ATV with ratcheting four wheel drive actuator

A vehicle comprising a shifter assembly for changing between a first drive configuration and a second drive configuration a of the vehicle, the shifter assembly comprising:

• a cam having a position indicator, the cam being rotatable about a first axis between first and second cam orientations such that the position indicator is moveable between first and second indicator positions, respectively;
• and
• a trigger assembly having a trigger lever and an engagement pin extending therefrom, the trigger lever being rotatable about the first axis such that the trigger lever is moveable between first and second trigger positions,
• wherein the cam defines an engagement lip displaced from the first axis,
• wherein the engagement pin is displaced from the first axis and is configured to engage with the engagement lip of the cam when rotation of the cam and trigger lever are synchronized, thereby enabling the trigger assembly to influence rotation of the cam, and
• wherein the first and second indicator positions are associated with the respective first and second drive configurations of the vehicle.

A method of mechanically shifting an all-terrain vehicle (ATV) between first and second drive configurations by using a trigger assembly of a shifter assembly to move a cam of the shifter assembly between respective first and second cam orientations, the method comprising:

• engaging the trigger assembly with the cam;
• moving a trigger lever of the trigger assembly from a first trigger position to a second trigger position while the trigger assembly remains engaged with the cam, thereby moving the cam from the first cam orientation to the second cam orientation;
• and
• disengaging the trigger assembly from the cam while retaining the cam at the second cam orientation.
