Drive belt wear
Any ideas what could be causing the drive belt wear seen in following pictures?

Sorry some pics blurry. I also pulled belt off to side of pulley so you could see some of the wear.
I did have some slow speed engagement problems earlier that I was able to address by adjusting the drive control rod. It seems there was too much slack. I haven't had any engagement issues since and I suppose this wear could've occurred before the adjustment of drive control rod.
One theory I have is that clearance of the traction drive pulley in regards to the friction drive might be too far apart and causing this wear. If drive pulley is pulled closer to wheel the belt wear may be mitigated on that one side of belt. Visually looking down at drive pulley I see belt rides that one side of pulley in the drive disengaged mode. In drive engaged mode it appears they line up correctly. This blower doesn't have any belt adjustments. They tell you to just replace the belts when they are worn or broken.
Service manual says the following on clearance:
"the disengaged position adjust the clearance between the Rubber Wheel Ring and the Drive Plate Assembly to .125"-.140". "
This is adjusted from from where the control rod attaches to lower left side of rear frame body by a spring. There is a nut that can be adjusted on the clutch rod.
I usually only plow in lowest gear and don't really push it. Auger belt is perfect. I intend to monitor the wear to see if it gets worse or stays in holding patter. I do have spare belts. It seems only about half of the belt has this wear so at some point there was some slipping that occurred on about half of it. The other half on that side is in good condition.
Drive engagement works perfect too.
Thoughts? Let me know if I need to clarify anything.
Thanks!
