How to Unlock Whack-A-Thresher

Complete Breeding Daisies

Borderlands 4 Mort Second Location

You need to complete the Breeding Daisies side mission first before unlocking Whack-A-Thresher.

Once unlocked, you can start the side mission by talking to Mort in his ranch, south of The Howl and west of The Launchpad.

Whack-A-Thresher Walkthrough

Slam Some Threshers

Once you've accepted the mission, Mort will ask you to slam threshers that pop out of the ground. To perform a ground slam, double jump and hold the Circle button (PlayStation) or B button (Xbox). Slam the threshers seven times to complete the mission.

To do this efficiently, hop on top of the water tank for a better view of the ranch. When a blue marker appears, immediately double jump and ground slam toward it. You can also glide for more responsive ground slams.
