I have had the 421 for 12 years. It’s been great. Easy to maneuver, light, takes less storage space. Pulled it out of the garage in November this year and it started on the third pull. Has been great for almost every situation. A lot of heavy, wet snow can be a bit of a challenge but just need to blow a few times during storm before it piles up too high. It has outperformed my neighbors who own larger machines with a thrower auger.

Highly recommend!!
