Farming Simulator 17 was released on October 25, 2016.[9] It features the return of Fendt since its last debut in Farming Simulator 2009, and also Massey Ferguson, Challenger, and Valtra. For the first time in the base game, soybeans, sunflowers, and oilseed radishes are introduced as growable crops. In previous games, the player would have had to download a modification to add these crops. The crop growing mechanics have been altered, to allow different ways to increase crop yield. These include fertilizing the fields multiple times throughout the growth stages, plowing the field after a set amount of harvests, de-weeding crops, or using oilseed radish as a cover crop.[10] The missions system were also updated, allowing the player to do work for other in-game farmers. Other additions include drivable trains and an in-game radio. On November 14, 2017, a new expansion pack was released for all platforms. This added a new map, the growth of sugarcane and new vehicles and tools. This was called the platinum expansion pack and is free with the season pass which is also available for all platforms.
