tsheahr,I just read the entire thread,and I think you will be absolutely fine with the gen you want to buy. The loads you want to run are easy for the tractor and Genny.Ive ran the loads you want to run with an 8hp Honda 4400watt long run Chicago Pnematic Gen from Harbor Freight.I had to be very careful as my well drew 16 amps to start,and total output was 18 amps.However once running it drew only 6 amps.I went up to a 5500 Generac,which handled it all without manually unselecting circuits,now i use a Northern tool 10K (8500 continous) with 16HP Briggs Vanguard.This gen is about 6 yrs old,and its well built.It easily runs my whole house (within reason).I even ran my 2.5 ton A/C unit with it this summer.You will have more power in the PTO and the gen than i have now,and I dont need for any more power.I keep my voltmeter on a recepticle when im on genny power,and set the low voltage alarm to 115 volts.I set my gen at 124volts with a light load(my utility is usually 123.5).Ive never had my low voltage alarm come on.I have run on gen power for days at a time.My power comes in from an old railroad bed,which the property has been neglected on both side,theres always a tree knocking down lines or a transformer fragging after a bad T storm or a winter windstorm.
The only neg thing ill say about the PTO genny is some of the gearboxes that step up the RPM from 540 to 1800 or 3600 are very noisey.It usually isnt the volume of the noise,its the actual pitch and frequency of it can be irritating to listen to for hours on end. If you can get a heavy duty 180RPM 4 pole Gen,it will last longer in most cases,and the gearboxes are quieter than the 3600 RPM 2 pole models.
