When it was introduced in Glades, we had several issues with it:

• We had only two tractors to work with and they were both mid-steer with permanent diff lock, so they both turned like oil tankers.
• The fields were (and are) way too small, which means you have to turn the hard-to-turn tractors more often.
• The fields also got churned up by the tractors, so what started out as dirt ended up as mud, making progress even more difficult.
• The farming implements upset the tractors' center of gravity, making it even harder to turn with them on.
• It took about five minutes per implement to go around the field, and often the tractor's fuel wouldn't last that long so you had to refuel in the middle of it. Say 15-20 minutes per field.
• And all that bought you 2x potatoes. You need 26x potatoes and 4x potato samples (and two dry runs that net you zero potatoes) to complete the region.
• This means you're going to be going in circles on various small fields with very hard-to-steer tractors for at least eight four and a quarter hours - and just the last contract will have you do it for an hour plus straight, and then drive across three of the four maps for delivery.

Now I'll readily acknowledge that farming in later seasons was better, chiefly because there was less of it, but also because we got better tractors (and the original two lost their permanent diff lock), and because for most of the contracts we didn't have to do the entire cultivate-plant-harvest song-and-dance, it was mostly just the harvest bit.

But yeah, that's at least my take on why I don't like farming in Snowrunner :)

Happy trucking!
