Been doing some research on mowers for the past few weeks because I will be buying one in Feb. I have noticed that LOTS of the different companys offer the 19hp kawaski on the less expensive models. I need something to fit on a 5' trailer so I was looking for something around 48-52" deck. I came across the exmark lazer z hp 50" deck with 19hp kawasaki. I know someone that has a John Deere 60" deck 25hp kawaski and it bogs down a good bit in grass. since this happens, It leads me to wonder how a 19hp would do on only 10 inches less of a cut. All in all, How do your 19hp kawaski engines hold up on your riders? What inch cuts do you have them on??
