Thanks for all the great input when I was asking questions for my new ZTR mower. Question I have now is why a commercial grade mower like the Exmark I just bought is putting only a 19 HP Kawasaki Engine on it when littler Gravely ZT series, Hustler homeowner series and Simplicity, to name a few, are building machines that are smaller with larger HP engines like 21 and 23 HP? Am I going to be displeased with the 19 HP V-Twin Kawasaki engine or is there something I'm missing? The machine seems to cut great so far but I am worried I may be short on power if I really need it in heavier grass, etc. Can someone shed some light and their thoughts on the power source on the Exmark and the differences between the larger HP engines on the smaller machines? Am I worrying about something I shoudn't? I wouldn't assume a company as reputable as Exmark would cut corners and sacifice performance when everything else they do seems to be high quality? Thanks all.
