Kubota F2450CB-1 50" 2-STAGE SNOWBLOWER Information

[KubotaBob2380]

I just signed up here, but been lurking for a few yrs. Own a BX2380 and just scored a deal on a Kubota F2450CB-1 50" 2-STAGE SNOWBLOWER. Seen it on FB Market place and drove the 50 miles up and bought it.

Looks a little large for my BX2380, but bought it any way

The guy who had it tried to adapt it to be a rear PTO mounted unit, see photo for his 3 pt mount. He got it mounted and made a drive shaft, fired it up and it spun backwards, lol, He said I'm done and put it up for sale cheap, said it was what he paid.

I was not going to say too much until I paid him and it was in the back of my RAM 2500. Then I told him Dude all you would of had to do was remove the gearbox on the rear and it would have tuned the right way and probably been pretty near what it needed for rpm. Dude shrugged.

No I do not want to mount it out back and spend all that time twisting my neck around and blowing snow while backing up.

How to mount/use it, thing is a BEAST of a snow blower. is it bigger than the little BX can handle? Well I'm going to give it a shot.

So, I need to know everything there is to know about the Kubota F2450CB-1 50" 2-STAGE SNOWBLOWER.

I can only find bits and pieces online. Messicks has a parts diagram most parts are discontinued.

I can find just a few mentions of it online.

Some questions. When was it made and what tractor was it made to fit?

Is there a manual available anywhere? Anyone have a copy?

Is there an official mount for this thing for my BX? Don't really care as I can make one if I want.

I am thinking of mounting it on the FEL since I have the quick detach version and have already made a few implements such as a show pusher blade adapted from a Polaris Quad, it works ok, it pushes snow around.

I was first thinking of putting the snow blower on the FEL then running a 2 section drive line up to it. Would dip pretty low to clear the front axle but might work.

Have Knowledge of the Kubota F2450CB-1 50" 2-STAGE SNOWBLOWER? Post it. Know where there is info online post a link.

Looks like quite a project.

I really have no experience with your model tractor, so I am having a difficult time "picturing" how a 2 piece driveshaft would work.

My initial thought was to get a small gas engine and mount it so that the engine runs the blower.

Then you could use your FEL to push it around.

Just a thought.

Here is a video explaining the Kubota K-Connect Front PTO system.

Im not buying a K-Connect Front PTO, I am possibly going to replicate it depending on what I can find for drive line parts. Might buy a drve line built for the 60" mower deck and lenthin it. Then make a mount system. I actually have one already for my 60" mower deck but I am not cutting that one up.

Then I might just buy the part that slides on the mid pto output shaft cut off the u-joint part and adapt it to a CV joint out to a front shaft then use a similer setup to get to the snow blower but with regular small car drive shaft parts. I can cut and weld the CV shaft to extend it all the way to the front carrier bearing shaft setup. To heck with $800 kubota tractor drive shafts, haha, lol.

Spicer makes a lot of this stuff in all sizes. Really the only part of this drive line that needs to be Kubota is the part that slips on the mid pto output shaft.

Well your probably in for a real work out.
That's a blower meant for an F series Tractor / Mower
They are much different than a standard tractor.
The PTO comes out the front of the unit and I do believe the reason it spins the wrong direction is that the PTO on and F unit spins the opposite of a standard PTO.
Will it work being powered off of your mid PTO, maybe you would have to check rotation.
It's also looking for ~2200 PTO speed, reduced down via the gear box to 540.
Your BX MID PTO is 2500RPM so you would have to run at a lower Engine RPM thus lowering your available HP to the implement.
This is the rub, you're already short on HP to run that blower so any more reduction is bad.

There is a Mid PTO powered hitch kit that is not the K connect, it's just a standard quick connect, you would be far better off getting that kit than trying to fab up your own.

Cool video.

I did not know that the MM pto was forward facing.

I guess you learn something new each day.

From what NWKaren( ) said, I would be sketchy on this mod.

But hey, what the Hell..........I'm a "half full" kind of guy when it comes to your money and time.


Edit: I do like your "double spacing" of sentences though........haahhah....It's much easier for us old farts to read.

I did go out and verify the rotation of the mid PTO and the snow blower. Your right the snow blower rotation is opposite of the pto. So that wont work, or will it?

How to fix or overcome this issue?

Remove the rear gear box. Without it the mid pto rotation will work. How to hook it up? Easy, small sprocket on bottom shaft I will construct and larger sprocket on the input shaft. 3.5/1 ratio or what ever is needed for the right rotation speed. Sprockets = same rotation direction so removing the gearbox and using sprockets and chain fixes the problem of wrong rotation direction.

Concerning the right pto rpm speed, I will determin what is needed and size the 2 sprockets to get the right ratio so the snow blower turns at the right rpm

I did see that my F2450CB-1 snowblower rear gearbox is the same as 7 other models of snow blower. I could not find info on my snow blower the F2450CB-1 but did find info on another of the show blowers that use the same gearbox.

What does that mean? Well, I was able to verify that other model, F5220 works on the Kubota F3680. Since the F5220 and the F2450CB-1 use the same gearbox model with 3.5/1 reduction the mid pto speed of the F5220 being 2545 rpm according to tractordata.com. So 2545/3.5 = 727 or so. [please chk my math] so if I am wrong some one correct me.

kubota-f3680 specs from tractordata.com

Kubota F3680 does have 36 hp so there is that issue. I did not see any data for the pto hp but logically it is going to be more then the BX2380 has. If I get the rpm right via the sprockets that will help.

There are similar size and larger snow blowers available for the BX2380, so if the BX2380 can run a 55" snow blower it should run this one at 50".

Actually since there are 7 models of snow blower that all use that same rear gearbox I am hoping I can sell that gearbox for a decent price.

haha, well I am old so that is why I like the double spacing. As you said a lot mor easy to read.

I think I can mod this old snow blower to work on the BX2380, we will see as I am going to press ahead with mounting it and removing the rear reduction gearbox so my mid pto rotation direction will work to run the snow blower if I use a lower shaft and set of sprockets sized to get the 3.5/1 reduction.

Then I will try and build a set of drive lines front and rear with a support bearing in the middle and make up my own dive lines. I do have some experence at that from previous work experence.

All I really need to start is the part that fits on the mid pto shaft on the tractor. From that point forward I will ether buy the spicer drive line parts I need, adapt some CV axles or have a drive line shop build what I need.

Why not just get the Quick hitch ( called a shoe QH) which already has the lift subframe and the mid PTO shafts with it?
Then all you would have to do is bolt the front QH mount on to the blower and make the front short shaft.

Because you simply can not add a simple mount without a subframe or you will damage the tractor guaranteed!

Thanks, looking into the quick hitch and how that would work.

Latest and long over due update on this project.

Well the snow has been little these last few yrs and my FEL mounted plow blade has been handling the snow easily.

That and the fact wife wanted a room addition in the basement has been keeping me busy and away from many projects that are on hold including this one.

So my plan for this snow blower now is to mount it to my FEL but not run it via a front PTO shaft.

Bought a 13hp Honda motor to run it. The only question is, can this Engine with 13 hp run it. It will certainly turn it but the test will be biting into 12" of wet snow at 2 or 3 mph. Wil it bog, or, will it throw that snow?

I can adjust pulley size on the engine to snow blower shaft as needed. If the 13hp Honda engine is not quite enough then I'll find a larger 20 plus HP engine out of a riding mower.

So when I get this going and it works or fails, I'll come back and post an update. Might be a while...

Feel free to post your thoughts.
