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

I have a 10hp 28" MTD model 660 2 stage blower w/ aTec Sno King motor. This unit has seen only two winters. The problems I'm experiencing is with the unit not throwing snow worth a dam ,until the auger and impeller has been running at least one pass up the drive (50 yards.) The motor runs strong and fine. The wheel engagement was sluggish yesterday as well. Could this be a simple case of needing to replace the belts. It would seem that once the belts warm up it works fine. Any and all comments are welcomed.
