Query: Excellent when working

I would give this machine a 5 star rating with one exception, and that is the electronic chute control. During the first use of my second snow season, the electronic chute quit turning. With a friend (former sears tech.) we took the motor apart and found excessive carbon buildup. I am now having to remove the motor and clean the brushes each time I need to use the machine. Replacement motor will run ~ $180 plus shipping currently. Wish there was a manual chute kit available. Other than that, it starts first pull every time. Great for tight spaces - able to do outdoor wheelchair ramps with 180* turn in the middle because of the steering. Great handwarmers help on long projects as well. Overall, would recommend to everyone.
