Just bought a couple sets of highlift Oregon blades the other day. These blades are much wider than my older blades. They seems to slow the engine down in some of our more weedy lawns. I had them on the 27hp Kawi first and I thought it may just be the engine but it does the same on the 29hp Kawi. So my question is: Anyone else running the high lifts, or super high lifts, notice any of the same problems when cutting? The cut looks really good and the discharge is nice and even, it just takes a little longer to get everything done because you have to run slower. Running them on 2 Turf Tiger 61''. Thanks.
