Abstract

A harvester includes a main frame, first side frame, and a second side frame. The first and second side frames are rotatable about the main frame between a deployed position and a stowed position. A first crop divider is rotatable with respect to the first side frame to change an angle between the first crop divider and the ground. A first biasing member biases the first crop divider into the raised position. A second crop divider is rotatable with respect to the second side frame to change an angle between the second crop divider and the ground. A second biasing member biases the second crop divider into the raised position. During movement of the first and second side frames into the stowed position, the first and second crop dividers are moved into the lowered position against the biasing force of the respective biasing member.
