The seed meter gearbox has a flexible rotatable drive shaft receiving portion and a gear receiving portion. The gearbox output is drivingly coupled to the seed meter for driving the seed meter. The flexible rotatable drive shaft receiving portion extends outwardly from the gear receiving portion for receiving the drive ferrule of the flexible rotatable drive shaft. The gearbox restrain extends outwardly from the seeding machine and engages the flexible rotatable drive shaft receiving portion. The gearbox restrain comprises two legs that are parallel to the gearbox drive axis. The flexible rotatable drive shaft receiving portion is sandwiched between the two legs to prevent rotation of the gearbox.
