Metabo Grinding Shrouds work in conjunction with vacuum systems to reduce silica dust exposure during concrete surface grinding. The shrouds help protect users from excessive silica dust exposure in accordance with OSHA regulations. Made of polyurethane, the device is designed to retain its shape regardless of temperature and will not warp. The 5-in. grinding shroud will fit 4-in., 41⁄2-in. and 5-in. diamond-cup wheels, while the 7-in. grinding shroud will fit most large-angle grinders. Mebabo; 800-638-2264; www.metabo.us
The Cat 973D track loader features load-sensing hydraulics with a variable-displacement pump that produces only the necessary amount of oil for the job at hand, which not only conserves fuel by pumping less oil but also frees up horsepower to drive the tracks more efficiently. The load-sensing system also allows for seamless use of lift, tilt and travel functions. The redesigned cab of the 973D features a choice of joystick or pedal steering, and the cab itself tilts for improved visibility. Caterpillar; 309-675-1000; www.cat.com
