Woods SS 74 snowblower

[BBELL]

The question I have is there anybody out there, that has the same blower. Do you think the impeller is big enough to handle the volume of 6' of snow that is being pushed thru it ? To me I think it should be deeper or wider. If you feed it to much snow it will just start plowing it instead. Now don't get me wrong, I'm not piling it in so that it wouldn't be a reasonable amount. I think it should be able to handle more volume. I also think the impeller size is the same as the smaller woods out there. Maybe I'm wrong but if this is true, shouldn't the impeller size get bigger with the size of the blower?

BBELL I use a smaller Woods SB60-2 and since my purchase Woods has increased the size of some of the impeller fans per my conversation with the factory. Even with the smaller impeller I have no problem when I load up the blower. I might suggest taking it a little slower on the first pass and then overlapping in deep snow on each additional pass. HP is also a factor but I'm blowing snow with 40 HP so its unlikely that I will ever bog my engine with the 60" blower.

Hello Bruce - you are on the right track -blower output is a combination of fan diameter, depth, and speed. One machine's fan may be smaller but may run faster than another machine's. You might check to see if there is any step-up of the fan on your machine.

I've noticed my 84" New Idea blower will plow up a wave if the tractor is moving too fast. It has a 24" fan, 8" deep, running at pto speed (not stepped up).

BBELL,

I have a Woods SS60 on my B2910. Are you running at PTO rpm? That's a necessity. Snowblowers need lots of power.

If you're plowing snow, you're probably just going too fast. Is your tractor hydro or gear? Mine's hydro and it's very easy to adjust speed to changing snow depth/density conditions. In light snow I have to increase ground speed to feed enough snow into the impeller to throw it properly. When I hit heavier snow, I just slow down a bit as necessary.

Like everything else, it just takes a bit of practice. /forums/images/graemlins/smile.gif

In addition to the depth and diameter of the impeller is the "tip" speed of the impeller fan. I'm not a math wizard but one could figure out how much faster the shaft speed has to be to get the same impeller tip speed on different diameter impellers.

My Pronovost P-740 (74") blower has a impeller diameter of 26" and 12" depth. The tractor that running the blower, L4330HST, is at the lower end of recommended PTO hp. If I run my ground speed is to fast for the conditions, I can bog down the tractor to stall if I want.

In my searching for snow blowers I remember a few dealers telling me that a larger impeller spinning at speed is more overall efficient in moving snow than a smaller drum spinning faster. I'm not sure if that is true.

One thing I have noticed is that snow blowers with a smaller impeller seem to shot more of a mist or cloud of snow. The larger impellers seem to stream the snow more less misting.

I'll try and get some pictures of my blower shotting the snow.

Did you get that pronovost around here? I've been contemplating a blower for the larger storms. How is it on 180 degree turns? do you have to do alot of back and forth like plowing?

On that pronovost how do you control the side to side of the blower chute?

Where about in Northern VT, more in the NE kingom, Newport Derby area???

I got mine from Kubota dealer in Sutton.

You mean chute rotation? If so it turns way more than 180 degrees. If I turn it all the way to the right side of the tractor it will shot the snow into my side post of my ROPS if the deflector is set low.

The nice thing is once the snow is blown away its gone. The only time I have to go bach and fourth is when the snow is deeper than the blower is high.

My Pronovost Puma has a hydraulic chute rotator but it is with a hydraulic cylinder. I had to put a 1" block on the piston to shorten the amount of actual rotation. This keeps the chute from over rotating and blowing the snow at the ROPS side post.
