What is the main difference in the Quick 36 SuperSuty and Quick 36 Samurai?? I emailed Gary and he told me that it is basically how much money you want to spend and that they are both excellent machines. He said that the Samurai is more costly to maintain and the parts are harder to come by for the engine... It seems like the SuperDuty would do fine if only mowing 15 yards a week.... or maybe not???????
