How to fix your Garden Maid front-tine tiller when its engine leaks oil or gas

Oil leaks from a tiller engine can be caused by a leaking head gasket, sump gasket or oil drain plug. A loose or cracked fuel line can leak gas. A failed seal on the carburetor can also leak gas.

If the engine leaks oil, check the head gasket and replace that gasket if it leaks oil. Check the sump gasket if oil is leaking from the bottom of the engine and replace the sump gasket if it leaks. Tighten or replace the oil drain plug if it's leaking.

If the engine leaks gas, move the tiller to a well-ventilated area and check the fuel line. Reconnect the fuel line if it's loose and replace the fuel line if it's cracked. If the fuel line is okay, check the carburetor. Rebuild the carburetor with new seals and gaskets if the carburetor leaks gas. Sometimes, it's easier to replace the carburetor than to rebuild it.

Common repair parts for Garden Maid front-tine tillers

• Air filter. The tiller's air filter removes contaminants from air before it reaches the engine, to help reduce engine wear and improve efficiency.
• Carburetor. The carburetor mixes air with fuel in the proper proportion to produce a combustible gas. That gas/air mixture is pulled into the cylinder where the piston compresses it and the spark plug ignites it.
• Clevis pin. The clevis pin is a shear pin that couples the tines to the rotating tine shaft. The clevis pin is designed to shear off if the tines hit a fixed object during cultivation to prevent damage to the engine and other tiller components.
• Depth stake. The depth stake is a metal stake attached to the tiller near the tines. Raise or lower the depth stake to control the tilling depth.
