First Time Tractor Owner Needs Help with Case 930

Hey everyone. Just bought my first tractor knowing it needs a little work. Here are the issues with the Case 930 diesel;

1. 3pt hitch won't lower. I do know that the remotes work and have the correct pressure that they should. Is there some sort of valve that could just be stuck or gunked up?

2. PTO will not stop spinning. I can turn the shaft by hand when the tractor is off. When the tractor is running, If an implement is hooked up to it and the pto is off, it wont spin. Is there some sort of brake or clutch in the pto housing I should check out?

3. Lastly, on start up I get an intermittent pop and puff of white smoke for about the first 5 minutes. After that, no more pops or smoke and she runs really strong. Any ideas?

Any advice will be greatly appreciated.

Thanks.
 
Do not know about 1 or 3, but for 2 there it sounds like your PTO clutch needs adjustment. It requires a special tool that can be made from a piece of 3/4" wide flat steel. Basically there is a spring loaded pin, use your tool to pull the pin out, then turn the PTO shaft. As soon as the shaft starts to turn, release the tool and when the next alignment hole comes round, the pin will drop in and lock. This is explained in the owners manual of the ITE shop manual.
 
As for issue #1 check linkage from lever to control first. If all is moveing you may have a stuck load valve or the rockshaft/piston may be stuck. put some down force on the arms and see what happens. As for #3, I wouldn't get to worried. The engine has precombustion chambers and that is the nature of the beast, but could also be a fouled injector. Does it wet stack? As for #2, here is the PTO clutch and PTO brake adjustment procedure fron the op manual. I would say from your discription that just the brake needs to be adjusted.

Thank you very much, great info. Tomorrow I will check the things you mentioned about the 3pt hitch and adjust the pto brake and see if that does the trick.

Much appreciated!
 
There is a chance your 3PT is stuck in the raised position because of rust. It happened to one of my 930's. I didnt use the 3pt for about a year and the next thing I knew the 3pt was stuck in the raised position. First check the linkage and if everything is ok then; Place the 3PT lever to the lower position and then apply weight and see if the arms will lower.

Another comment answered your PTO question.

As far as the pop and smoke when starting question I think you may have a dirty injector.
 

Thank you. As you guys suggested, I worked on the linkage and am able to get the 3pt to go down when I get a little weight on it. However, shouldn't it lower even without having any weight on it? Also, I have attached a picture of a small lever located under the seat. There are several positioning holes this can be moved to. What part does this play with the raising and lowering of the 3pt?

I adjusted the pto clutch brake. Initially when I started the tractor the pto was no longer spinning. After I engaged the pto and then disengaged it, it just continued spinning. I probably have about 1/4" of adjustment left on the adjusting screw. Should I continue to adjust it in?

Thanks again for all of the help. I have ordered a manual for the tractor, just haven't received it yet.

That lever controls the sensativity of the DOM system. Extreme rear allowes maximum reaction to draft loads on the hitch arms, such as a moldboard plow. Causes the arms to raise and transfer weight from the plow to the rear of the tractor. The exreme front setting locks out the senseing, and you only have position control of the arms.

You are welcome.
We are all cyber kin here on the CASE forum. If you get a chance, post some pics. and give us a bit of info as to where you are located and what you do with your 930.
As you may have noticed, we BS about our activities etc.
Don't be a stranger, even if you got a neet pic. of a JD tractor stuck in the mud. HeHe.

I will keep my eye out for some stuck JD's! I am near Lenoir, NC. Just moved down from Wisconsin (grew up about an hour from the Case plant.) We are just getting our little farm started down here. I have plenty to learn. The Case will be bush hoggin', cutting and bailing hay, plowing, planting, and pulling kids on hay rides!

That brings up another question...I am in the market for a plow. I know that it can pull a 6 bottom, but I don't need one that large. A neighbor has an older Ford 2 bottom in good shape that he wants $250 for. Are there any issues pulling a 2 bottom with such a big tractor?

Well, I don't think you will need to put the 3pt in max sensitivity to pull that plow. You will have to narrow up the tractor wheel spacing to minimum width. Yo have PA rears, but narrowing the front axle could be a problem. I also think that the first significant rock or root that you tie into will bend the plow. I would look for something designed for your tractor. Older 4B semi mounted plows should be available in your area for a bit more money.
That is a nice sharp looking 930. I have a 1969 with a factory cab.

A 6 is pretty optimistic. Only in perfect conditions. A general rule of thumb is if it won't pull it at 5mph, you probably shouldn't be pulling it.

I think for a small area a 4-16 would be a much better choice. case, MF, White, Oliver all had a good quality semi mount plow that shouldn't break the bank.

First time you hit anything with that 2 bottom, it is scrap iron. In addition, it will never work "right" as your tractor will be too wide, and the 3 point hitch the wrong category.

Thank you. The cab must be nice in winter time.

I would definitely like a larger plow and will keep looking.
