Learning how to start a Husqvarna lawn mower is the first step to a well-maintained yard. While the process is straightforward, following the correct sequence ensures a quick and reliable start every time. Starting a Husqvarna mower typically involves a specific sequence of engaging the brake, setting the throttle, and pulling the choke.
This guide covers all common models, from simple push mowers to riding tractors. We will walk you through pre-start checks, the starting procedure itself, and solutions for when your mower won’t start.
Following these steps will help you get your equipment running smoothly and safely.
How To Start A Husqvarna Lawn Mower
Before you pull the starter rope, a few preliminary steps are essential. These checks protect both you and the mower from potential damage. Always refer to your specific model’s manual for the most accurate instructions.
Essential Safety Precautions
Safety should always be your first priority when operating any power equipment. Never overlook these basic rules.
- Clear the mowing area of debris like sticks, stones, and toys.
- Ensure all bystanders, especially children and pets, are at a safe distance.
- Wear sturdy closed-toe shoes and protective eyewear.
- Only operate the mower in good daylight conditions or with adequate artificial lighting.
- Never remove safety devices or guards that are installed on the mower.
Pre-Start Checklist
Completing this quick checklist takes just a moment but can prevent most common starting problems. It’s a good habit to develop before every use.
- Check the Oil Level: Use the dipstick to ensure the oil is at the full mark. Low oil can cause severe engine damage.
- Inspect the Air Filter: A clean air filter is crucial for engine performance. A clogged filter can prevent starting.
- Verify Fuel Level: Use fresh, clean gasoline that is less than 30 days old. Stale fuel is a leading cause of starting issues.
- Examine the Spark Plug: Ensure the spark plug wire is securely attached. A fouled or damaged plug will need replacement.
- Look for Obstructions: Check the mower deck for caked-on grass and around the blade for any tangled debris.
Understanding Your Mower’s Controls
Familiarize yourself with the key controls involved in the starting process. Their location may vary slightly by model.
- Brake/Blade Engagement Lever: This lever must be engaged to start the engine on most models.
- Throttle Control: Often set to a rabbit symbol for starting. Some models have a fixed throttle.
- Choke Control: Used to enrich the fuel mixture for a cold start. It’s usually a lever or a primer bulb.
- Recoil Starter Handle: The pull-cord used to manually crank the engine.
- Ignition Key (Riding Mowers): Used to activate the electrical system and starter motor.
Starting A Husqvarna Push Mower
This procedure applies to most standard walk-behind rotary mowers with a Briggs & Stratton or similar engine. The steps are logical and easy to master.
- Move the mower to a flat, clear area of grass or pavement.
- If the engine is cold, locate the choke lever and move it to the ‘Choke’ or ‘Start’ position. For a warm engine, leave the choke off.
- Press the primer bulb three to five times if your model is equipped with one. This sends fuel directly to the carburetor.
- Grasp the handlebar firmly. On most models, you must also depress the blade control lever against the handle to engage the safety brake.
- With your other hand, pull the starter rope smoothly and briskly. Do not yank it to its full length; use a controlled pull. If the engine doesn’t start, repeat the pull two or three times.
- Once the engine starts, gradually move the choke lever to the ‘Run’ position. Let the engine warm up for about 30 seconds before mowing.
Starting A Husqvarna Riding Lawn Mower
Starting a riding mower or lawn tractor involves a different set of controls. The sequence is designed to prevent accidental movement.
- Ensure the parking brake is fully engaged. This is a critical safety step.
- Set the throttle control lever to the midway or ‘Choke’ position, especially if the engine is cold.
- Make sure the blade engagement knob or lever is in the ‘Off’ (disengaged) position.
- Place the gear shift lever in ‘Neutral’ or ‘Park’.
- Insert the ignition key and turn it to the ‘On’ position. You may hear a faint click from the fuel pump.
- Turn the key further to ‘Start’ and hold it until the engine cranks and starts. Release the key immediately once it starts. Do not crank for more than 10 seconds at a time.
- If the engine is cold, allow it to run with the choke on for a minute, then gradually adjust the throttle to the desired running speed.
What To Do If Your Mower Won’t Start
If you follow the correct procedure and the mower still refuses to start, don’t worry. Use this troubleshooting flowchart to identify the likely cause. Most issues are simple to fix.
Common Problems and Solutions
Here are the most frequent reasons a Husqvarna mower won’t start and how to adress them.
