Overview

The MTD Replacement Part 33" Mower Deck Assembly is not a complete lawn mower—it’s a heavy-duty OEM replacement deck designed for MTD-branded zero-turn mowers and tractors with a 33-inch cutting path. Priced at $370.21 with a middling 3.7-star rating from just five reviews, this part is best for owners of older MTD equipment who need to resurrect a worn-out deck rather than replace the whole machine. It’s a niche buy for the repair-minded homeowner or small-property owner who values keeping existing equipment running over buying new.

Who Should Buy This

Homeowners with aging MTD zero-turn mowers (2000s–2010s models) – If your original deck has rusted through, cracked at the weld points, or suffered impact damage, this assembly is a direct bolt-on replacement that can extend your mower’s life by years. It’s ideal for those who already own the compatible tractor and want to avoid a $1,500+ new mower purchase.
DIY mechanics and equipment restorers – If you’re comfortable with wrenches, jack stands, and a few hours of labor, this deck offers a cost-effective rebuild path. It’s perfect for tinkerers who buy used mowers cheap and bring them back to life.
Owners of 1–2 acre properties with flat or gently rolling terrain – The 33-inch deck is a mid-size cut—not too small for efficiency, not too large for maneuverability around trees and flower beds. It’s a good fit for properties where a 42-inch or 54-inch deck would be overkill.
Budget-conscious buyers who already have the tractor – At $370, this is far cheaper than a new mower. If your existing MTD machine is mechanically sound (engine, transmission, hydraulics), swapping the deck is the smart financial move.

Key Features Breakdown

33-inch cutting width: This is a sweet spot for residential zero-turn mowers. It’s wide enough to cover a typical suburban lawn in a reasonable number of passes, but narrow enough to slip through 36-inch gates and navigate tight landscaping beds. Expect to trim about 20–30% less than with a walk-behind.
OEM MTD replacement part: This isn’t a universal or aftermarket deck. It’s made to MTD’s original specifications, meaning bolt patterns, spindle heights, and belt routing should match factory tolerances. That’s critical—aftermarket decks often require drilling, shimming, or belt modifications.
Deck assembly (includes spindles, pulleys, and shell): The assembly comes as a complete unit with spindles and pulleys pre-installed. You don’t need to transfer parts from your old deck, which saves significant labor time. The shell is the stamped steel deck pan—durable but not indestructible.
Designed for MTD zero-turn mowers and tractors: This is both a feature and a limitation. It’s engineered for specific models (like the MTD 760, 760A, or certain Yard Machines variants). You must verify compatibility by checking your mower’s model number against MTD’s parts diagrams before buying.

Pros

Direct bolt-on replacement – No cutting, welding, or custom fabrication. If your mower is compatible, you can swap decks in a weekend with basic hand tools (socket set, jack, and maybe an impact wrench).
Pre-assembled spindles and pulleys – Many replacement decks require you to transfer or buy new spindles separately. This one comes ready to install, saving you $50–100 in additional parts and hours of disassembly.
OEM quality control – Because it’s an MTD factory part, the steel gauge, weld integrity, and paint thickness are consistent with what came on your mower originally. It should hold up for another 5–10 years of residential use.
Cost-effective vs. buying a new mower – At $370, it’s roughly 20–25% of the price of a new entry-level zero-turn. If your tractor’s engine and frame are solid, this is the most economical path to a like-new cutting experience.
33-inch size is versatile – It’s not so wide that it scalps on uneven ground, yet it’s wide enough to make quick work of a 1-acre lot. It’s a good compromise between speed and precision.
Better than patching a rusted deck – Many owners try to weld patches onto old decks, only to have them fail within a season. A new deck eliminates that headache entirely.

Cons

Limited compatibility – This deck fits a specific range of MTD models (primarily older 33-inch zero-turns). If you don’t have one of those exact models, it won’t work. There’s no universal adapter kit. Check compatibility carefully.
No blades or installation hardware included – You’ll need to buy three 33-inch blades (typically $30–50 total) and possibly new bolts, washers, and belt if your old ones are worn. Factor that into your total cost.
Mixed reviews and low rating – With only 5 reviews and a 3.7 average, there’s limited real-world feedback. Some buyers report fitment issues or slight manufacturing defects (e.g., misaligned spindle holes). It’s a gamble on quality consistency.
Heavy and awkward to ship – At roughly 50–60 pounds, this deck arrives in a large box that can be damaged in transit. Inspect immediately for dents or bent pulleys upon delivery.

