Trust me Jeff there are a lot of people out there who should not even use domestic mowers. Half acre of kikuyu it will handle easily. I saw this one on Gumtree , hasn't done much work, these are $900 new and obviously just a poor quality toy, only comes with a bar blade so has no spinning mass to help it get through long grass, not really a slasher, just an imitation and fitted with a problematic Briggs motor, just ask Speedy.
