Buying Toro 1800 18-Inch 12 Amp Electric Curve Snow Thrower #38025

I used Toto 1800 for two snow days so far. The first was 6" snow and the second is 3" snow. I was very careful not to over load the machine by running it in V pattern on the driveway and each path load only 1/3 to 1/2 of the snow.

The first snow day, the driving belt slipped off on the first start after I stopped the machine to clean the snow on my cars (strang isn't it). I have to reinstall the belt. The second snow day, the machine lost its power. Upon opening the cover, I saw part of the driving belt is torned and stuck between the wheel and the casing. The timing belf is visibly torned but still functional.

I don't mind fixing it every time I use it since I am handy. But at that rate how long can it last ?
I am ordering the belts in anticipation of the day the belts break.Get more detail about Toro 1800 18-Inch 12 Amp Electric Curve Snow Thrower #38025.
