Is faster engine RPM ok?

I have a exmark lazer z hp 42 inch deck 25 hp Kawasaki. I was having alot of problems with my quality of cut and leaving alot of stragglers.

My rpm high idle not under load was 3400 rpm. My engine maunal calls for 3600. What I did was I set the idle a little high at about 3750 so that when I engage my blades I drop down to about 3650. Is this too fast? I didnt think 150 rpm would be that endangering of the engine but I just wanted a second opinion.

No problem...........what could it possibly hurt????
And besides, W.T.F. does Kawasaki know about YOUR machine.........right?

LOL ok thanks guys. I was just wondering becuase It does sound like the engine is going pretty fast. But thats probably because I have been used to it running at 3400 for a few months......

Why don't you sharpen your blades/or may sure ones not bent.

I am postive that nothing is bent. Blades are sharp. Deck is pitched to spec. My engine rpm was low and it cuts much better now. a couple hundred rpm can make a big difference.

You can do anything you want to anything you own, after all it is yours, you did pay for it and if it breaks you simply go get another.

Those Wakasakis now, they run probably, oh, about 2 thousand new.
But you can always get an inferior Briggs for like, almost half that.
Then you'll probably appreciate thata Wakasaki there

so I assume you do not think the extra 150 rpm for the little bit it runs untill the blades are engaged to bring the rpm back down to 3600 is good for it?

The only thing you might want to do is change the oil a little bit earlier than your normal maintanance.
