John Deere's D-Series motor graders have been updated with enhancements designed to deliver a boost in productivity. These improvements include a mid-mount scarifier for the 670D, 672D, 770D and 772D (pictured) machines; an integrated grade control package that is designed to save installation time and provide professional integration for the D-Series line; and for all-wheel-drive machines, a new low-speed precision mode and improved steering.

The mid-mount scarifier option comes equipped with a full set of 11 teeth and is mounted between the blade and the front wheels. Both the front-mount scarifier and the rear-mount ripper-scarifier are offered as well.

“John Deere's updated graders now offer sturdy and durable mid-mount scarifiers with a V-shaped design and improved balance,” says Jeff Rowan, product marketing manager for motor graders for John Deere. “The attachment is not only heavy-duty, it gives ground penetration and visibility.”

The all-wheel-drive machines (672D, 772D, 872D) provide a precision mode that lets the operator proceed at a super-slow speed. Because of the hydrostatic front-wheel drive, the operator can dial down the tractor speed in first, second and third gears to about one-quarter mile per hour. “This slow ground speed allows the operator to do really fine, precise grading,” Rowan says.
