Belts Original 37x87 Murray Lawn Mower Compatible with Old # 37X87MA Review

Overview

The Belts Original 37x87 Murray Lawn Mower belt is a direct replacement part designed specifically for older Murray riding mowers and tractors that use the 37x87MA belt specification. Priced at just $15.95 with a solid 4.3-star rating from 81 reviews, this belt is built for homeowners who need a reliable, budget-friendly fix for their aging Murray mower deck—not for commercial operators or high-end zero-turn machines.

Who Should Buy This

1. Owners of vintage Murray riding mowers (1990s–early 2000s)
If you’re still running a Murray lawn tractor from the 90s or early 2000s, this belt is likely the exact match for your deck’s drive system. It’s a direct swap for the original 37x87MA part number, saving you the headache of hunting down discontinued OEM belts.

2. DIY mechanics on a budget
For under 16 bucks, this belt is an easy, low-risk fix for a slipping or worn deck belt. If you’re comfortable with basic tools and a socket wrench, you can install this yourself in under 30 minutes and avoid a $100+ shop visit.

3. Homeowners with 1–2 acre properties who run their mower hard
This belt holds up well under moderate use—think weekly cuts on 1–2 acres of grass. It’s not built for commercial abuse, but for typical suburban or rural mowing, it delivers reliable performance.

4. Anyone who hates mower downtime
Because this belt is widely available and inexpensive, you can keep a spare on hand. When your original belt snaps mid-season, swapping in this one gets you back to mowing fast.

Key Features Breakdown

Belt Dimensions: 37 inches (outside circumference) x 0.87 inches (width)
This is the critical spec. The 37-inch length fits Murray mower decks with a specific pulley setup, while the 0.87-inch width matches the original belt groove. Don’t guess—measure your old belt or check your mower’s manual before buying.

Compatibility: Works with Murray models using 37x87MA belts
This belt is not universal. It’s designed for older Murray riding mowers and tractors, particularly those with 42-inch and 46-inch decks. If you have a newer Murray (post-2005) or a different brand like Craftsman or Husqvarna, you’ll need to verify compatibility.

Material: Standard rubber and cord construction
It’s not a Kevlar-reinforced or heavy-duty belt, but it’s adequate for residential mowing. The rubber compound resists cracking from UV exposure and heat, though it won’t match the lifespan of premium aftermarket belts.

Price: $15.95
For the cost of a pizza, you get a functional replacement belt. That’s a bargain compared to OEM Murray belts, which can run $30–$50 and often require a special order.

Rating: 4.3 out of 5 stars (81 reviews)
The high rating reflects consistent performance for the price. Most buyers report easy installation and no issues with slipping or premature wear, though a few note it’s slightly thinner than OEM belts.

Pros

• Direct fit for older Murray models – No modifications needed. It matches the original 37x87MA spec perfectly for most pre-2005 Murray riding mowers.
• Budget-friendly price – At $15.95, it’s one of the cheapest ways to fix a broken deck belt. You can buy two for the cost of a single OEM belt.
• Easy to install – Most buyers report a 20–30 minute swap with basic hand tools. No special tensioning tools required.
• Decent durability for residential use – Holds up well for weekly mowing on 1–2 acres. Many users get a full season or more before replacement.
• Low risk purchase – With 81 reviews and a 4.3 average, you’re not gambling your money. It’s a proven, reliable part.
• Lightweight and easy to store – Keep a spare in your garage or shed without taking up much space. Great for emergencies.

Cons

• Not compatible with newer Murray models – If your mower was built after 2005, this belt likely won’t fit. Always double-check your mower’s belt part number before ordering.
• Slightly thinner than OEM belts – A few reviewers note the rubber feels a bit less substantial than the original. It may stretch faster or wear out sooner under heavy use.
• No heavy-duty reinforcement – This belt won’t handle commercial mowing, wet grass loads, or frequent deck engagement cycles without showing wear. It’s strictly for light-to-moderate residential work.
• Limited brand compatibility – It’s designed for Murray only. If you have a Craftsman, Husqvarna, or John Deere with a similar belt size, you’ll need to verify fitment—it’s not a universal replacement.

Bottom Line

The Belts Original 37x87 Murray Lawn Mower belt is a solid, affordable choice for anyone keeping an older Murray rider alive. It’s not the toughest belt on the market, but for $15.95, it delivers exactly what you need: a direct fit, easy installation, and reliable performance for typical residential mowing. If you’re running a pre-2005 Murray with a 37x87MA belt spec, this is a no-brainer buy—just keep a spare handy for next season. For commercial users or those with newer mowers, look elsewhere.

Frequently Asked Questions

Q: How do I know if this belt fits my Murray mower?
A: Check your mower’s owner’s manual or the old belt’s part number. If it’s stamped with 37x87MA or a Murray part number ending in 37X87MA, this belt is a direct match. Measure your old belt’s length (37 inches) and width (0.87 inches) to confirm.

Q: Will this belt work on a Craftsman or Husqvarna mower?
A: Only if your mower uses the exact same 37x87MA belt spec. Most Craftsman and Husqvarna models use different belt sizes, so you need to verify compatibility. Measure your old belt or check the manual before ordering.

Q: How long does this belt typically last?
A: For typical residential mowing (1–2 acres, weekly cuts, dry grass), most users report 1–2 seasons of use. Heavier use, wet grass, or frequent deck engagement will shorten its life. It’s a good idea to keep a spare on hand for mid-season failures.
