International cub lowboy

Postby Basskicker » Tue Jun 23, 2020 6:47 pm

I have an international cub lowboy I’m trying to positively identify the year and I’m having issues.
The vin plate is international cub lowboy and the serial is 755. What’s confusing me is:
1- the 7 is half the size of the 5’s
2- to my understanding, block and trans numbers can identify the year although previous year may have been used, the numbers on each do not match but all are labeled as “R” which I learned is 1948.
But...Farmall dropped their name off in 1955 for the low boy.
Front axle is extendable and wasn’t used in 1955 and on for low boy.
To add to the confusion, original owner was a designer for international harvester at the time.(now deceased)
Also he has a 1948 IH prototype truck in the barn that hasn’t seen daylight since the early 70’s
Wondering what I really have.

Any pictures? Do you have an offset LoBoy or number series? Need more info for identification.

If offset your post should be in the Farmall Cub Forum.

Welcome.

The identification of one of International Harvesters Cub tractors does get confusing. Photos as Stan suggested.

To make things more confusing is that parts are interchangeable for the different Cub tractors. And then the serial numbers started over with a newer model of the same tractor.

The R you mentioned is probably stands for revision, meaning the part was changed.
I have an excuse. CRS.

A date code will look like 6-24-L. Which is the month, day, year the part was cast.

A part number will look like 123456R2, where 123456 is the part number, and 2 a revision of the part.

Your probably correct, I should be on the Farmall cub forum,it is offset,I figured it IS a 1955 Lo-boy But the serial number is the biggest question mark.
755 J , the 7 is half sized, if it is a prototype, will converting it to 12v effect the historic value?
I’m doing some mechanical restoration as it has not been used for 10 years. I can post to the Farmall forum also, but I cannot do attachments yet.

755 J would be an early 1955, IH started them at 501. The ‘J’ indicates Rockford clutch versus an Auburn clutch.

Since your serial number falls in the production range - not a prototype.

Why the 7 in the serial number is under sized? Don't know. Perhaps the person stamping the ID tag used the wrong punch.

Historic value. My opinion, the only Cubs with a historic value are the first of the model and last one. But some folks might consider an early production low-boy worth a few dollars more.

Thank you everyone for the valuable information, found by looking at the right block embossing of 8-22-A, it is indeed a 55, doing the 12v conversion, Fuel system flush, tune up kit and loosening up the stiff joints, the most work she’ll see is plowing snow and leveling a 1/4 mile gravel driveway, next post I should be able to show a pic :D

Hi,
The Cub LoBoy operator's manual can help you learn about maintenance that the LoBoy needs.

Below is the 1957 LoBoy operator's manual. The experts on here recommend people read it. It has lots of info about operation, maintenance, and lubrication. There is a table of contents on page 1.
It shows how LoBoys originally looked in it. The lube section begins on page 21.

http://farmallcub.com/rudi_cub/www.clea ... index.html

This manual shows the electrical system that a 1955 LoBoy originally had.
LoBoys made before mid 1964 originally had 6 volt, positive ground electrical systems.
If the 6 volt system works good, it doesn't have to be converted to 12 volts.

There is an Extra Equipment and Accessories section, beginning on page 71. There it shows the adjustable width front axle was available.

The recommendation in the manual to use Touch Control fluid in the Touch Control was changed later to Case IH Hy-Tran fluid. It is sold at Case IH dealers.

I would check or change all the oils before using the LoBoy. Using it with low oil in a gear housing can damage the parts in the housing.
There are 3 separate gear housings, with 3 separate oil levels to check, in the rear area of a LoBoy, the transmission, and 2 final drives.

The transmissions in LoBoys commonly get water in them, from rain, or condensation inside the housing over time.

Below is a post I made telling about the date codes on Cubs and LoBoys, the post is the 2nd post on the page. :)
