Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I purchased this machine new about fivve years ago. Hs only been used four times. Last week i started blowing snow. Engine runs great, chute works fine. Reached the end of the driveway and it stopped moving. Let off the pwoer leer to turn it and would notb move. Had to manhandle it back to garage and switch from my 1500 piece of metal to a shovel. Any ideas? Did make ny unusual sounds. Just woun't move. Is there a cable I'm missing, perhapsw. Any assistance is greatly appreciated as we are expectig a rather large amount of snow in the nexxt ew days. Thanks in advnce.
