Husqvarna Self-Propelled Lawn Mower Problems With Solutions
Over time, the Husqvarna self-propelled lawn mower might show different problems. Here is a list of various issues your lawn mower might face and their solutions.
1. Engine Difficult to Start
Sometimes, starting your lawnmower may be difficult, even after repeated attempts. It can happen due to any of the following reasons:
Spark Plug Failing to Fire
The spark plug may fail to fire and ignite the fuel. If the fuel does not ignite, how can the engine start? Check the spark plug for any built-up carbon. You must clean the spark plug and set the appropriate gap.
Also, if it’s been a long time since you replaced the spark plug, you must replace the old one with a new one to start the engine.
Problem With Fuel Filter
If the filter has fouled with time, remove it to clean or replace it. If the fuel filter works fine, check the fuel tank and the fuel you use.
Suppose the fuel you use doesn’t suit the Husqvarna self-propelled lawn mower, or you kept the fuel tank unused for a long time. In that case, empty the fuel tank and refill it with the correct fuel.
There’s also a chance that the air filter is getting blocked. If so, empty the fuel tank and check the air filter and the fuel intake system.
Choke Plate Not Closing Completely
At times, the choke plate may not close completely. It then creates engine problems. In such a case, you will have to adjust the choke plate. If the problem persists, you must check if the spark plug produces a spark and if the compression has the right specifications.
2. Using Excessive Fuel
Your Husqvarna self-propelled lawn mower may use more fuel than expected. It may increase your expenses. If that’s the case, it would be best to resolve the problem immediately.
There could be many reasons behind your lawn mower using excessive fuel, and you might need to run several checks on various parts.
Blocking of The Air Filter
If air filter gets blocked, the land mower will use excessive fuel. If that happens, you must check and clean the air filter.
Spark Plug Causing Spark
Does the lawnmower’s spark plug ignite enough spark? If not, this may lead to incomplete combustion of the fuel. In that case, you must replace the spark plug.
Problem With The Mower Blades
Dull mower blades may cause the engine to run at high rpm, thus consuming more fuel. Moreover, if any hard object is stuck in the cutting deck, it might also pressure the motor. Hence, you must replace the dull blades with sharp ones and remove any stuck objects from the cutting deck.
Improper Float Level in The Carburetor
An improper float level in the carburetor may cause it to remain open. Moreover, the engine’s compression may not meet the specifications, resulting in excessive fuel consumption. Hence, you must check the carburetor’s float level and adjust the engine’s compression.
3. Backfiring
There might be times when your Husqvarna self-propelling lawn mower may backfire. It could result from incorrect ignition timing and exhaust leaks associated with the lawn mower. It’s also a common problem caused due to the improper firing time of the engine.
An easy way to troubleshoot this problem is to check whether the carburetor and manifold bolts have the correct torque. If the torque is correct, you must check for head gasket leaks. It would help if you tightened the head bolts.
You must also ensure the throttle plate is completely closed, and the engine speed is appropriate. The fuel mixture may also need to be corrected. So, you must check it is neither rich nor lean. These troubleshooting steps must solve the backfiring problems associated with the lawn mower.
4. Mower is Not Moving Forward
Are you trying to move your lawn mower forward, but it is stuck at a point? Then, you must check the drive cable of your Husqvarna self-propelled lawn mower. Suppose the drive cable is not functioning well. In that case, it might fail to activate the transmission, thus keeping the mower from moving forward.
Hence, you must check if the drive cable is properly fitted. It must not be faulty, too loose, or too tight.
If it is too tight or elongated, adjust it in a way to fit it properly. If the drive cable is faulty, replace it with a new one.
5. Improper Mowing
Improper mowing may result from damaged lawn mower blades. The blades might become dull with time or unaligned. Moreover, debris may get stuck to the blade while mowing grass, thus making it uneven and damaged.
In such cases, you must check if the blade needs replacement. If the blade is sharp but unaligned, you must align it and ensure the blade adapter is properly installed.
