Product Overview
John Deere 7226Z front-mount scarifier attachment engineered for motor graders requiring hydraulic depth control, dual pitch, and float capability ahead of the moldboard blade. The V-type high-strength steel toolbar carries up to 9 heavy-duty 1" x 3" shanks across a 48-inch working width, fracturing compacted hardpan, gravel, and worn asphalt before the blade passes. Hydraulic cylinder provides lift to 23.2 inches for transport and depth control to 13.2 inches for penetration. Requires a John Deere motor grader with front auxiliary hydraulic lines and a compatible front nose mounting plate.

Applications
- Road maintenance contractor lowering the scarifier into compacted gravel ahead of the moldboard to fracture the surface before the grading pass - eliminating blade chatter and draft frame stress on a single run.
- Site prep foreman ripping hardpan clay or old asphalt on a civil construction site where the ground is too dense for the blade alone, working the scarifier to the full 13.2-inch depth before backblading.
- Municipal road crew lead breaking up frost-heaved or rain-rutted gravel road surface prior to re-grading, using the front mount position to keep the work zone directly in the operator's line of sight.
- Fleet mechanic at a public works yard bolting this unit onto the grader's front nose plate, routing the hydraulic hoses to the auxiliary valve block, and cycling the system before sending the machine back to the field.
- Heavy equipment repair shop expanding a John Deere grader's capability with a direct bolt-on front attachment rather than fabricating a custom ripper from scratch.
Frequently Asked Questions
What condition is this scarifier in?
Unused, New Old Stock. The unit was never mounted or operated. The powder-coat finish shows minor surface scuffs and storage marks consistent with warehouse storage. Surface rust bleed is visible at seams and on cast iron components. Hydraulic cylinder, hoses, and all fittings are intact and in excellent condition.
How many shanks are included, and can I add more?
Five serrated shanks are included and installed. The V-type toolbar has capacity for up to 9 total. Four additional 1" x 3" shanks can be sourced separately to reach maximum cutting density.
What hydraulic setup does the grader need?
The grader must have an open auxiliary hydraulic valve with lines routed to the front of the machine to actuate the lift and depth cylinder. Graders without front-routed auxiliary hydraulics will require an aftermarket hydraulic valve kit before this attachment can be used.
Will this fit my specific John Deere motor grader model?
The 7226Z is designed for John Deere motor graders with a compatible front nose mounting plate. Physical mounting plate bolt pattern and front frame dimensions should be measured and confirmed against your specific grader model before purchase. It will not directly bolt onto non-Deere grader brands without custom bracket fabrication.
What are the full cutting and lift specifications?
48-inch cut width, 13.2-inch maximum operating depth, 23.2-inch maximum lift height, 5.75-inch shank spacing, 1" x 3" shank dimensions.
A scarifier that never hit the ground is a rare thing in this industry - most of these are found welded solid, hoses cracked, zerks stripped from years on the front of a county grader. This one stayed in inventory instead, hydraulics intact, shanks sharp, waiting for the road that finally needs it.