Bottom Line

The MTD Replacement Part 33" Mower Deck Assembly is a solid, cost-effective solution for owners of compatible MTD zero-turn mowers who want to restore cutting performance without buying a whole new machine. It’s not for everyone—you need to be confident in your model compatibility and comfortable with a DIY install. But if you’ve got a mechanically sound tractor with a rotted deck, this is the smartest $370 you’ll spend. Just budget for blades and hardware, and inspect the package carefully when it arrives. For the right buyer, it’s a 4-star value. For everyone else, it’s a part that doesn’t apply.

Frequently Asked Questions

Q: Will this deck fit my MTD 760 zero-turn mower?
A: It should fit many MTD 760-series models, but you must verify by checking your mower’s model number (found on a tag under the seat or near the engine) against MTD’s official parts lookup. The deck is designed for specific 33-inch models from the late 2000s to mid-2010s. Don’t assume compatibility based on brand alone.

Q: Does the deck come with blades and a belt?
A: No. The assembly includes the stamped steel shell, pre-installed spindles, and pulleys, but you need to purchase three 33-inch blades separately. You may also need a new drive belt

How It Compares

Quick Verdict

The Greenworks 40V wins overall for most buyers due to its complete, ready-to-use design, far higher reliability rating (4.2 stars from nearly 12,000 reviews), and significantly lower price.

Side-by-Side Comparison

Feature	MTD 33" Deck Assembly	Greenworks 40V 16" Push
Price	$370.21	$249.99
Power Source	Manual (replacement part)	Battery (40V, 4.0Ah)
Cutting Width	33 inches	16 inches
Self-Propelled	No (deck only)	No (push mower)
Best Yard Size	N/A (replacement part)	Up to 1/3 acre
Warranty	None (part only)	4 years (mower), 2 years (battery)

Where MTD Wins

1. Massive cutting width. At 33 inches, this deck covers more than double the area per pass compared to the Greenworks 16-inch model. If you already have a compatible tractor or riding mower, this deck dramatically reduces mowing time on large properties (1+ acres).

2. Durable steel construction. MTD replacement decks are built from heavy-gauge stamped steel, designed to withstand years of use and abuse on rough terrain. The Greenworks is a lightweight plastic/composite push mower that won’t hold up to rocks, roots, or commercial-level use.

3. Part compatibility for repairs. This is a genuine OEM replacement part for many MTD, Cub Cadet, Troy-Bilt, and Yard Machines riding mowers. If your existing deck rusted out or cracked, this is a direct bolt-on fix that can extend the life of a $1,000+ mower for a fraction of the cost.

Where Greenworks Wins

1. Complete, ready-to-use package. The Greenworks is a full lawn mower with battery, charger, and push-button start. The MTD is just a metal deck—you need a compatible tractor, belts, pulleys, spindles, blades, and installation labor. Most buyers can’t use the MTD without already owning a specific riding mower.

2. Proven reliability and support. With 11,946 reviews and a 4.2-star average, the Greenworks has been tested by tens of thousands of users. The MTD has only 5 reviews (3.7 stars), and as a replacement part, you get zero warranty or customer support for installation issues.

3. Lower total cost and versatility. At $249.99, the Greenworks is $120 cheaper and includes a 4.0Ah battery that works with 75+ other Greenworks 40V tools (trimmers, blowers, chainsaws). The MTD requires a $370.21 investment plus potential additional parts (spindles, blades, belts) that can push the total to $500+.

Which Should You Buy?

Buy Mower A (MTD Deck) if: You already own a compatible riding mower (check your model number) and the existing deck is rusted or damaged beyond repair. This is the most cost-effective way to restore a large mower to full function, saving you from buying a whole new machine. Best for properties over 1 acre where a 33-inch deck is necessary.

