[quote=Tyler]I have converted a victa sprinter into my dedicated dethatcher. Most useful application I have found for a sprinter.
made it myself - just drill 4 holes in total. the outer holes are 10mm in from each end of the blade, the inner holes about 30mm inwards from those. drill about 10mm back from cutting edge.
loop a 80-100mm length of 5mm trimmer line (like for the big DR walk behind string trimmers) through the holes and ensure the ends have the same depth. I find a pair of 'tines' last about 200-400sqm.

Oh nice, might have to give that a shot, thanks for the suggestion :). Regarding the holes, what size hole do you drill? 5mm, same size as cord, or a little smaller so the cord is more tight fitting?
I came across this one which seems similar to what you did with yours. https://youtu.be/nhR0OsVeZ18
[quote=sb30inch]Hi Widget and Tyler.I modified a victa the same as Tyler but used some high tensile bolts instead of the line.Seemed to work ok.I have a dedicated scarifier so use that most of the time.[/quote]
Thanks for the suggestion sb30inch :). I saw a video similar to what you did https://youtu.be/8-4MsJDzkgY. One thing I'm not sure about though is, if you're using a bar-blade with bolts, if you were to hit something hard or catch a thick root, what are the chances of the force being transferred either into the bar-blade (bending it) or into the crankshaft ?
Thanks for the suggestions, I might have a look for a spare blade and go from there :).
