rectangular exit at chute is 3"x 4", clogs, going to make 6" round
I have 3 Murrays (2 Nomas, 1 Craftsman). I don't know why Murray did this, the exit from the impeller at the top of the housing is a rectangular box protecting upwards that the chute is fastened to. The rectangular box measures 3" x 4 1/4" & 5" high.
They have a high front pulling a lot of snow in, then rather than the more common 9" impeller you'd find on MTD machines, they all have a 12" impeller which means they are sucking in a lot of snow then the impeller is pushing out a lot of snow only to be restricted by a reduced opening of 3" x 4". Then it's not as if the snow goes through an opening and out again, it has to travel up this small reduced box 5 or 6 inches before it can exit at the chute. This isn't bad if the snow is dry but it stills slows me down, I have to use a slower gear, and takes me longer! Then if the snow has any moisture, even slower, and the snow comes out in rectangular bricks.
Has anyone had or have a snowblower where this exit is reduced like the Murrays?
I like these machines, especially easy to change belts, just minutes, so easy. However I'm divided, do I sell these and use the money to buy a snowblower with a round exit? I'm not snowblower poor, I do have others, Ariens ST522 5hp 22", and an 8hp Dynamark which has a round exit. Those are for sale but.......
Or do I grind the welds on the rectangular box off, remove the box, then I'd either make and weld a larger square box, or find a local fabrication shop to make me a round cylinder to weld to the housing at the impeller. I was also thinking of finding a small not busy welding shop to do the job, seeing what they want to do the job on the three snowblowers. The two larger, 9/27" Noma and the 10/29" Craftsman, I bought used as all my machines, have very little use so I know what I have. Everything starts, runs great, carbs cleaned, serviced, new belts, tires are all good of course, paint is in good shape, no rust.
