Causes of a Non-Running Ferris Zero-Turn Mower

Without gasoline, your lawn mower will lose power, operate poorly, and eventually stop.

If the carburetor is blocked, the fuel line is plugged, the fuel filter is clogged, the fuel pump fails, or the gas cap is broken, your Ferris zero turn lawn mower will not obtain gas. Running old gas, which contains deposits limiting fuel and damaging fuel components, is a common cause of these breakdowns.

Make sure you’re taking all the necessary safety measures before working on the gasoline system, as outlined in the Ferris owner’s handbook. Working in a well-ventilated environment, after allowing the mower to cool, and while wearing protective gear are all essential.

Fixing Fuel Delivery Problems on a Ferris Lawnmower

A Ferris Lawnmower With Old Gas

Modern gasoline contains ethanol, which has a hygroscopic property and draws water from the atmosphere. Gummy deposits caused by this ethanol and water combination will eventually clog gasoline lines.

The fuel components are also susceptible to corrosion and early failure due to this solution. These gasoline limits and broken fuel components will leave your mower stranded.

Here you may learn more about what fuel works best in your Ferris lawn mower. Moreover, I provide advice on how to store and stabilize your gasoline, as well as details about the impact of ethanol on your fuel.

Moisture and sediment in the fuel system can corrode and block the fuel components of your Ferris lawn mower if it uses diesel fuel.

SOLUTION: If you want to save the old gas for later, you can drain your tank with a siphon pump. Plastics deteriorate rapidly and leak fuel, so use only a container made for gasoline.

Prepare to transport the gasoline to a designated recycling facility.

Do not forget to apply a gasoline stabilizer when refueling. My lawn mower’s motor has been treated with Sea Foam. Benefits include fuel stabilization for up to two years and fuel system cleansing.

Fuel Filter Clogged on a Ferris Lawnmower

A gasoline filter in a Ferris is used to remove debris and dirt from the fuel supply before it may harm the fuel system or the engine. The gasoline filter should be changed once a year when you service your Ferris lawn mower.

If you don’t change your filter on a regular basis, dirt and silt will build up inside of it, blocking the flow of gasoline.

SOLUTION: When you see that your gasoline filter is clogged, you should change it out. When changing the filter, make sure to follow the arrow on the plastic housing. In order to ensure proper fuel flow, the replacement filter’s arrow must be fitted facing the correct direction.

Lawnmower with Ferris Fuel Lines That Are Always Clogged

When you use old fuel, gummy deposits build on the inside of the fuel tank and the fuel lines. If the fuel line to your Ferris mower is clogged, you won’t be able to use it.

The only way to determine which part of a gasoline line has become clogged is to examine the entire hose.

SOLUTION: The fuel shut-off valve is placed at the base of your fuel tank and is used to begin and end gasoline flow. To clamp the line and halt the flow, hose pinch-off pliers can also be used.

Start and stop the gasoline flow via the pipe to check for leaks at each segment.

When you locate the blocked area of the hose, you should take it off the mower. Carburetor cleaning can be sprayed into the hose to help break up the blockage. Use a can of compressed air to blow the line to pieces. It will take many tries to clear the blockage and restore normal flow.

It is time to replace your gasoline line if you are unable to unclog it or if it is dry and cracked.

A faulty fuel pump in a Ferris lawnmower.

When the carburetor is mounted above the fuel tank, as it often is on a Ferris mower, a fuel pump is required to provide the engine with gas. Fuel must be pumped up to the carburetor, which means the pump must operate against gravity.

A vacuum fuel pump is commonly used in lawn mowers. The gasoline is pumped using pressure created by the engine’s crankcase.

The gasoline pump must be replaced if it develops cracks or stops functioning properly. There should be no visible signs of gasoline leaking or cracks, therefore you’ll need to perform some troubleshooting to see if the fuel pump is the source of the problem.

SOLUTION: Make that the fuel pump is receiving fuel before inspecting the fuel pump itself. If you have already examined your gasoline filter and lines for obstructions, you may skip this step.

The gasoline must be cut off immediately. First, disconnect the gasoline line from the fuel pump’s input port. Restart the fuel flow by putting the line in a container that is lower than the fuel tank.

You know you have flow if fuel is entering the storage tank from the line. If not, then the gasoline lines or fuel filter may be clogged, and you’ll need to clear it out.

When you are sure fuel is reaching the pump, reconnect the fuel line to the intake. The gasoline line should be disconnected from the carburetor and stored in a safe location.

Start the gasoline flow and the mower to make sure the pump is operating properly. The gasoline line should be releasing a continuous or pulsing stream of fuel. If you don’t, your fuel pump will soon die.

Get a fuel pressure measurement from the pressure pipe of an injection fuel pump. The recommended fuel pressure is specified in your user handbook. If the fuel pressures are too low, you should get a new fuel pump.

Faulty Ferris Lawnmower Caused by a Filthy Carburetor

A carburetor controls the ratio of air to fuel that is injected into the engine to generate combustion. If the carburetor is filthy, it prevents fuel from reaching the fuel jet, which prevents the Ferris mower from starting.

SOLUTION: The first step in cleaning a carburetor is figuring out if you need to take it apart. Watch the gasoline level in the carburetor to make sure it is getting enough fuel. If you aren’t, perhaps there’s a blockage in the gas tank’s gasoline line, filter, or pump.

After that, take off the actual air filter from its housing. To clean the carburetor, spray the intake with cleaner.

See if your car will start by trying to start its engine. Remove the carburetor from your lawnmower and disassemble it to clean it if it starts but then dies. To learn how to take apart and clean the carburetor on a Ferris mower, read this article.

A Ferris Lawnmower with a Defective Fuel Cap

A Ferris fuel cap is perforated to enable air to flow in and out. Blockage of the vent stops air from escaping. When this occurs, there is a complete vacuum in the tank, and no gasoline can escape.

If you start your mower with and without the fuel cap, you might be able to tell if the fuel cap is blocked.

A blocked fuel cap may be the cause of an engine that starts and runs OK when the fuel cap is removed but dies or runs slowly when the lid is reinstalled.

SOLUTION: In order to clear the vent, you might try cleaning the fuel cap. A new Ferris fuel cap should be purchased if this fails to work.
