Gravely ZT X 48 Kawasaki

A 48-inch deck can fit a property well before the buyer has settled on a drivetrain or seat package. The Gravely ZT X 48 Kawasaki makes that distinction useful: compare it directly with the XL 48 instead of assuming that moving up a series is mainly about cutting width.

What the X package includes

Model 918009 uses the 21.5 hp, 726 cc Kawasaki FR651V and serviceable EZT transaxles. Gravely's current ZT X sheet documents oil-change ports, a 3.5-US-gallon tank and a 7 mph forward maximum.

The ZT XL 48 changes to the FR691V and ZT-2800 drive. Its seat isolation is another comparison point. Ask the dealer to identify these differences on both quotations; neither the same deck width nor the presence of service ports makes the two drive packages equivalent.

Decide whether 48 is the useful compromise

The fabricated 11-gauge X-Factor deck has thirteen cutting positions from 1.5 to 4.5 inches and a foot-operated lift. Compared with the ZT X 42, the extra span should earn its place on the actual mowing route.

The 48's listed width is 62.3 inches with the chute and 51.1 inches without it. Use the complete supplied configuration for clearance planning. Removing discharge protection is not an acceptable way to make a mower fit while cutting.

Try the adjustments before buying accessories

The standard specification includes a 22-inch high-back seat with armrests and a slider, plus tool-free control-arm adjustment. A seat isolator appears in the accessory list. Try the standard seat first, and have any requested upgrade itemized rather than assuming it is included.

A useful demonstration includes reaching the deck pedal without shifting awkwardly, getting on and off, and checking the permitted access route. The dealer-demo checklist can help organize those observations.

Published unit coverage is three years or 300 hours, subject to the full policy. This is a residential buying comparison: select the X when the supplied equipment and local support satisfy the job. We have not verified a delivered price saving over the XL or measured a difference in mowing results.

Our ZT Score

7.4/10 — our research-based editorial assessment using the ZeroTurn scoring method.

• Cut quality (30%): 7.7/10. Fabricated deck and thirteen height positions aid setup; no cut test establishes superiority.
• Build & durability (25%): 7.3/10. Welded frame and oil-service access are useful features, with EZT kept distinct from the XL drive.
• Comfort (20%): 7.3/10. High-back seat and armrests support operator fit; optional isolation is excluded.
• Value (15%): 7.1/10. Same-width comparison makes the upgrade decision clearer, but delivered savings remain unknown.
• Ease of use (10%): 7.8/10. Tool-free controls and foot lift help adjustment, with less width than the 52 but a chute clearance check still required.

Provisional research-based editorial assessment, not a hands-on test. Cutting results, ride quality and service life have not been measured. Model-specific owner consensus and comparable delivered US/Canadian prices were not established. Value depends on the actual configuration, property and local service support.
