How to Measure Your Mower’s Width and Choose the Right Mower for Your Backyard Gate

Buying a new lawn mower can be stressful, especially if your backyard is gated. One of the most common surprises homeowners face is realizing their mower doesn’t fit through the gate—even when mower size matches the listed gate width. This guide explains how to measure your mower, avoid fit headaches, and choose the right lawn mower for your property. By the end, you’ll know how to shop smart, save time, and maybe spare your fence a few dents.

The Truth About Mower Sizes: Cutting Width vs. Actual Mower Width

The number on your mower—whether it says 32, 36, 42, or even 60—refers to the cutting width, not the total width of the mower. This is a detail that trips up plenty of buyers.

A “36-inch” mower means it can cut a swath 36 inches wide in one pass. This is the length across the blades, from tip to tip. But the mower deck, plastic guards, discharge chute, and other pieces actually stick out past the blades. The machine’s real footprint is usually wider than the number on the side.

Here’s what that looks like for common deck sizes:

Labeled Cutting Width Actual Mower Width (approx.)
32 inches ~33-34 inches
34 inches ~35-36 inches (with flap folded)
36 inches ~38 inches (wider with flap)
42 inches ~47 inches (with flap down)
48 inches ~52-54 inches

Manufacturers list based on blade coverage, not the hardware. For example:

  • A 36-inch mower will often have two 18-inch blades.
  • A 42-inch mower might use two 21-inch blades.

Key takeaway: Always remember, cutting width is not the same as total mower width.

How to Measure Your Gate and Your Mower the Right Way

Before you dream about a new mower, get out the tape measure. Knowing your actual gate opening and understanding how to measure your mower can save you returns, frustration, and money.

Measuring Your Gate

Almost every fence gate is either about 36 or 48 inches wide. However, some backyard gates—especially older ones, or those custom-installed—can be a little off.

How to do it:

  • Measure the clear space between the inside edges of your gate opening. Don’t just measure the gate door itself.
  • Write this number down. You’ll need it at the mower store.

Measuring Your Mower

You don’t want to guess here. The right way to measure a mower is:

  1. Lock your tape measure. Make sure it won’t slide shut while you’re working.
  2. Slide the tape measure under the mower. Place it at ground level and stretch it across to the widest points of the deck.
  3. Account for the discharge flap. Most lawn mowers have a side discharge flap (the plastic part that shields things from flying debris). This piece often adds several inches.
    • Measure with the flap down (which is how you’ll be mowing).
    • For tight gates, fold the flap up for an alternate measurement, or (if safe and allowed by your mower design) measure with it removed.
  4. Double-check both sides. Sometimes deck shapes make one edge stick out farther.

Important details from the video:

  • With the flap down, a 36-inch mower measures about 42 inches at its widest.
  • Folding the flap up or removing it gets closer to 38 inches.
  • A 42-inch mower with the flap down often measures about 47 inches, or around 37.5 inches with the flap up (though this should be checked for the exact model).

Measuring Tips Checklist

  • Measure both with discharge flap down and up.
  • Allow for a quarter-inch to half-inch extra space for easier maneuvering.
  • Account for handles or axle ends that may stick out.
  • Write both measurements (gate and mower) down before shopping.

Safety Note: The discharge flap protects people, pets, and property from flying debris. Never mow without it attached in normal use.

Real-World Examples: Which Mowers Fit Which Gates?

36-Inch Gates

Many standard backyard gates are a true 36 inches. You might think a 36-inch mower will fit right through, but it doesn’t. The true width with flap down is about 42 inches; even with the flap up, it’s about 38 inches—still too wide.

Best Mower Option for 36-Inch Gates

Toro’s 32-inch GrandStand  or similar models are the right fit. These designs come in just under 36 inches, so they cruise through narrow openings with no problem.

48-Inch Gates

If you’re lucky enough to have a 48-inch gate, you’ve got many choices. Now, a 42-inch mower—even with the side flap down and at its widest—will fit easily. That means faster mowing and the ability to choose more powerful equipment.

For tight spots or swinging gates with bulky hardware, fold the flap up to squeeze through with a bit of extra room.

Remember: Even a 42-inch mower will not fit through a 36-inch gate, so check those numbers twice.

Quick Comparison Chart

Gate Width Mower Cut Size Will It Fit? Tips
36 inches 32 inches Yes Great fit, no hassle
36 inches 34 inches (flap up) Yes (may need flap up/off) Check deck shape
36 inches 36 inches No Too wide, even flap up
48 inches 42 inches Yes Flap down fits fine
48 inches 48 inches Yes (measure first) May be tight with flap

Why Go Bigger? The Benefits of Using the Largest Mower That Fits

It’s tempting to go small “just in case,” but sizing up your mower brings big rewards.

1. Save Yourself Time

A wider mower covers more ground with every pass. That means weekends spent with the family (or relaxing) instead of circling the yard for hours.

2. Get More Life from Your Investment

Lawn mowers, like cars, have a “mileage limit”—usually measured in hours. Suppose your mower is built to last 1,000 hours. If it takes you one hour to mow every week, you’ll get 1,000 cuts. If it takes two hours, you just cut that lifespan in half.

3. Reduce Maintenance Hassles

Cutting faster means fewer hours spent mowing, but it also means less frequent blade sharpening, fewer oil changes, and less time replacing air filters. Every maintenance cycle skipped is cash back in your pocket.

Quick benefits recap:

  • Time is money: Spend less of both with the right mower width.
  • Extend mower life: Fewer hours per mow, more years per machine.
  • Maintenance savings: Less sharpening, cleaning, and replacing parts.

Tips and Recommendations for Picking the Right Mower

Choosing the right mower is more than matching numbers. Here are some steps to get it right:

  1. Measure your gate opening carefully before shopping.
  2. Bring your measurements with you to the dealer.
  3. Test the mower width at the store (with the flap down and up).
  4. Aim for the widest mower that fits —within reason. Bigger means less time and money spent each year.
  5. Don’t forget about safety: The discharge flap keeps debris in check. Only fold it up for transport, not mowing.
  6. If unsure, ask for help. Your local dealer will gladly help you measure and suggest what fits.

Take it from the story of “Buster,” a customer who showed up at the shop with a gate measuring just 44 inches. Not all gates match standard sizes, so getting hands-on measurements at a mower store helps. The right advice will save you a return trip and maybe a few headaches.

Conclusion

Measuring your mower and gate the right way pays off with less stress and better results. Remember, a 36-inch mower is almost always too wide for a 36-inch gate—pay attention to the actual width, not just the advertised cut. Picking the biggest mower that fits will save you time and money for years to come.

If you’re ready for a smoother mowing experience, don’t forget to double-check that gate opening before heading to the shop. When in doubt, visit your local dealer or browse trusted stores like Main Street Mower for advice and the latest models. Happy mowing!
