Check out this video and pay attention to the blower and see if you can find anything wrong.

Looks like it's running backwards.

It almost looked like the impeller was turning backwards.

It is running backwards. The end of the video shows it running slowly. Try this trick to know why. Throw a tennis ball normally, like a baseball pitch. Then do with it resting in your palm only.

 

My goodness, hydraulic flow on a skidsteer is reversible, maybe his hydraulic pto is only built to run one way.

I think the impeller is turning the direction it should for the orientation of the chute.

 

The auger looks to be pulling the snow into the impeller.

I agree it's running backward try switching the hoses around to see if that helps it out any

When a snow blower is running properly ( two stage) it doesn't throw snow back out the front. At least the two I have had didn't. My single stage does but I have seen may SS do this. I agree that the secondary auger appears to be turning incorrectly. It should be turning clockwise instead of CCW.   Not sure but I think as Cat and others have said, might try reversing the lines to see if that helps.  JMUE2CW.                                                                                        Roger

If you changed direction,you would also change direction of the auger and it would be pushing show instead of pulling it in like it appears to be doing.

 

I think the paddles are bent in the wrong direction on the impeller.

 

Tractorgarden has a blower that has the paddles the wrong way and he will likely chime in about his blower.

I would guess the roller chain that connects the first and second stage together (on the left side of the blower) is routed incorrectly, allowing it to turn the correct direction.

 

The snowblower in the video is made for a compact tractor. It is attached to a homemade A-frame, welded to a skidsteer mounting plate. It has a hydraulic motor 540 pto. In the video, when he shows the pto running, you can see it is running CCW. That's the wrong way, most SCUTs and CUTs run CW rotation.

It'd be hard to change the direction on one auger with the chain drive.  It would almost have to have the gears backwards in a 90 degree gearbox to make them work opposite - much like turning the ring gear over to the other side in a differential to reverse direction of travel. 

 

Didja notice the angle of the universal joint?   Wholly crap thats a bad design!!!!!!!  :(

I agree, it does look like it turning backwards, I wonder if the impeller was assembled backwards though ? Looks lke it needs be taken off the shaft and turned180 degrees !

On my second look , looks like it can only go one way though ! Could have been welded wrong from factory ....

I have a feeling it is turning the correct direction, I think its an optical illusion like when you look at a spoked wheel and it looks like its turning backwards. If the auger is turning the correct direction I dont see how the impeller could be turning backwards. I think the snow getting thrown forward is from the plate he welded on the auger.

Im thinking optical illusion because the secondary impeller seems to be turning too slow which is the case when that happens

The old farm boy in me says the blades on the blower need to ditch the  " L " fold over in favor of slightly curved blades . Upon ejection of snow they pressurize with air an snow has a backpressure at that point in time . A little more rpm on the blower would help .
