The new family of box blade attachments built by Bobcat is available in three 84-inch models. There's a laser box blade, that same box without the laser, and a basic box blade without front casters. Moving the center switch on the carrier-machine's right control lever right or left raises and lowers the bolster and blade. The laser system is integrated into the high-end model (at a total price of about $8,000), and produces grade accuracy of plus or minus ¼ inch.
