I use a sthil Deweeder machine with a paddy cutter attachment. The paddy cutter attachment is a local one which costed me Rs 3500.
Its pretty easy to cut, I tried it for the first time and found that work finished very fast.
The result is better if the grass is tall.
However my labourers were not very happy. They said that lot of paddy would fall off, but that was not clearly evident. The other concern they raised was that it was difficult to make it into lots to be loaded into tractor. However I do not buy that argument.
I will try to upload the video tomorrow
The tiller attachment for Sthil is around 18 K which is very expensive. I use a Mantis tiller which I got for 32K but felt it is much better.