- No Sound When Turning Key (Riding Mower): Check the parking brake is set. Ensure you are sitting in the seat, as a safety switch may be engaged. Check the battery terminals for corrosion.
- Engine Cranks But Won’t Start: The most common culprit is old fuel. Drain the tank and carburetor and refill with fresh gas. Next, check the spark plug for wear or fouling.
- Engine Starts Then Dies Immediately: This often points to a clogged carburetor jet or a dirty air filter restricting airflow. The choke may also be stuck in the closed position.
- Starter Rope is Hard to Pull or Stuck: The engine could be hydro-locked from excess oil or fuel. Remove the spark plug and pull the cord to expel any fluid. Also check for a seized engine or a tangled blade.
- Clicking Sound from Starter Solenoid: On riding mowers, this usually indicates a weak or dead battery. Try charging or replacing the battery.
Seasonal Starting Tips
Proper storage is the key to easy starting next season. Taking a few extra minutes at the end of the mowing season saves frustration in the spring.
Preparing for Winter Storage
Follow these steps to winterize your mower and ensure it starts easily when you need it again.
- Run the mower to use up the fuel in the carburetor, or add a fuel stabilizer to a full tank and run for 5 minutes to circulate it.
- Disconnect the spark plug wire for safety.
- Clean the entire mower, especially the underside of the deck, to remove grass and moisture.
- Change the engine oil and replace the air filter if needed.
- Store the mower in a cool, dry place, preferably covered.
Spring Start-Up Procedure
After long-term storage, a few checks will help you start your mower without trouble.
- Reconnect the spark plug wire if it was disconnected.
- Check and top up all fluid levels: oil, fuel, and battery electrolyte (if applicable).
- Install a new spark plug. It’s an inexpensive part that greatly improves reliability.
- If you didn’t use stabilizer, drain any old fuel from the tank and carburetor before adding fresh gasoline.
- Perform a general inspection for any rodent damage or loose parts before starting.
Maintenance For Reliable Starting
Regular maintenance is the best way to guarantee your Husqvarna mower starts on the first pull or turn of the key. A simple schedule prevents most issues.
- After Every Use: Clean off grass clippings and debris.
- Every 25 Hours: Check the air filter, clean or replace as necessary. Sharpen or balance the mower blade.
- Every 50 Hours: Change the engine oil. Check the tire pressure on riding mowers.
- Every 100 Hours: Replace the spark plug and air filter. Grease any fittings if your model has them.
- Annually: Inspect the drive belts on riding mowers for wear and cracks. Clean the battery terminals.
Frequently Asked Questions
Where Is The Choke On A Husqvarna Lawn Mower?
The choke is usually a lever located on the engine itself or on the control panel near the throttle. It often has symbols for ‘Choke’, ‘Run’, and sometimes ‘Half Choke’. On many newer models, a primer bulb serves a similar function by pumping fuel to enrich the mixture for starting.
Why Does My Husqvarna Mower Only Start With Starting Fluid?
If your mower requires starting fluid to start, it indicates a fuel delivery problem. The engine is not getting enough gasoline from the carburetor. Common causes include stale fuel, a clogged fuel filter, a blocked carburetor jet, or a malfunctioning fuel pump on riding mowers. Using starting fluid regularly can damage the engine, so it’s best to fix the underlying fuel system issue.
What Is The Correct Starting Procedure For A Husqvarna Lawn Tractor?
The correct procedure is: 1) Engage the parking brake fully. 2) Set the throttle to the choke position. 3) Ensure the PTO (blade engage) is off. 4) Place the transmission in neutral or park. 5) Turn the key to ‘On’, then to ‘Start’. Release the key once it starts. Always consult your owner’s manual, as some newer models may have a slightly different sequence.
How Do You Start A Husqvarna Mower That Has Been Sitting?
For a mower that has been sitting, especially over winter, first drain all the old fuel from the tank and the carburetor bowl. Add fresh gasoline. Check the oil level and top up if needed. Inspect the air filter and clean or replace it. Finally, install a new spark plug. These steps address the most common issues caused by prolonged storage.
Why Won’t My Husqvarna Riding Mower Crank?
If the mower won’t crank at all, check the most common safety interlock switches first. Ensure the parking brake is set, you are firmly seated in the seat, and the blade engagement lever is in the ‘Off’ position. Next, check the battery connections for corrosion and test the battery’s charge. A blown fuse or a faulty ignition switch could also be the cause.
