Draining oil when it’s cold is not ideal as a little may get stuck.
Drain the gas:
Unscrewing the fuel hose clamp to drain the fuel should be your next step. Another method involves tracing the fuel hose route from the base of the gas tank to the engine.
Loosen the clamp, remove the hose and drain the fuel in a container.
Find the throttle linkage:
This component is under the machine’s carburetor. You will find a cable connecting and holding the throttle in position, unbolt the screw, remove the screw and set it aside.
Unscrew unnecessary bolts and nuts:
A lawnmower is a yard maintenance tool made with quality materials and offers exceptional qualities. Ensure you unscrew unnecessary bolts and nuts, attaching any component to the machine seat and body parts.

Unscrew the bolts holding the flywheel in position until the claws reach the bottom end of the crankshaft for easy removal.
Lawnmowers come in different shapes, designs, and blade in various sizes. You will find the blade attached to the motor. Use the screwdriver to unbolt it and set it aside.
The component delivering torque to the mower wheels for easy movement is your driveshaft. Unscrew the driveshaft and bring the aluminum tube closer.
Introduce the long driveshaft and weld the hollow aluminum tube to the top of the motor.
Please pick up the propeller and hold it against the drive shaft bottom before matching up the gears. It is advisable to ensure the turning propeller turns the drive shaft for efficient results.
Ensure the propeller is safe before bolting or welding the component to the aluminum pole, depending on your propeller type.
Make sure you weld the propeller properly and fit seamlessly for efficient operations.
Step 3: Create your tiller
If you’re a fan of small boats or enjoy riding along the river on a beautiful morning, it’s time to live the life of your dreams.
Now that you can weld the propeller to the aluminum pole, turn the pole from the bottom up around 50 degrees. It’s time to weld the aluminum tube’s bottom to the motor facing upwards.
You just created your tiller.
