Best Lawn Mower Blades for Bagging: Top Picks for a Clean Cut

Few things frustrate a homeowner more than finishing a mow only to find grass clippings strewn across the driveway or clumped in wet piles on the lawn. Standard blades often just chew the grass and spit it out, leaving a mess that requires a second pass with a rake. Bagging demands a different tool—one engineered to create powerful airflow that stands the grass up, cuts it cleanly, and propels it into the catcher.

The secret lies in blade geometry. High-lift blades feature curved wings that act like a fan, generating suction that pulls clippings up and back. Mulching blades, by contrast, circulate clippings inside the deck to cut them repeatedly. For bagging, you want lift, and that means paying close attention to the blade’s design, material, and compatibility with your specific mower deck.

I’ve tested and compared five of the best lawn mower blades for bagging, spanning electric push mowers, gas riding tractors, and aftermarket replacements. This guide breaks down their strengths, their trade-offs, and exactly who should buy each one. You’ll also find a practical buying guide covering blade thickness, lift design, and installation tips.

EGO POWER+ High-Lift Bagging

The EGO POWER+ High-Lift Bagging Blade Set (AB2102D) is the dedicated answer for owners of EGO’s Select Cut mowers who want maximum performance from their bagging system. It’s a two-blade setup designed to replace the lower blade on the multi-blade system, specifically for models like the LM2130SP and LM2156SP. If your primary goal is a full, dense catcher bag with minimal shaking, this is the set to get.

This blade’s high-lift design is its standout feature. The pronounced wings generate substantial airflow that pulls clippings up and into the bag, which is essential when cutting taller grass or dealing with damp conditions. The all-steel construction keeps the edge sharp through multiple mows. It’s a simple swap that transforms how well your EGO mower collects clippings.

There is a trade-off you should know about. High-lift blades create more drag on the motor. On a battery-powered mower, that extra resistance can drain the battery faster than a standard or mulching blade. Expect to get slightly less runtime per charge, especially if you’re cutting thick, lush grass. It’s the price you pay for superior suction.

• Compatible with EGO LM2130, LM2133, LM2130SP, LM2135SP, LM2150SP, and LM2156SP models
• Functions as the interchangeable lower blade in the Select Cut system
• Designed purely for high-lift bagging action
• All steel construction for durability
• Measures 21 inches for a precise deck fit

Best for: EGO Select Cut owners who want the absolute best bagging performance and don’t mind a slight hit to battery runtime.

EGO POWER+ 21″ Mulching Blades

The EGO POWER+ 21″ Mulching Blades (AB2101D) are the versatile option for the same family of Select Cut mowers. This 2-pack gives you a spare, but more importantly, it offers a different cutting philosophy. While it’s branded as a mulching blade, it’s also rated for bagging, making it a solid choice if you like to switch between returning nutrients to the lawn and collecting clippings.

These blades are heavier duty than the standard ones that ship with many mowers. They’re designed to handle both tasks without compromising on cut quality. The multiple cutting surfaces help break down clippings into fine pieces when mulching, but the blade still has enough lift to push clippings into the bag when needed. It’s a true dual-purpose tool that saves you from constantly swapping blades.

The limitation here is that it’s a jack-of-all-trades, master of none. It won’t bag as aggressively as the dedicated high-lift AB2102D set, particularly when the grass is slightly wet or heavy. If you only bag a few times a season, this is perfect. If bagging is your primary method of grass removal, the dedicated high-lift blade is the better choice.

• Includes two blades for EGO LM2156SP, LM2150SP, LM2135SP, LM2130SP, LM2133, and LM2130 mowers
• Heavy-duty steel construction rated for both mulching and bagging
• Acts as the interchangeable lower blade on the multi-blade system
• Provides a clean cut to promote a healthier lawn
• 21-inch size fits the Select Cut deck perfectly

Best for: EGO owners who want one blade that can handle both mulching and occasional bagging without needing a dedicated setup.

Grasscool 138971 42 inch

The Grasscool 138971 blades are a direct replacement for a huge range of Craftsman, Poulan Pro, and Husqvarna riding mowers with 42-inch decks. This is an aftermarket part that bypasses the expensive OEM route. It’s specifically designed for blades with a 5-point star center hole, so you must check your current blade before ordering. This is a practical solution for budget-conscious owners of popular lawn tractors like the T110 and LT1000.

