Compare Mowers
List prices are the manufacturer’s published figures, re-checked daily; they exclude tax, freight and dealer setup.
A side-by-side reference of each model's stated specifications. MowerFacts doesn’t give opinions: where a published, spec-derived rule can separate machines we mark a Data Pick and show the rule; here, read the values and decide what fits your needs.
Best suited for
What each model is built for, from its duty class and key specs. This is a neutral reference — MowerFacts does not rank one model above another.
- Kubota ZD1611 — commercial: daily paid use and high acreage; 60-inch deck
- Exmark Lazer Z X-Series (LRX 60 in 921) — commercial: daily paid use and high acreage; 60-inch deck; gas powered
What’s different? The 4 differences that matter most, from the published figures.
- ZD1611 uses a Kubota V1505-CR-TE5-ZD1 engine; Lazer Z X-Series (LRX 60 in 921) uses a Kawasaki FX921V engine. The engine maker builds the engine; the mower maker chooses the model, rating and fit, so the badge alone does not settle output or longevity.
- ZD1611 cuts from 1 in (25 mm) to 5 in (127 mm); Lazer Z X-Series (LRX 60 in 921) cuts from 1 in (25 mm) to 5.5 in (140 mm). The cut-height range is the shortest and tallest cut the deck offers. Most lawns are kept well inside it.
- ZD1611 has a published top speed of 10.6 mph; Lazer Z X-Series (LRX 60 in 921) has a published top speed of 11.5 mph, a 0.9 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- ZD1611 holds 13 gal (49.2 L) of fuel; Lazer Z X-Series (LRX 60 in 921) holds 12 gal (45.4 L) of fuel, a 1 gal difference. Tank size bounds how long a machine runs between stops. Consumption varies with engine, load and speed, so hours per tank are not fixed.
