Exmark Metro 32 vs. 36 vs. 30 Mowers (Cut Test)

The 30-inch deck is the most agile of these nominal widths; 32 inches adds 6.7% more cutting width, and 36 inches adds 20% over 30. Those figures do not prove faster mowing or a cleaner cut. A fair comparison needs the exact models, matching conditions, correct setups and repeated timed passes.

Choosing between a 30-, 32- and 36-inch Exmark walk-behind comes down to more than deck width. A wider deck may cover more ground on an open lawn, while a narrower one may be easier to guide around trees and tight beds. Cut quality also depends on blade condition, mowing height, grass and setup.

There is an important model-name detail: “Metro 30” and “Commercial 30” are not interchangeable names. Before applying any test result, identify each mower by its model and serial information, then check the matching Exmark operator’s manual. Engine, blade, deck and drive details can vary by model year and configuration.

I would not call a comparison a cut test unless the machines mow comparable strips under controlled conditions. The method below helps you compare them without treating a theoretical width advantage as a measured productivity gain.

Equipment Setup and Safety Preparation

Definition: This stage identifies the exact mowers and prepares them for a safe, fair comparison. It matters because two decks with different nominal widths may also have different blades, controls or setup instructions. Confirm each mower’s manual before adjusting, inspecting or operating it.

Start with the model and serial identification on each machine. Find the matching manual, then check its instructions for blade setup, engine speed, cutting-height adjustment and safe inspection. Do not assume those details from deck width or from another year’s machine.

Before each run:

• Inspect guards, discharge control, tires, blades, fasteners and operator controls.
• Confirm that each mower is set up as its manual directs.
• Clear the test area of people, pets, stones and loose debris.
• Wear eye and hearing protection, sturdy footwear and long trousers.
• Use the specified blade and deck setup for that exact mower.

Set the cut height to the same measured height on all machines where their adjustment systems allow it. A matching number on separate height controls does not always prove that the blade-to-ground height is equal. Measure the actual setup using the method described in the manual, with the engine off and the machine secured.

Do not standardize parts that should remain model-specific. Blade count, blade part number, height steps, rated engine speed, blade-fastener torque and drive arrangement can depend on configuration. Record what the manual specifies; do not fill in missing details by guesswork.

Field Cut-Test Procedure and Landscaping Performance

Definition: A useful field test compares cut quality and elapsed time on similar turf, with the operator and setup kept as consistent as possible. Run open-area passes and tight-turn work separately. This shows whether a wider deck’s coverage helps on that lawn or whether maneuvering changes the result.

Choose comparable, level strips in the same lawn. Use the same turf type and similar grass height, moisture and density. Avoid comparing one mower on dry, short grass with another on damp or overgrown grass; those conditions can change clumping and discharge.

Record the cut height, turf condition, strip width and length, and elapsed mowing time. Keep the engine at the speed specified by each mower’s manual and walk at a steady, similar pace. Use each mower’s correct blade and deck setup. Make matched passes with consistent overlap, then repeat the runs if conditions remain stable.

Assess these results separately:

• Cut uniformity: Look for an even finish and consistent grass height.
• Missed strips: Check for uncut lines between passes.
• Clumping and discharge: Note whether clippings spread evenly or gather in piles.
• Scalping: Look for areas cut much shorter, especially over uneven ground.
• Time and handling: Record total time, turn effort and difficulty in tight spaces.

A comparison table helps keep the result grounded. The percentages below describe nominal cutting-width differences only. They are not observed time savings or guaranteed gains in area per hour.

A wider deck can cover a wider strip in one pass, but actual productivity also depends on overlap, turns, terrain, operator pace and interruptions. Do not multiply the width percentage by a mowing-time estimate and present it as a test result. Measure time on the same area instead.

Field scenarios, not claimed test results: On an open, level lawn, the 36-inch deck may have a coverage advantage if the operator can make long, steady passes. On a yard with narrow gates, close-set trees or tight beds, a 30-inch deck may be easier to position. The 32-inch option sits between those widths, but its real value depends on access and the actual machines being compared.

I would report the test in two parts: open-area performance and tight-turn performance. A single total time can hide a useful trade-off. If one mower finishes the straight strips quickly but takes longer around obstacles, show both results rather than declaring a universal winner.

