Anyone ever used an All Flex mower?

[KYMan]

I've been thinking about buying on of these for a while now. http://www.landpride.com/products/78...ll-flex-mowers

I'd like to be able to get the local soccer/recreation parks and a few factories which would generate about $1300-$1500 a week in income. How is the cut? How many acres per hour? also...what is total length when hooked up to tractor? I plan on buying a 20 ft equipment trailer for this and my Kubota L3800 but that 20 ft looks like it may be too short. Also, any kind of maintenance issues?

Thanks
