Long time lurker first post....

Does anyone have any info on the B2771 51" snow blower? I'm looking at one for sale locally that mentions it was mounted on a the front of a B series. I was wondering if I could adapt it to put on a old F2100 front mount? What way does the impeller rotate?

The price is right and I'd love to put a blower on my F2100 (CCW front PTO, 1100 or 2500rpm). I can fab a mount for the F series front arms, but I'm wondering if the PTO input will be appropriate.

Any advice is appreciated.

Ok the prefix letter tells what the fitment is 90% of the time. So in this case B fits a B series and I think 2710/2910.

Some of the BX series blowers can go on the non deluxe B series!

According to the sellers ad, it was mounted on a B7510, from what I can gather by Googling, the mid-PTO runs CCW at 2500rpm?

If so, this would suggest I could adapt this blower by fabbing a mount and figuring out a PTO shaft....

Where in eastern Ontario are you? I am just east of Cornwall.
Before making a deal do some searching this forum for shear bolt failures on front mounted blowers. For some owners it has become a nightmare and best you are fully informed going in.

There is likely a chain sprocket assembly on the back of the blower you are looking at to lower the speed of the blower fan to a nominal 540 rpm from the mid pto speed of nominal 2,500 rpm.

If the blower has the gearbox between the two halves of the auger realize you are buying a glorified walk behind blower and not a down scaled design used from 300 hp tractor down to 16 HP,.

If you will pm me your email to

I will forward my lengthy email to Kubota today which contains photos of problem areas and history of the problem. In your email mention what I promised to send you as I am involved with a number of threads.

I do not own a small blower, mine is much larger but I have been trying to help owners across Canada and USa and even to Alaska, solve frequent and repetitive shear bolt failures.

Dave Eng, what is your continued beef with Kubota/Rad snowblowers? You keep going from thread to thread telling people not to buy these snowblowers, but have said you have never used or owned one. Granted, there is some parts that could be designed differently, but it kind of sounds like you have a financial interest in a different brand. Shear bolts are meant to break when something gets caught in them. Chain drive has its advantages until the chain and wearing sprockets start wearing, then it can be a nightmare keeping the chain from breaking and on the sprockets.

I'm South of Ottawa.

I realise how front mount blowers are built and have quite a few hours behind them. A lot of that time was commercial work behind a F2560 front mount back in my younger days. I rarely had any issues and in fact, it's one of the reasons I'd like to find a blower for my F-series. These are the only blowers that work with my type of tractor.

Do you have a remote on your F series mower? It looks like a hydraulic chute rotator is on it.

Pat
No, I don't. The factory remote is super expensive, but I have since work arounds with creative plumbing.

Unless I had another implement that needed hydraulics (I don't), I would likely convert the blower to electric rotation.

I am 70 and don't have a financial interest in anything. What might yours be?

Because of my background in the technical world, friends and neighbors in the ag community where my farm is located started to turn to me with problems.
A telhandler whose brakes would glow red when driven on the road, a milking machine for a small local farmer which was buzzing when it should have been humming and did not milk the cows. Some diodes from a GM alternator and he was good to go. A multi million $ dairy barn, built on a well driller's assurance that the well he drilled produced 25 gpm. Once they moved hundreds of cows in they ran out of water. They needed a short term i.e. immediate fix and then a long term one. You cannot just leave dairy cows and say see you on Monday because no one will come on the weekend.

A dealer of Belarus tractors turned to me when his mechanics could not understand the Russian electrical systems. An owner of a Zetor tractor which was not charging and no one knew how to fix it. I did and for free.

I am free to all and there is no waiting. What I do and what you are objecting to, is to read voraciously of other peoples problems with machinery. I remember their stories and when a pattern of problems emerges, I get involved. First step is to caution potential buyers of that type of equipment to avoid what other owners of said equipment are experiencing. That is a club they do not need to join at least until a cause and solution is found.

Between this forum and the other large forum, people I never met nor heard of are coming seeking help that in this case is shear bolt failures, their dealers are not resolving. If their dealers resolved their problem, we would not see them on the forums. These are people who, when you look at their posting history have had little to no previous involvement. I do not seek them out, they come to these two forums as a last resort.

Perhaps you are a fountain of wisdom to owners with problems. I have not read your profile. If you are an expert show me and I will back off and you can tell these desperate owners of RAD blowers what to do.

Some of these owners have acquired various tidbits of information which, when assembled, start to paint a picture. RAD who has been building this style of front blower for Kubota and others, agreed to talk to an owner directly.

He learned there was an upgrade for the product he was experiencing shear bolt failures on that involved the latest style of shear bolt assembly, BUT, it needed an upgraded gear box as well. This manufacturer's upgraded product parts could be acquired through Kubota but the cost was very high.

I mentioned in another post a neighbor dentist who is not restricted in what he can do by $ unlike most of the rest of us. He told his dealer fix it at all cost as he did not want any more shear bolt failures blowing snow on his paved driveway. He got what he wanted for $1,500.

I don't think people who bought a Kubota tractor because of its reputation for durability and reliability, ever thought the front mounted blower their Kubota dealer recommended and installed was going to be unreliable in the paved driveway world it was going to be asked to perform in.

I await your offer to "be the shear bolt expert," on both forums.

First some background just to provide some context to my question.
I asked the question of why a grade 8 fan shear bolt on one forum member's front blower and other members have instructions and parts from Kubota saying Grade 2.
I showed a photo of the grade 8 shear bolt in its Kubota package with the part number visible.
I asked if anyone knew a way to determine all or which blowers this Grade 8 was shown by Kubota parts to the the right part.
One member googled the part number and found it was for the fan on a B2781 /B2782 3 pt hitch blower.
I understood Wolfman's reply to be that it cannot be done using Kubota parts info.

I have looked at these two models of blowers a few days ago and posted they were made to be either front or rear mounted and the reduction chain drive could be added or removed to suit the applications.

The other models of front blowers, I don't recall seeing them available with either front or rear hardware.

Do you or anyone else know if their model of blower can go either way or was this a feature with a short life with Kubota sales?

In Messick's parts view for the B2781/B2782 blower there is a part called a shear plate, #70060-03402 for $29.49 in the notes column there is another number 659492 which I have no idea what it refers to.

The illustration of the shear plate is very poor but I am thinking it might be the black part in one photo near the fan hub which one dealer installed for his customer.

You mention a F2560 which you spent a lot of time on. While I can find info on this particular tractor, I cannot find a blower for it. Do you remember the model number of the blower that would have been on the F2560?

I came across a blower which you might wish to consider buying. It is an older Kubota/McKee unit which was a front mount and has been converted to a rear mount. What it would be for you is a very tough foundation to make fit your tractor.
I will send you a pm with the link.

Longknife, Dave_eng,
The blowers that fit and work on the F2100 are:
F2450 CB
F2450 CB-1
F5210 A
F5210 B
F5220 A
F5220 B
SB45-F
SB52-F-A
SB52-F-J

Now will a B2771 work on it?
It might for a while, but there is a huge difference in the design of an F series snowblower and an B series snowblower!
The B series blowers that a lot of people are having issues with, has a small gear case mounted in front of the blower that is prone to failure, along with the annoying and costly shear bolt issue.
You would be far better off getting a normal heavier three point mounted unit and converting it to work for you.

Here is a picture of the used blower I am suggesting to Longknife;









Certainly it could be bought for half the asking price and is a proven design for more than 30+ years. You would have a blower which was made to be either front or rear mounted on the B7100 type of tractor.

"Eric the Oracle" has manuals showing the parts for it.

That is the same style of design that is the suggested units for the F2100. ;)
