Do you guys run your engine pto at 540 under load or empty on your big augers? I am referring to my 13 by 95 farm king or my 13-94 westfield. I always ran 540 at empty. Is that wrong? Sorry for the dumb question. I have heard so many bad auger stories I hate to screw something up . I have honestly never check the tractor pto under load. I always try my best not to let my augers run empty but wondered if you run a 540 at 640 empty for to long what will happen?
I wanted to try and speed things up at harvest but hate to push to hard and break something!

400-450 pto rpm is where we run ours. Never seem to gain much capacity any faster it seems on our augers. They just make more noise and spray a bit more grain over the hopper.

Have the 16” farm king 1000pto. I have always ran it at 540. It’s nice and quiet all the time.

With all the different augers I have used, gas or PTO I always try to find that sweet spot when it was empty. Basically the point where the flighting is not chattering away in the tube.

biggest I have is 10 inch, both only run about maybe 450 under load and as slow as possible when empty, but then I do the same with the others as well right down to the 6 inch ones. I hate the sound of an auger beating itself up.
Years back when still using old wooden bins, my Farmking 7 inch was chugging along a good clip and I was shoveling, could actually keep up to it back in those days lol, anyway went to go out and push it into bin further and I got hung up on a nail or something at the door trying to squeeze between the auger and doorway, didn't want to rip my covies and while I'm trying to get loose, auger run empty and all of a sudden just began to clatter and shake horribly. The plastic tubing for safety on the shaft running to the top started flying off in big chunck and even had the 12hp Kohler surging as it was under load it seemed. I gave up trying to get loose and reached and got hold of a door board and used it to run the belts off the gear case pulley and brought the situation to a stop. Got myself loose and then looking into what had happened and was just a case of how resonace can get created by the flighting flopping around in the tube. Never hurt the auger, still going yet today. My Westfield TR will do the same thing at high speed, so thats why I am really careful with those big ones. It can destroy them eventually.

Run 16x104 at 1000 empty and load it down to 800 on a 200hp tractor

Thanks Bob, I feel a little reassured as I do the same. I wonder how the companies test the output, underload at 1000 or empty starting at 1000? same as 540.
Thanks to my smart mechanic in Rosenort we did a pto test on one of my tractors and found out the RPM PTO gage was off 275rpm. Basically put some white reflective tape and pointed a rpm sensor to the pto shaft. I guess that is what sparked my interest if I am really getting the maximum output from my auger.
I know this is off topic , but this same situation would apply to many pto driven machines. I was specifically thinking of a rotary ditcher like an elmers wolverine.

PTO speed was one of the questions I asked the Meridian engineer when investigating my swing auger issues. Meridian has a sticker on the auger saying 450 rpm. So I asked the reasoning behind it, basically - what factor determines the max PTO speed recommended. He said that was the speed when the overload door on top of swing should not pop open. And they concluded that by all their testing and experimentation with all grains and elevations. So basically, to idiot proof the auger they recommend 450 rpm max.
Now, it becomes very evident that if you are operating the machine yourself, making observations that take into account more things than a "max 450 statement", then you can run whatever speed you want until something says too fast.
The old mk10 x 70 Westfield would keep huffing more grain the faster I ran the PTO. It was pretty linear based on PTO speed vs truck endgate position. It got to the point where barley wasn't falling out of the end fast enough and had grain shooting up through openings between the metal spout and auger tube. Probably a little over 600rpm under load. Wouldn't do that with peas or wheat, never even tried. But as an operator and doing barley it was a matter of observation and implementation.

Oatking, did he do the PTO speed test under load? Not like it should matter gauge wise if it is under load or not, but curious how he did it. You peaked my curiosity on this when running the bale processor, it always seems to run better at 1100 to 1200 rpm on the gauge.

What’s your engine rpm? Compared to rated speed. When running that fast

Beerwiser, we did the test under no load. I would have liked to try it at harvest time. I really should buy a monitor to measure rpm my self. The PTO speed sticker on the tractor window is far from being correct!
