I just went from a Turf Tracer HP to a Turf Tracer S Series and the new mower takes a different blade, the bolt hole is 15/16" instead of the 5/8" on the old mower. I've got a lot of sets of blades, I have a guy that does an AWESOME job sharpening them for me (for only $4/blade!) and I can drop off 5-7 sets of blades once a month or so. So, I found a 15/16" drill bit on Amazon for $10; I have a drill press; would simply drilling out the holes work? Would a $10 bit last to drill 18 holes? Anyone ever tried it? I did a search and didn't get any hits. Thanks!
