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.

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.
- Hustler Turf X-ONE — commercial: daily paid use and high acreage; 72-inch deck; gas powered

What’s different? The 5 differences that matter most, from the published figures.
- X-ONE uses a Kawasaki FX850, FX850 EFI 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.
- X-ONE has a 27 hp engine; Lazer Z X-Series (LRX 72 in 921) has a 31 hp engine, a 4 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.
- X-ONE has a 52 ci (852 cc) engine; Lazer Z X-Series (LRX 72 in 921) has a 61 ci (999 cc) engine, a 9 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
- X-ONE weighs 1,405 lbs (637.3 kg); Lazer Z X-Series (LRX 72 in 921) weighs 1,304 lbs (591.5 kg), a 101 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What X-ONE's weight means for a trailer ›
- X-ONE has a published top speed of 12 mph; Lazer Z X-Series (LRX 72 in 921) has a published top speed of 11.5 mph, a 0.5 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
