Here is some more info on the Tractor.
This morning I tried it again and found that it appears to work as expected when Bella is driving it and I have no mods in. I will test it again later today as I have had it work on the odd occasion before and then it deletes the tractor again so I hesitate to say it isn't broken. I have lost far too many tractors to this issue to imagine that it isn't happening.
The information below is based on my experience with the tractor when it first came out.
I've only tried the tractor in one game with one family.
They are in Lunar Lakes.
The family is a human, a witch and 2 fairies.
One of them used the philosopher's stone to bind a ghost. (I'd never tired to do that before so thought I'd give it a go.)
The list of available ghosts included Bella Goth.
She joined the family as a playable ghost.
One of the other sims made Ambrosia and Bella ate it.
All sims visited the future a few times. I don't remember how many.
The tractor was released. I purchased it.
The lot the family was living in was too small for the tractor.
I used CAW in game to add a new 64x64 lot to the game. It was winter in game so I build a large building.
I used the growing mats from Into the Future EP.
I placed a tractor track around the inside of the building.
I went into buydebug and planted 6 or 8 of each of the harvestables on the growing mats.
I used each of the fairies several times to drive the tractor and water, fertalise and harvest. No problems. Although harvesting the money trees seemed to continue showing the animation for a longer time than I had expected and felt that was a bit worrying.

She watered and fertalised with no problems. When she harvested all appeared good until she parked the tractor. She froze in place for a few seconds and then she and the tractor vanished. I found her back at home and had to buy a new tractor.
I put NRAAS mods in and tried again. Same result.
I sent her to consign the harvestables and fish in her inventory. There was a lot there.
I tried getting her to harvest with the tractor again and it seemed to work.
Here is another fairy harvesting again after I took all mods out of the game.
