A locking mechanism for an agricultural header includes a rod configured to extend laterally along the agricultural header and a cam coupled to the rod and configured to engage a respective arm of the agricultural header. The arm is configured to support a cutter bar assembly of the agricultural header, and the arm is configured to rotate relative to a frame of the agricultural header. The rod is configured to rotate in a first direction to a first orientation to engage the cam with the arm to block rotation of the arm relative to the frame, and the rod is configured to rotate in a second direction, opposite the first direction, to a second orientation to disengage the cam from the arm to enable rotation of the arm relative to the frame.

A work vehicle includes a first ground-engaging implement and a second ground-engaging implement connected to a chassis.

A lift arm is connected to the chassis and positioned between the first and second ground-engaging implements. The lift arm moves along a range of movement between a raised position and a lowered position. The lift arm is entirely positioned outside both of the first movement envelope and the second movement envelope within the entire range of movement between the raised position and the lowered position, such that the lift arm is permitted to move along the entire range of movement between the raised position and the lowered position without abutting the first movement envelope or the second movement envelope.
