How to fix a self propelled lawn mower

1. Self-propelled feature not working

It is very common for self-propelled lawn mowers to have problems with the actual self propel feature. If this is the case, find the cable running down from the handlebar and straight to the transmission box. Check if this has been damaged due to mechanical wear and tear. Once you see signs of rips and tears on the said cable, then you will have to replace it with a new one so that the transmission box can once again drive the wheels correctly.

2. Transmission is unnecessarily clogged up 

To troubleshoot the transmission, start by removing the cover and checking for dirt, debris, packed grass clippings, wood chips, and other random materials which may be the cause of the transmission clogging up. Another thing that you have to check is the lubrication of the transmission. The transmission must be thoroughly lubricated so that it operates correctly. The lubrication of the transmission is a commonly overlooked maintenance task that can easily lead to the failure of the entire self-propelled system.

3. Gears and wheels are not turning

The gears and wheels may not be turning properly. If that is the case, then you have to check whether there are any materials stuck in the gears or wheels. It is also important to check whether or not the wheels and gears are sufficiently lubricated, especially the drive wheels. Also, check if the wheels look already worn out as that may signal you that you already need to find a replacement for it.

4. Lawn mower blade not turning

There are cases when the lawn mower’s blade itself is not turning. To troubleshoot this concern, start by turning the equipment over on its side and then check for any material that may be obstructing the blade from correctly turning, seeing to it that the blade is really sharp and correctly attached to its proper torque ratings. Loose blades wobble easily during lawn mowing which can significantly affect the performance of your lawn mower. It is also dangerous since the blades may become unattached and fly off, causing injuries to people around.

5. Engine not properly starting

There will come a time when the engine itself is not starting. For this issue, troubleshoot by checking the battery, ensuring that it has full voltage, as well as the starter for its correct voltage. You have to do away with drained batteries or burned-out spark plugs as these are the common causes for the self-propelled lawn mower engineer not starting. In case that the problem is sputtering, dying out, or surging, then the problem lies with the fuel system so check it out.

6. Oil fuel

With self-propelled machines running on gasoline, we always have to pay attention to the problem of changing oil for the machine. Make sure that the old oil is completely removed when changing the oil before adding new oil. Machines that have not been used for a long time, check whether the fuel tank has a bad smell or not. Remove all fuel, change the filter, and refill with new fuel. Note that with a 4-cylinder machine we do not need to mix oil with gas.

7. Machine power cord

With corded electric lawn mowers, this is one of the most important parts. Before starting the machine, check the cable and socket carefully to ensure the safety of the user. Always keep the air filter and carburetor to keep the engine in top condition.

The transmission is one of the main parts that make the self-propelled lawn mower able to operate smoothly. So no matter what the problem with the actuator we need to grasp it well.

4. Are there ways to test traction control cables?

To see if the tensile cable is stable, we can use long-range temperature and strain measurements along with a given optical fiber. We also have a new optical sensor based on pre-excited Brillouin scattering. The resulting optical effect will be like a sensor element that checks the cable without having to deal with the cable through any process.
