Having trouble deciphering the IPB's of parts for this assembly or finding the right picture. The tracor wants to go to elevated rpm's unless I put my foot down on the HST pedal to move backwards or just hold it down slightly in that position. Go to move forward and the rpm's go up and stay elevated regardless of throttle lever position that is by the steering wheel. They only come back down when the HST Drive Pedal is pushed down in the reverse direction.
The cable, hooked to the front of the HST Drive Pedal, has had the outer sheath come loose and manipulating the cable there effects the engine speed. Hopefully I am making sense. I know this post is getting long.
What is the name of this cable and where is it in the parts breakdowns?
Thanks for any helpful replies or other suggestions as to the cause of the elevated rpm's.

Actually, #90 is the cable from the HST pedal to the throttle position sensor.

It is very hard to locate this cable.
The give-away is the position sensor sketched to the right of the cable end.
Thank you both for the replies. White Tiger is right on. Have the right cable on its way and will be back to work shortly.
The IPB's aren't especially helpful or named very well. I expected a little better from a Japanese mfg.

What is an “IPB”? Never heard that used before with tractors.
