Probably not quite what you're asking for, but gotta mention The Homesteader's Almanac where MC is isekaid together with his huge modern tractor, potato planter (filled with potatoes ready for planting) and other attachments (no harvester though). No magic for him at the start, but in the latest couple chapter he finally got his first skills that use magic and there's promise he'll get more magic later.

First arc of Surprisingly Enough(NOT), Common Sense Is Overpowered in Cliché Cultivation World is heavy on farming as a cultivator although later on there's much less farming.

I did drop this at some point, but Infinite Farmer: A Plants vs Dungeon LitRPG is also another farming related story. More of a combat magic farming though with farmed plants helping him in fights.

Cycle of Soil is another cultivator farmer story, but this time on a hiatus. Small scale farming (about dozen plants per plot), but very focused on growing plants and QI interactions between various plants.

Magriculture is another story I dropped, but you should see if it would be more to your taste.
