Claims18
An apparatus for scraping hardened filling material deposited in a joint or crack of a concrete surface, the apparatus comprising:
- a) a power-driven cart for advancing the apparatus along the concrete surface in a forward direction;
- and
- b) a scraping arrangement mounted at a front region of the power-driven cart, the scraping arrangement being configured to scrape excess portions of the hardened filling material to provide a filling material surface that is generally flush with the concrete surface, the scraping arrangement including:
- i) a first extension member having a first rigid blade, and a second extension member having a second rigid blade, each of the first and second extension members extending forward from the power-driving cart such that the first and second blades contact the concrete surface;
- ii) wherein the first blade is positioned in front of the second blade.

- and
- b) a scraping arrangement mounted at a front region of the power-driven cart, the scraping arrangement being configured to scrape excess portions of the hardened filling material to provide a filling material surface that is generally flush with the concrete surface, the scraping arrangement including:
- i) a first extension member having a first blade, and a second extension member having a second blade, each of the first and second extension members extending forward from the power-driving cart;
- ii) wherein the first and second blades are oriented at an angle less than about 45 degrees relative to the concrete surface, the first blade being positioned in front of the second blade.
