3-Point Hitch BX Rear Implement Shaft Issues

[BX23D]

OK, I see the problem. I don't have that problem, and I have the exact same blower on my BX25. The reason is that I have the original stabilizers that came with the tractor back in 2008, which have a much smaller connection piece. (Just a u-shaped thing, about as thick as a pencil.) Also, I agree that maybe the end of your PTO shaft looks very bulky. Is there another one you can buy that is a little more compact at the connection end, or maybe like wawajake says, reverse it? It could even be on backwards right now!

That big lobe also holds the shear bolt, so yes you want it the other way around so that you can get to it!

I can't reverse the shaft. The other end is not a collet style coupling, but a slip on style that requires a bolt goes through it and through the shaft of the blower gearbox. I looked at the original stabilizers, and I think they'd conflict as well. While I can keep the blower lower, I just wanted to eliminate the chances of fully raising it if I'm not paying full attention and backing up while holding the raise lever. Been there, done that. I'm looking for another shaft with a more reasonable sized coupler. This one is very large.
Thanks everyone!

Just thinking aloud, I could also add a PTO shaft extension to get the coupler out from the tractor. I'd have to shorten the shaft, and then the shaft angle might be too great for the blower if raise too high anyway. I just need to get up and personal with it and see whats up.

Robert I took a closer look at mine when snowblower up ten inches and turning, and yes the plastic shield on my driveshaft rubs against the end pieces of the pinned stabilizer (my stabalizers are same as yours) But it barely touches it keeps the two little pin ends shiny . And yes my driveshaft has the lob on it for the shearpin, but that end of the driveshaft is attached at the snowblower end not the tractor end and I don't see how you will ever be able to have the lobe end at the tractor (and I still have room to remove the shearpin and replace if need be when lob is at snowblower end.) So the noise I get when snowblower too high is just the plastic driveshaft shielding. Now one other thing to maybe look at is if your Snowblower has adjustable two lower point pin location. Mine has two positions, where I could actually have the snowblower further away from my tractor by changing the bolt location on the arms so that the two side pins move 4 or 5 inches along the horizontal plane. I kept mine close in because further away would increase the weight physics on the threepoint, but it would improve the driveshaft angle by making it less. But maybe your snowblower does not have that adjustable arms. if it was me I would get a different driveshaft, your splines on the snowblower must be able to take a different kind of locked in place driveshaft , there are a variety of types and it would be weird if the spline construction of the snowblower did not have that capability.

The outer cover should not be spinning! Only the center shaft!

Wawajake, thank you for your dedication! My Kubota blower has a smooth shaft out of the blower gearbox with a 1/4" keyway and a low grade bolt, I assume for shear.
There is no way to put the splined coupler on the blower, by flipping the shaft end for end. I've been looking, and have seen other couplers that aren't near as bulky, so I am wondering if I can just change out the collet end of the coupler. I'll take a few pics of the blower gearbox shaft. I see that a spline end x smooth end shaft PTO shaft is fairly common at farm supply stores, but I would rather a shaft that is fully removable at both ends. This will require an adapter on the blower gearbox that adds a spline to the smooth input shaft of the blower gearbox. My concern is shortening the shaft end distance, creating an incorrect shaft angle when the blower is up.
Regarding the lower arm pins, I had to use the next holes "up" because my blower would not rest on the ground when fully relaxed. I cannot move the blower rearward from the tractor.

Yes, be careful Wawajake... it sounds like you don't have the anti-rotation chain on the shroud in place at the tractor end. There should be two chains, one on each shaft end.

Thanks......... those chains sometimes on sometimes not, I am never back there when it is turning until last night to see what makes noise, but I will see further about chains that go missing
