Gravely ZT XL 42 Kawasaki

The Gravely ZT XL 42, model 918012, is a useful comparison for someone already considering the ZT X 42. Both offer a compact cutting width, so the XL decision should focus on the drive, seating equipment and coverage rather than assuming the higher series will finish the lawn faster.

What the XL changes

The Gravely catalog identifies the 42-inch XL with a 21.5 hp Kawasaki FR651V, 726 cc displacement and Hydro-Gear ZT-2800 transaxles. Its listed maximum forward speed is 7 mph, with a 3.5-US-gallon tank.

The ZT-2800 is the meaningful drive distinction from the ZT X configuration reviewed on this site. That does not establish a particular service life, nor does it mean the ZT X lacks all maintenance provisions. Obtain the correct service schedule for the supplied serial number and compare the work involved.

Buy the seating equipment you actually tried

The catalog lists a 22-inch high-back seat with padded armrests and seat isolation. Tool-free control-arm adjustment helps fit the controls to the operator. Isolation should not be described as full chassis suspension; the suspension guide explains the difference.

Try reaching the lift pedal while maintaining a comfortable position at the controls. If the dealer's machine differs from the catalog package, have the quotation identify what is included. A trim name cannot replace that equipment check.

Keep the 42-inch deck decision practical

The 11-gauge fabricated X-Factor deck has thirteen settings from 1.5 to 4.5 inches, adjusted with a foot-operated lift. Those features provide setup choices; we have not measured its finish against another mower.

Published overall width with the chute is 56.2 inches. Measure the actual access route and the supplied machine before purchase. Catalog and operator-manual length and weight figures differ, so this review does not combine them into a supposedly exact transport specification.

The ZT XL 52 is the wider alternative when open mowing area warrants it. Its deck and engine configuration should be compared separately.

Where it fits

The current product listing still identifies 918012. The cited documentation lists four-year/400-hour residential coverage; commercial use and individual components have different terms. Confirm coverage for the country and machine being sold.

Shortlist the XL when its ZT-2800 drive and documented seating equipment solve a real ownership need. A matched delivered quote and demonstration are necessary to decide whether that upgrade is worth its cost.

Our ZT Score

7.6/10 — our research-based editorial assessment using the ZeroTurn scoring method.

• Cut quality (30%): 7.7/10. Fabricated X-Factor deck and 13 settings support setup; finish is unmeasured.
• Build & durability (25%): 7.7/10. ZT-2800 drives and welded construction strengthen the residential equipment package without a longevity claim.
• Comfort (20%): 7.8/10. Tall seat, padded armrests and isolation are useful fit features; ride benefits remain untested.
• Value (15%): 7.1/10. The drive and seating upgrade can be useful, but its delivered premium over a matched ZT X is unknown.
• Ease of use (10%): 7.8/10. Tool-free control adjustment and foot lift help daily use; exact dimensions require confirmation.

Provisional research-based editorial assessment, not a hands-on test. Cut finish, ride, fuel use and service life have not been measured. Reliable model-specific owner consensus and comparable delivered US/Canadian prices were not established. Value remains conditional on local support, supplied equipment and the intended work.
