Do you want to know why Grasshopper cranks but won’t start? The most probable cause can be lousy fuel because when the fuel sits for a few months, it can’t flow in the correct proportion. To learn more, we will discuss this topic in detail.

Well, In such a case, the gas won’t flow with proper pressure and gum up the carburetor with the fuel line. When your Grasshopper machine isn’t used during the off-season, this problem arises more.

Now, we discuss major and minor problems with their solutions. So continue your scrolling and stay with us.

Grasshopper Cranks But won’t Start & Solution

Now, we focus on some specific and necessary troubleshooting with their proper solution. Hopefully, if you follow the instructions correctly, you can overcome this starting problem. Let’s check them in detail.

Reasons For Not Starting GrasshopperSolutions
Not enough sparkChange ignition coil.
Slow rotationInstall a new starter.
Safety switch problemCheck connections & all safety switches.
No fuel or low fuelUse standard fuel.
Not engaging bladesCheck switch & clutch, blown fuse, battery power, and loose electrical connection.
Weak flywheel magnetsPut on a new flywheel.
No airflow pass into combustion chamberCheck the valves & reform the gas.

After seeing this table, we get an overview of the problem of Grasshopper mower cranks but wont start. In that case, we need to know why these problems happen and how we can recover quickly.

Not Enough Spark

The problem arises when the spark plug cracks and a gap appears between the ignition coil and the sparking system. In that case, the Grasshopper lawn mower will not start.

The solution is to look into the ceramic insulator and check the ignition coil. But remember that there is a slight risk to observing the ignition coil power and having a chance to feel the coil power face to face.

You can also troubleshoot this by ensuring the right spark plug gap and good condition spark plug.

Slow Rotation

When the electrical battery collapses and won’t make enough rotation speed, then the Grasshopper mower may not be starting. Some engines require up to 250 RPM, according to your engine requirement, and need exact rotation speed to keep the mower running continuously. And here, the battery starter works behind this.

So, in this case, you should install a new starter for a better service. After checking, when you feel the rotation speed wouldn’t be good enough, you can clean it and check. But it’s a wise decision to install a new starter rather than using the previous starter.

You can also check out the reasons your lawn mower won’t start after tilting, along with effective fixes.

Safety Switch Problem

Sometimes, when any of the safety switches goes bad or does not work properly, it can make the mower crank but won’t start properly.

In that case, check all the safety switches and their connections. Mostly you will find the safety switches under the mower seat.

No Fuel or Low Fuel

The fuel ending is a common problem, which can happen when the Grasshopper sits in the off-season; when the fuel ends and has no existence in the reserve system. And in this case, the Grasshopper mower will crank but won’t start.

In that case, you need to fill your oil tank with standard fuel. That will help you keep your engine efficiency stable and protect all types of harmful elements for a long time.

Not Engaging Blades

It’s one of the common Grasshopper mower electrical problems. When the blades are not appropriately engaged, the sparks won’t generate as much as needed, making a barrier to starting the Grasshopper engine.

So, you should check the switch & clutch, blown fuse, battery power, and loose electrical connection. If you see any fault, you should clean and install it properly. Hopefully, you get released from this problem.

Weak Flywheel Magnets

The weak flywheel magnets can’t generate the sparks properly, and there can be a chance of falling down the sparking system. As a result, the Grasshopper engines won’t get enough sparks and energy to start.

You should install a new flywheel magnet for better service. You can clean the magnet flywheel and reinstall it, but it may not get good results. So replacing it with a new magnet flywheel will be the wise decision.

No Airflow Pass Into Combustion Chamber

There is gumming up the carburetor and fuel line for the harmful gas. In that case, there is not possible to airflow into the engine’s combustion chamber. When this happens, the Grasshopper can’t generate a spark to start its engine.

The solution is to check the valve and reform the gas. You also need to clean the fuel line and carburetor so that the airflow becomes a great point. Hopefully, it’s good enough to recover this problem.

Frequently Asked Questions (FAQs)

How Can You Jump Start A Grasshopper Lawn Mower?

Connecting the negative charge with a fully charged battery would be best to jump-start a Grasshopper Lawn Mower. The other parts also need to join the black cable to the excellent chassis ground of the tractor.

Why Riding Mower Clicks When You Try To Start It?

This type of clicking sound can be the only reason of the starter solenoid. The safety switch and key switch are responsible for energizing the solenoid. When the solenoid is getting energized, it connects to the battery starter motor, and thus such a clicking sound comes.

Why Would My Grasshopper Mower Turn Over But Not Start?

The leading cause can be harmful gas. When the Grasshopper sits for a long time and won’t use, the gas can be damaged and gum up the carburetor with the fuel line. So, it’s the leading cause of not starting the Grasshopper.

Final Verdicts

Hopefully, you get a clear concept of the Grasshopper cranks but won’t start with their proper solution. Now, it’s easy to identify the problems and take appropriate steps to solve them quickly.

The main problem is not generating the right sparks in the combustion chamber and lousy gas. If you have a conscious mind on these factors, you can take the necessary steps timely by following our suggestions.

There is no option to reuse the flywheel magnet and starter. In that case, you should replace it with a new starter or flywheel magnet. Otherwise, it would have a destructive impact on your Grasshopper engines.

If you have any arguments, you can reread the content carefully or can get help from a Grasshopper engine expert.
