Single-stage snow blowers come with a variety of chute types. The chute control directs which way you blow the snow.
To turn the chute without stopping, consider a model with a Quick Shoot or lever-operated chute.
If you don't plan to turn the chute much, then a manual chute may be fine.
This poses an inconvenience in comparison to operating the chute while in motion. However, it usually is the most affordable option.
Lever chutes are one step down from a Quick Shoot chute, and make operating the chute while in motion quite simple.
To operate a Quick Shoot chute, simply slide the trigger grip up and down to turn the chute from side-to-side.
