Kurtis from Cutting Edge Engineering is working on a 672 Grader, which is in good condition despite its high number of hours. The customer wants to prolong its life, so Kurtis is fitting a wear skin to the blade and replacing the bottom guide on the back of the blade to ensure accurate GPS cutting.
Kurtis removes the blade, takes it inside, and begins fitting the wear skin, using 8 mil 450-grade wear plate. After welding the skin onto the blade, he adds a hard-facing layer to prevent erosion.
Next, Kurtis replaces the bottom guide, using a new piece of Biz 80-grade plate, which he machines to size using a Zayer. He then welds the new guide onto the blade and reattaches it to the grader, adjusting the top clamps and brass guide blocks.
Finally, Kurtis fits the GPS pole and completes the job, which should add many more years to the blade's life.
