Kubota Z452KWTi-60 EFI

The Kubota Z452KWTi-60 lets a buyer compare EFI with a carbureted Z400 without changing the nominal deck width. That makes it a useful counterpart to the Z422KWT-60: keep the cutting task constant, then examine starting, operator equipment and service support.

Compare the complete 60-inch packages

Kubota's 2026 US turf catalog lists a 26 gross hp, 726 cc FT730V EFI engine, ZT-3600 drive and a 6.8-US-gallon tank. Its 10 mph forward maximum is a travel specification, not a verified cutting pace.

The Canadian model page identifies the engine as Kawasaki FT Series GH730V EFI and confirms push-button starting. Preserve the engine plate information for service rather than assuming the regional naming is a different mower.

Ask the dealer to demonstrate the instructed start sequence and explain local EFI diagnosis. The EFI comparison guide helps separate convenience from unverified fuel-saving claims.

Check the operator package and footprint

The Canadian listing describes suspension seating and semi-pneumatic front tires. Have the quotation specify the supplied seat and adjustment range, particularly when comparing listings from different markets. Operator fit should be tested with the controls and deck pedal in their working positions.

The RCK60P-400Z deck is five inches deep, with a mechanical foot lift and quarter-inch height steps from 1.5 to 5 inches. Published equipped width is 73.6 inches. Measure accessories and the approach to storage as well as the opening.

The Z452KWi-54 is the narrower EFI alternative. Choose between them from the route, not an assumption that the wider model must save time on every lawn.

Keep fuel and warranty questions separate

EFI does not change the need for approved gasoline. Use the octane-and-ethanol checklist alongside the exact engine instructions.

The US warranty guide gives Z400 home use 48 months/500 hours and commercial use 24 months, with separate engine terms. Canadian buyers need the local policy.

Before purchase, have the dealer also check the engine specification and serial number against Kawasaki's applicable recall information. A family name alone cannot establish whether an individual engine is affected.

This model earns a place on the shortlist when the complete EFI package justifies its quoted premium. No comparative fuel-use or reliability result has been established.

Our ZT Score

7.8/10 — our research-based editorial assessment using the ZeroTurn scoring method.

• Cut quality (30%): 7.8/10. Five-inch-deep deck and fine height steps provide setup choices; finish is untested.
• Build & durability (25%): 8.0/10. ZT-3600 and documented Z400 hardware support the assessment; EFI alone does not prove longevity.
• Comfort (20%): 8.0/10. Documented suspension seating supports comfort credit subject to the supplied regional package and personal fit.
• Value (15%): 7.1/10. EFI starting convenience may be useful, but the delivered premium and fuel savings are unknown.
• Ease of use (10%): 7.9/10. Push-button start and foot lift aid routine use, offset by substantial equipped width.

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.
