For maximum performance, each attachment is designed as a functional part of the tractor-attachment machine. QUICK-CHANGE ATTACHMENTS. All front-mounted attachments are secured to the tractor by just four bolts. Rear-mounted attachments are connected to the tractor by a quickly-installed rear hitch. UNIQUE SWIVEL ACTION. All Gravely attachments give you unique swivel action. The tool follows ground contours, regardless of the position of the tractor wheels, throughout its swath; this gives you a smooth, uniform job, whether you're mowing grass or scraping snow.
