Now, why am I targeting Husqvarna mowers specifically? Because I feel like today, most of gardener uses this brand’s lawnmower.

Also, Husqvarna has a reputation for carrying a standard design of riding lawnmowers. And so, it should work with other lawn mowers as well if you learn how to change blades on Husqvarna zero-turn mower. So Here We Go!

Tools to Gather for Replacement.

  • Get a pair of sturdy and comfortable working gloves.
  • SAE socket sets are also required for this.
  • Store a piece of drop cloth near.
  • Bring a flashlight or a similar source for lighting.
  • If possible, gather torque wrench.
  • Clean fabrics are required.
  • The cutting blades for replacement based on a specific model.
  • Some sort of eye protection.

Step 1 – Parking the Mower & Raising Deck.

You should bring the mower to a spot with a flat surface. Also, make sure the area is dry enough to not cause a problem. Next, you need to get the spark plug disconnected. This is essential to avoid any mishap with the engine. It could start in middle of the replacement process. And that’s terrifyingly dangerous while working with cutting blades.

Now next you need to bring the mower deck to a higher position. You should use the lift lever attachment to raise it up. This way the deck will gradually start to get towards you. Make sure it’s in the highest position.

You should find lever on the right side of mower. It should be somewhere between the engine shroud and steering wheel. This height adjustment needs rotation using a clockwise motion. And this way the mower deck will slowly come to its complete “up” position.

Step 2 – Low Gear Setting & Other Preparations.

You should find the transmission lever this time. Using it brings the tractor in low gear mode. This is possible with the transmission lever pulled back as much as possible. You’ll be able to find this lever somewhere in the rear tire fender on right.

You need to engage the parking brake now. Simply push it as much as you can to let it go towards the ground. It should go all the way until being stopped itself.

Now using a drop cloth simply set a place beneath mower deck. You should get geared up with work glove and eye protection. Hold the flashlight or torch in your hand while crawling under mower. You will also need the SAE socket wrench and a clean fabric.

Step 3 -Unbolting to Remove Blade.

You should look for the cutting blades. Here you can locate a total of three cutting blade attachment bolts. They should be at the very center of each cutting blade. You can take the help of a flashlight to figure these out. These nuts might have a lot of debris and caked-on grass-covered above. Use the cleaning rag you bought and wipe them nicely.

Now bring the socket wrench to work. You will attach the tool close to cutting blade attachment bolt. Simply use counterclockwise motion and turn it. In some cases, the bolt needs to get free for moving. You should use something hard enough to bang the wrench sharply. Your hand’s heel can also help here.

Using one hand maintains the grip of blade. Now with the other hand slowly start unbolting nuts. Make sure you are careful enough that the blades don’t fall over. Once bolt feels free, make a move to remove the blade.

Use the same method for removing rest of the blade attachment bolts. And then gradually bring the other two blades down as well.

Step 4- Attaching New Blade.

There should be a part you encounter while removing the blades. This is where the older ones use to attach specifically. It’s called a mandrel. You need to attach the new blade precisely on this part. There’s only one way this fits blade. So, make sure you are properly aligning the new blade here.

Also, be careful about the side up warning. These are often noticeable over the surface of blade. This side is basically facing opposite to ground. Now simply place new blade using the requirements. Insert the bolts for attaching them securely.

The best way is to use a torque wrench. Use the tool to torque bolts to 45-foot pounds for best results. You should use same blade reattachment method for the remaining two. Make sure to tighten every bolt using the same torque. It’s time to bring your lawnmower back to operational mode. You can simply reverse the entire blade-removal steps mentioned above to do so.

Question & Answers

While knowing how to change blades on a Husqvarna riding lawn mower, there could be quite a few common questions coming to mind. I’ve tried to answer some of them below.

How do you know if the mower blade is upside down?

While learning about changing blades on Husqvarna zero turn mower one thing that people often forget about is its positioning. There should be a stamp over the blade’s surface mentioning some terms for accurate positioning.
