A cultivator is an essential tool for your vegetable garden. Cultivators work like rototillers; the only difference is they are much smaller and can't tear through existing sod and plants. Keeping your garden tilled throughout the summer will increase moisture and oxygen availability to your plants, resulting in much healthier plants. Like rototillers, you must adjust cultivators to attain the proper tilling depth in your garden. To adjust a cultivator you only need a few tools.
Move the cultivator to a smooth surface with a well-lit area. Turn off the engine, and disconnect the spark plug. Grasp the spark plug wire cap to firmly pull it off of the spark plug.
Locate the tine guard located above the tines. Look for the two wing nuts on top of the tine guard. Grasp them with your fingers, and loosen by turning them counterclockwise.
Slide the wheel bracket assembly up for deeper penetration and down for shallower penetration. The wheel bracket assembly is located directly above the wheels of the cultivator.
Grasp the wing nuts with your fingers and tighten until they are hand tight. Reconnect the spark plug by pushing the spark plug wire cap back on the spark plug. Your cultivator is now ready for use again.
