I've cut and pasted various bits from my reply on AIBU, and will now add to it here Kiwimum.
As I said previously; I feel qualified to comment on your OP, as I am married to a farmer and we run the farm between us. We were also an all year round calving dairy herd before we sold the milking cows in Dec to concentrate on arable/sheep.
My DH is traditional in his outlook, in that he was brought up to believe that he provides for his family and his wife should be SAH and supported/provided for & the majority of housework/cooking/etc is done by his wife. He gets up at 6am and probably works through until 8pm most days on the farm. I tend to do all the office based work, so I am more SAH.
BUT and this is a HUGE BUT - if I am out, or away, or doing something else, he is more than happy to help. For example, he'll put the washing machine on if I ask, unload the dishwasher, put the hoover around and generally help with domestic tasks, because we're in a partnership. he's also capeable of getting his own lunch, cooking dinner on his own (not that he does very often, but he does). (All this info is just to give context of my daily farming life, BTW).
Once I had posted on your original thread on AIBU, my DH walked into the office and asked what I was doing. So I showed him your OP. Bear in mind, my DH is a farmer, who routinely works 14 hour days, 7 days a week and until last December, all his life had been a dairy farmer milking 120 cows on his own, 2 x a day, every day on top of routine farming tasks... (i.e. he works bloody hard).
My DH was absolutely disgusted at what you have to put up with and actually commented that you didn't live with a "man, you lived with a "childish bully".
It sounds to me, as if it's not his dairy farm but he's the leading cow-man with proper holidays? Or is it a spring calving herd, that is dry 4 weeks of the year? Either way, it's irrelevant, because quite frankly, your husband needs a bloody good kick up the arse. You can have very successful "traditional" roles within a relationship (mine is and it is very, very common to farming families) but that doesn't stop you living in an equal partnership. You are not some unpaid skivvy. You are his wife. You are equal to him and TBF, his behaviour is totally and completely unacceptable.
My DH made the comment yesterday that I had forgotten to water the plants outside (a job I usually do). I told him that he knew where the hosepipe was and that he was capeable of using it... I didn't get a tirade of abuse for that, like you seem to for every little thing - my DH went and got the hosepipe. That is normal.
Regarding the plate issue and putting it away by the end of the night - that's not OCD about tidiness, that's blatant control issues!
Have you thought that the bullying of you is precisely because he can't do it to staff members? Redirected agression & control?
What ever the case, you need to SERIOUSLY assess your relationship and work out what it is you get from it, because what you describe is not the actions of a "busy farmer wanting downtime", it is the actions of a bullying tosspot who needs a bloody good talking to.
