Unlimited Money
To get all the money you want on a previous saved game do this. Ok, this involves editing a game file. Go to where your game is stored on your Hard Drive and go into the John Deere: American Farmer file and find the file called "Data" then go into the file called "Games" all the files of your saved games should be in there. Find the name of the save you wish to edit. Right click on it and edit it in notepad. On the second line there should be a line there devoted to amount of money in your save, there should be the amount of money you have on that line, change it however you see fit :)
