BX2750 snowblower

[huckflynn]

Just to clarify, I will probably never rotate the chute around 360 degrees, but I wanted the notches there, so if I went past where the previous stop would have been, I wouldn't tear the worm gear out. I figured that I would be rotating the chute some day and get distracted just long enough to hit the stop and cause big damage, so I went ahead and notched the base.

Exactly. I too am a firm believer in Murphy's Law. I almost rotated the chute too far this morning as I handled the snow at the end of the driveway. I always turn the chute as far as I can to blow the snow back toward the lawn instead of into the road. I don't want to take a chance on blowing that worm gear.

Have a happy Thanksgiving. And thanks again for all the assistance.

Dyer,

How powerful is that motor?

I see this question was discussed before I read all 12 pages (What happens if you look the other way and neglect to stop the rotation? Besides a face full of snow, are you not worried about twisting off the chute?)

Is there such a thing as a low power hydraulic motor with rotation "STOP" screws?


Nice setup.

I've re-welded at least two Kubota snow thrower worm drive screws in the last year. Notches all the way around are a good idea.
My first day using the machine this year I caught myself almost over rotating at least two or three times. I gotta cut some notches.

Thanks! I had fun doing the project. I've included the specs for the motor below (copied from Surplus Center site.) They make relief mechanisms for purposes of saving the worm gears, but as Dataway said, it was just easier to cut the grooves and not worry about hitting stops. John

Huck,

I probably mentioned that I cut notches in the chute base all the way around, so I can turn the chute through 360 degrees. I will never turn the chute all the way through 360 degrees, but figured if I hadn't cut the slots all the way around, I would eventually hit the stop and tear the worm out...Murphy's law and all. I read other threads where guys have ripped the worm gear apart doing that and the motor never hesitated, so I thought notching the base was the quickest and easiest answer. If I had it to do over again, I'd have the machine shop do the notching....mine works fine, but I wouldn't enter it in any beauty contest.

Dyer,

How did you cut the notches in the chute base??? I have the electric motor set up each time I go too far I blow the fuse, a pain to have to pull the fuse and replace each time I have done it. I do not have access to a machine shop, so it is up to me to make the notches...suggestions??

I cut mine with a 4 1/2 inch grinder and cutting wheel and smoothed out the troughs with a Dremel tool and sanding wheel. It was pretty awful looking! Then I figured out that if I drilled a hole where the deepest part of the groove trough should be and then use the cutting wheel to make my angle cuts into the drilled hole, it came out much cleaner. If I had it to do again, I'd take the chute off and take it to a machine shop to have it done. Mine works just fine and serves the purpose, but it looks pretty amateurish. People look at it and never notice, but I do....you know how that goes! John

Hi Guys - just been pummelled with snow up here ( blown 12 times to date - close to 4 feet total) and have not moved forward with my upgrade yet... still doing the manual crank. Congrats Huck on that install it looks great! I am really jealous.
I picked up my hoses today - Hoses were only 10 bucks each but the plumbing fittings really add up. I added the 90's at each end.
Just need to built my mount now but at this rate it is not going to happen until next summer. I think I will now wait for a shop to do it after seeing yours Huck. LOL

We've been hit a few times. Not a lot of accumulation -- just enough to give me a little tractor time.

I opted not to go for the BSPP elbows in that they cost $25 apiece at Discount Hydraulic. Instead I used couplers and 12" hose extensions to give me a little more play in my lines. I had the guys at my son's shop grind the chute so it could rotate 360 degrees. It looked perfect. I was all set. I turned on the tractor and tried the chute rotation. Bang! Something hung up. It broke the worm gear and bent some teeth on the chute (powerful little motor). So I brought the blower back to them to see what they could do. In the meantime, I priced a new chute and worm gear just in case ($125), I'm sure the guys at my son's shop were thinking "how did we ever get ourselves into this?" Anyway, they welded the worm gear and pounded the chute back into shape.

Everything works fine now.

I can really get some work done in a hurry with that chute rotation but I have found myself working a little too fast on a couple of occasions -- looking off in some direction while turning the tractor and rotating the chute. I've caught myself about to get a face full of snow on a couple of occasions. I can almost hear Mr Murphy chuckling "Not yet ... but soon!!!"

By the way, the snowblower worked great during our recent ice storm. I managed to keep my driveway clear while everything else was getting a coating of ice. On Friday night, the storm subsided and the sky cleared revealing a beautiful full moon lighting up the ice covered landscape. I took a couple of photos. Merry Christmas!

Back in 2005 a guy named Junkman also made the same type of hydraulic turning device for his BX2750.. I remember reading about it after reading this thread. Here is a link to this old post.
