Can I Clog My Toro Snowblower With a Heavy Slush

I try to clog my Toro 928 with a heavy slushy watery mix. I try to see if the toro would pick up less than a inch of snow / slush. I did clog it once but I used it for 2 hours in the worst conditions. The biggest problem is the slush built up so you can't turn the chute.
