We will now discuss the Ferris IS2100Z mower problems, their reasons, and their symptoms. The potential causes we’ve identified so far are in the table. So, let’s get this conversation going.

Machine Won’t Start, Or Even If Started, Stops Suddenly

There are several reasons why the Ferris IS2100Z may not start. It’s also possible that the battery isn’t fully charged. Another possibility is that the gasoline line or spark plugs are malfunctioning. If the mower suddenly stops, the common reason is that the mower has run out of gas and the spark plug is not working correctly. If the mower’s engine is not getting enough spark, it will not be able to run.

Solution: First, you should check the oil level. Oil should be topped off to the full mark on the dipstick if the engine needs it. Next, check the gasoline level. If the tank is empty, add gasoline until it reaches the mark. If the issue persists, check the carburetor. Sometimes, the carburetor needs to be cleaned or replaced.

You must check the mower’s blade to resolve the sudden stop issue. The mower may abruptly halt if the blade is dull or broken. Changing the blade if it’s broken.

The Engine Starts Hard But Run Poorly

One of the most common issues owners of this mower face is that the engine starts hard but runs so poorly. These issues can occur due to dirty or clogged air filters, fuel mixture being too rich, etc.

Solution: In such cases, you have to clean the air filter. If this is not the case, then check the carburetor. You may need to replace it to solve the issue. To do that, go to your nearest dealer. If this is not the case, check the power supply, if you find it sparked, then change that.

The Battery Won’t Charge Or Mower Does Not Engage

There are various reasons why a Ferris IS2100Z battery may not charge or have charging issues. Most often, the battery isn’t getting enough juice to charge the mower. If the terminals of the battery are not working or the battery is damaged, the battery won’t work properly. If the alternator is defective, it won’t level up the battery’s charge.

Solution: If your Ferris IS2100Z battery won’t charge, inspect the terminal for damage. Before checking the terminal make sure the battery is properly installed and connected. If everything looks good there, check the voltage of the battery. If it’s low, you may need to replace it. Finally, if the mower does not engage, make sure that the safety switch is in the “On” position.

Moreover, even if you’ve been using the same batteries for a while, they may no longer be able to hold a charge. Try replacing the batteries with fresh ones and the alternator as well.

Mower Leaving Streaks Or Lines Or Clumps Of Grass

There are several reasons why a Ferris IS2100Z mower may leave streaks, lines of grass, or clumps of grass. The blades being broken or dull is the most frequent reason. The blades won’t cut the grass uniformly and will produce streaks if they are worn. If the blades are damaged, they may tear the grass, resulting in lines or clumps of grass.

Moreover, if the deck isn’t level, the blades will not cut the grass evenly, resulting in streaks or lines.

Solution: The problem can be fixed by sharpening the blades or replacing broken ones. The blade should be replaced as soon as it becomes dull. Use a sharp, mower-specific blade. You may also need to level the deck if it is not level.

Machine Vibrates Excessively

There are many reasons why the Ferris IS2100Z mower machine may vibrate excessively. Understanding the issue’s core is essential for developing the appropriate solution.

Among the most typical causes is an imbalance in the blades. When the blades aren’t steady, they make the mower shake too much. Another common reason for excessive vibration is incorrect belt installation.

Solution: The best way to fix a mower that vibrates too much is to ensure the blades are balanced and the deck is level. Contact a Ferris dealer for assistance if you have difficulty balancing the blades. If you are having difficulty leveling the mower blade, you can adjust the leveling bolts on the blade to 94Nm.

Engine Knocks And Excessive Oil Consumption

You may have noticed that the engine occasionally knocks and consume excessive oil. Mainly oil is the main culprit here.

Solution: Even though these disturbances can be disconcerting, they are typically unimportant and straightforward to correct. If low oil is the cause of the issue, add oil as needed. If you are using the wrong oil then try to follow the manual to fix this. Or, if the case is regarding too much oil in the crankcase, you’ll need to drain the excess oil from the engine.

The Machine Is Difficult To Steer

The Ferris IS2100Z’s design is primarily to blame for how difficult it is to steer. The significant mower’s weighty cutting deck makes turning it challenging. Turning is challenging due to the mower’s wheels being placed closely together.

Solution: To this issue, there are several solutions. Adding weight to the mower’s front end is one solution. Distributing the cutting deck’s weight evenly will facilitate turning. Wheel positioning modification is another option. Moving the wheels in either direction will accomplish this. The mower will be simpler to turn in either direction as a result.

Deck Belt Failure

According to some owners of the Ferris IS2100Z zero-turn mower, their mowers’ deck belts failed after using the mower for only 28 hours. This problem occurs when you engage and disengage the PTO at the wrong speeds. Engaging and disengaging the PTO at the wrong speeds might lead to deck belt failure or the deck belt jumping from the pulley.

Solution: To solve this problem, you need to engage and disengage the PTO at the correct speeds. To engage the PTO, you may set your mower’s throttle to a half-throttle position and for disengaging the PTO, set your mower’s throttle to an idle throttle position.

Unstable Mower Deck

Sometimes, it might get unstable after you step off your Ferris IS2100Z zero-turn mower and again step on the mower deck. Also, rather than being in a solid position, your lawnmower rocks freely up and down when you push on it. This problem happens when the mower deck is not leveled, or the deck hanger is broken. A user said regarding this issue in a forum of LawnWorld,

On a Ferris IS2100Z, the front deck hangers are attached to the Independent suspension arms and If you’re not on a level surface and one of the suspension arms is raised up a little bit, it does that……so when you go over a bump or very uneven ground, the deck stays mowing level instead of raising up like a fixed position mower. Check it on a level surface and if it still does that, the deck will need to be leveled.

Solution: The mower deck needs to be adjusted to solve this problem. Also, if the deck hanger is broken, then you need to replace it.
