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.

What’s different? The 5 differences that matter most, from the published figures.
- Diesel Z uses a Perkins engine; Lazer Z X-Series (LRX 72 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.
- Diesel Z weighs 1,711 lbs (776.1 kg); Lazer Z X-Series (LRX 72 in 921) weighs 1,304 lbs (591.5 kg), a 407 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Diesel Z's weight means for a trailer ›
- Diesel Z has a 25 hp engine; Lazer Z X-Series (LRX 72 in 921) has a 31 hp engine, a 6 hp difference. Published horsepower is the maker's rating at a stated engine speed. It is a different measure from displacement, and two engines of equal rating can pull differently.
- Diesel Z holds 14.4 gal (54.5 L) of fuel; Lazer Z X-Series (LRX 72 in 921) holds 12 gal (45.4 L) of fuel, a 2.4 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.
- Diesel Z has a 69 ci (1,130 cc) engine; Lazer Z X-Series (LRX 72 in 921) has a 61 ci (999 cc) engine, a 8 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
