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.

What’s different? The 5 differences that matter most, from the published figures.
- Vertex S-Series (52 in EFI) uses a Kohler ECV740 engine; F2690E uses a Kubota D1105 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.
- Vertex S-Series (52 in EFI) weighs 987 lbs (447.7 kg); F2690E weighs 1,594 lbs (723 kg), a 607 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Vertex S-Series (52 in EFI)'s weight means for a trailer ›
- Vertex S-Series (52 in EFI) holds 8 gal (30.3 L) of fuel; F2690E holds 16.1 gal (61 L) of fuel, a 8.1 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.
- Vertex S-Series (52 in EFI) has a published top speed of 8.5 mph; F2690E has a published top speed of 12.5 mph, a 4 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- Vertex S-Series (52 in EFI) has a 45.6 ci (747 cc) engine; F2690E has a 68.6 ci (1,124 cc) engine, a 23 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
