I got a FH680V 23hp kawasaki that has around 1000hrs on it. Here in Louisiana it gets really hot in summer time. I have always used mobil 10w-30 oil from day one. Will it hurt anything to change oil grades to 15w-40 mobil fleet?

I use Rotella T6 in the 20HP Kawasaki in my John Deere 425. A 15W-40 HDEO should work great if it's never used in below freezing temps.
If 10w-30 is working great why change?? If you want something good you might want to look towards Castrol Edge 0w-30 (German Castrol). It is nearly a 40 wt and has good cold cranking viscosity. It has been proven to work very well in OPE especially air cooled.
