Blower performance

My JD 1128DDE blows much better to the right than to the left. Is it true that all blowers perform better blowing to one side?

I think that's pretty normal, all three blowers I've owned have done much the same thing. It's got to be because the impeller always spins in one direction and if the chute is facing the opposite way it impedes things.

I think so, the snow being expelled is following the left side of the impeller housing. (From the operators view) The transition into the chute is straight and fluent. When the chute is positioned to the left the snow discharge has to change direction.

You take the chute off it goes straight up in the air. so with the chute on left, right or straight ahead it will all be the same.

I disagree, i fooled around with this. I tried a machine with the chute off before installing an impeller kit. It gave a noticeable wash of snow being carried in the direction of the impeller. The impeller does not uniformly push the snow it flings it. That being said, the machine I tried this with was a super old Ariens with a very large round outlet and very short neck. Still the "blob" of snow being expelled is not uniform, it's thicker next to the housing since centrifugal force is forcing it outward. That effects the dynamics of the snow running into the chute was well.

"SR" blew his lid one time a couple of years back. and the snow was going straight up in the air. I forgot to tighten some bolts on him. yeah it will be thick coming right out from the collar area only to aspirate further on up in it travels.

Then it all has to do with the arc/curve of the chute. each 1 is different.

Incorrect, that's not how it works..
if you take the chute off, it doesn't go straight up, it will go up and to the right..because the impeller spins to the right.

yes, its true that nearly all 2-stage snowblower will throw noticably better to the right than they will to the left,
because when throwing to the right, the chute forms a natural part of the arc made by the impeller..the chute offers virtually no resistance to the snow.

but when throwing to the left, the chute forces the snow to change directions, causing much more friction, causing less distance thrown:

Funny I never noticed any difference with mine. they throw good in all directions. the only problem I have is when I am blowing it north into the oncoming wind.

Mine performs better turned in certain direction
