Far Cry 5 - Fertilizing the Land Trophy Guide / Achievement Guide - Using a tractor, obliterate 5 enemies (Campaign only) [Bronze]

Go to the Outpost "Nolan's Fly Shop" in Faith's region. It's to the east of Hope County Jail, see location in video.
In that Outpost stands a Tractor. Enter it and then run over 5 enemies total. Be sure to put the game on easy difficulty and bring a few medkits so you can heal yourself when the enemies shoot at you.

You don't have to kill 5 enemies in one hit, it's 5 total (kill 5 x 1 single enemy).

If you're already liberated this outpost you can reset it in the pause menu by clicking on "Outpost Master", but you must have liberated all of the Outposts for this to work.
