Not personally, but my father did the same thing in the 90s. He went to consulting 4 days a week and running a 100 acre commercial farm the other 3.
I would say there are some synergies in that engineers have access to capital that not all farmers do.
Burnout is a risk and it takes a special kind of person who is a glutton for punishment. If your farm is more recreational, this could be less of a challenge.
As he aged, farming became more of his identity and his farm employees became more of a family and some of the most important aspects of his life. I think this is was a positive development and am glad he has this surrogate family.
In the long run, I dont think it was a wise financial move, as he sunk close to a million into the farm in the 90's, and the long term value of the farm will be destroyed by California regulations. A lot of heartbreak on that front. From the outside I think it is causing more anguish than loosing his parents.
If asked, I think he would still do it all over again.
That said, my 02c would be to keep in mind how much of your life are you placing in a basket and what the threats to that basket are.
