Hi Boonta92, will keep you in mind in a few months as I may need to have some stuff cut.
One thing I would suggest you look at is a swing back blade conversion kit for a few of the more domestic ride on mowers. Not a big market but it is untapped
Things like the masport/rover mini riders in 30in sizes don't have a solution to mount swing blades. on a 24in micro rider, you can use a ga spares blh5826 and some rover rider blades to make up 24in, but no solution for the 30's. Probably not a massive market but I can think of a few dealers who would probably like them
basically one of these but about 3in longer
When I have some time in a month and a bit, I am quite happy to lend you an old one I have here and a pair of rover blades to you could work out a solution
