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’s different? The 5 differences that matter most, from the published figures.
- Stander ZK 52 FX820 has a 50.2 ci (822 cc) engine; Vertex X-Series (52 in) has a 61 ci (999 cc) engine, a 10.8 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
- Stander ZK 52 FX820 weighs 1,110 lbs (503.5 kg); Vertex X-Series (52 in) weighs 1,250 lbs (567 kg), a 140 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Stander ZK 52 FX820's weight means for a trailer ›
- Stander ZK 52 FX820 cuts from 1.5 in (38 mm) to 5.5 in (140 mm); Vertex X-Series (52 in) cuts from 1.5 in (38 mm) to 5 in (127 mm). The cut-height range is the shortest and tallest cut the deck offers. Most lawns are kept well inside it.
- Stander ZK 52 FX820 holds 15.5 gal (58.7 L) of fuel; Vertex X-Series (52 in) holds 14 gal (53 L) of fuel, a 1.5 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.
- Stander ZK 52 FX820 has a published top speed of 12.5 mph; Vertex X-Series (52 in) has a published top speed of 12 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.