The main selling point is the fit. It matches OEM part numbers 138971 and 138498, which are common across many entry-level and mid-range tractors. The 42-inch length covers the full deck span, and the star center hole ensures a secure fit on the spindle. For a straightforward replacement, this gets your mower back in action without the dealership markup.

Here’s the catch: this is a standard replacement blade, not a specialized high-lift blade. It will bag adequately, but it won’t generate the same vacuum action as a dedicated high-lift design. If your Craftsman isn’t filling the bag completely or you’re picking up leaves, you might find this blade underwhelming. It’s best for standard grass collection duties.

• Replaces OEM parts 138971, 138498, and 532127843
• Fits Craftsman models including T110, LT1000, LT2000, and T3000
• Compatible with Poulan Pro PP19A42 and Husqvarna YTH18542
• Requires a 5-point star center hole (verify before purchase)
• Sized for 42-inch cutting decks

Best for: Craftsman and Husqvarna tractor owners looking for a direct, affordable replacement for standard bagging tasks.

Husqvarna 46-Inch High-Lift

The Husqvarna 46-Inch High-Lift Bagging Lawn Mower Blades are the OEM upgrade for riders with a 46-inch deck. This 2-pack replaces part number 403107 and is built to the exact specifications of the original equipment. It’s designed for owners of Husqvarna riding mowers who want a perfect fit and factory-tuned performance for bagging and mulching.

Husqvarna forges these blades from hardened steel, which means they hold an edge longer than softer aftermarket steel. The high-lift wings are aggressive, creating the powerful suction needed to lift grass and leaves off the lawn and send them into the bag. The star-mount design ensures a rock-solid attachment to the spindle, reducing wobble and vibration. They also run quieter than some generic blades, a nice bonus.

The downside is the premium price. You’re paying for the Husqvarna name and the guaranteed fit. There are cheaper aftermarket options that will fit the same deck, but they often use thinner steel that dulls faster. If you value longevity and consistent OEM performance, the cost is justified. Just make sure your deck is 46 inches, not 42 or 54, before you commit.

• Sold as a pack of two blades for 46-inch Husqvarna decks
• Replaces OEM part number 403107
• Features a star-mount for a secure, wobble-free fit
• Delivers 4-in-1 performance: bag, mulch, discharge, and side-discharge
• Constructed from hardened steel for extended edge life

Best for: Husqvarna rider owners who want a factory-perfect, high-quality blade that excels at both bagging and leaf pickup.

UDC Parts AB2102D Bagging

The UDC Parts AB2102D Bagging Blades Set is an aftermarket alternative to the EGO Power+ high-lift blade. It’s engineered to replace the OEM part AB2102D and fits the same lineup of EGO 21-inch Select Cut mowers. The main appeal here is potential cost savings while getting a blade that matches the original’s dimensions and lift profile.

UDC provides precise measurements, which shows they paid attention to the OEM design. The upper blade is 20-5/64 inches, and the lower blade is 20-13/64 inches, with a specific air lift of 13/16 inch. This isn’t a vague ‘fits most’ part; it’s dimensionally matched to the EGO system. The high-strength steel construction is designed to keep its cutting edge sharp and stable under heavy use.

However, you’re taking a chance on aftermarket quality control. While the specs match, the heat treatment and steel composition may not be identical to EGO’s factory blades. Some users report that aftermarket blades need more frequent balancing or sharpening. It’s a good budget option, but if you want guaranteed OEM performance and longevity, the genuine EGO blade is still the safer bet.

• Replaces OEM EGO Power+ part AB2102D
• Compatible with LM2130, LM2130SP, LM2156SP, LM2135SP, LM2150SP, and LM2133
• Includes both upper and lower blades for the Select Cut system
• Made from premium, high-strength steel
• Provides exact dimensional match to OEM specifications

Best for: EGO owners who want a high-lift bagging blade but are willing to try an aftermarket brand to save a few dollars.

How We Chose These Products

I focused on blade geometry first. Bagging performance hinges on lift, so I prioritized blades with pronounced wings or high-lift designs. I also looked for blades that could handle the specific challenges of bagging, such as wet grass and leaf pickup, which require significant airflow to move material.

