7 Most Common Ferris 400S Problems and Solutions
Problem 1: Engine Starting Issues
The frustration of pulling the starter cord or turning the key only to find the engine of your Ferris 400S refusing to start can be all too familiar. Engine starting issues can arise due to several potential causes, including problems with the ignition system, battery, or fuel system.
A. Possible Causes:
- Faulty Ignition: The ignition system is responsible for generating the spark that ignites the fuel-air mixture in the engine. If any part of the ignition system, such as the spark plug wire or ignition coil, is faulty or damaged, it can lead to starting problems.
- Battery Problems: The battery supplies the initial electrical power to crank the engine. A weak or dead battery may not provide enough energy to start the engine or may cause slow cranking.
- Fuel System Issues: Problems with the fuel system, such as clogged fuel filters or a malfunctioning fuel pump, can result in insufficient fuel reaching the engine, hindering the starting process.
B. Troubleshooting Steps:
To diagnose and resolve engine starting issues on your Ferris 400S, follow these troubleshooting steps:
- Checking Spark Plugs: Spark plugs play a crucial role in initiating combustion in the engine. Inspect the spark plugs and their wires for signs of wear or damage, such as carbon buildup, corrosion, or cracks. If any issues are detected, replace the spark plugs and wires with the manufacturer-recommended ones.
- Testing the Battery: Use a multimeter to check the voltage of the battery. A fully charged battery should read around 12.6 volts. If the voltage is significantly lower, recharge the battery and test it again. If the battery does not hold a charge or fails the test, consider replacing it with a new one.
- Inspecting Fuel Lines and Filters: Carefully examine the fuel lines for any kinks, leaks, or blockages. Replace any damaged or clogged fuel lines. Next, check the fuel filter for debris or contaminants. If the fuel filter appears dirty, replace it with a new one. Additionally, ensure that the fuel tank has enough fuel to support the starting process.
By following these troubleshooting steps, you can narrow down the potential causes of engine starting issues on your Ferris 400S. Identifying and addressing the problem promptly will ensure that your mower starts reliably and performs at its best, allowing you to get back to efficiently mowing your lawn or tackling commercial landscaping tasks.

Problem 2: Uneven Cutting
Uneven cutting is a common problem that can lead to an unsightly lawn appearance and frustration for the operator. There are several potential causes for this issue, including a malfunctioning mower deck, worn-out blades, and improper deck adjustment.
Causes:
- Malfunctioning Mower Deck: The mower deck houses the cutting blades and is responsible for ensuring an even cut across the entire mowing width. If the mower deck is damaged, misaligned, or experiencing mechanical issues, it can lead to uneven cutting.
- Worn Blades: Over time, cutting blades can become dull or bent due to regular use and encounters with debris. Dull blades tear the grass rather than providing a clean cut, resulting in an uneven appearance.
- Improper Deck Adjustment: The height and level of the mower deck are crucial factors for achieving even cutting. If the deck is set at an incorrect height or is not level, certain areas of the lawn may be cut too short or too tall.
Troubleshooting Steps:
To troubleshoot and resolve uneven cutting on your Ferris 400S, follow these steps:
Leveling the Mower Deck:
- Park the mower on a flat and level surface, such as a concrete driveway or garage floor.
- Lower the mower deck to its lowest cutting height.
- Measure the distance from the blade tips to the ground on each side of the deck. Ensure that the measurements are equal on both sides.
- Adjust the deck lift links or turnbuckles as necessary to level the deck. Refer to the operator’s manual for specific instructions on deck leveling.
Sharpening/Replacing Blades:
- Disconnect the spark plug wire to ensure the engine cannot start while working on the blades.
- Remove the cutting blades from the mower deck. Follow the safety guidelines and instructions provided in the operator’s manual.
- Inspect the blades for signs of wear, damage, or bending. If the blades are severely worn or bent, replace them with new ones.
- Sharpen the blades using a file or bench grinder if they are still in good condition. Follow the manufacturer’s recommendations for sharpening angles and techniques.
- Reinstall the blades back onto the mower deck, ensuring they are correctly oriented and securely fastened.
Adjusting Deck Height Properly:
- Check the operator’s manual for the recommended cutting height settings for your desired grass length.
- Adjust the deck height according to the manual’s instructions, using the provided levers or adjustments on the mower.
- Make sure the deck height is uniform on both sides to ensure an even cut.
Regularly inspecting and maintaining your Ferris 400S mower’s cutting system, including the mower deck and blades, is essential to achieving a well-groomed lawn. By following these troubleshooting steps and properly maintaining the cutting components, you can enjoy consistent and uniform cutting performance throughout your mowing tasks.
