I have been running double blades on my 60" Turf Tracers with 23HP Kohlers for the last 2-3 years and this last week I went back to running single blades. I went with doubles originally (.250 gator over a .200 low lift blade) to lessen the amount of double cutting I needed to do and it seemed to work quite well. However lately I noticed I was still double cutting a fair amount anyway so I figured I would try going back to single blades (tried .250 gators). Also with singles I need to sharpen three less baldes per mower My thoughts so far as there is way less drag on the engine. The motor does not bog down nearly as much cutting though the tall stuff. The clippings are not as finely cut so even after a double cut they do not disappear quite as well as with doubles, I guess this was to be expected. I never really liked cutting with single gators and I was reminded of that this week I'm thinking of trying single high-lifts next week. I am also considering going back to doubles but running both .200 low lift blades thickness blades to try and minimize the load on the engine. Does anybody have any comments about going back to singles after running doubles? I would appreciate any information. Thanks.
