Generac Ultra Source 17500 watt generator model 4583-0.
This thing is a beast. It is rated to run a 5 ton + a 3 ton AC unit. It easily runs my 4 ton and 1.5 ton plus whatever else I can plug in without issue. Will easily run a whole construction site or several homes (depending on AC loads).
50 amp outlet is underneath in the middle.
Always garage kept, run every couple of months (at most - usually monthly), and never left with ethanal fuel (always ethanal free with STA-BIL). No hour meter, but less than 200 hours (probably closer to 100-150). Starts up on first attempt even when cold.
Includes many maintenance supplies:
5 oil filters
2 air filters (with one pre filter)
2 sets (4 total) spark plugs
12v battery charger cables
Many spare fuses (I kept losing them and buying more).
Battery is about 2 years old. I usually get 2 to 3 years out of a battery.
Gas gauge isn't working. The piece to fix is included. I just haven't had time to J-B Weld it back in place.
Break out cords are NOT included, but are available for testing. The transfer switch referenced in the manual is not included (already sold).
