McCulloch MC621 Snow Blower

The McCulloch MC621 Snow Blower is the introductory snowblower model from McCulloch. Unlike most snow blowers these days the MC621 is actually a single stage machine. This means that it does have an auger but it lacks an impeller. This means that when compared to larger dual stage snowblowers, it can’t process as much snow. This McCulloch snow blower uses a 4 stroke engine designed and built by LCT that has an output of 9 ft-lbs of torque. This engine has a displacement of 0.21 liters. Also unlike a lot of other snowblowers, the MC261 only has one choice of starting mechanism. This is it’s recoil, pull cord that requires a bit of effort to get it going, and more so if it is very cold when you are starting it.

The McCulloch MC621 snowblower does not have a gear system. In fact the wheels on this snow thrower provide it with no forward momentum at all. Instead it uses it’s rubber auger to pull it forward. The rubber auger is slightly over-sized, which means that it touches the ground as it turns. Each time it touches the ground, it gives the MC621 single stage snow blower a small pull forward. This adds up to provide consistent forward motion provided that the auger maintains consistent contact with the ground.

The auger on the McCulloch MC621 snow blower has a diameter of 0.2 m (8 inches) and as mentioned before is constructed from rubber, not steel. After the snow has been chopped up, it then gets thrown out through the plastic chute and away from the clearing area. The chute can rotate through 180 degrees. Even though this is a one stage snow blower, it is still capable of throwing snow a distance of up to 13.7 m (45 feet) from the chute.

    Bad. Don’t like it. You don’t know if it will start or not. It is an electric start but it you can’t count on it starting.

    Year of Manufacture: 2015
    Cons: Used it one season from January 4, 2015 through March 2015.
    Cleaned it and put it away in storage until Nov. 2015. Couldn’t get it started. The spark plug was wet. Dried the spark plug. Put it back in, it started. Used it over the weekend of January 9, 10 2016. Tried to start it on January 12, 2016. It won’t start. I should have gone with my gut feeling and purchased a Toro. Had them in the past and loved them. The scraper bar is not designed very well. It gets stuck on bare cement, a little piece of ice, or a pile of frozen snow. You have to push down the handle bar of the snow thrower to left up the front and re-position it.
    Not a good snow thrower at all. The chute freezes up no matter how well you clean the snow and ice around it after using it. Never happened on a Toro.
    Modifications: Figure out why spark plug gets wet. Change the design of the scrapper bar. Also, figure out a way to prevent the chute from freezing up. Never happened on a Toro.

    Worst piece of equipment I have ever bought.

    Year of Manufacture: 2010
    Cons: I bought this new last fall. The 1st came damaged. I sent it back and they sent another the same model. I did not know that this one was also damaged. I started it after fueling and putting the oil. It made and awfull nose and found out the augerhousig was bent up. It tore the auger rubber up and the scraper bar is also shot. I pounded the auger housing down and it was better, but when I went to us it more snow came back from under it than out the blower shoot. I read where others have had the sme trouble with the snow coming back at their feet. I guess I should have sent it back and bought some other brand. doe not answer my emails for replacement parts. I under stant that McCulluch has made some changes for this problem. I can not get a answer from them either. Maybe they have their system overloaded with complaints on this snow thrower. All I am asking is to get parts it needd to correct this problem, Larry
