It’s really not as simple as that : modern farming techniques and automation made being a farmer mostly useless, as evidenced by higher crop yields and lower numbers of farmers. However it made farming equipment mechanics and engineers more useful; it made farming equipment sales managers more useful; it freed up labor to be allocated elsewhere (or in a free market sense, more incentive to do something other than farm made it profitable to do so).

But that is not what happening in reality. In reality farmers are obliged to buy seeds from "approved" sources, forced to pay for "vaccinations", forced by machinery manufacturers to vendor lock without having a right to repair and so on. Mechanics are got rid because they can't repair vendor locked machinery, engineers can't apply their skills without tons of senseless regulations, even agronomists losing jobs, because there is nothing to manage on strictly controlled by government farm where some legislative papers dictate you what exactly you should sow and where and seeds manufacturers that force you to follow their guidelines to be allowed to buy seeds next year. You can't breed your own varieties of plants anymore. Even fertilisers are strictly regulated. There is nothing to do for agronomist any more on a farm.

But at the same time, the army of law enforces and supervisors from government and corporate sector is growing with insane speed. Even lawyers are breeding in enormous amounts to help corporations to sue you for "unapproved" repair or keeping your own seeds.

Technology bring a lot to a farmers, and if we lived in some another world, things could be as you describe. But in our world, technology was hijacked by greedy elites obsessed with idea of total control over humanity. So, no, when farmer buy a new tractor, it is not a new regular service job for village mechanic, it is a village mechanic starvation, along with more money farmer have to spent on service and repairs, because new tractor could be repaired and serviced only on authorized corporation service station only with corporation spare parts and only as expensive modules. And farmer have to pay them full price for whole diesel high pressure fuel pump instead of a single valve piston or even just a small gasket.
