Is there a way to put a stop on the bx2750 snowblower quick hitch to keep the pto joint from striking the lower part of the frame. Seeems like kubota didnt think this thru. They say dont raise blower with pto running. I think if there was same kind of stop so you cant lift it too high it would be ok. I could see where you could notch out the lower frame burt this is under warrantee and I dont want to mess it up. Maybe some thing on the cyclinder

Put a upper limit stop on your lift depth control lever. If you don't have one. it would be easy to fab one. Ken Sweet

I dont understand what you mean? this is the hyd up/down for the loader
that works the lift cyl on the hitch

Yea, I thought you were on the 3 point. Can you put segment control stops on the cylinder shaft to limit cyl travel? Ken Sweet

The issue with the front mounts is the P.T.O., yoke smacking the hitch at the great raised angle when blower is raised as the clearance become much closer with the snow blowers underframe mount.

The only way to guarantee it will not happen is to install a stop tube in cylinder that does double duty for the belly mower BUT you will not be able to pin the mower up if desired.


The fastest way to solve the issue is this way with the blower warm and dry if possible using a white paint pen with warm paint or a spray can of white Rustoleum spray paint;


With the blower running lift the blower slowly very slowly until the P.T.O.,
shaft starts banging, then-turn off the PTO for the snow blower with it elevated.


This is the upper limit where you do not even wish to reach with the snow blower at any time- YOU NEVER WANT TO BE THIS HIGH while operating the front mounted snow blower.

Using the paint pen/spray paint and paint masking tape using the tractors hood as the reference point measure 2 inches above the hood line with the corresponding point on the snowblower chute in a straight line using a yard stick or an aluminum level if you have one long enough.


This is the point where you want to start painting a ribbon of white paint across the chute to tell you you have raised it TO FAR.

Make the ribbon of paint 2 inches wide to assure you will see it when raising the blower and you will see the white paint to tell you to stop lifting while the snow blower is operating.

what would happen if i put a stroke control spacer on the rod , like they use for 3pt applications?

NO, NO, NO, NO, NO!

The snow blower would not be able to float and clear snow to pavement.:(

Paint the chute with a white ribbon as i described to warn you to stop raising it.

the cyl is mounted upside down on this mount so float will be down, the pto shaft hits when up. how will the float be affected?

Are you sure this thing is assembled properly???? Proper hitch & driveline???

If the shaft on the hitch is too far forward I could see it hitting.

Pull the thing off and check all dimensions with the manual to verify setup.

Mine does not hit the frame when raised all the way up.

If it cannot retract fully it will not work in float

I am not sure Kevin, BUT if the yokes were out of time by 90 degrees it would be banging and binding so much that even the shear pins would not break.

There are two holes for the hydraulic lift cylinder on the quick hitch. For the snowblower, you have to use the lower one. Check this first. Maybe your model is different, but that's how it is on mine so worth checking.

that would explain the issue he has for sure as the higher mounting would limit the movement and angle.

I have had my BX2750 for many years now, and the pto shaft has never hit anything be it up or down. I don't know what tractor you have the blower on, but on by BX22 and BX23 it is engineered perfectly like I would expect from Kubota. I have to agree with some others here, something is not assembled correctly. I just refuse to believe that Kubota would send something like that to market. There would be just too many issues down the road with a error like that.
One other thing, you state that is says in the manual not to raise the blower with the pto running. Or does it say not to raise the blower while blowing snow? You have to be able to raise the blower while the pto is running so you can turn sharp corners without plowing up a bunch of gravel and also while backing up you would not want to drag the blower backwards. I questioned my dealer on this very thing when I bought my big blower, and he explained it to me that they don't want you raising the blower while in the act of blowing snow. In other words, while the blower is full of snow. When you have to raise the blower, before doing so, stop forward momentum, let the blower clear itself,then raise the blower. This has always worked for me on both my front mounts without any problems for many years now. He made is sound as if Kubota's concern was not to raise the blower while full of snow. Not sure if they are concerned about the additional weight of the snow, or possible extra stress on the auger. But I assure you, to get through drifts up here (MN), it is quite often necessary to raise the blower as high as I can and cut the top of the drift off, then back up, lower the blower and get rid of the lower half. On page 21 of my owners manual under the heading, Snow Removal Methods, it even spells out this process
I'm guessing you will find some assembly issue with your blower. Good luck.
