I have a tiger power 10k it runs everything the house and garage,and a well pump, have it mounted in the garage, have a small door made that i take off and back the bota up to it and hook the drive shaft up and a way we go. longest i'v been with out power is 6 to 7 hrs. love it wouldn have anything else. as for worrying about the tractor coming apart there that chance but very rare one unless it a very old machine all of the compacts are very reliable mine is 13 yrs old and doesn't use any oil. as for the gen it has all the electric bells and whistles. its your money what ever u decide i will be happy for you !!!!
I also have a Tiger Power. Mine's a 15 KW. Messick's sells them, but I got mine from Eckroth in Orwigsburg, Pa. Messick has a good detailed description of them on their website.
I really believe that most of the guys that post negatively on PTO generators don't have one, never did have one, and never used one. That's just my opinion based on some of the comments I've read on TBN over the past few years.
I also have a stand-alone portable generator, an Arctic Cat 4.5 KW. I know you can't compare it to a 15 KW. But it is more of a PITA than it is good. You'd better get ALL the gas out of it after each use. You'd better have FRESH gas when you want to use it. Stabil helps, but it seems not as good as it did years ago. Maybe it's the gas we're getting nowadays. Another thing is where (how far) do you go to get gas when the power is off. We don't have any stations in our township anymore. I have oil heat (275 gallon tank) and have a 55 gallon drum filled for tractor use and so have plenty of fuel for the tractor.
We have an event here that we do each year called "A Night in the Country". The Ambulance Corps, Fire Companies, local businesses, & charitable groups set up fund-raising & informational stands. They use portable generators for lighting. This is one place a stand-alone generator is good for IF YOU CAN GET IT TO START! You should see some of these people when theirs won't start. Small gas engines, especially ones that don't get used & maintained regularly can be a problem when you need them.
I've been around & operated several stand-alone generators over the years (almost 51 years old) & none have impressed me. On many of them the lights flicker & they don't seem to put out good "clean" power. That's just what I've seen over the years.
On the Tiger Power PTO generator I have, I can't tell the difference if I'm on Met-Ed or the generator except for the fact that I can hear the tractor running.
