Appropriate positioning of the blade is a must for mowing, and there is no rocket science! In fact, how efficiently you will be able to go through your task highly depends on the blade position. 

But the fact is, the positioning of the blade will not be similar in every case, as mower decks consist of either 2 or 3 blades. So let us break down the ideal position of these two mower decks to help you mow your lawn correctly: 

1. Blade Position on 2 Blade Mower Deck

The 2 blade mower deck is the most common one in the lawnmower industry. Indeed, professionals prefer positioning this blade at an angle of 90 degrees for an optimal outcome. 

That being said, positioning the blade perpendicular to each other is crucial, especially if you are a user of a timed deck.

Speaking of the orientation, the 3 blade mower deck does not require to be parallel, timed, or perpendicular. And they are not prone to touch or overlap each other for being equipped with staggered positioning. 

The middle blade is usually pushed toward the front, and the other two blades are slid toward the inside.

How to Install Mower Blades Correctly

Before you get into installing your mower blades, it is necessary to take a look at the owner’s manual at least once. In this way, you will be able to get familiar with the basic procedures and safety precautions

And whether you are going to install a new blade or replace the blade with a new one, the whole process is going to be the same. So do follow the given steps:

Step-1: Break the Connection from the Power 

Break the Connection from the Power 

At first, you need to confirm that the engine of the mower is totally free from getting power. In that case, take off the battery if you are a user of a battery-powered mower.

Similarly, eliminate the cable of the spark plug for your gas-powered lawn mower. For this type of mower, the oil must not saturate the filter. For that, keep the filter facing in an upward direction. 

Step-2: Get the Blade Bolt Loosen

Before you want to loosen the blade bolt, securing the existing blade is crucial by setting a piece of wood. We’d prefer to collect a 2×4” block that works better. 

Then, put on a pair of gloves to start loosening the bolt by moving it anticlockwise. A standard wrench will be okay to get the work done. 

Step-3: Examine the Old Blade 

Examine the Old Blade 

Once you have removed the old mower blade, it is better to examine it from head to toe. For instance, there might be cracks, damages, or dents around the blade, which can be a major obstacle in the future. In these cases, replacement is the only way to go. 

On the other hand, if the blade appears nothing but blunt, store it in a safe place so that you can sharpen it for the next use. 

Step-4: Install the Blade

While installing a new mower blade, ensure that the blade’s cutting edge is facing toward the rotation. Before you tighten the blade completely, do observe the blade’s balance. 

Or else, if it is unbalanced, you will face extensive vibrations while mowing, resulting in damaging the motor and mower deck!

Next, get into tightening the bolt with a combination wrench. However, some prefer taking assistance from a torque wrench to avoid both under-tightening and overtightening. Once you have done it, start the engine to check how the blade is spinning. 

Which Way Do Mulching Blades Go on a Riding Mower?

Most riding mowers have mulching blades mounted on the underside of the deck, facing downwards. There are usually two blades, although some models may only have one. The blades are positioned so that they cut the grass as it passes underneath the deck.

Mulching blades are designed for chopping grass clippings into small pieces so that bacteria and other organisms in the soil can easily decompose them.

This process is known as  ‘mulching’ helps fertilize your lawn naturally while saving you time and effort to dispose of the grass clippings yourself.

When changing or sharpening your riding mower’s blades, it’s important to ensure that they’re installed correctly.

If they’re not, the mower won’t cut properly, and you may end up with an uneven lawn.

Most manufacturers will provide clear instructions on changing or sharpening the blades and which way round they should go.

However, it’s always best to check with a professional before proceeding if you need clarification.
