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.
- Grasshopper 735BT — commercial: daily paid use and high acreage; 52-inch deck; gas powered
- Gravely PRO-TURN ZX 52 KAWASAKI — commercial: daily paid use and high acreage; 52-inch deck; gas powered
What’s different? The 5 differences that matter most, from the published figures.
- 735BT lists at $18,550; PRO-TURN ZX 52 KAWASAKI lists at $9,899, a $8,651 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- 735BT uses a Vanguard engine; PRO-TURN ZX 52 KAWASAKI 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.
- 735BT holds 7.2 gal (27.3 L) of fuel; PRO-TURN ZX 52 KAWASAKI holds 5.1 gal (19.3 L) of fuel, a 2.1 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.
- 735BT has a 60.6 ci (993 cc) engine; PRO-TURN ZX 52 KAWASAKI has a 44.3 ci (726 cc) engine, a 16.3 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
- 735BT has a published top speed of 10 mph; PRO-TURN ZX 52 KAWASAKI has a published top speed of 8.5 mph, a 1.5 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
