Spring Lake, MI | As the other poster has said... your scraper is set up in the most common configuration. When the center bit is in the lower position it commonly called a "frost bit." It is not uncommon for contractors to use them in this position, and then move the center up for a smooth cutting surface for final grade.
A few things just in case you are new to scrapers:
1) the blades are double-sided. Note that your center bit has already been flipped.
2) note how close to the bolt holes the previous side was worn. That is quite common. In my experience, as long as you flip blades (or install new) before you wear on the frog, you will be fine.
3) the frog is the frame of the scraper that holds the bits.
4) your side bits and center bit appear to have a lot of life in them.
5) same for the router bits. Those are the vertical cutting edges on the outisde edge of the scraper bowl. They are also flippable.
6) good quality (CAT, Bucyrus, etc.) blades are self-sharpening. The front surface is harder than the back of the blade. This not only helps them stay "sharp" but also provides much more strength to resist cracking than if the blades are completely hardened. Some cheaper blades are punched for the plow bolts from both sides... good ones will be punched so the plow bolts can only be inserted from the front.
7) in my experience, CAT has been about as cheap as anywhere to get blades. Just ask for blades for a 2Wxxxx scraper. I can check my parts book, but there should be several options from one piece, two piece, and three piece (as you have). Not all blades have two sets of holes for upper and lower positions ... so pay attention to that when ordering new blades.
8) when ordering new blades, get new hardware. I am comfortable reusing hardware when flipping, but new blades get new hardware including nuts and lock washer.
9) remember: those were designed to be pulled by a D6 and pushed by another D6. If your gooseneck ball and swivel hitch are in good adjustment, you won't have trouble. | |
