That's exactly what i use to cut mine, kept sharp clean, and maintained they can last forever. also properly adjusted..
They work fine if you cut before the grass gets too high for the reel to catch it. And they work just fine in MOST grass types, really dense grasses tend to make it hard, (like the damn bermuda grass in my back yard i can't get rid of), but no gas,, no noise, SAFER!!!!!,and you could cut your grass at midnight without waking the neighbors!
I use valve lapping compound to keep the blades sharp, put it on the reel, and turn it backwards, pressure of the cutting bar against the reel is VERY important. Once you get it right it will cut paper better than scissors (which is what i use to test the sharpness)
I inherited both my reel mowers because of poor adjustments, too tight and too hard to push!
