PTO generator?

I have a 15000 watt generator. It won?t run my tombstone welder nor evidently a submersible pump! Dropped the pump down 100 feet and I got 1 spurt of water now I can hear the tractor pull down just a bit but no water. I probably screwed up, because I used 1 1/4 pipe that I had to go down the well. It?s HEAVY! I tried to pull it back out and am going to have to recruit help.
Now my question is- what or how big of generator do I need. Would really like to be able to power my welder, well and the house if the power goes out.
I really thought 15000 watts was enough, but the amperage is not enough, evidently.
 
15000 watts is more than enough to power either of those loads individually, and likely both simultaneously. Did you have the RPM of the tractor up high enough to achieve the 60hz frequency? The well pump would likely run, but at a reduced speed, thus not moving as much water. It sounds like multiple issues from your OP.
 
Also how many hp on the tractor, should be at least 30hp. Silly question by today?s standards but still a part of the equation.
 
15 should be plenty for your well and house,how many amp is on the breaker for the welder? Multiply your voltage (likely 240v) by the total max used amperage (likeky minimum 25+ under a decent load) and that will give you your consumed wattage. Ie say 240v drawing 30 amps consumes 7200 watts alone on the welder leaving you 7800 for the rest,still should be enough if everything?s working properly unless you use a lot of electricity in the house from electric heating sources.

I agree with the others that a 15kw generator is more than enough to do what you want to do. Think of it this way: 15kw is more than you would have in a house with a 100 amp service. ie, you could run a whole house with a 100 amp service and still have some left over. My best guess is there is something wrong with the generator.
 
Its not like your trying to run the pump with marginal capacity. Guessing your pump is 1HP or less your generator capacity is many times over large enough and if your tractor has enough power to move on its own it has enough power to run the 1HP pump. I think you have generator issues but it's a pure guess based on a small amount of information given. At the least you need to get some voltage readings and hertz would be peachy. Check at the generator with no load and when you apply a load.
 
DC Case, on the front of it. 35 hp?
I took the generator into the local shop and they said it would only produce 27 amp? They could not get it to run a stick welder either.
I had the DC full throttle. The needle on the meter was in the green.
I will have to look to see what brand it is. It?s a ?double barrel ? style.
 
Something is wrong if you can't run the pump.
My experience is buzz box welders are hard to run on a generator.

Is the pump wired to the correct voltage?

One of the best purchases I have made is an engine drive welder. Welds really well, and is my backup generator. Will run everything we need in the house.
 
I also have a PTO generator, rated for 540 PTO. I hooked it up and it would put out 110 but would not go 220. What is the out put of yours? Might check that before you go any farther. One of you coil might have gone South.
 
If you want to find out what is happening, you need a clamp on amp meter, (Amprobe is a brand name like Kleenex is a tissue) if a repair shop says they can't get more than 27 amps out of it, the voltage at that point may have been down to 30. It is neither the tractor, nor pump that is the issue. If it is showing load on the Case engine, I would say it has a short internally. Jim
 
Ok ,you?d think it?d be good for at least 50 amp,either that?s all it?s rated for or it needs serviced.
 
Something doesn't sound right.

I have a 10KW generator, and it runs the pump OK. But, my well is only 35' deep.

Before I got the generator, a friend that works for a local electric power company estimated it would take 6KW to run my entire house, well included, but excluding the electric clothes dryer and the A/C. When I'm running the house on the generator, the lights have a very slight blink when the well kicks on, that's all.
 
We can all sit around guessing what the problem might be. But until we know what he has and his load is.We are all wasting time. I have been at this for 45 years.You need to know what you are working with.
 
Agreed - but I would be almost certain there is an issue with generator output - not an issue with the load from the welder or the pump. If a correctly functioning 15K generator can't power them I doubt they would function correctly when hooked up to the local supplier.
 
It?s a Generac blue one. I hooked the 830 up and can?t get the needle into the green. Checked voltage with a cheap multi meter. 1 leg is 120 the other one is under 100 volt.

I see the problem
1 It is a Generac.Those of us in the repair field call Genajunk.
2 It is a Generac Twin.
Two 120 generators tied together.One gets more load than the other. It will burn the other out.A very bad idea from them.Parts have not been made in years. If at all. I have had several in the shop. Some parts were almost the price of a new unit.Best thing I can tell you is to buy a new Winco unit.If you want something to depend on. Maybe a good used one.

Just being honest with you. You could call genajunk. But they will most likley hang up on you.
 
(quoted from post at 17:08:38 12/24/19) That?s not what I wanted to hear but it is what I needed to know. Thanks

Need to measure voltage and current with a small load and then gradually progress higher .
Thinking dirty slip rings , dirty/broken/stuck brushes . Or a failed excitation electronic board .
Generic Regulator boards are low cost on eBay.
 
I know it is not what you want to hear. I wish I had better news. I wish I could fix it for you. But I have seen too many failures. You might try taking the covers off. Checking the connections. You might get lucky and find a simple fix.
 
Billy, Winco has been the gold standard for years, but recently they announced they will no longer be winding their own generator ends. They will now be purchasing them. I guess they will be a "builder" instead of a manufacturer.
