Engine won’t start
If you’re experiencing difficulty starting the engine of your Cub Cadet Src 621, there are a few potential causes to consider. The first thing to check is the fuel level.

Inspect the blade for any signs of wear or damage, such as nicks or cracks. If the blade is dull or damaged, it should be sharpened or replaced to ensure a clean and even cut. Another factor to consider is the cutting height adjustment. Make sure the cutting height is set correctly for the desired length of grass. Adjust the cutting height as needed to achieve a consistent cut across your lawn.
Self-propel feature not working
If the self-propel feature of your Cub Cadet Src 621 is not working properly, there are a few possible solutions. First, check the drive belt to ensure it is not worn or damaged. A worn or damaged drive belt can prevent the self-propel feature from functioning correctly. If the drive belt needs to be replaced, refer to the user manual for instructions on how to do so. Additionally, inspect the wheels for any debris or obstructions that may be hindering their movement. Clean the wheels and remove any obstacles to allow for smooth operation of the self-propel feature.

Troubleshooting Steps For Engine Won’T Start
If you’re experiencing problems with your Cub Cadet SRC 621 not starting, don’t worry. There are several steps you can take to troubleshoot the issue and get your engine up and running again. In this section, we’ll walk you through the key troubleshooting steps to help you identify and resolve the problem.
Check the fuel level
One of the first things to check when your engine won’t start is the fuel level. Ensure that there is enough fuel in the tank to power the engine. If the fuel level is low, simply add more fuel and try starting the engine again. Remember to use fresh fuel as stale or contaminated fuel can also cause starting issues. If adding fuel doesn’t solve the problem, move on to the next troubleshooting step.
Inspect the spark plug
The spark plug plays a crucial role in the ignition process. A faulty spark plug can prevent the engine from starting. Remove the spark plug and inspect it for any signs of damage or wear. If the electrode is worn down or covered in deposits, it’s time to replace the spark plug. Follow the manufacturer’s recommendations for the correct spark plug type and gap setting. Installing a new spark plug may resolve the starting issue. If not, proceed to the next troubleshooting step.
Examine the carburetor
The carburetor is responsible for mixing air and fuel in the correct proportions for combustion. Over time, the carburetor can become clogged or damaged, leading to starting problems. Inspect the carburetor for any signs of blockages or damage. Clean the carburetor thoroughly using a carburetor cleaner spray, following the manufacturer’s instructions. If the carburetor is severely damaged, it may need to be replaced. Once you’ve cleaned or replaced the carburetor, attempt to start the engine again.
Test the ignition coil
The ignition coil is an essential component that generates the spark needed to ignite the fuel mixture. A faulty ignition coil can cause starting issues. Use a multimeter to test the ignition coil for proper functioning. Follow the manufacturer’s instructions and compare the readings to the specified ranges. If the ignition coil is faulty, it will need to be replaced. Installing a new ignition coil can often resolve the engine starting problem.
Verify the engine compression
Engine compression refers to the pressure that is created inside the cylinders during the combustion process. Low compression can result in hard starting or a complete engine failure. Use a compression tester to measure the compression of each cylinder. Compare the readings to the manufacturer’s specifications. If the engine compression is below the recommended range, it may indicate a problem with the piston rings, valves, or head gasket. In such cases, professional assistance may be required to diagnose and repair the issue.
By following these troubleshooting steps, you can effectively diagnose and resolve the engine starting problems with your Cub Cadet SRC 621. Remember to always take proper safety precautions and refer to the manufacturer’s guidelines throughout the troubleshooting process. Now you can get back to enjoying a smooth and reliable mowing experience with your Cub Cadet lawn mower.
Troubleshooting Steps For Mower Doesn’T Cut Evenly
When it comes to maintaining a well-manicured lawn, a lawnmower that doesn’t cut evenly can be a frustrating problem to deal with. Thankfully, there are several troubleshooting steps you can take to fix this issue and ensure a flawless cutting experience with your Cub Cadet Src 621 mower. In this article, we will walk you through some simple yet effective troubleshooting steps that will help you get your mower cutting evenly again.
Check the blade condition
The first step in troubleshooting uneven cutting with your Cub Cadet Src 621 mower is to check the condition of the blade. Over time, the blade can become dull or damaged, resulting in an uneven cut. Inspect the blade for any signs of wear or damage, such as nicks, cracks, or a dull cutting edge. If you notice any issues, it’s time to replace the blade with a new one.
Adjust the cutting height
In addition to a sharp blade, the cutting height of your mower also plays a crucial role in achieving an even cut. To troubleshoot uneven cutting, check the cutting height setting on your Cub Cadet Src 621 mower. Make sure it is set to the desired height for your lawn. Adjust the cutting height as needed, keeping in mind that cutting too low can scalp the grass, while cutting too high can result in an uneven appearance.
Clean the mower deck
A dirty or clogged mower deck can also contribute to uneven cutting. Grass clippings, debris, and buildup can hinder the blades’ ability to cut evenly. To troubleshoot this problem, first, ensure the mower is turned off and the spark plug wire is disconnected for safety. Then, thoroughly clean the mower deck, removing any accumulated dirt, grass clippings, or debris. Pay extra attention to the areas around the blades to ensure they are clean and able to rotate freely.
Inspect the drive belt
The drive belt is responsible for transferring power from the engine to the cutting blades. A loose or worn drive belt can cause uneven cutting. To troubleshoot this issue, visually inspect the drive belt for any signs of wear, cracking, or stretching. If you notice any issues, replace the drive belt with a new one to ensure smooth and even cutting.
Ensure proper tire pressure
Uneven tire pressure can affect the mower’s stability and cutting performance. To troubleshoot uneven cutting, check the tire pressure of your Cub Cadet Src 621 mower. Ensure that the tires are properly inflated to the recommended pressure specified in the user manual or on the tire itself. Use a tire pressure gauge to accurately measure and adjust the tire pressure as needed.
By following these troubleshooting steps, you can address the common causes of uneven cutting with your Cub Cadet Src 621 mower. Remember to always prioritize safety when working on your mower and consult the user manual or seek professional assistance if needed. With proper maintenance and troubleshooting, you’ll be able to enjoy a beautiful and evenly cut lawn all year round.
