Solutions To Common Ferris 400s Problems

Most of the Ferris 400s problems are mild and can be fixed easily. So, if you know a mower and its functioning and some basic skills, you can resolve these issues.
1. Operating Issue
Operating issues are quite common and can appear for various reasons.
If the fuel tank does not have the recommended amount of gasoline, it can make operating a tough task.
The old, dirty, or wrong type of oil can also be the culprit of operating issues.
If your mower doesn’t start or experiences intermittent electrical issues, it could be due to a dead or weak battery.
The starter solenoid engages the starter motor when you turn the key. It may be faulty if you hear a clicking sound when attempting to start the mower, but the engine doesn’t turn over.
Inspect the wiring harness for any visible damage, such as frayed or disconnected wires.
Solution
To fix the problem, check the Ferris 400s gasoline tank and ensure the oil is fresh and clean.

You must also ensure that the cooling fins, carburetor, air, and fuel filters are clean and working smoothly.
Check the battery voltage as well with a multimeter. If the voltage is low, recharge the battery or replace it if necessary.
Inspect the battery terminals for corrosion, looseness, or dirt.
Clean the terminals and tighten the connections to ensure a secure and reliable electrical connection.
You should also check the solenoid and consider replacing the starter solenoid if it has any trouble.
Make sure all connections are secure and free from corrosion. Repair or replace any damaged wiring as needed.
2. Bad Traction
Bad traction is another common issue of Ferris 400s mowers. Usually, bad traction produces when dust or residue gets clogged in blades or other compartments.
Owing to this issue, the belt of your mower may keep displacing.
Solution
To resolve this properly, clean the blades with the assistance of a wire brush.
Moreover, you should also ensure that the mower deck and blade spindle are dirt-free.
3. Brake Problems
Over time, the brake pads can wear down, reducing their effectiveness.
Damaged or defective blade calipers are one of the main reasons behind brake problems.
Faulty or damaged brake cables can also affect the brake system’s performance.

There can be many cutting issues, such as scalping grass, streaking, uneven cutting, or step cutting.
It can be frustrating and damage your lawn’s tidy and beautiful look. But you can fix them easily if you figure out the real culprit.
If blades are damaged, dull, dirty, or installed improperly, you can face the cutting issue.
Besides that, uneven mower deck, loose or twisted spindles of the mower, or clogged discharge chutes are other reasons for cutting issues.
The fast speed of the mower, wet grass, or uneven lawn can also play a key role in generating these problems.
Solution
To resolve this issue, you have to sharpen the blades as they can get dull owing to excessive use.
So, inspect the Ferris 400s deck and level it correctly. If problems still appear, then inflate the tires.

5. Mower Tough To Steer
Usually, Ferris 400s work well, but in some cases, it may become challenging to steer it.
As far as the causes are concerned, lack of lubrication is the main cause. In addition, inflated or imbalanced tires are also big contributors.
Another reason behind the difficulty in the steering is the incorrectly leveled deck.
Solution
If you are going through this issue, take a good quality steering oil and properly lubricate all the connectors.
Besides that, make sure that the steering wheel is positioned and centered accurately.
Inspect the tires of your Ferris 400s, and if they are deflated, inflate them. However, if they are damaged, then replace them.
Lastly, check the deck; if it is bending on one side, then balance it.
6. Blades Not Engaging
Blades not engaging is another prevalent issue that users complain about. There are a bunch of reasons that spark this issue.
One of the biggest causes is the clutch system. Firstly you need to learn how it works.
The main function of the PTO (power take-off) clutch is to separate the engine from the blades.
So, when the solenoid of the clutch becomes activated, it will operate the drive belt, which in return makes the blade rotate.
Hence, if any part of this clutch system is faulty, like the PTO clutch, clutch cable, solenoid, or PTO switch, is damaged, then the blades will not engage.
It is also worth mentioning here that damaged drive belts or pulleys are also some reasons for this problem.

If this issue lingers, it may damage the whole clutch system, and you must replace it. So, fix the problem without any delay.
It is also imperative to examine your Ferris 400s belt and pulley. And if they are worn out, then swap them.

When it comes to causes, a clogged deck assembly can cause a vibration issue.
Apart from that, unlevelled, broken blades or damaged bearings spindle of blades can also develop this alarming issue.
Another worth-mentioning cause of vibration is weight disruption inaccuracy or imbalance.
Solution
First, properly clean the deck assembly or underside area to solve this issue.
If you find any caked grass clippings, soil, or stones, then clean them.
If the issue stays even after cleaning, you must inspect the blades and their belt and bearing spindle.
You need to repair it if any of these compartments have faults. Additionally, if the damage is too much, then replace them.
You can consider investing in this blade if your mower blade is completely damaged. But before buying, ensure that it’s compatible with your model.
