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’s different? The 5 differences that matter most, from the published figures.
- Turf Tiger II weighs 1,418 lbs (643.2 kg); 328G4 EFI weighs 1,140 lbs (517.1 kg), a 278 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Turf Tiger II's weight means for a trailer ›
- Turf Tiger II lists at $16,999 to $25,399; 328G4 EFI lists at $15,195, a $1,804 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 published top speed of 12 mph; 328G4 EFI has a published top speed of 10.5 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.
- Turf Tiger II has a 26 hp engine; 328G4 EFI has a 28 hp engine, a 2 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.
- Turf Tiger II has a 45.6 ci (747 cc) engine; 328G4 EFI has a 49.4 ci (810 cc) engine, a 3.8 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
