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.
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.

- Gravely PRO-STANCE 60 KAWASAKI EFI — commercial: daily paid use and high acreage; 60-inch deck; gas powered
What’s different? The 5 differences that matter most, from the published figures.
- Walker Model H27i uses a Rehlko engine; PRO-STANCE 60 KAWASAKI EFI uses a Kawasaki® 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.
- Walker Model H27i weighs 748 lbs (339.3 kg); PRO-STANCE 60 KAWASAKI EFI weighs 940 lbs (426.4 kg), a 192 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Walker Model H27i's weight means for a trailer ›
- Walker Model H27i has a published top speed of 10 mph; PRO-STANCE 60 KAWASAKI EFI has a published top speed of 9 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.
- Walker Model H27i holds 9.4 gal (35.6 L) of fuel; PRO-STANCE 60 KAWASAKI EFI holds 9 gal (34.1 L) of fuel, a 0.4 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.
- Walker Model H27i has a 45.6 ci (747 cc) engine; PRO-STANCE 60 KAWASAKI EFI has a 44.3 ci (725.9 cc) engine, a 1.3 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
