My father has an International 154 Lowboy Harvester Tractor and he's having some electrical problems with it. I'm trying to obtain a wiring diagram for this tractor. I contacted the company buy haven't heard anything back. I don't know much about these machines so any help would be greatly appreciated. I hope that someone out there can help me!
That is a very basic wiring system... what problems is he having?
The IH cub F model is about the same..
You will find a wiring diagram posted on this link: http://www.farmallcub.com/phpBB2/viewtopic.php?f=31&t=17184
If you don't find what you are looking for post back... I believe I have the complete service manual. KennyV
Thanks for writing. I printed off the wiring diagram that you posted the link for and it's currently in the mail to my father. As far as his wiring problems, I think that he said that something caught fire so now he has to replace a bunch of wires. Doesn't sound very good!
Where did you get your manual for this tractor? My dad would like to purchase one - he actually asked if you'd be willing to sell yours to him? I doubt that you'd be willing to sell yours but I would like to buy one for my dad if I can locate one.
My dad said that the diagram that I gave him is somewhat useful but that it doesn't show the connection between the key & the starter button. This is where he's having the issue I guess. Any other ideas of what he can use to fix this?
He also wanted me to clarufy that he has a cub lowboy 154 4 cylinder motor - in case you are able to locate a manual for him.
Well, the fact that it is a IH 154 Lo-Boy says it will be a 4 cylinder, L head water cooled engine.
That tractor uses essentially the same engine from 1947 through 1980. There were minor changes, piston shape and carburetor made the 1977 and later around 14 HP.
The Lo-Boy variation of the standard cub was introduced in 1955. It has shorter front spindles and the final drive was rotated 90 degrees to lower the tractor 8 inches.
Original color was Red, that changed to Yellow and White in 64, then in 77 they changed it back to Red.
The major changes to the electrical system were made in 1964 and in 1968... Those changes were a switch to 12 volts and then the addition of an electric clutch for the PTO.
There were a few variations in the available attachments that were not interchangeable after 1968 when the offset 'frame' disappeared, and that is when you could have the 154 LoBoy, 184 LoBoy or the 185 LoBoy... These were all the same tractor with some changes made to accommodate different attachments, usually all mowers.
To get to your wiring question... Power comes FROM the large terminal on the starter TO the ignition switch... FROM the switch TO the starter button... FROM the starter button TO the starter relay.
The charging circuit was also fed FROM the ignition switch along with any other accessories like lights and PTO clutch were fed FROM the switch to fuses then the acc..
These are fun little tractors, and are tooooo handy to have around:smile:. any thing else just ask:thumbsup:.
How long has your dad had his Cub? KennyV
