I revisited this today. I found a solution. If you manually open the “covers” on any planter it works great. For the Kenzie or any other that doesn’t allow keyboard commands to open the cover, EasyDevControls mod has a manual open cover command that does the trick. It would seem since that planter uses all the available tool commands (lift/lower, change seed, start/stop, and row markers) having row markers like that, it doesn’t leave any remaining commands for the covers. I hope this makes sense. If you could make the Tender be recognized by the game the same as a pallet of seed then manually opening the planter covers wouldn’t be required. But I failed to figure out how to do that. Regardless it’s usable now with the manual workaround.