Maintenance, Blade Inspection and Sharpening

Definition: Blade condition is part of the test, not a minor detail. A damaged or dull blade can affect the finish and make a mower look worse than it would with a sound blade. Inspect safely, follow the exact manual and keep blade condition as equal as practical.

Before testing, compare the blades for visible damage and wear. Use only the blade specified for each mower’s configuration. If one blade is freshly serviced and another is visibly dull, the cut test cannot fairly isolate deck-width or mower-performance differences.

After mowing, stop the engine, disengage the blade and wait for all motion to cease. Before inspecting or cleaning, follow the manual’s steps to prevent an accidental start. Never reach under a running mower or a mower with a merely disengaged blade.

If a blade strikes a concealed stone or other hard object, stop the engine and wait until all motion has stopped. Disconnect the spark-plug lead, or otherwise disable starting as the manual directs. Inspect the blade and mower before restarting. A strike can damage a blade or throw debris; do not resume mowing until the machine is safe.

After the machine has cooled, remove packed grass only as the manual permits and with the mower secured as directed. Check the deck and blade again for damage. For sharpening, blade removal, balancing and fastener tightening, use the instructions and specifications for that exact model. Do not apply a torque value or sharpening procedure borrowed from another mower.

Storage and Seasonal Care

Definition: Good storage helps keep a mower ready for the next cut and protects the comparison from avoidable problems, such as packed grass or a damaged blade. Clean and inspect only after the machine is stopped, cool and secured according to its manual.

When the test is complete, let the mower cool before cleaning. Remove grass from the deck as directed, inspect the blade and guards, and store the machine dry. Follow the manual for fuel, battery or other storage steps that apply to the exact configuration.

For a seasonal comparison, record any service done before the test. Note blade sharpening, repairs and setup changes. That record makes the result easier to repeat and prevents a later run from being mistaken for a direct comparison when the machines no longer have the same condition.

A simple test log should include:

• Model, serial information and manual used
• Nominal deck width and measured cut height
• Turf type, moisture and grass condition
• Strip dimensions, pace and elapsed time
• Missed strips, clumping, scalping and turn handling
• Blade condition and any changes made between runs

Use the log to decide which mower suits your actual lawn, not to rank every mower of that width. The best choice is the one that delivers an acceptable finish and manageable mowing time on your terrain and through your access points.

Frequently Asked Questions

Definition: These answers cover the main points behind a 30-, 32- and 36-inch walk-behind comparison. Exact specifications depend on the mower’s model and serial information. Use the matching Exmark manual for adjustments and service, and treat width percentages as calculations rather than cut-test results.

Is a 36-inch mower always faster than a 30-inch mower?
No. It has 20% more nominal width, but turns, overlap, terrain and walking pace affect total mowing time. Test both on the same area.

How much wider is a 32-inch deck than a 30-inch deck?
A 32-inch deck is 2 inches wider, or about 6.7% wider by nominal width. That does not guarantee a 6.7% time saving.

How much wider is a 36-inch deck than a 32-inch deck?
A 36-inch deck is 4 inches wider, or 12.5% wider by nominal width. Actual productivity depends on the lawn and operator.

Is “Metro 30” the same mower as “Commercial 30”?
Do not treat those names as interchangeable. Confirm the exact model and serial identification, then use its matching Exmark manual.

What should stay the same in a cut test?
Use comparable turf, measured mowing height, similar grass moisture, the manual-specified engine speed and a consistent operator pace. Use each mower’s specified blade and deck setup.

Can I compare mowing times from different lawns?
Not fairly. Differences in lawn size, grass, moisture, slopes and obstacles can change the result. Use similar strips and record their dimensions and conditions.

What should I look for besides elapsed time?
Check missed strips, cut uniformity, clumping, discharge, scalping and ease of turning. Report open-area and tight-turn results separately.

What should I do after a blade hits a stone?
Stop the engine and wait for all motion to cease. Disable starting as the manual directs, inspect the blade and mower, and do not restart until the machine is safe.

Can deck width tell me the blade count or engine speed?
No. Blade count, blade part number, rated speed, height steps, torque and drive details can vary by model and configuration. Check the correct manual.

Which width should I choose?
Choose based on your measured test and the yard’s access, turns and open areas. A wider deck may suit broad strips; a narrower one may be easier to guide around tight obstacles.
