How to Change Blades on a Husqvarna Riding Mower, Step by Step

Husqvarna is one of the more popular lawnmower manufacturing companies. Their riding mowers with dual cutting blades appeal to a lot of customers and are suitable for both small and big yards. However, even the best machines require regular maintenance, as is the case for any lawnmower brand. Like other components of a Husqvarna mower, the blades must be in good shape for an optimal mowing result. When you buy a new Husqvarna lawnmower, its blades are sharp and healthy. But after some months of use, the blades become dull, resulting in poor cut grass. This can make your lawn look ugly and can even result in grass diseases.

Furthermore, dull blades consume more engine power, thereby increasing fuel cost. To avoid these situations, you should regularly check and sharpen the blades of your Husqvarna mower. But after sharpening the blades several times or hitting a rock or other debris, the blades will be worn out. They can become twisted and crooked, and the blade surface can be cracked. In these cases, it becomes imminent that the blades need to be replaced. Further sharpening won’t help or is impossible. This blog post will go through the steps to change the blades on a Husqvarna Riding Mower.

How to change the blades of a Husqvarna riding lawnmower, step by step:

Sources of Blade Damage:

The blades of a Husqvarna riding mower rotate at very high RPMs. At such high rotational speeds, impact with even the tiniest things can cause major damages. Over a long period of use, dirt and debris erode the blade cutting edge, making it dull and blunt. Hitting stones or toys or other hard obstacles can cause dents and twists. Corrosion is yet another source of blade damage. Chips and cracks also emerge on the blade surface over a long period of use, usually caused by the blade metal’s thermal expansion and contraction.

When you buy a high-end Husqvarna riding mower, clearly your goal is an eye-catching and healthy lawn. Bad blades can still cut grass, but poor blade quality will ruin your goal. Faulty blades cause several problems, including:

Lawn Mower Blade Replacement Guide

change, blades, husqvarna, riding, mower

Dull mower blades not only makes for a less than attractive finish to your lawn, but can also make it easy for disease to take a hold resulting in bare patches, unsightly grass, and a whole host of other issues.

When the blades on your lawn mower are dull, the engine needs to work harder to cut the grass. This additional requirement of power places the engine under added stress, which can result in it using more fuel, overheating or becoming damaged beyond repair over time. This is why it’s vital to make sure that your lawn mower blades are in good working condition at all times.

Before changing your lawn mower blades

Before you attempt to change the blades on your walk behind lawn mower, it is a good idea to refer to your service manual to confirm what safety precautions you’ll need to take, including safe work procedures and the use of appropriate PPE. If you do not have the appropriate experience to carry out the job, it is always recommended to take your lawn mower to a qualified repairer.

Step 1. Disconnect power

Begin by removing the spark plug cable from the spark plug to make sure that no power is delivered to the motor during the process. To prevent damaging the spark plug lead, be careful not to pull on the lead itself. Instead, firmly grip the lead plug where it joins the spark plug, twist it side to side to ensure it moves freely, then pull straight backwards.

Step 2 – Drain the fuel

Step 3. Loosen the blade bolt

Next, you want to secure the blade by placing a block of wood between the mower deck and the blade itself. Wearing safety gloves, begin to loosen the blade bolt by turning it counter-clockwise. Depending on the type of lawn mower that you have, there may be one or several heat treated blade bolts to undo, which may or may not have special washers attached to them. Refer to your service manual.

Step 4. Removing Replacing The Blade

Now you have removed your blade, inspect it for any damage. If there are signs of damage, cracks or dents on the blade, replace it. If you decide to sharpen the blades, start at the heavier end and just do a small amount at a time while paying attention to sharpening evenly across the face, until the blade is balanced. Never sharpen your blades to a knifepoint and try to allow for a 1mm edge.

If installing a new blade, you need to make sure that the cutting edge of the blade is facing the direction of rotation. The blade will have “this way up” embossed onto it. Ensure that the writing is facing toward the deck and that the star on the mandrel is perfectly aligned with the centre hole on the mower blade. Check the balance of the blade once more before tightening it into position. An unbalanced blade can cause intense vibrations that can lead to damage occurring to the mower deck and motor.

Step 5 – Tighten the Bolt

Place the blade bolt into the centre hole and then tighten it to a torque of 30-35Ft/Lb or 45–55Ft/Lb, depending on your mower type. It is important to check bolt specifications for your individual mower’s torque settings to ensure it is not over or under torqued. Avoid forcing the blade bolt when tightening it as this could cause the centre hole to develop small cracks that will worsen over time. Reverse the order of steps 1-2, then start your lawn mower and listen for any suspicious vibrations or sounds that occur with an unbalanced blade. Giving the underside of the deck a good clean to help prevent any debris or clippings from obstructing the flow of air and when combined with the new blades, could see your fuel costs drop by up to 25%.
