is this cable for engine brake or power drive? Or can it be used for both?? So i would need to buy 2 since i'm replacing both?

Is this cable for engine brake or for the power drive? or can it work for both? so I would need to buy 2 if I'm replacing both (drive and brake)?

It works some time and all the time something fails.
1. Engine separated from the deck. Two bolts M8x60 were lost.
2. Bearing seat broken, both belts were unusable.
3. Cable to driving assembly broken at sharp bent at rear cover because of wear at bent.
Mower DB2194SH purchased on September 10,2022. What about warranty?
Particularly about cable 303200148, wearied and broken at sharp bend at rear cover. At web page it said delivery FREE and FAST. However, at payment page $11.98 was charged. What about this controversy?