Buy Mower B (Greenworks) if: You need a complete, ready-to-go mower for a small to medium yard (up to 1/3 acre) and want quiet, emissions-free operation with push-button start. This is ideal for homeowners who value low maintenance (no gas, oil, or spark plugs) and want a battery system that works with other yard tools. Avoid the MTD unless you’re certain it fits your existing equipment.

Neither is a good fit if: You don’t own a compatible riding mower and need to mow a yard larger than 1/3 acre. In that case, look for a gas self-propelled mower (e.g., Honda HRX) or a larger battery model like the Greenworks 80V 21-inch.

Here is a head-to-head comparison of these two very different lawn mowers.

Quick Verdict

The WORX WG743 wins for the vast majority of homeowners due to its complete, ready-to-use design, much higher reliability rating, and superior value for small yards, while the MTD deck assembly is a niche replacement part for specific repair needs, not a functional mower for a typical buyer.

Side-by-Side Comparison

Feature	MTD 33" Mower Deck Assembly	WORX WG743 17" Cordless Mower
Price	$370.21	$329.99
Power Source	N/A (Replacement part for gas/engine mower)	Battery-powered (20V, 2 included)
Cutting Width	33 inches	17 inches
Self-Propelled	No (requires mower frame/engine)	No (push mower)
Best Yard Size	Up to 1+ acre (if attached to a tractor)	Up to ¼ acre
Warranty	Varies by seller (typically 30-90 days)	3 years (standard WORX)

Where MTD Wins

Massive Cutting Capacity (33 inches): The MTD deck is over twice as wide as the WORX (33" vs 17"). If you have a large lawn (½ acre or more) and this deck is compatible with your riding mower or tractor, it will cut your mowing time in half compared to a small push mower.
Tractor/Zero-Turn Compatibility: This is not a standalone mower—it’s a replacement part for an existing machine. For owners of older MTD, Cub Cadet, or Yard Machines tractors, this deck is a cost-effective way to restore a broken mower rather than buying a new $2,000+ machine.
No Battery Limitations: Because it’s a mechanical deck designed to be powered by a gas engine or PTO, it doesn’t face battery runtime constraints. You can mow for hours continuously without recharging, which is critical for large properties.

Where WORX Wins

Complete, Plug-and-Use System: The WORX is a fully functional mower with two batteries, a charger, and a 7-position height adjustment right out of the box. The MTD deck is just a metal housing with blades—you cannot use it without a compatible tractor, engine, and drive system.
Overwhelmingly Better Reliability & Reviews: The WORX has over 7,000 reviews and a 4.1-star rating, indicating a reliable product that works for most buyers. The MTD deck has only 5 reviews with a 3.7-star rating, and many replacement parts have fitment issues or arrive damaged.
Lightweight, Quiet, and Low Maintenance: The WORX weighs roughly 40 lbs (vs. a 60+ lb steel deck alone) and is whisper-quiet electric. It requires no gas, oil changes, or spark plugs, and the 17" size makes it easy to maneuver around gardens, flower beds, and tight gates.

Which Should You Buy?

Buy Mower A (MTD Deck) if:

You already own a compatible riding mower or lawn tractor (MTD, Cub Cadet, Yard Machines) and the deck is rusted or broken. This is a repair part, not a mower for a new buyer.
You have a very large lawn (1+ acre) and need a 33-inch cutting width to save time. But note: you must also have a working tractor to attach it to.
You are a DIY mechanic comfortable with installation, alignment, and belt routing. This is not a simple bolt-on for most users.

Buy Mower B (WORX WG743) if:

You have a small to medium yard (under ¼ acre) and want a complete, ready-to-mow solution that works immediately. This is the best choice for 95% of home buyers.
You prioritize quiet operation, light weight (easy to carry or store), and zero maintenance. The WORX is ideal for homeowners who want simplicity.
You want a proven product with thousands of positive reviews and a 3-year warranty. The MTD deck is a high-risk, low-review purchase that may not fit your tractor.

Buy Neither if:

You need a self-propelled mower (hills, large yard) or a mower for a yard between ¼ and ½ acre. The WORX is too small for that, and the MTD deck is not a standalone mower. Consider a 21" self-propelled gas or battery model instead.
