Reasonable compromises must be made. I won't lie to you, being someone that spent the better part of their career performing manual labor I would find it hard to believe you have spent any extended amount of time working a farm.

The share of people that want to perform, very specifically, back breaking labor is small compared to the number of people that would prefer to do literally anything else. We can make accommodations for that small number bit automating plowing but not science is a reasonable compromise.
