Case SI PTO

[harris19c]

Hello everyone. I'm new here and have found a lot of interesting information. Seems like a great resource.

Anyway, I am about to join the ranks of old tractor owners and buy my first. Just looking for something to use around my property for random odd jobs. I am looking at a case SI model. Everything works well and it is cheap money. My only concern is the lack of PTO shaft on this tractor. The guy says it is a 1955 model and that the small cover where the PTO would normally be, can be removed and a shaft can be added. I haven't found much info on how to so this, what I would need, and even if this is possible. I have worked on cars my whole life and am not afraid to get into any type of project. I just don't want to buy this machine if I won't be able to eventually run any PTO driven implements.

Any help or advise or shared experiences would be greatly appreciated.

Thanks,
Chris

Welcome!

Something to think about if running a lot of
pto is a live PTO. It makes handling a mower
easier, handle a rototiller easier etc. I
don't think that the SI ever had an option
for live PTO, but I may be wrong. I'm sure
nutty or Jon Saeli or Don will chime in.

I have ttried to find that info too. From what I can gather, the live pto was an option. In all honesty, the main thing I plan on using is the loader on this machine. I just would like to have the option of being able to have the pto to hook other implements from each to time. But it wouldn't be on a regular basis. I will mostly use it for moving fire wood and snow and brush and rocks and such around the property. I know these aren't high horsepower machines. So I'm wondering if I should just pay more money and get something already set up for it. But I do like this machine and have never really been a Ford guy. And as far as cheap tractors with loaders in this area, most of them are fords

1952 and later will be live pto and eagle hitch capable. The pto parts from an SC will fit the SI whether or not it's live pto. You wil need Live pto parts if it is
52 or newer and non live pto parts if its 51 or earlier.
Because of the confusing and different methods used to determine the correct year a lot of times sellers are incorrect on the year. If you post pics we can tell you
if its live pto capable.
If the first 2 digits start with 56 or 80 it should be live pto capable. A small number of 55 beginning serial numbers may have live pto and eagle hitch capability.
Up to 56 beginning serial numbers subtract 4 for year; 56-4= 1952
80 beginning serial numbers require a book, but start in 1953.
PTO parts are not hard to find for the S series.
If this tractor is Live pto/eagle hitch capable I would look for a parts SC with these features. The eagle hitch on the SC is slightly different but will work if you shorten the lifting rods. Also you will have to make bushings for the rockshaft as they will likely not have been installed.Eagle hitch was Case' version of the 3 pt and will make your tractor much handier.
If you get the tractor I have the parts you need for either pto set up.
Good luck and let us know what you decide.

Nick, thanks for the info. With that being the case, I will be buying this machine. Besides needing 2 front tires and a small radiator leak that I think I can fix without replacing, this tractor is all there and in pretty good shape (especially considering the rust that plagues things in western mass). I think I can talk the guy down to about $1500-$1600. So I don't mind putting some money into it. The loader is the key part and that's all there and works great. So Monday when I go get it, I should be able to get more info off the machine. Thanks for the help. I will be in contact with you for parts once I have it and see what exactly I need. Everyone here seems great. I couldn't ask for better resources to turn to while entering the world of old tractor ownership

IF you buy this machine, you will jump from being a tractor owner to being a rare tractor collector.
The 'S' series was built in a number of versions, each design made to serve a specific task. The much
more common SC was useful doing a lot of routine farm jobs. Differing greatly, the SI is the industrial
version and could be had with a very heavy duty loader. If placed side by side you would see huge
differences between the two machines. Loader and bucket contents required big front tires and rims on
a rugged axle connected to a different front end. A list of these differences would be long. Because of
the loader, a large cast iron counter weight would be attached to the rear end of the loader frame
preventing the PTO from being used.
an SI tractor with loader is a very unique machine and therefore collectable. If you decide to restore
and show this tractor, another one like it would be a rare event.. Because of this I would recommend
against adding the PTO. I look forward to hearing about and seeing pictures of your project.

That is good to know. At the moment, there is no cast iron weight, but what I thought to be an extremely large concrete weight that is on a frame attached to the frame of the tractor. I believe it was a lull loader on it that the owner says was original to the machine. I have no idea though. It does seem larger than most that I have seen on similar sized tractors. And it goes higher than I expected it to. I hope to get some pics up on here tomorrow when I pick it up.

So I picked it up today. Thanks to the info you guys gave me, I realized it is a 1951 model. The first two digits of the serial number are 55.
