I'd like to get everyone's opinions on the Honda 21" commercial with the hydrostatic drive vs Toro's 21" commercial. How do the two compare? If possible, does anyone know what the top speed of the Honda hydro is? There literature seems to suggest a top speed of 4.1 mph or 6.6 km/h? But my dealer says he can increase the speed beyond that figure because of the hydro drive. Who is right?
