- IS6200 Zero Turn Mower uses a CAT Turbo Diesel engine; Stander ZK 72 FX820 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.
- IS6200 Zero Turn Mower has a 103.7 ci (1,700 cc) engine; Stander ZK 72 FX820 has a 50.2 ci (822 cc) engine, a 53.6 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
- IS6200 Zero Turn Mower has a 48 hp engine; Stander ZK 72 FX820 has a 34.5 hp engine, a 13.5 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.
- IS6200 Zero Turn Mower runs on Diesel; Stander ZK 72 FX820 runs on Gasoline. Fuel type sets what you buy and store; it is not a measure of power.
