get out the sawzall blade or dremel cutoffs unless I am left with no other options.
