Abstract: A shift interlock mechanism for automatically shifting a sod cutter into a low gear when a cutting blade is lowered into the ground and automatically raising the cutting blade when the sod cutter is shifted into a high gear. The mechanism may include a cutting blade lever. The cutting blade lever may include a cam member which engages the shift lever creating cam action when the cutting blade handle is raised to the up position. When the cutting blade lever is moved to lower the cutting blade, the cam member moves the shift lever into a low gear. When the cutting blade handle is in the up position and the cutting blade has been lowered, the shift lever will oppose the cam member and create an opposite cam action, thereby raising the blade, when the shifter is moved into a high gear.
