this didn't get off to a good start when I got an error from the web site when processing the order. I re-entered my details and the order went through fine, but then the first order popped up in my emails as well! I emailed Mow Direct to say what had happened and asked to cancel one of the orders. I then phoned them and explained, and they agreed to cancel and refund one. However next day 2 machines arrived! the courier took one back, however 2 days later the unwanted one was delivered back again. I called again and the order was eventually collected and payment refunded. tried the machine out a couple of times on our cricket wickets and it is fantastic! on the highest settings the blades "verticut", just cutting across any thatch or horizontal growth and improving the grass surface but without actually digging into the soil beneath. on a lower setting the machine cuts the surface for proper scarification. the engine seems plenty powerful enough, although I haven't tried it on the lower settings and on very hard ground. the grass collector works reasonably well but you will need to go over the area with a mower to remove all the thatch that's been removed. so far very happy!
