Cub 54 Leveling/Grader Blade

Tue Aug 17, 2004 7:28 am

I've been looking for a Cub 54 blade for my 1949 Cub and visited the gallery at TM Parts

I was aware of the CUb54A blade but it looks like IH had a very early blade for the 1948 and maybe earlier Cubs called the Cub Leveling/Grader Blade. Then according to TM they came up with the Cub 54 Leveling/Grader Blade for models 1949-1952 and then the Cub 54A Leveling/Grader Blade came along for 1953 and up Cubs.

Does it sound like I have pieced this together right or can you mount a Cub 54A Leveling/Grader Blade on any Cub?

Dave. The 54A was designed for the regular cub for both the front mount and belly mount positions. It will mount on all years, late & early. The L54 was designed for front mount on the Lowboy. It cannot be mounted under the belly (Grader position). Not enough clearance. Hope this helps................

Yeah, the L-54 blade is strictly for the Lowboy so I'm wondering just about the C54 and C54A blade.

Dave. Either the C54 or C54A will fit. As you stated, the C54 began production in 1949. The C54A began production in 1954 with improvements in the mounting & probably the better of the two. But, as you were questioning, either could be used on all the regular Cubs...........

There were basicly 4 versions of the blade made for the Farmall and International Cubs, not counting the versions for the Lo-Boys.

The Cub Leveling and grader blade was made in 1948. It is lighter and has several other operational disadvantages compared to the others. It did not come with a substitute drawbar so you were expected to reverse the regular drawbar to mid-mount the blade. The other versions all came with a substutute drawbar.

The early Cub-54 was built 1949-1952. Many of the parts of this blade continued through the latest blades.

The late Cub-54 was built in 1952 and 1953 (and probably in 1954). The changes were largely in the lift linkages.

The Cub-54A was built starting 1954. One reference I have says the last year was 1973. But they appear in much later brochures. Maybe they had a warehouse full of them somewhere. This blade was almost indistinguishable from the later Cub-54. The major difference was the substitute drawbar which was modified for compatibility with the Fast-Hitch. Interestingly enough, the substitute drawbar was modified a second time for compatibility with the later screw type Fast-Hitch, with no nomenclature change.

Any of these blades can be mounted on any standard Cub and mid-mounted using either a reversed drawbar or a substitute drawbar. The only restriction is that if the tractor has a Fast-Hitch, it requires the use of the appropriate substitute drawbar to mid-mount.

There was also an L-54 blade for the offset Lo-Boys. It was built from 1955 to 1973. Front mount only.

The model 54 blade was made for the numbered Lo-Boy tractors. I mention it because it looks similar and people mix them up with blades for the offset models and try attaching them where they don't fit.

Turns out I stepped in it in my last reply here. There is one more catch on the compatibility of the blade to any version of a standard Cub. On tractors without Touch-Control the blades can be used with the same hand-lift parts that are common to many implements. However, the arm on the front rockshaft is enough different to cause a small problem. The large bolt hole in the front arm is positioned about 1/4 inch differently than on the Touch-Control arm. Consequently, the front bolt that holds the bellcrank extension (boomerang) can't be put in. So the blade has to be mounted without the boomerang. It can be used for belly mounting but has to go with only one bolt.

The Owner's Manuals are also unaware of the difference and give the same mounting instructions for Touch-Control or hand lift. Thanks to Tom at TM Tractor Parts for spotting this difference.

I have the blade belly mounted on Scruffy without the "boomerang" and would recommend it. The lift rod is linked to the shorter arm and therefore has a slower rate of travel. It still raises plenty far for transport, but gives finer control.

You have a valid point there. The shorter arm will give you easier fine control. I notice a single rod going down to your blade. Is it one of the earlier versions or did you make up the rod you are using?

The rod is shop built... a little longer than original. It attaches to a shop built bracket on the frame.

One of the pleasures of this hobby is making things that work.

My first grader blade was completely shop built.

George,alot of the custom built things you make are pretty neat.I only wish I had half your talent.....

I think I am going to get that boomarang dang thing.I replaced the tow strap with a chain now. I still need a lift strap and spring.

I Have a couple of front end and belly grader blades here for sale and you are not that far from N. W. Pa. AlBie

I've got a Hesston plow that I can't figure out how it hooks up to my Cub...

I don't have any of the levers or straps to put it on the front, obviously, so I'm trying to figure out how it goes under the belly. I think I might be missing parts for that, too...

All I have is the plow, spring mounted to its own frame, coming back in an "H" configuration with clevis pin mounts on each far end of the "H".

Never heard of a Hesston plow for a Cub. The description sounds enough like a Cub-54 that you should get some ideas from looking at the pictures on TM Tractor Parts.

Well, you're right Jim, I should not assume that it hooks up to the Cub just because it came with it! :roll: :shock:

I also have two plows, one with a disk and one without, that don't look like they hook up "easily". :roll: :?


Sat Aug 21, 2004 10:08 am

Errrrr, what I have looks very little like that, except for the plow piece, and the back ends of the "H" don't look quite like that!

Uh oh... :shock:
