Hello beantin
Many thanks for this topic.
On domestic lawns, de-thatchers are little understood.
Yet they produce amazing results for the effort.
I think the nylon tines will be fine - given lawns generally only require once-a-season de-thatching.
This is not a professional machine - but a top-end domestic job.
Any advice welcome.
I think you have made an intelligent decision here.
Please keep us informed as to use and lawn results.
It is unclear who makes the Kwikthatch.
Cheers
