I purchased a Troy-Bilt Trailblazer at a farm auction this winter. I was under the assumption they were still being manufactured. I found out quickly that they were not and finding parts for it was going to be a pain. The mower ran great, but the sickle sections needed to be replaced. I searched MTD's (troy-bilt) website, no luck with anything. Ebay and some other internet sites had sections for it, but WOW they were expensive - $5 to $10 a piece for a 2 inch section, not to mention the rivets. I did some more searching and as luck would have it Good Ol' John Deere makes a double section (4 inch) they call Dura Twin, that with a little work would match. These sections are readily available at any JD dealer and come in course or fine cuttings. They cost me about $2.50 a piece, which being a double section, was under a 1/4 of what two, 2 inch sections cost. I bought a box of 5 1/2 (wire size, not inches) by 5/8 inch rivets for $2.83. This was by a pound which probably had over 200 rivets in it. This thread will describe how to retro fit your Trailblazer to accept JD sections on it.
