Husqvarna Mower Vibrating Problem
There is no doubt that Husqvarna riding lawnmowers are the right choice when it comes to maintaining extensive lawns. It is true that even though they are reliable, one can expect that there will be issues that will cause you to stop using them.
The Husqvarna mower that you are riding or pushing makes a loud shaking sound as you are riding it or pushing it. When the engine is running, all mowers vibrate as a result of the vibration caused by the engine.
There are several reasons why Husqvarna mowers vibrate, including faulty engine mounting bolts, worn clutches, debris caught in the mower, and improperly installed blades. Husqvarna mowers can also experience vibration problems due to worn and damaged mower deck components.
We have compiled a guide that will help you troubleshoot and repair your lawn mower if you are experiencing excessive vibrations. It is possible that you will need to replace the blades and crankshaft.
The following steps will guide you through identifying and checking every item that could cause your Husqvarna to vibrate.
The following is a general guide to repairing your vehicle. To find more specific information about your model’s repair requirements, consult your owner’s manual.
Troubleshoot Why Your Husqvarna Mower is Vibrating
Wet and high grass needs to be cut
It will be difficult to mow high grass that is wet and thick. By setting the cutting height low, the product may be exposed to excessive vibrations due to excessive vibrations. Initially, the grass should be mowed at a higher cutting height. The height should be lowered and the area should be processed again at a lower cutting height.
A Husqvarna engine mounting bolt check
A motor mount, which is also known as a motor mounting bolt, is the structure that holds your engine in place. As the mower is running, vibrations will be felt throughout the lawn mower as a result of these bolts being attached to the engine.
Make sure that there are no loose bolts on these bolts after inspecting them. Make sure that any loose bolts are tightened and that any that are worn or broken are replaced as soon as possible.
In the event that you feel excessive vibration in your Husqvarna push mower after engaging the blade, you should check your engine bolts. This is because you own a Husqvarna push mower.
The engine has been damaged
The sound of the product will change if there is a break or damage in one of the engine cylinders which can cause vibrations and noise.
Blades of grass
Start the engine immediately if the mower vibrates excessively. A mower blade that is out of balance or has been damaged is likely to cause this problem. In the same way that an uneven load in a washing machine knocks around and makes more noise than usual, vibration occurs as a result of uneven weight distribution on the blade.
If the blade is out of balance, either because it has been sharpened incorrectly or because it has been injured, then it can cause this condition. Check the blade for damage and inspect whether there is an issue with the balance of the blade. This is if you believe your mower is vibrating excessively as a result of an issue with the blade. In the event that it is damaged, you need to replace it as soon as possible.
The blade should be sharpened so that it is balanced or replaced if it is out of balance. When trying to test the balance of a blade, all that is needed to do is hang the blade from a nail driven into a wall. The nail will pass through the center hole of the blade.
As the blade drops lower on the heavier side, the lighter side will be at a higher angle. The operator may be at risk of injury if they continue to operate the engine in the event of such an issue. This is because doing so could damage the engine irreparably and even result in the operator’s death.
Its a crankshaft
Lawn mower engines are powered by crankshafts. Pistons drive crankshafts in engines. Most walk-behind lawnmowers have direct blade attachments to their crankshafts which pass through the engine’s crankcase. The blade striking a solid object is the most common cause of lawnmower vibration issues. The crankshaft can be damaged by tree roots, rocks, buried stakes, or pipes.
Approximately 220 MPH is possible with lawnmower blades. All that energy has to be expended somewhere when the blade strikes a solid object. A crankshaft bends when torque is transferred. A bend of just a few thousand inches is often enough to cause vibrations in a mower. Eliminate other possible sources of vibration before diagnosing a bent crankshaft.
The blade will also be badly damaged if something hits the mower’s crankshaft hard enough to bend it. In order to resolve this issue, it would be wise for you to first replace the blade with an undamaged one and then test the mower again. A more complex test will need to be carried out if the vibration is still there and is causing you problems.
With the help of a dial indicator, the next step in the procedure is to check the crankshaft runout on the crankshaft. Mower blades, mounting hubs, and spark plugs need to be removed first. After mounting the dial indicator to the mower deck, the crankshaft can be checked. Read the dial indicator’s runout after slowly rotating the engine.
Anything over .003″ in crankshaft runout would indicate damage, regardless of the engine manufacturer’s specification. An amateur should not attempt to fix a mower with a bent crankshaft. You can save substantial amounts of money if you know how to do it yourself. For the bent crankshaft to be replaced, the engine must be completely disassembled.
A small engine shop might be able to give you a quote if that seems like too much of a repair job. Often, a shop will charge substantially more to repair such an engine than to replace it completely.
The Husqvarna Spindle Housing should be checked for worn bearings
When you engage your blades, your Husqvarna mower deck can vibrate due to faulty bearings in your spindle housings.
Check for movement or play in your blade’s bearings by holding each end and rocking it up and down. Gloves are an excellent way to protect your hands.
Spindle housings can be replaced with new bearings, or they can be replaced completely. Husqvarna models vary in this regard.
Deck belts and pulleys should be checked on Husqvarna machines
The next thing you should check is the belt and the pulleys on your Husqvarna. A mower can vibrate when its belt has slack in it, or when its pulleys are damaged if they are worn and have slack in them. As soon as you discover that the belt that’s attached to your mower has a glazed appearance, or that it’s shredded or stretched, it’s time to get a new one.
The deck can shake when your belt does not sit securely on the pulleys. This is because the pulleys are not sitting parallel to the deck due to a faulty bearing, and the pulleys are not making a parallel connection with the pulleys.
Observe each pulley slowly by hand in order to check the bearing. In order for them to turn smoothly, they should be tightened. A pulley needs to be replaced if you are experiencing restrictions or if you hear a bearing noise when you turn it.
In Summary/Conclusion
That’s all our team of experts had to say about the issues that commonly arise with Husqvarna riding mowers when they vibrate. When it comes to Husqvarna riding mower problems, you do not always have to fear that they are difficult to fix or intimidating.
It is recommended that you consult the owner’s manual when you encounter internal engine problems that you are unfamiliar with. However, you may need to send the unit to a reputable mechanic. Keeping equipment in proper condition is not as easy as one might think, and it is vital that safety is your number one priority when maintaining equipment.
