How to Start a Husqvarna Lawnmower, step by step


Lawnmowers help you keep your grass in check. Although there are many leading lawnmower manufacturers out there, Husqvarna has provided gardening enthusiasts with reliable models. If you want to start your Husqvarna machine but haven’t used this brand of lawnmower before, there’s no need to worry. This blog post covers all the information one needs to be aware of for starting a Husqvarna lawnmower.

How to Start a Husqvarna Lawnmower, step by step:

  1. Check the oil, gas, battery, and spark plug
  2. Insert the ignition key. For a push behind the lawnmower, you need to start the engine by pulling the rope three times.
  3. For riding lawnmowers, activate the parking mode by keeping the foot brake pressed.
  4. Retract the blades by turning the blade engagement lever off.
  5. Before starting your lawnmower. Set the choke to the top position.
  6. For starting the riding lawnmower mower, turn the ignition key. Throttle down once it has started.

There are two main types of lawnmowers, i.e., riding lawnmowers that resemble tractors and have a seat for you to sit. And push behind lawnmowers where you are walking behind the mower to steer it in the right direction, but the mower drives itself. The manual push-behind lawnmowers require you to carry the mower forward physically.

This article can help you with a basic step-by-step solution if you try to start your Husqvarna lawnmower.

Starting a Husqvarna Lawnmower, step-by-step:

For its consumers, Husqvarna manufactures two significant lawnmower types: the push mowers and the riding mowers. It is relatively easy to start a Husqvarna lawnmower and can be done by following these steps. Suppose you have any of the Husqvarna lawnmowers listed above. You should first follow some general guidelines in that case, which are mentioned below:

● 1. Oil Check:

It’s always necessary to check the engine’s oil level before starting any lawnmower. Located at the top of the engine is the black oil cap. Unplug the cap and examine the dipstick to get a glimpse into the oil level and condition. If the oil color is dark, it is not fit for use and must be replenished.

The engine should be filled with the oil listed in its user manual if the oil level drops below the ‘Add’ level on the dipstick. Fill the oil to the correct point and tighten the cap appropriately. Also, wipe any oil that has been leaked on the side and body.

● 2. Change the old fuel:

It is recommended that you should replenish the old fuel in the tank with fresh fuel injection if you start a Husqvarna lawnmower after a while. Over time, the fuel consistency declines, leading to the formation of deposits in the filter and carburetor. As a result, after starting, you may experience your engine having difficulty starting or stopping. As a toxic waste, take away the old fuel.

●3. Analyze the spark plug: 

Your machine’s front or side is where the spark plug is present. You can detach it with the help of a wrench. Then wipe it gently with a cotton cloth without damaging the electrodes.

● 4. Check the battery:

If the battery of your Husqvarna lawn mower is dead, the engine won’t start. Hence, test the battery terminals with a multimeter to check whether they provide any voltage.

Starting a Riding Husqvarna lawnmower:

We have explained the procedure for starting a Husqvarna riding lawnmower after you have performed the above steps.

 ● Step 1: Take your position

Take your mark on the mower in such a way that all the levers are accessible to you. Insert the ignition key, but don’t turn it around yet.

● Step 2: Activate the parking mode

Before starting the unit, parking mode must be initiated. Move the lever to park mode to do this. The parking mode needs to be activated when starting, but it needs to be deactivated to accelerate the mower.

● Step 3: Withdraw the blade lever

On the right-hand side of the fender is the blade lever. Make sure it is in the ‘off’ position, which guarantees that the blades are not active to start cutting.

● Step 4: Set the lever for the choke

Please change its level by bringing it to the highest position if your mower has a choke lever. You can switch it back to a position where the engine does not shut down once the lawnmower has started. Also, activate the neutral ‘N’ gear on the gearbox located at the front. 

● Step 5: Turn the key

Before the engine starts, turn the ignition key to the ‘Start’ location for around 10 seconds. Take it back to the ‘On’ position once it’s started.

Starting a Husqvarna Push Lawnmower:

It is comparatively simple to start a Husqvarna push -behind lawnmower and can be achieved by following the steps below. Assume you’re starting it after a long time, however. In that case, as explained before, we always recommend that you should perform the pre-starting operations such as fuel, oil, plug, battery check.

