3 Pt PTO generators
I changed my mind. After realizing that I keep around 50 gallons of fresh gasoline in the fuel tanks of my wife and my vehicles I ended up buying a sears 4200 watt gasoline generator. The availability of fresh gasoline, and sears practice of keeping parts available forever (at least it's that way on every other sears piece of equipment I own), were the deciding factors. I also bought a hand pump at Quality Farm & Fleet to siphon the gas from the fuel tanks. But I still think that someone should be building a 5KW pto driven, portable generator for the thousands of smaller diesel tractors around the country.

3 Pt PTO generators
I have also considered a 3-Pt generator, and got some info from an elecricalengineer. He warned me that a potential problem may arise due to the fact thatthe speed of the tractor engine isn't controlled by a governor and may causefluctuations in the frequency of the current (60hz/ 50hz etc.) when load. This may possibly be harmful to some motors and appliances. PTO generators were designedfor steady current applications like lighting. I am only passing along info which I have been told. Does anyone have any other input?

3 Pt PTO generators
i recently purchased a pto gen 25kw,the cost between the 12kw and 25kw is only about $200 i purchased a generac,has both a frequency and volt meter that you can see from theoperator seat. these units are used heavily in farm countryfor backup power, and have been proven to be very reliable.i also dont want to service a motor that would rarely get used,and most likely would not work when you need it the most.diesel tractors are about as bullet proof as you can get,buy a coleman if you want, these are light duty units, meant for non critical use, there is a world of differencebetween the two units, as far as service life, construction,servicability

my pto generator is a generac 25kw unit, has both frequency and voltage meters facing the operator so you can adjust the outputfrom the seat of the tractor, i understand as long as you stay+/- 2% on the output you should be ok.

Coleman generators are not the best quality available IMHO ....What more can be said.

Frequency poses a problem with high capitive loads such as flourescent lighting etc. Some lattitude is allowed with electric motors. WITH capacitive loads, commercial suppliers are allowed .25 cycles either way. Regardless, a brushless generator will be somewhat cleaner that with brushes. However, most brushless units I've seen are large pieces of ___. i.e. Generac, Coleman etc.<---------Not the Best there is.

Could you comment some more on brush type vs brushless generators?Price and quality? I'm tempted to go for the standalone Lincoln generatorwith its own 16 hp engine. I believe it is a brushless....but not sure. Ibelieve that the Honda AC generators are brush type generators. They are moreexpensive for the same output.....which seemed odd to me. This standalone generator thing is a little off of the compact tractor theme,but we might be able to transfer some of the knowledge to PTO type generators.Right now I am sort of lost on what makes some PTO generators better than others......or if there is any real difference.

3 Pt PTO generators
Glen,I have a New Holland Sub Compact and my diesel engine has a governor on it. It holds the speed much better than any gas engine ever could. I don't think your friend, the electrical engineer, has had much experience with tractors. Any motor that you overload, beyond its torque capability, will loose speed and cause frequency fluctuations. But if the generator is sized to the PTO output horsepower, the engine should be able to maintain the frequence quite well. An awful lot of farmers use these to power various equipment, depending on the type farm it is. If what your friend says were true, a lot of farmers would go out of business buying electric motors. Electronics are much more sensative to over or under voltage than motors are. We have run some motors 20% over on frequency. It doesn't hurt them, they just run faster. Ask him if he ever heard of a frequency controlled AC motor. We have frequency controllers on many motors and run them down to 15 HZ, which doesn't affect them either. You will never see that much difference in a PTO unit, so I wouldn't worry about it. The Coleman units will probably give you more difference than the PTO units. By the way, I am a Electrical Engineer too.
