Start in free farming mode in Montana with $5 million.
2 Large Fields
2-4 Large Tractors
2 Large Harvesters with Headers
2 Semi Truks with Large Trailers
2 Large Plows (when I say large I mean the largest width)
2 Akpil Gerard Drill 3 Seeders (these cultivate and plant simultaneously saving time). Make sure and fill it with wheat.
2 Large Spreaders. Fill it with fertilizer.
2 large water tanks. Fill them with water.
Some equipment you’ll have to buy directly at the shop, some of the largest equipment cannot be delivered to your shed.
Position all equipment nearby the two fields, and start by hiring a worker to plow the fields, then cultivate/seed, then fertilize (doing this essentially doubles the yield so you only have to do each field one time), then water. If rain is in the forecast you can either accelerate time until it does rain and skip this step or go ahead and water.
Once all steps have been completed accelerate the clock to 600x until the wheat is golden brown, then use the harvesters (again with hired workers) to harvest the wheat. Collect the wheat with your trucks. Deliver to the barn. Once storage reaches 200,000 pounds the achievement will unlock.
What to do while passing the time in between plowing etc.? Collect the 100 sapphires. I made a guide with a map attached, -OR- if you open the computer and go to functionalities you can skip time and the work will proceed within seconds saving a great deal of time. if you use the skip time function after each hired worker, for instance setting both fields to plow, you can set the time to skip by about five hours and the plowing should be done almost instantaneously. Do this after each step to make things happen quickly.
Skip time about 4-5 weeks and you will notice the stock market will be very high for most items that you now have because you haven’t sold anything. Grab a trailer full of wheat or some other commodity that you have and sell it for the “Reasonable Farmer” achievement.
