How To Fix Problems With Husqvarna Riding Mowers?

You’ll learn about the five most typical riding mower problems here. You’ll know the problem with your mower once you’ve completed this step.

Riding Mower Will Not Start, There Is No Click

Natural maintenance difficulties can sometimes prevent your Husqvarna commercial mower from starting. Specifically, if your lawnmower…

• The engine has become flooded.
• Has insufficient petrol in the tank
• The freewheel control is not set to ‘Engaged.’
• The ‘Disengaged’ state of the attachment clutch is not set.
• There is no position on the control lever.

Then you’re likely to have trouble starting the mower. So double-check that you’ve done everything correctly. If the machine still doesn’t start, you’ll need to address more serious concerns.

Defective Spark Plug

A damaged spark plug is one of the most typical reasons for the Husqvarna riding mower not starting. If you look closely, you can notice:

• The insulator made of porcelain has cracked.
• There could be a lot of carbon on the electrode.
• The electrode has been damaged or destroyed.

In this case, the spark plug should be replaced. Now you might wonder, “How do I know the spark plug is bad?” On the other hand, a spark plug tester will make your journey easier. A significant spark should appear between the tester’s terminals when the engine starts. However, if you notice no spark, the spark plug is the villain here. So, replace it right away.

Clogged Carburetor

The blocked carburetor is the second most common cause of your mower not starting. When you keep fuel in your mower for an extended period, the different ingredients in the fuel may evaporate. It also produces a stickier, thicker fuel residue that might block the carburetor and finally prevent the engine from starting.

It can occur simply as a result of faulty or old gasoline. As a result, proper gasoline should be a priority for you. Deal with the carburetor instead if you know the gasoline is just acceptable. To deal with a clogged carburetor in the first place, use a carburetor cleaning. If you find it ineffective, you’ll have no choice but to entirely repair or replace the carburetor.

Defective Fuel Pump

When the engine is overfilled with oil, this happens. Let’s start with the functions of the fuel pump to understand it better. There are three ports on the fuel pump:

• The pulse port
• The gas-in port
• The gas-out port

There is a link between the engine crankcase and the pulse port, made by a short rubber tube. When you start the engine and crank it, the air in the crankcase alternately pressurizes and depressurizes. The gas is pumped using pressured air. However, if the engine is saturated with oil, sufficient oil may center the pulse port line, preventing the pulse port from working properly.

Another issue may arise due to the fuel pump’s check valves. The check valves prevent fuel from entering the gas tank when they fail. As a result, you should also inspect the valves. Replace the fuel pump once you’ve determined the problem.

Defective Ignition Coil

Because the ignition coil supplies voltage to the spark plug when the engine is running, it is directly connected to it. One of the most common causes of your mower not starting is a faulty ignition coil.

So, if you’re certain there’s no problem with the spark plug and only the ignition coil is malfunctioning, replace the coil. An ignition coil tester can be used to verify the ignition coil’s functioning.

Clogged Fuel Filter

As a result, things are nearly identical to the carburetor. It might get stickier and thicker when old fuel is left in the mower for an extended period. Because of the sticky fuel, the fuel filter may clog and prevent the engine from starting. Drain the petrol from your tank and replace the fuel filter if possible.

Broken Recoil Spring

The recoil spring has to recoil the rope on a pulley when you pull the starter rope. However, a broken recoil spring will not allow the rope to recoil onto the pulley. It eventually stops the spring from correctly turning over the engine, resulting in the engine failing to start.

Husqvarna Riding Mower Won’t Start After Running

Assume that your best mower has started to lose power during mowing. There are various reasons why a Husqvarna riding mower will not start after being run. Perhaps your mower has run out of gas or is choked with too much grass. This problem might also be caused by an outdated spark plug or a filthy air filter. Here are the specifics:

Inadequate Fuel

You can replenish the engine and try again if there is any shortfall of inadequate fuel. The issue must be resolved. If the mower still doesn’t start after being refilled, there may be some debris in the gasoline. When the fuel runs out, the debris may float upon it or be pulled inside it. As a result, you may end must clean and clear the fuel lines. Yes, this should solve the issue quickly.

