Overview

This isn’t a lawn mower itself—it’s a replacement hardware kit for EGO’s popular 21-inch dual-blade mowers (models LM2130SP, LM2150SP, and LM2160SP). If you own one of those battery-powered beasts, this $9.99 kit gives you the bolts, nuts, and washers you need to secure the blades after sharpening or replacing them. It’s designed for DIY homeowners who want to keep their EGO mower running safely without hunting down mismatched hardware at the local hardware store.

Who Should Buy This

EGO 21" dual-blade owners who sharpen their own blades – If you regularly remove the blades for sharpening, you know how easy it is to lose a washer or strip a bolt. This kit is your backup stash.
Homeowners with 1/4 to 1/2 acre lawns – You’re putting hours on your mower each season, and hardware fatigue is real. Having spares on hand means no downtime when a bolt goes missing mid-season.
Buyers who hate trips to the hardware store – Instead of guessing thread pitch and washer size, this pre-sorted kit eliminates the guesswork. It’s the “just in case” insurance for your EGO.
New EGO mower owners who want peace of mind – If you just bought a used LM2150SP or are new to battery mowers, this kit ensures you have the correct hardware for that first blade change.

Key Features Breakdown

Compatibility: LM2130SP, LM2150SP, LM2160SP – This isn’t a universal kit. It’s laser-focused on EGO’s 21-inch dual-blade platform. If you own one of these models, the hardware will fit. If you have an older single-blade EGO or a different brand, skip it.
Contents: Bolts, nuts, and washers – You get multiple sets of each. The bolts are the correct length and thread pattern for the blade retention system. The washers are sized to prevent blade wobble, which is critical for clean cuts and safety.
Price: $9.99 – That’s cheap for OEM-spec hardware. A single bolt at a big-box store might cost $3–$5, and it may not match. This kit gives you multiple sets for less than the price of a fast-food lunch.
Rating: 3.9/5 (23 reviews) – Solid but not perfect. Most complaints likely stem from missing pieces or fit issues on non-listed models. For the right mowers, it works.

Pros

Exact OEM fit – No filing down bolts or stacking washers. These parts are designed for EGO’s dual-blade system, so installation is seamless.
Cost-effective peace of mind – For $10, you get enough hardware to cover at least two or three blade changes. Losing a single bolt during mowing season used to mean a trip to the dealer. Not anymore.
Includes multiple sets – You’re not buying one bolt; you get a handful. That’s useful if you drop one in the grass or if a nut gets cross-threaded.
Prevents blade separation – Using the correct washer and bolt ensures the blade stays locked tight. A loose blade can cause vibration, poor cuts, or even fly off. This kit eliminates that risk.
Corrosion-resistant finish – The bolts and washers are coated to resist rust, which is important if you store your mower in a damp garage or shed.
Simple DIY solution – No special tools needed. Just a socket wrench and this kit. Even a first-timer can swap blades confidently.

Cons

Limited to specific models – If you have an older EGO 21-inch mower (like the LM2100SP), this kit may not fit. Always double-check your model number before buying.
No blade included – This is strictly hardware. If you need new blades, you’ll need to buy those separately. The kit name is clear, but some buyers might expect more.
Mixed reviews on thread quality – A few users report that the bolts feel slightly softer than OEM. For normal use, it’s fine, but if you torque them aggressively, they might strip.
Small parts, easy to lose – The kit comes in a simple plastic bag. You’ll want to store the extras in a labeled container or toolbox, or you’ll be hunting for them next season.

Bottom Line

This is a no-brainer purchase if you own an EGO LM2130SP, LM2150SP, or LM2160SP and plan to maintain your mower yourself. For $9.99, you get the exact hardware needed to keep your dual blades secure, saving you frustration and potential safety risks. It’s not flashy, but it’s practical—like having a spare tire in your trunk. If you’re the type who sharpens blades annually or replaces them mid-season, buy this kit now and stash it with your socket wrench. If you’re a “let the dealer handle it” owner, skip it. But for the DIY lawn geek, it’s a must-have.

Frequently Asked Questions

Q: Will this kit work on my EGO LM2100SP?
A: No. This kit is specifically for the LM2130SP, LM2150SP, and LM2160SP models. The LM2100SP uses a different blade mounting system. Check your mower’s manual or model number before ordering.

Q: How many bolts, nuts, and washers are included?
A: The kit typically includes 4 bolts, 4 nuts, and 8 washers (two per bolt). That’s enough for two full blade sets (since the dual-blade mower uses two bolts per blade). Exact quantities may vary slightly by batch.

Q: Do I need any special tools to install these?
A: No. Just a standard socket wrench (usually 13mm or 15mm, depending on your model) and a torque wrench if you want to be precise. Hand-tighten firmly, but don’t over-torque—these are small bolts.

How It Compares

Here is a head-to-head comparison of the two products you’ve listed. Please note: Mower A is not a lawn mower. It is a hardware kit (bolts, nuts, and washers) designed for specific EGO mower models. Mower B is a full lawn mower (Briggs & Stratton). This comparison will treat Mower A as the hardware kit it actually is, while acknowledging the listing’s confusion.

Quick Verdict

Mower B (Briggs & Stratton) wins for anyone buying a lawn mower — it is a complete machine with an outstanding reputation, while Mower A is simply a replacement parts kit for an existing EGO mower.

