That's the issue with most of these threads.
the people that are against the use of a tractor mounted pto gen are of the mind set that once you hook that pto shaft up to that generator that the tractor becomes an immoble lump of metal that is 100% incapable of moving untill the emergency is over, and must run 24/7
Both are bad assumptions.
1, as most of us know that have actually been thru extended ouutages.. yuo rarely run a genny 24/7.. and usually much, much less.
If you practice good refer etiquette and don't stare in the door of the open fridge for 30m while you think about what you want to eat.. it will actually stay cool realy really well!
powering up the genny 3 times a day for an hour at a time is plenty to keep the refer cold, and for rationed water use, you can use that time to pump up the well, and here is what we did. of the 3 hrs ( max.. usually a bit less ). run time.. we used 2 of those 1 hr blocks to run watr as needed. baths.. dishes.. some clothes washing, before the gen went off. all water topped off at the pump.. in drinking coolers, and a tub poured for emergency use.
the last hour run was for the hot water heater to heat up that pumped up tank.
we had no problem with 3 seperate hours of run time keeping the reefer cool.
heck.. after a few days in that ear 2 week outtage the perishible food was gone in 3 days anyway.. as you learn to eat all that first anyway...
that leaves 21 hours the tractor does not have to be 'useless' like plowing snow.. or digging up trees, digging drainage.. etc.
if you live in an area where you will freeze to death in a couple hours without utility power.. then i'd reccomend a dedicated alternate power source FULL TIME available. maybee a wood stove. or a household genset ).
If you are on life support equipment.. .. the same reccomendation. IE. if you need 24.7 power to stay alive. get a permanent install setup. the other 99.89% of people can do with breaks in power if they act wisely and conserve their resources and manage thier backup power generation capability.
During the florida hurricane festival in 04 and 05, pto gens ran my house and my stepfathers house for right at 2 weeks. we rationed fuel and ran them as needed. we also had use of the tractors the other 87.5% of the time as needed. IE. dragging downed trees out of the drive and off the local road.
Nothing other than foot or bike traffic could get within a mile of my parents house due to large oaks down over most of the roads in our rural city and sourounding county area. When i went over there. i literally had to park on a roadside ( like many others! ) and walk 35-45m to get to my parents house to setup thier pto gen on their tractor.
Made due... no freezing weather.. but flooding and wind damage was all around you.
