ust got her running sweet and laid into the driveway, and the front auger stopped turning. Then iot started working. Then it stopped again. Now sometimes it works, most times not so much.It's also making a grinding sort of sound that appears to eminate from that area. I checked the belts, they could use to be replaced but are still working. I also cannot figure outn how thet come off ,unless it requires some major disassembly. I am afraid the problem is in the mechanical drive for the auger. Does anyone hace any info or a diagram of this unit so I can attempt to fix it myself? Thank you in advance for any input.
