Abstract: A motorized ice breaking apparatus has a housing with a power source connected thereto. A drive train is operatively connected to the power source. The drive train includes a drive shaft with a crank. A blade is disposed on a bottom side of the housing and extends laterally from a first side to a second side of the housing. A connecting rod is pivotally connected to the blade and pivotally connected to the drive shaft's crank. A pair of guide channels is connected to the bottom of the housing, one guide channel being proximate each lateral side. Ends of the blade are slidingly engaged in corresponding ones of the guide channels. The power source rotates the drive shaft and imparts a reciprocating motion to the connecting rod through the crank. The reciprocating motion of the connecting rod reciprocates the blade in a substantially vertical motion.
