parlty depends on what finish you want. if you want a stripe you need a roller. for a tidy finish you need to collect the clippings or cut very regularly. also depends how level the area is. if its rough have used a kuboto f3060 which is good but a bit of a beast for domestic work. will handle longer grass and uneven ground easily but clean filter behind seat frequently in dry weather or it will overheat. for level area and a good finish countax hard to beat. c series easy to use and turning circle good. use k series for a customer... has all bells and whistles, everything electic but not good in tight spaces. have fun...wish i had 11,000m2 (..do not covert your neighbours lawn...)
