Mark the grassy area to be removed, using spray paint. Push a sod cutter to the area's edge.
Move the lever on the right-hand side to neutral. Push the choke in, and pull the start-cord. Pull the front handle back, and squeeze it together with the back handle. Move the lever to the scissors icon.
Release the throttle to give the sod cutter gas. The sod cutter will propel forward, cutting through the dirt as it goes. Allow the sod cutter to set the pace.
Turn corners slowly, maintaining the same cut width. Release the front handle to turn off the sod cutter. Use a flat-tipped shovel to cut the sod into 3-foot lengths. Roll the sod, and plant it in a new location as soon as possible.
Mark out the grass to be removed. Push a flat-tipped shovel's tip 2 to 4 inches into the soil.
Section out the area into 2-by-1-foot rectangles, using the shovel. Angle the shovel's tip underneath one of the rectangles. Push forward, and lift to separate the sod from the earth.
Set the sod rectangle aside, and remove a second rectangle. Continue until the entire area has been removed.
