You own the BEST tiller in the business, why not own the BEST tines for your Troy-Bilt Tiller. K-D Tines are the best replacement tines out there and have been since 1983. Our tines will fit ALL Troy-Bilt Horse, Econo-Horse & Pony rear tine tillers old or new. Unfortunately they will not fit Junior, Bronco or Tuffy tillers. Our standard tines are 6mm thick which are heavier than the original tines but the hard-faced tines are our standard with an extra welded bead at the bottom of the tine for longer life. Our tines, just like your original tiller tines, have only 2 holes which are much stronger, unlike the universal 3 hole replacement tines they have on the market today. Take a solid piece of raw steel and drill an extra hole in it and you just created a weak point, let that tine come into contact with a hard root or rock and SNAP!, it breaks right in two. Our tine sets are complete. You will receive 8 left hand & 8 right hand heat treated painted (like original) tiller tines, 16 coated (resist rust) bolts,& lock nuts. We have also included instructions for all of you do-it-yourselfers out there. No reason to pay somebody, do the easy installation yourself and take pride in that. LIFETIME WARRANTY AGAINST BREAKAGE! Yes you will wear your tines out but if a tine ever breaks, just send it back in to us and we will replace it for free - you only pay the shipping. We ship all purchases within 1-2 business days.**If your package shows delivered to correct address as ordered - shipping Insurance does not cover stolen packages**