Clogged Grass

If you cut too long grass with your riding mower and the grass becomes jammed, it may not perform properly. If this prevents your mower from starting, wipe out the debris and set the cutting height appropriately.

Old Spark Plugs

The mower may not restart if you cannot ensure that the spark plugs are clean, in good condition, and properly attached. So, if the plugs are old or unclean, examine them and replace them.

Dirty Air Filter

If you discover that the mower has lost power and won’t restart, it’s possible that unclean air filters are to blame. Inspect the air filter and clean it if necessary. Then try once more. However, replace the air filter if you still can’t handle it. 

Mower Blades Won’t Engage

The lawnmower blades won’t engage if the PTO clutch isn’t receiving power, if the clutch solenoid is broken, or if the clutch is worn out. If the PTO clutch is damaged, you must replace it because it cannot be repaired. The PTO switch supplies power for the PTO clutch.

Another typical question among Husqvarna riding mower owners is why the blades will not engage. When the PTO switch fails, the deck belt is damaged, the engine belt is damaged, and the battery is low on charge. The engine blades will also not engage if the safety switch is activated or if the blade clutch is malfunctioning. Let’s go over each issue in greater depth.

Faulty PTO Switch

The PTO (Power Take-Off) switch supplies enough power to the PTO clutch, delivering the power to the operator. Finally, this power is sent to the drive belts, which engage and rotate the blades. The blades do not engage or turn on when the PTO clutch does not have enough power.

As a result, you must ensure that the PTO switch is in good working order. A multimeter can check the switch’s power supply and consistency. You should replace your PTO switch if you observe any inconsistencies in the power supply.

Damaged Deck Belt

The damaged deck belt is another reason why the blades won’t engage. The deck belt is in charge of the blades’ rotation and the optimal pulley mechanism. Place your mower so that the lower deck is at the lowest setting to see if the deck belt is the problem.

Then, if there is any mud or debris, clean it up. Examine the deck belt for wear or damage. If you detect that the belt is misplaced and that this is the problem, you can reinstall the belt, and things will return to normal. However, if the belt is damaged, you should replace it with a new one. 

Damaged Engine Belts

After you’ve confirmed that the deck belt is in good working order, you’ll want to look at the engine belts. The blades of your Husqvarna riding mower may not operate properly if the engine belt is strained, broken, or worn out.

Replace the drive belt in this scenario, and the problem should be resolved. Furthermore, if the belt is not properly installed, the blades will not engage. Make sure it’s mounted correctly; in this case, carefully reading the owner’s instructions will assist. 

The Mower Engine Is Smoking

‘Why is my Husqvarna riding mower engine smoking?’ is one of the most commonly requested questions. The main reason is that the engine gets inundated with oil. If you’re certain there’s no surplus oil, your engine may be losing its crankcase suction.

Crankcase vacuum loss is caused by problems such as faulty engine breather assembly, an incorrectly positioned dipstick, etc. You can remove them if there is only surplus oil. However, there is no way to fix the other problems without replacing the defective parts.  

Excessive Vibration

Is your Husqvarna riding mower causing you any weird or excessive vibrations? If you answered yes, your mower’s blades, spindles, or pulleys might be bent or damaged somehow. It occurs when you mow over large items such as boulders, sewage lids, roots, and other large objects. However, any broken element can be easily replaced.

A twisted or damaged belt is another villain that performs such a detrimental role here. Make sure that all of the belts are correctly routed and that they are in good condition. You should also replace the belts if they exhibit any signs of wear. 

The Mower Battery Keeps Dying

Your mower’s alternator is in charge of the entire charging system. Your Husqvarna riding mower’s battery runs out of 12 volts. However, when the mower is in regular use, it cannot sustain the essential energy to keep it running.

The alternator produces 14 volts and then sends it to the battery. The battery can then be fully charged. The battery drains when the alternator fails, and your mower eventually stops working or develops additional problems.
