I am particularly interested to see who has used the 30" 1 blade walkbehind. How was the cut? Did you have to trim less than when using a 36" walkbehind? The front wheel design seems like it would facilitate less trimming.
They were at the Louisville expo inside, didn't see them outside, not that it would have mattered since none of the mowers outside in the test area had blades because of safety rules. But I think they might be good for small highly landscaped yards and fenced back yards due to: 1. the fact they weigh less than typical commercial units (no rutting in wet grass) 2. smaller front wheels enabling cutting closer to objects with less trimming. 3. Cut much faster than the 21" finish mowers many people use.
I am trying to find one that I can demo but there are only a few places in Indiana that are listed as dealers and none had one in stock at this point of the season.
the thing I don't like about a one blade mower with a blade that large, is that in tougher grasses that are more stringy, the blade may not leave as clean a cut, because there are much less rpms.
say we are running at 3600 on the engine and we will assume that the spindle is turning at the same speed as the engine, and we have a 30" blade. so then:
30X3.14X3600= 27,060fpm, but that would not qualify for ansi, so I am assuming that they have got the fpm speed down to at least 19,000fpm at that fpm speed, with a 30" blade, I am coming up with the blade spinning at 201rpm, that can't be right, but I used 19,000fpm/pi/30" that is the right operation yes? if it is 201 rpm, that is a REALLY slow blade, and woldn't not take out gooses grass very easily.
