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 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.
- Turf Tiger II has Dual Pump and Motor drive; PRO-TURN 552 KAWASAKI has Hydrostatic drive.
- Turf Tiger II has a published top speed of 12 mph; PRO-TURN 552 KAWASAKI has a published top speed of 15 mph, a 3 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- Turf Tiger II lists at $16,999 to $25,399; PRO-TURN 552 KAWASAKI lists at $14,999, a $2,000 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- Turf Tiger II has a 45.6 ci (747 cc) engine; PRO-TURN 552 KAWASAKI has a 52 ci (852 cc) engine, a 6.4 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
- Turf Tiger II has a 26 hp engine; PRO-TURN 552 KAWASAKI has a 27 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.