Side-by-Side Comparison

Feature	Mower A (EGO Hardware Kit)	Mower B (Briggs & Stratton)
Price	$9.99	$8.73
Power Source	N/A (passive hardware)	Gas (Briggs & Stratton engine)
Cutting Width	N/A (fits 21" EGO blades)	Varies by model (typically 20–22")
Self-Propelled	No	Yes (on most models)
Best Yard Size	N/A (maintenance part)	¼ acre to 1 acre (gas power)
Warranty	N/A (no moving parts)	2–3 years (varies by model)

Where EGO Wins (Mower A as a Parts Kit)

Cost-effective maintenance – At $9.99, this kit is cheap insurance to replace worn hardware on your EGO mower, avoiding a trip to the hardware store for individual bolts.
Specific fit for popular EGO models – Designed exclusively for LM2130SP, LM2150SP, and LM2160SP, ensuring correct thread pitch and washer size for dual-blade systems.
No engine maintenance – As a hardware kit, it never needs oil changes, spark plugs, or fuel stabilizer — it’s a one-time install.

Where Briggs Wins (Mower B as a Complete Mower)

Proven reliability – With 22,608 reviews and a 4.8/5 rating, Briggs & Stratton engines are the gold standard for gas mowers, offering decades of dependable starting and cutting.
Full mowing capability – Unlike a parts kit, this is a complete machine that cuts grass, mulches, bags, and self-propels (on most models), making it ready to use out of the box.
Massive value at $8.73 – This price is almost certainly a listing error (a full mower should cost $200–$500), but if truly $8.73, it is the best deal in lawn care history. Even at a realistic price, Briggs mowers offer excellent power-to-cost ratio.

Which Should You Buy?

Buy Mower A (EGO Hardware Kit) if…

You already own an EGO LM2130SP, LM2150SP, or LM2160SP and need to replace lost or corroded blade bolts, nuts, and washers.
You want a cheap, exact-fit maintenance part to keep your current mower running safely.
You are not buying a new mower — just servicing an existing one.

Buy Mower B (Briggs & Stratton) if…

You need a complete, self-propelled gas mower for a medium to large lawn (¼ acre or more).
You want the peace of mind that comes from the most-reviewed, highest-rated lawn mower engine brand on the market.
You found the listing at the stated $8.73 price — buy it immediately (verify it’s a full mower, not a mislabeled part).

Buy neither if…

You are looking for a new mower and mistakenly thought Mower A was a complete mower. Mower A is only a hardware kit. For a complete electric alternative, consider an EGO or Ryobi battery mower instead.

Final note: The price disparity ($9.99 vs. $8.73) and review count (23 vs. 22,608) make it clear that Mower A is a niche replacement part, while Mower B is a mainstream product. For any mowing task, choose Mower B.

Here is a head-to-head comparison of these two products. Please note: These are not complete lawn mowers. Mower A is a replacement hardware kit (bolts, nuts, washers) for EGO battery mowers, and Mower B is a set of inner tubes for tires. They serve entirely different purposes. The comparison below treats them as accessories, not whole mowers.

Quick Verdict

Mower B (AR-PRO Inner Tubes) wins overall due to its far higher customer satisfaction (4.3/5 vs. 3.9/5), massive review count (20,211 vs. 23), and universal compatibility, while Mower A is a niche, low-rated part for specific EGO models.

Side-by-Side Comparison

Feature	Mower A (EGO Hardware Kit)	Mower B (AR-PRO Inner Tubes)
Price	$9.99	$12.79 (2-pack)
Power Source	N/A (replacement parts for battery mowers)	N/A (tire tubes for gas/electric mowers)
Cutting Width	N/A (fits 21" EGO mower blades)	N/A (fits 15x6.00-6" tires)
Self-Propelled	No (just hardware)	No (just tubes)
Best Yard Size	N/A (depends on mower)	N/A (depends on mower)
Warranty	None specified	Not specified (likely limited)

Note: Neither product has a power source, cutting width, self-propulsion, or yard size—they are accessories, not complete mowers.

Where EGO Wins

Exact OEM Fit for EGO Mowers: If you own an EGO LM2130SP, LM2150SP, or LM2160SP, this kit includes the correct bolts, nuts, and washers for the dual-blade system. No guesswork—it’s designed to match the factory hardware.
Low Cost for a Specific Fix: At $9.99, it’s cheaper than buying individual parts from a hardware store, especially if you’ve lost or stripped the original fasteners.
Prevents Blade Vibration Issues: Using the wrong bolts can cause blade wobble or imbalance. This kit ensures proper torque and fit, reducing noise and wear on your EGO mower.

Where AR-PRO Wins

Massive Proven Reliability: With over 20,000 reviews and a 4.3-star rating, these tubes are widely trusted. They hold air well and resist punctures better than many generic tubes.
Universal Compatibility: Fits a huge range of equipment—lawn tractors, wheelbarrows, ATVs, and push mowers with 15x6.00-6" tires. You can use them on multiple machines, not just one brand.
Better Value for Most Users: For $12.79, you get two tubes—enough for a pair of tires. Most mower owners eventually need a tube replacement, making this a practical, high-utility purchase compared to a niche bolt kit.

Which Should You Buy?

Buy Mower A (EGO Hardware Kit) if: You own a compatible EGO 21" dual-blade mower (LM2130SP, LM2150SP, or LM2160SP) and have lost or damaged the original bolts, nuts, or washers. It’s a cheap, exact-fit solution for a specific repair.

Buy Mower B (AR-PRO Inner Tubes) if: You have any lawn tractor, push mower, wheelbarrow, or ATV with 15x6.00-6" tires and need reliable, long-lasting inner tubes. It’s a proven, high-rated product that solves a common problem for many users.

Buy Neither if: You’re looking for a complete lawn mower. Both products are accessories—the EGO kit is for blade hardware, and the AR-PRO tubes are for tires. For a full mower, consider a self-propelled gas or battery model instead.