● Step 1: Check the spark plug wire

To see if it’s loose or not, tug the spark plug wire gently. Move it back up if it is loose.

●Step 2: Adjust the lever to the choke position

Your machine’s throttle lever is present in the stop position. It would help if you moved the lever to the “choke” position to start the engine.

● Step 3: Prime your engine

The cord on your engine should be pulled three times to prime your engine. Your engine starts without any problems if you have performed the maintenance pre-start measures correctly. If the engine doesn’t start after the third pull, you should troubleshoot for the causes of not starting.

● Step 4: Move the throttle lever to the highest position

If the engine with the throttle handle has started running, it’s going to run rough. Pull the throttle lever back to the ‘run’ potion to fix this. Resultantly, the engine runs smoothly now.

Related Questions:

1. What makes a lawnmower not start?

The likely causes of not starting a lawnmower may be the following:

  • Inadequate fuel: Checking your fuel tank and refilling it if it is empty is the most straightforward troubleshooting technique. You can proceed to the next phase if the fuel container is filled.
  • Defective spark plug: The spark plug’s electrodes may have been damaged or have developed carbon deposits on them. This defect may diminish the quality of the spark, leading to a loss of engine combustion.
  • Bad Air Filter: The air filter of your device is located just outside and is extremely likely to accumulate dust and foreign particles. As a consequence, the carburetor could not draw adequate for forming the air-fuel mixture.
  • Clogged Carburetor: Due to fuel deposits, carburetor jets are restricted over time. As a consequence, the air-fuel mixture is not adequately delivered, leading to a lack of combustion.
  • Constricted fuel filter: Dirt and debris can also clog the fuel filter. It may be one of the causes of this blockage.

2. Where is the carburetor on a lawnmower?

The carburetor is an engine component located internally, underneath the hood.  So, if, from the outside, it is not noticeable. Remove the air filter and its framework and detach it entirely to see the carburetor by removing the screws and the breather hose. Now, from the outside, it would make the carburetor visible to you.

3. How to clean a carburetor on a lawnmower without removing it?

A carburetor on a lawnmower can be cleaned without detaching it entirely from the mower’s body. The steps for doing that are given below:

  • Detach the air filter housing: The air filter’s housing holding the frame, the cover, and the air filter itself is wholly separated from the main mower body.
  • Detach the ducts: Detach the lines of fuel that gently connect with the carburetor. To hold all the depleted fuel, place a secure fuel container in front of it.
  • Remove the bowl nut: Remove the bowl from the carburetor by unscrewing the nut. This nut is a jet that has a high possibility of developing fuel deposits.
  • Spray the carburetor cleaner: Spray any brake or carburetor cleaner inside the carburetor so that any obstruction can be dislodged. Furthermore, pass a metal wire through the bowl nut to remove any deposits.
  • Reassembly: Once you’re done with the cleaning, you can assemble all the pieces back into the lawnmower.

4.  Why is my carburetor not getting any fuel?

There can be several reasons for your carburetor not drawing any fuel. We shall investigate those causes one by one.

  • Check the filters: Check for blockages or constraints in the fuel filter that could be why no fuel is acquired from your engine.
  • Check the fuel lines: You should investigate the fuel lines that lead to your carburetor and examine them for kinks and turns.
  • Inspect the carburetor: Inspect the carburetor to see if the needle valve is not stuck or the float does not prevent the fuel from being drawn into the carburetor.
  • Access the fuel pump: If your unit uses an electric fuel pump, check the fuse indicated in the fuse box for the pump carefully. It would help if you inspected it by connecting its intake to an external fuel source, such as a gas tank, in the mechanical pump case. If you pump the fuel from an external source, then the issue lies somewhere near your system’s fuel tank. So, it needs to be examined.

Final Comments:

Note that lawnmowers are machines that require care and proper maintenance quite frequently, much like your cars. Therefore, you should always do a quick check on fuel and oil items if you start the system after a long time. If it doesn’t start, it is possibly due to low fuel quality due to the carburetor jets’ deposits. You might pay some extra bucks to fix the carburetor in that case, so it’s better off that you take the precautionary actions in advance. If it is not possible to keep cleaning the carburetor and changing the fuel time and again, it might be better to purchase a fuel stabilizer. Typically, it preserves your fuel quality for around a year or so.
