Traction lock problem

I have a sears craftsman snowblower model 247.888530. The auger and traction levers should be depressed simultaneously and I should be able to release the auger lever and the auger should keep running so I am able to use chute control. However, the auger stops when when I let go of auger lever. Where could the problem be?

Try some cheap stuff first. Try engaging the auger, then engaging the drive, then releasing either one at a time from starting with the auger engagement, instead of doing it simultaneously. A simple look up under the dash to see what the horizontal rod connected to each lever handle is doing. I have a Craftsman in my garage right now, but it is a 536 prefix (Murray design) where your 247 prefix is an MTD design, and they are very different when looking at parts schematics. I agree with stormr where you should be looking IF it's not a simple out of sequence user error. Other thing to consider is the cable tensions (or rod adjustment of each control lever). If one or both are sloppy, there may not be enough counter resistance tension to activate the interlock (like the interlock doesn't feel anything to lock).
On your IPL it looks as though there is a cam with a notch that accomplishes the "lock". Often times these are nylon and may have worn out the notch (kind of like a worn sear on a trigger if you have any firearms experience). The edge it catches on is no longer an edge, but a rounded off bump. Sometimes there is a spring that swings that interlock that may have lost a mount bend or the hole the spring mounting bend goes to has egged or cracked through.

Dave, I played around with my Craftsman here and it's very mechanical, as in there's no way you can miss it. I went back through my notes on neighbor, friends machines and saw the cable slack could be your problem. I never take pics when I do stuff because my hands are too dirty and I dropped a good cam at a loss once trying to do it. Just take a look at your cables and see if they're floppy. One other note I made was handle grip pad slid up the handlebar and caused the "flapper handle" to not be able to complete full travel. Just FYI.

Well I took a look at it today. It seems that the pawls were not lined up. It was an easy fix. I removed the traction handle and gave the handle rod half of a turn and put the handle back on. Works beautiful now! Thanks again for your help.
