Belly Blade

[ajhbike]

Thank you. Note that I don't have that rear lifting rod, I have a 1/2" lifting arm...and I don't have the extension bracket for the rockshaft. I will see if there is a sifting rod from the loboy and see if the lifting arm will marry up with it. Chains are okay, but as GI said above, the downward pressure would be a benefit.

Looks like I have a lift rod from the Loboy and it looks like the lifting arm is the right length too. There is just a big bolt in the center...I guess I need the lifting bracket which appears to be a piece of stout angle

Voila! Bell crank extension and lift rod

I know I'm just a newbie, but I don't think you need the "stuff" mounted in the front. Your set up should look like this:

Keep in mind there are three versions of Cub blades. Generally divided by the type of lifting strap. The original with a single lift rod attached to the blade frame, the 54 with two straps, and the 54A with the spring on the lift straps. They also vary in the style and way the brackets mount.

It looks to me like you have the 54 version. There's a good picture of the blade belly mounted in the pdf manuals section.

It also looks to me like your lifting lever for the front mount position has been modified to be a lot longer than normal. Not a problem but make sure nothing smacks into something else or binds when lifting.

In the picture you just posted above, it appears that you have lifting components from two different model blades, installed at the same time. The lifting rod (1/2" round bar) that you have connected vertically, directly to the rockshaft is correct. You also have another lifting bar, the two pieces of flat stock that go from the outside of the blade frame, Y together, then you have attached somewhere diagonally forward and up from the blade. That needs to be disconnected! You could take this set of lift bars off, and connect them directly to the rockshaft (like you have the round lift rod now) and disconnect the lift rod that you have connected vertically. This is an "either or" situation. You don't need both connected, as they do the same thing. I would guess that, as mentioned above, you have parts from two different blades, and likely have more component parts than you need, which is making it a bit confusing to figure out.

Here is a picture of the correct mounting on my 51 Cub, using a 54 blade.



You can see that there is a Rockshaft Extension, piece that goes on the rockshaft, to extend it down a few inches, making it possible to mount the lifting bars. You don't appear to have this piece, but the piece you improvised in the photo above should work.

Here is another photo on my 77 Cub, using a 54A blade. Again, the lifting components are just a little different, but same setup.

Yes, you have some mix-and-match going on with your blade parts. The double flat bars work better than the single round one. You need to make your installation look just like gitractorman's first picture.

Thank you....I appreciate the ideas...I have to grade for a couple of hours which is why I didn't remove the "Y" brackets from the frame and they aren't connected to anything...they are just laying there out of the way. After grading everything is coming off anyway. The lifting rod works with the homemade extension for now. The set up for the front of the cub is for another snow plow ...a 54 or 54A, but it is certainly the early model with the horizontal spring...I don't know but it works very well plowing snow.

So I found that funky lift arm and tried to attach it as depicted in the picture. Question I have is should there be some sort of spacer and the bottom bolt?

[Bob McCarty]

Yes, there should be. I've used steel gas line (I think 1/2" (?)) that the bolt would slide through. There was an internal seam that I had to remove with a round file.

5/8" and a good idea

[gitractorman]

Looks like you have it figured out.

[ajhbike]

Yes, I can go with the lift arm or the lift rod. Thank you.

Since I have been doing a couple of drawings and 3D models recently, I decided to revisit this. I did the non-FH substitute drawbar and it's in the pdf section here. Now I'm working on the FH one, and the mount bracket is proving to be a difficult one. I have both Jim's and Peter's sketches, and there are some differences in them. First off, the holes should be either from two planes or in relationship to each other. If the location of the mounting holes are off, then the bracket will never fit. The location of the step up is also critical, since I'm assuming it has that step there for a reason. The location of the axle hole is of some importance as well. I can throw a drawing out there, but I don't have the confidence that it's correct. A drawing that isn't correct is worse than no drawing at all, since it may mean someone will build it to the drawing and it will not fit.

I really need some verification/clarification on this so I can make a drawing I'm confident in, one that will produce parts that fit.

ya, sorry...I haven't tried mounting it on my Loboy with the FH. If there is something you would like me to do or measure then I will try and neanderthal my way through it. John
