Chill Cave Easter Egg
The easter egg is a long walk from the start point on the map, so you will need a vehicle. It does not matter which vehicle (tractor, DLC gator, or truck).
Here are the steps.
1: Hop into your vehicle and head for the middle of the map.
2: Around field 16 (I think?), you will see a wooden windmill on a cliff, and a medium bush around a shaded area.
3: You can either hop out of the truck by the bush and walk into the secret area, or drive up to the windmill, go into the open door, and head down the trapdoor (both ways lead to the same area).
4: Go take a rest. You earned it.
Infinite Money
You have to edit both careerSavegame.xml and farms.xml, and ensure that the money matches in both files. farms.xml will have a number followed by a period and several 0's. Just change everything to the left of the decimal to match what you've changed in the career file.
First go to your savegame, for example first save slot:
documents / mygames / FarmingSimulator19 / savegame1 / careerSavegame.xml
and change this line near the end
[money]500000[/money]
Then go to;
documents / mygames / FarmingSimulator19 / savegame1 / farms.xml
and change this line near the end
money="500000?
to whatever you like - have fun!
Playthrough Strategy Tips
Free water. Water from your pump on your farm (any pump on map actually) costs you money. Free water can be obtained by backing the water tank trailer into the river and loading it while submerged. The sandy "beaches" next to natural water formations is the best and safest spot.
Starting Tractors. You have more tractors than you really need. Keep your biggest tractor and then the one with the lowest hours. This will give you two tractors to start with.
Missions. Many feel that missions pay to much for to little effort and shun them. That is your choice in how you want to play YOUR game. Missions are a good (prob best) way to earn cash. In FS19 all you have to do is show up and provide the labor (time). As the equipment is provided to complete the mission.
Do not freak out at high equipment maintenance. An old tractor that costs 5 times as much to maintain as a new one is still very much profitable to run. Don't get rid of equipment just because it isn't shiny and new, only sell it if you genuinely don't need it and have something better.
Working your own fields is a pretty slow way to make money in single player. If you are looking to expand quickly, look to other options, such as:
Missions (tons of easy money quickly)
Solar power / beehives (slow money, but zero effort, making for short days)
Greenhouses (IMHO, a nice compromise between fields and solar, you still have to do a bit of work, but it's not nearly as long and grinding as fields)
Maintenance is paid daily so will be more of an issue if you like to speed up time, if you like to play fast then it is recommended you place some passive incomes to offset the costs, Greenhouses are the best value by far, even if only supplied with water.
Don't smoke near the slurry tank.
Icons beside each type of crop will show if the price of it is higher or lower than normal. Every now and then a special demand will go up at a certain buyer and you can make a huge amount of money if you happen to have a large stockpile of said crop.
You can buy a fertilizer spreader or a sprayer and fertilize your crops after they've been planted to double your yield upon harvest.
The goal of the game is to earn money, buy better equipment, fields, and harvest more advanced crops.
