How to Make a Go Kart From a Lawnmower

Locate a metal frame that can serve as the structure of your go-kart. It should be able to hold both the vertical shaft engine from a push or riding lawnmower and a lawnmower gearbox. If the go-kart gets into an accident, both of these components will be well protected by the frame.

Purchase a new or used lawnmower. Make sure the engine is in good condition and has no damage. Verify that the engine starts up when you pull the cord out. If the engine and cord work flawlessly, then you're in good shape.

Loosen the screws on each lawnmower blade with either a screwdriver or wrench, depending on the lawnmower type. Once the screws are loosened, disconnect the lawnmower blades from the drive shaft on the lower section of the mower deck.

Disconnect the lawnmower engine from the mower deck by loosening the bolts holding them with either the screwdriver or wrench, depending on the lawnmower type. Unplug any wires connected to the engine and lawnmower deck. Then remove the engine.

Use welding tools to fabricate a metal plate that will protect the engine and transmission system you are building. Since every component will vary in size, make sure the metal plate will cover them completely to avoid external damage. The metal plate will also keep your go-kart stable and balanced while driving it.

Add a third wheel to your go-kart on the back axle of the exhaust system. Make sure that the engine's metal plate is connected to this wheel at all times as it will be responsible for making your go-kart drive forward.

Create a bracket on the stainless steel frame to support the mounted engine on its side at a 90-degree angle, which automatically positions the drive shaft for proper attachment of the cogs and chain. Connect the chain to the axle's cog.

Connect the gas tube to the carburetor and reconnect all the electrical wiring that was originally part of the lawnmower engine.

Add gas to your newly built go-kart. Pull the cord and you're off.
