Can those of you that have 17hp & 19hp Kawi's help me out? How much do you think it's really worth ($) to upgrade from a 17 to a 19? I have NO prior experience with Kawi engines. All I have ever owned is Kolher and Briggs. With some Kolher engines I have noticed little or no difference between 2 HP. With Briggs, I have seen one labled 17hp and an identical one labeled 21hp. So no difference but the sticker. I don't know if this is the case with Kawi or not. I'm excluding brand names and giving correct or approximate figures for reasons that should be obvious. TO PREVENT A BRAND WAR. Now to the specifics of what the engine load will be... Mower A 17hp 44" cut, 23x9.5-12 tires, around 1000lbs Mower B 19hp 44" cut, 20x10-10 tires, around 1000lbs Mower C 17hp 48" cut, 20x10-10 tires, around 800 lbs I weigh 200 lbs I'd I will be running a mulch kit most of the time. I tried to take those numbers and figure out where each mower ranked as far as engine load is conserned so I wouldn't have to post all this. But all I did is confuse myself. :blush: Please help, because if everything goes as planned I need to snatch one of these ASAP!
