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.

  • Wright Stander B 48 FS651E — commercial: daily paid use and high acreage; 48-inch deck; gas powered
  • Altoz XR 480 / 540 / 540 SS — commercial: daily paid use and high acreage; 48-inch deck; gas powered
What’s different? The 5 differences that matter most, from the published figures.
  1. Stander B 48 FS651E has a 11 Gauge deck; XR 480 / 540 / 540 SS has a Fabricated Steel deck.
  2. Stander B 48 FS651E has a published top speed of 7 mph; XR 480 / 540 / 540 SS has a published top speed of 8 mph, a 1 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
  3. Stander B 48 FS651E has a 22 hp engine; XR 480 / 540 / 540 SS has a 23 hp engine, a 1 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.
  4. Stander B 48 FS651E cuts from 2 in (51 mm) to 5 in (127 mm); XR 480 / 540 / 540 SS cuts from 1.5 in (38 mm) to 4.3 in (108 mm). The cut-height range is the shortest and tallest cut the deck offers. Most lawns are kept well inside it.
  5. Stander B 48 FS651E weighs 780 lbs (353.8 kg); XR 480 / 540 / 540 SS weighs 800 lbs (362.9 kg), a 20 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Stander B 48 FS651E's weight means for a trailer ›
