The Kawasaki FX921V 31 hp engine on your Cheetah is classified as a big block engine, the same as the FX1000V which is the old 37, but is now listed as 35 hp. They are all 999cc engines, and are naturally going to use more fuel, but in return should produce more work with time saved.

cm3 stands for "cubic centimeter"

no that would be much better then what i do, generally i sharpen my blades once a week or every other week, but for the last 12 weeks, i haven't changed or sharpened my blades once, still original blades, probably pretty dull, i found if the deck is clean which i have spent a few mins literally about 2 mins cleaning in the 73hrs on my machine, it still cuts great and doesn't miss many blades, whatever it misses gets double cut or if there are any grass clippings showing at all, usually the latter of the two happens on my really thick lawns that grow 8 inches in a week. i have new blades, but i've been lazy lately, once september hits i'll be out of summer mode.

I talked with the Bobcat engine specialist yesterday because of wondering why they only offered the FX1000-DFI on their Predator Pro. He told me they went through extensive testing to gather fuel usage numbers, and the fuel injected model was so much more efficient they saw no reason to offer the carburetor style engine.

He said they had seen numbers down into the 1 gph range on the big block fuel injected engine. I find that somewhat difficult to believe, but then again I did not do the testing. I would say from what I was told, if a person had a choice; he should definitely go with the Kawi 37 hp DFI engine. I think it would really be a no brainer, if you can get better fuel economy while achieving more hp, to me that is the only way to go.

Don't feel bad. I installed a set of G6 Gator blades back in April. I finally swapped them out for the OEM blades after a few months of mowing. I was being lazy. I still need to throw an edge on the G6 blades. They seem to cut better then the OEM blades. I've been very busy and by the time I get home I'm done. 42 straight days of work is starting to wear on me.

Ive told folks this for the longest time........... You don't need crazy sharp blades as long as your deck (velocity plus anyways) is clean. we mow over 70 places per week approx 25hrs per mower and have gone months without sharpening blades. Yes they are dull but yards still look FANTASTIC. As soon as the deck starts getting loaded, thats when bad cut comes in. Don't get me wrong, I thinnk sharp is the way to go but ill be dammed if im gonna sharpen blades weekly if I can't tell the difference in the cut. And we don't...........

this is true, the deck creates most of the lift, so a clean deck will cut good, dirty deck will cut like crap no matter how sharp the blades are. none of my customers complain and i don't leave stragglers every blade of grass is still cut so its all good.

Thoughts, comments or pictures please
John Deere makes a good t- shirt. I own one scag walk behind. You will find no shortage of Scag lovers on this site, that is for sure. I'm a diesel Kubota man myself. After having my first Kubota for a year, I bought a second one. I went in the local Kubota dealer and told them I would never buy another scag again, he replied , " I've worked here for nine years and I hear somebody say that at least once a month" . Btw I am a second generation scag owner in my family.

I bet JD makes more profit from all the clothing and caps than all their equipment combined.
