Remove the linkage pins where the foot pedals links connect to the valve spools. Notice that rectangular link on the bottom spool, note it has two holes in the front of it where the traverse arm from the left pedal connects to it. Note which hole your traverse arm pin is in. Otherwise, when you reassemble the machine, you'll be scratching your head which hole it was in.
Remove the bolt that connects the right foot pedal to the linkage arm. Pull the linkage arm forward toward front of machine.
Remove the center pivot retainer bolt and washer from the traverse arm from left pedal, remove the two pivot mount nuts on each side of the center pivot, pull the traverse arm free and forward.
