I have mowed twice with the SB45 over the last week. First time at 20mm (as mentioned in previous post). Took a lot of grass clippings off. I then did back to 15mm and took about the same amount of clippings off again. The lawn is mostly brown now and I am hoping it is OK. I want to mow one more time before the green bins (I have 2 large) go out on Sunday. That leaves me with 2 green bins and I plan to do the scarification process. I expect I will need more than the two bins, but hopefully that does most of it. I am watering a lot and it is pretty hot in Sydney at the moment, so I think the grass should come back quick when it does.
Just a question... When you scalp it, you mow away the green leaves and are left with brown. Where were the leaves growing from? Were they coming from the living tendrils in the thatch, or were they growing through the thatch from the soil underneath? By dethatch, are we removing living parts of the grass as well as old thatch that have died?
