Maybe that's what he enjoyed. Farm work is hard, but it can be very enjoyable as well.
If he loves the work he will be able to find it, hope he does.
It may be enjoyable for some but not that I have heard, my mom was in the cotton fields from age 6 to 16 during 1935 to 1945 never touched a garden again the rest of her life. My girlfriend grew up on a farm and does not speak fondly of the work she had to do as a child. Both hard workers but not on a farm.