Compatibility was the second major filter. A great blade is useless if it doesn’t fit your deck. I selected products that cover the most popular mower categories—electric push mowers from EGO and gas riding tractors from Craftsman and Husqvarna. I also weighed the value of OEM parts against aftermarket alternatives, considering factors like steel quality and the risk of fitment issues.

Buying Guide: What Really Matters

Before you buy, understand the difference between blade types. High-lift blades are the gold standard for bagging because their curved design acts like a fan, pulling clippings up and into the catcher. Mulching blades are designed to cut clippings into fine pieces and drop them back onto the lawn. If you plan to bag, look for high-lift. If you want a compromise, some blades, like the EGO mulching set, are rated for both but won’t excel at either compared to a dedicated blade.

Pay attention to blade thickness and material. Thicker, hardened steel blades will last longer and resist bending when you hit a rock or a thick root. However, they are also heavier. On an electric mower, a heavier blade requires more energy to spin. This is why you’ll notice a decrease in battery runtime when you switch to a high-lift steel blade. It’s a trade-off between cut quality and efficiency. If you have a large yard, consider having a spare battery charged and ready.

When it comes to installation, you need to be precise. Always refer to the blade replacement guide for your specific model. The most common mistake is not torquing the blade bolt to spec. A loose blade can slip or detach, causing serious damage. A blade that’s too tight can strip the bolt or damage the spindle. Check your mower’s manual for the exact torque specification, and always use a wrench to secure the bolt. After installation, spin the blade by hand to ensure it isn’t hitting the deck and that the spindle isn’t bent.

Finally, decide if you need an OEM part or if an aftermarket part is acceptable. OEM blades, like the Husqvarna or EGO options, guarantee a perfect fit and are made from materials specified by the manufacturer. Aftermarket blades, like the Grasscool or UDC parts, are often cheaper but can vary in quality. You need a grinding wheel for lawn mower blades to sharpen them, but you’ll need to do it more often with softer steel. Check the reviews for any aftermarket brand to see if other users have reported balance issues or premature wear.

Our Top Recommendation

The EGO POWER+ High-Lift Bagging Blade Set (AB2102D) is my top pick. For EGO Select Cut owners, it’s the most effective way to get a clean, full bag every time. The dedicated high-lift design solves the common complaint of clippings being left behind, and it’s a simple, direct replacement. The slight reduction in battery runtime is a fair price for the significant jump in bagging performance.

If you don’t own an EGO mower, the Husqvarna 46-Inch High-Lift set is the runner-up for riding mower owners. It’s a premium, factory-grade part that delivers excellent suction and durability. For those on a strict budget, the Grasscool 138971 is a reliable, low-cost replacement for Craftsman tractors, provided you check the star-hole configuration. It won’t give you high-lift performance, but it will get the job done for standard grass collection.

Frequently Asked Questions

Can I use a mulching blade for bagging?

Yes, but with reduced effectiveness. Mulching blades are designed to circulate clippings for fine cutting, not to create the high-velocity airflow needed to push grass into a bag. You may end up with clumps in the bag or clogging at the chute. A high-lift blade is always the better choice for dedicated bagging.

Why does my mower leave grass on the right side when bagging?

This is usually caused by the blade being installed upside down or the lift wings being worn down. If the blade is correct, check the discharge chute and bag for blockages. It could also be that your blade is dull and tearing the grass instead of cutting it cleanly, which creates a wider dispersal pattern.

How often should I sharpen blades used for bagging?

Sharpen them more often than you think. A dull blade tears grass, which makes it wetter and heavier, reducing airflow and causing poor bagging performance. For a standard suburban lawn, sharpening every 20-25 hours of use is a good rule of thumb. If you’re cutting wet grass or leaves, be prepared to sharpen more frequently.

Will high-lift blades damage my electric mower motor?

No, not if they are the correct size for your deck. The motor is designed to handle the load of a spinning blade. However, high-lift blades do create more drag, which increases the amp draw. This will drain your battery faster and could cause the motor to run hotter. As long as you’re using a blade designed for your specific mower model, you won’t damage the motor, but you might need a spare battery to finish the job.
