PTO generator/shaft question

[SPYDERLK]

Good tip. I saw somewhere within 10 degrees. It's nice that you mentioned it in case I hadn't. No welded legs though. I figured one leg on the tractor side of the carry all to bolt on in the middle. That will prevent any drift down, which my 3PH never does, but just in case. And that will allow me to still lower my carry all to ground level for dragging heavy stuff onto it, like the generator. I'll have the generator bolted to a piece of 3/4" plywood or something. Eventually I might make something just for the generator. Something like the 3PH stand on the site I am buying it from.

Thanks on the generator. I'm hoping it's as good as people have said of the NT one, and it's cheaper and made in America.

PTO shafts that run at a fixed angle should be well off 0 degrees/straight. Straight does not get the ujoints to move enuf the keep the lube refreshed on the needle bearings. Give it several degrees ... up to 10.

I was going to build the carryall to use for other stuff, too, since the generator is more for emergency use and hopefully won't be used as much as the carryall. That's why I did not want legs on the carryall to hold it at a pre-determined height. I want to be able to lower it to ground level.

I was going to bolt the generator to some 3/4" plywood that is bolted to the carryall. Are you saying that without legs the carryall could twist when I start the PTO and run it up to 540?
I realize that the lower arms are not "locked" and can be raised by simply lifting manually, but I didn't realize that running the generator would create more torque/twist than running a rotary cutter or other implement, which I've left running while lifting it up. They don't twist, but they are a lot heavier, too.
Am I understanding you correctly?

I have no trouble running mine held by the 3ph as you seem to be planning. doesnt need a leg to sit on really. I put my gen on a pressure washer cart and adapted the cart to the 3pt. Easy to wheel to the tractor. Then the tractor handles it.

I didn't know that about U joints, Spyder. I wonder if that's why the shaft labeled for a generator is so much more expensive.

ZZ, a generator can flip a trailer?!

Fred,

I have only operated my PTO generator with the legs , it came that way..but on start up there is a strong jerk or twist to it and then it smooths out once it is up and running....I have never run one without the legs and some ground contact for stability...If you look at any of the ads for these things they either come on trailers or have legs and I can see why....

I would call the company you are buying the genny from and ask them..but I would not want to try and fire mine up without support of the 4 legs or a trailer or I can see where the whole thing could flip over and turn with the PTO until something broke....I'm just saying......????

That's what I was hoping to do. Use the 3PH to hold it while it's mounted on the carryall. I've seen dedicated generator stands and they don't seem that substantial, but if it can flip a trailer... That's bizarre, I had no idea that even a bigger unit had that much torque.

A call to the company is definitely forthcoming ;^)

If the gen is attached to a mounting that is attached to the 3pt it isnt going anywhere. It may jerk when you start, and jiggle a little while its running, but there will be no catastrophy. If it vibrates enuf that it seems to be likely to cause trouble youll be able to try different rest strategies. I think a tire carcass would be a possibility.

Thanks for all the advice guys.
I just got off the phone and they said I should be fine. He said he's never heard of a generator flipping a trailer, not that it couldn't happen under just the right unfortunate circumstances, but I should be good with my original plan. And I never run my tractor up to rpms and just dump the PTO, so I should be able to see anything out of sorts as I bring it up to speed.
