Our generator has been stone reliable (and since we have our own gas well on property, fuel costs are not an issue).
Two things about the Kohler 20RESA and its transfer switch:
First, if the mains power flickers on/off several times in brief succession, the transfer switch gets discombobulated and I have to go out, open the switch panel and press a few buttons to bring it back on line. Has happened 6-7 times in the four years we have owned it.
Second, oil changes are a PITA. Scraped knuckles and some dirty oil spilled are standard features.
Other than that I have zero gripes.
Great feedback... thanks. Your own gas well? Wow... that’s one I’ve never heard before... sounds interesting indeed!
