BX2750 Snowblower Operational Question

[Junkman]

I have found the BX2750 snowblower to be a great snow clearing machine, however if I put some down pressure on the blower, it makes a scrapping noise. I have observed that all of the paint in the back of the blower where the second stage impeller is located is completely worn away. My question "is this a normal condition with others that have the same snowblower?". My second question is "does your BX2750 snowblower make scraping sounds if you apply down pressure while pushing snow?". Last but not quite as important, "does your chute become difficult to turn at times while blowing snow?". Thanks...... the Original Junk....... /forums/images/graemlins/grin.gif

I have only used the blower for 3 hours, no scrapping noise that I can hear over the noise of the BX and in a cab.

Yes mine was worn too, I also noticed not much clearance between the fan and the housing. On my Puma the gap was at least the thickness of a quarter plus.

Nope, and I was turning it a lot between each pass.

Junkman, on mine (MF, but pretty similar I suspect), I can't say I hear a scraping sound. But, in heavier snow if I'm working it too fast, I definately hear a change in the blower. You mentioned "pushing snow". I don't push with my blower; I slow down so the blower can do it's thing. If you are really pushing that might be where the scraping sound is coming from?

Paint...well I lost most of mine last year. It doesn't seem to affect the performance of the blower at all. Hard to keep paint on those impellers with my partially graveled driveway... .

The exhaust on the GC2300 actually warms the chute which seems to do two things. On one hand it keeps it relatively easy to turn because ice isn't forming around the base. (Shortly after shut down, it freezes so I have to clean it off before I put the tractor away or I won't be able to turn it next time.) On the other hand, unless I have the deflector fully extended, snow exits at the "pivot" as it's being blown, and in real cold weather starts to build up on the outside of the chute, sometimes making it a bit harder to turn.

If you think a quarter thickness clearance is a lot, don't look at an older Lucknow blower then! /forums/images/graemlins/tongue.gif
All the ones I looked at had 1/4 to 1/2 " clearance between impeller tip and housing. They seemed to work fine. I can throw snow 30' with mine if I spin it up fast enough. Far enough for what I need, anyway. /forums/images/graemlins/grin.gif

When I say "pushing snow", I mean that I have removed most of the snow first with the snow plow. I then use the blower to clean up in front of the garages and try to get the last of it off the asphalt. I think that the steel housing is flexing a little and the rear impeller is scrapping the sheet metal. When I come into a snow bank, I let the blower handle the snow and only advance the tractor at a rate of speed that it doesn't bog down the blower or the engine. I usually operate the engine at full throttle when blowing snow, unless there are things such as cars around that might be damaged by the velocity of the flying snow. I remember many years ago when I got my first snow blower, I took out 2 windows when the blower threw a few "pebbles" at the car. I have learned that it is important to keep everything away from the exiting chute.

I've not noticed any scrapeing noise with down pressure on the 2750 other than the normal slideing on the ground. I have worn off a cutting edge already pushing on it hard. The paint is worn off ours too, was with in the first 2 hrs of operation. Paint is gone from the inside of the shoot and nearly gone from the whear side of the augers in about 13 hrs of opeation. The snow I move with it is not clean, stuff that has been plowed off the street or dirty from snow drifted in from the feild. Does it look like the augers have been rubbing on any thing? The old ariens auger would rub the sides occasionaly under alot of pressure making more of a squeeking noise tho. The spout turns fairly easy but does turn a little harder under load but not much. It's more noticable if a little gravel or sand gets in it. Good luck

Is it worth painting these wear areas in the spring before I put the blower away till fall? Or is it a waist of effort?

 

[PineRidge]

Junk we keep ours tilted to the heel so that we don't pick up and throw nearly as much gravel as if it were sitting flat. Once we get a good hard packed base then we level the blower from front to back and let er fly.

We always wait until the summer months and then drag the blower out onto the concrete pad so the better half can touch up all the paint rubbed off from the winters use. When it's real hot I give her a cold drink while she's working. /forums/images/graemlins/wink.gif If she quits I take it back. /forums/images/graemlins/blush.gif

I paint mine just to keep the rust away. I could probably just coat the area with a little oil and accomplish the same thing. Doing nothing would probably also be acceptable since any rust will disappear after the first use.

Hey Junkman,

I have the shoes adjusted so that the scraper rides just a whisker above the concrete. When I apply down pressure, it changes the pitch of the blower, and causes the blade to scrape. Yes, this is often an audible procedure.

I also notice lots of missing paint in the fan tunnel. Much more so since yesterday when I hit a pile of 2" landscaping stones bordering my neighbor’s driveway. It sounded like a tommy gun for about two seconds, till the shear bolt selflessly sacrificed itself.

My chute has always been easy to operate. However, I can see how it could easily bind if things aren’t just right. It was a constant battle to keep my (30 year old) Ariens blower chute turning, and it was a very similar set up to the 2750.

If you try to turn the chute while underway and blowing snow, it will definitely turn hard and it may not be possible to turn it if the snow is too dense. This is normal. If you try to turn it very slowly, this helps.
With the way the snow is apt to blow around, I have taken to stopping momentarily and as the volume of snow coming from the chute stops, I turn it. This way, you also avoid the faceful that the wind catches.
Of course, those of you with a cab are going 'what's he talking about'??

So Mike what is Rose's handle on this sight? She must have one so that she can defend herself does she not? /forums/images/graemlins/confused.gif /forums/images/graemlins/grin.gif

Junkman I may be wrong but I get the feeling your concerned about flex of the whole unit and that it is causing the noise and maybe causing things to be miss aliened I.E. hard to turn shoot. I guess you would have to try experimenting with that. Is the shoot always hard to turn with down pressure.? Maybe a straight edge could tell you something? Any way I may be way off here just some thoughts.

 

[boustany]

I don't have the same blower, but yes and yes.

My blower subframe pushes down hard enough to lift the tractor up, so I can scalp or scrape easily (unless I 'float', which can be tricky).

The impeller on any blower I've had loses paint quickly. I figure its a combination of the odd bit of gravel and the inherent abrasiveness of snow.

 

[Av8r3400]

I allways give my snowblower a good bath of WD-40 in the spring for rust prevention. The paint will come off again the first time you use it. /forums/images/graemlins/grin.gif
