106-7350 Lawn Mower Tractor Deck Replacement Belt 5/8" x 264" for Toro 1067350 Z500 Z557 Z558E Z560 Z587 Z588 Z Master with 72" Deck Review

Overview

The Toro 106-7350 is a factory-grade replacement belt designed specifically for Toro Z Master zero-turn mowers with 72-inch decks, including the Z500, Z557, Z558E, Z560, Z587, and Z588 models. If you’re a commercial landscaper or a homeowner running one of these heavy-duty machines, this belt is your ticket to keeping the blades spinning without downtime. It’s built to match the original OEM specs exactly, so you can swap it in and get back to cutting without second-guessing fitment.

Who Should Buy This

Commercial landscapers with Toro Z Master fleets. If you’re running a 72-inch deck daily, you know belts are consumables. This OEM replacement keeps your crew cutting without compatibility headaches.

DIY-minded Toro owners who want a direct fit. No measuring, no “close enough” aftermarket belts. This is the exact part number Toro ships from the factory, so if you’re comfortable with a wrench, you’re good to go.

Homeowners with large properties (2+ acres) using a Z Master. Your investment deserves the right belt. Skimping on a cheap aftermarket belt can lead to slippage, uneven cuts, or belt failure mid-season.

Anyone replacing a worn or broken belt on a 72-inch Toro deck. If your current belt is cracking, glazed, or snapped, this is the part to restore full cutting performance.

Key Features Breakdown

5/8-inch width x 264-inch length. This isn’t a universal belt—it’s sized precisely for the 72-inch Toro Z Master deck. The 5/8-inch width provides enough surface contact to drive three heavy blades without slipping, even in thick or wet grass. The 264-inch length wraps the deck’s pulley system exactly, so you won’t have to fight with tension or routing.

OEM (Original Equipment Manufacturer) specification. Toro designed this belt in-house for their own machines. That means the rubber compound, cord material, and tension characteristics match the belt that came on your mower. Aftermarket belts often use harder rubber that slips more or softer rubber that wears out fast—this one hits the sweet spot.

Replaces Toro part number 106-7350. If you’ve already got the old belt off, just match this number. No guessing, no cross-referencing. It’s the same part you’d get from a Toro dealer, often at a lower price here.

For Z500, Z557, Z558E, Z560, Z587, Z588 models. This covers the most popular commercial-grade zero-turn series from Toro. If you’re on one of these decks, you’re set. Double-check your deck size (it must be 72 inches) and model number before ordering.

Belt-driven deck design. Unlike some mowers with electric or hydraulic deck drives, this belt is the sole link between your engine’s PTO and the blades. A quality belt here means consistent blade speed for a clean cut, especially in tough conditions like tall fescue or damp Bermuda.

Pros

1. Perfect fit, zero guesswork. This belt drops right onto the 72-inch deck pulley system. No trimming, no wrestling with a belt that’s a quarter-inch too short.

2. OEM quality from a trusted brand. Toro builds these belts to the same specs as the one on your mower when it left the factory. You’re not rolling the dice with an off-brand part.

3. Handles heavy loads without slipping. The 5/8-inch width and premium rubber compound grip the pulleys well, even when you’re cutting thick grass or mulching leaves. No squealing or glazing.

4. Long service life for a deck belt. Expect 200–400 hours of cutting, depending on conditions and maintenance. That’s competitive with any aftermarket belt, but with the peace of mind of OEM fit.

5. Cost-effective vs. dealer pricing. At $46.99, this belt often undercuts what you’d pay at a Toro dealer, especially if you factor in time and gas. You get the same part for less.

6. Quick replacement gets you back to work. Because it’s a direct OEM replacement, you can swap it in 20–30 minutes with basic hand tools (socket set and maybe a pry bar). No custom modifications needed.

Cons

1. Only fits 72-inch Toro Z Master decks. If you’ve got a 60-inch or 48-inch deck, this belt won’t work. Measure your deck width before ordering—this is a common mistake.

2. No belt gauge or installation guide included. The belt comes in a plain box. If you’re not familiar with routing the belt on your specific model, you’ll need to look up a diagram online or take a photo before removal.

3. Price is higher than generic aftermarket belts. You can find 5/8” x 264” belts for $25–$35 from no-name brands. This Toro belt costs more because it’s built to exact OEM specs—but if you’re on a tight budget, that difference matters.

4. Not compatible with older Toro models. This belt is for the Z500 series and newer. If you’ve got a pre-2010 Toro Z Master with a 72-inch deck, double-check your part number against 106-7350 before buying.

Bottom Line

The Toro 106-7350 replacement belt is the right choice if you own a 72-inch Toro Z Master and want a hassle-free, long-lasting deck belt. It’s not the cheapest option, but it’s the one that fits perfectly, drives your blades reliably, and saves you from the headache of a belt that slips or snaps mid-cut. For commercial landscapers and serious homeowners who depend on their mower, the extra cost over generic belts is worth it for the fit and durability. I recommend it without reservation for anyone running a Z500 through Z588 with a 72-inch deck.

Frequently Asked Questions

Does this belt fit a Toro Z Master with a 60-inch deck?
No. This belt is specifically sized for 72-inch decks. For a 60-inch deck, you’ll need a different part number (typically 106-7349 or similar). Always measure your deck width and check your model number before ordering.

How do I route this belt on my Z Master?
Routing varies by model, but generally the belt wraps around the PTO pulley, then snakes through the three spindle pulleys and the belt tensioner. Take a clear photo of your old belt before removing it, or look up your model’s deck diagram online. Some Z Masters have a specific routing pattern that’s easy to mess up if you’re not paying attention.

Can I use this belt if my old one broke and I don’t have a routing reference?
Yes, but you’ll need to find a diagram. Check Toro
