Works like new again.
The drive cable was exactly like the old one. Installed in a few minutes and the mower works like it was when it was new.

Cable Replacement
All went smoothly..both times. I ordered the wrong part at first and got it right with the second order. The part worked perfectly and I was up and running. What I liked best was the ease of finding the picture of the parts on my older mower and the on-time shipping from the source.

Removed old pieces of the broken traction cable.
Followed the online instructions provided by ereplacement web site.
Tested cable tension a little bit and then repair completed.
Need to be willing to get your hands down into the belt area to make lower connection. Hands need to be able to access this area.
Overall, great response from ereplacement for shipping and never missed a lawn cut.

I followed the steps a previous user had posted on replacing the Traction Cable; replacing the Cable Guide required more research. Borrowing from the previous user, here are the steps I took for replacing the two parts:
1. Remove trim bag or mulching plug.
2. Remove two screws that hold plastic cover on rear of mower platform.
3. Loosen nut that holds the traction cable clamp near the mower handle.
4. (First, I took a picture so I would recall the direction of the spring hook in the lever mechanism of the drive belt.) Unhook the spring at the end of the cable from the lever mechanism of the drive belt.
5. The Traction Cable is locked-in-place by threading through a guide hole; I used needle-nose pliers to squeeze the tabs in, in order to slide the cable back out of that hole. This looks to be a standard feature to lock-in-place when a cable is threaded through a hole, but this was the first time I had worked on a cable; knowing how to disengage this lock in order to pull the cable back through the hole is very important.
6. I now paused in the Traction Cable removal process, in order to begin the Cable Guide replacement process. I disengaged the S-link at the engine end of the Brake Cable.
7. In order to pull the Brake Cable through the hole in the bracket, I used needle-nose pliers to squeeze the tabs in.
8. I slid the broken Cable Guide off of the two cables.
9. I snapped the post of the new Cable Guide into place on the Lower Tube.
10. I threaded the Brake Cable through the Cable Guide, then through the hole where the tabs will lock, and reattached the S-link.
11. Remove old traction cable.
12. The new Traction Cable needs the spring attached to the drive-belt lever, and the cable lock (with the tabs) needs to be pulled through that hole. (I don't remember which one I did first, or if it matters.)
13. Route new cable through the Cable Guide, by the same path the old one was routed.
14. Attach the cable to the traction lever near the mower handle.
15. Tighten the cable clamp near the mower handle.
Note: Test the engagement of the drive belt and adjust the cable position under the clamp so the the belt does not engage when relaxed and engages well when depressed.
16. Replace the plastic cover and screws.
17. Replace the mulch plug or trim bag.
1. Remove trim bag or mulching plug.
2. Remove two screws that hold plastic cover on rear of mower platform.
